Maintaining Railway Safety Standards with Reliable Earthing Material
Railway safety is of paramount importance, and ensuring that all components of the railway system are functioning properly is essential to achieving it. One of the most critical components in ensuring railway safety is reliable earthing material. In this blog, we will discuss the importance of railway earthing material and how it helps maintain railway safety standards.
Why is Railway Earthing Material Important for Safety?
Railways operate on high voltages, and proper earthing of the system is necessary to protect against electrical hazards. When a railway system is not adequately grounded, the electrical current may escape through the rails or other conductive materials, creating a potentially dangerous situation. By contrast, when the railway system is underground properly, the current is safely flown into the ground.
Types of Railway Earthing Material
There are several types of railway earthing materials, each with its own specific use. Some of the most commonly used materials include copper or copper-clad steel wires, grounding rods, and ESE lightning arresters.
ESE Lightning Arresters
An ESE (Early Streamer Emission) lightning arrester is a type of lightning protection device designed to minimize the risk of lightning damage to structures and equipment. Its primary function is to intercept and control the initiation of a lightning strike to a protected area, such as a building or installation.
ESE Lightning Arresters are becoming increasingly popular in the railway industry due to their effectiveness in protecting against lightning strikes. ESE Lightning Arrester use the principle of Early Streamer Emission (ESE) to capture and discharge lightning strikes to the ground, protecting the railway system from damage. ESE Lightning Arresters are ideal for use in open areas where the risk of lightning strikes is high.
The ESE lightning arrester by Ennob is a cutting-edge device designed to protect structures from lightning strikes. Employing advanced technology, it provides early and efficient streamer emission, ensuring rapid discharge of atmospheric charges.

Ground Rod Maintenance: Tips for Long-Term Performance and Safety
Ground rods play a critical role in electrical systems by providing a safe path for electrical currents to dissipate into the ground. They are essential for residential, commercial, and industrial grounding systems. Proper maintenance of ground rods is crucial to ensure their long-term performance and safety. 
This blog will discuss essential tips for maintaining ground rods, including copper-clad ground rods, ground rod clamps, connectors, and their impact on performance and cost.
Choose Copper-Clad Ground Rods for Enhanced Performance: Copper-clad ground rods are popular due to their superior conductivity and corrosion resistance. The copper coating ensures excellent electrical conductivity, allowing for efficient dissipation of electrical currents into the ground. Furthermore, the copper cladding protects the rod from corrosion, ensuring long-term performance and durability. While copper-clad ground rods may have a slightly higher initial cost than traditional steel rods, their enhanced performance justifies the investment.
Ensure Proper Installation of Ground Rods: Proper installation is crucial for the effective functioning of ground rods. When installing a ground rod, ensure it is driven deep enough into the ground to reach the moisture level, which improves conductivity. You must install the rod vertically and securely to provide a stable connection. It is also essential to protect the exposed portion of the ground rod from physical damage or corrosion by using protective caps or covers.
Regularly Inspect and Maintain Ground Rods: Periodic inspections are essential to identify any signs of damage or degradation in ground rods. Inspect the rod for any physical damage, corrosion, or loose connections. If deterioration is detected, it is essential to remove the corroded portion or replace the rod entirely, depending on the extent of the damage. Regular maintenance and upkeep of ground rods will ensure their continued performance and reliability.
Use High-Quality Ground Rod Clamps and Connectors: Ground rod clamps and connectors are critical components that provide a secure connection between the ground rod and the grounding conductor. High-quality clamps and connectors ensure proper electrical contact, reducing resistance and improving conductivity. Use clamps and connectors of durable materials such as copper or bronze, as they offer better corrosion resistance and long-term reliability.
Consider the Price and Value: When selecting ground rods and related components, it is essential to consider both price and value. While cost may be a factor, it is crucial to prioritize quality and long-term performance. Investing in high-quality ground rods, clamps, and connectors may initially incur a higher cost. Still, minimizing maintenance, replacement, and potential safety risks associated with substandard components can save you money in the long run.
Follow Electrical Codes and Standards: Adhering to electrical codes and standards is vital for safely and effectively maintaining ground rods. Local electrical codes provide guidelines on installation practices, grounding requirements, and using specific materials. It is essential to familiarize yourself with these regulations and ensure compliance to maintain a safe electrical system.
Summing Up
In conclusion, proper maintenance of ground rods is essential for their long-term performance and safety. Choosing copper-clad ground rods, ensuring proper installation, regular inspections and maintenance, using high-quality clamps and connectors, considering the price and value, and following electrical codes and standards are critical practices for maintaining ground rods. 
By implementing these tips, you can ensure a reliable and safe grounding system, contributing to your electrical system's overall efficiency and safety.

Lightning Protection System Design and Products
The first step in lightning protection system design is Risk Assessment. Axis has used the guidelines of IEC 62305 Part 2 to design a Risk Assessment Software that allows you to assess the risks and determine the Class of Lightning Protection System (LPS) for your structure. This software uses parameters unique to your structure to help you determine the best and most efficient protection system. In fact, our software also allows you to calculate the Seperation Distance for your Lightning Arresters, Length of Earth Rods, Type of SPD, and more! Contact us to get access to our Lightning Protection System Design Software.
Based on your Risk Assessment, you can now design the external and internal protection systems for your building. The External protection system would include an Air Termination, Down Conductor and an Earth Termination System. For internal protection, one would use surge protection devices and equipotential bonding.
Air Termination
The positions of the Air Termination can be decided based on the rolling sphere method, the protective angle method and the mesh method. The rolling sphere method can even be used to define the zones of protection for structures with complex geometry. The radius for the sphere is determined directly from the Class of LPS.
The Protective Angle method is used for simple structures but only up to a certain height as determined by the class of LPS.
The Mesh Method is best used for flat surfaces where the air termination conductors are to be placed at the roof edges and where no other metallic structure will be above the air termination system.
Axis Air Termination Rods, made from high grade electrolytic Copper, provide the highest conductivity that allows the flow of lightning strikes without any damage to the structure or equipment.
Early Streamer Emission (ESE) Lightning Arrester
The ESE Lightning Arrester, also known as Active Lightning Arrester, provide an enhanced Radius of Protection, reducing the number of Lightning Arresters and down conductors needed for your building or solar project while still providing complete protection.
Down Conductors
Down conductors, connected to the Air termination system with suitable Axis products, should take the most direct route down the structure, with spacing between each one defined by the Class of LPS.Axis Copper Clad Steel Down Conductors are specially developed to offer the high mechanical strength of steel and the current carrying capacity of Copper.Since IEC 62305 also allows the use of rebars inside concrete structures as down conductors under certain conditions, Axis offers specially designed products to use this technology effectively.
Earth Termination
An Earth Electrode should provide low electrical resistance with the earth to allow for the dissipation of currents. It should also be resistant to corrosion because it will be buried underground for a long period of time.
Worldwide, one of the most popular Earth Electrodes are copper bonded earth rods, which comply with IEC 62561 Part 2. Since electricity is a surface phenomenon, the copper layer allows for a conductive path while the inner core of high strength steel provides the strength required for driving the rod inside the ground. Axis Copper Bonded Earth Rods have been are approved by Utilities across the world and continue to be popular due to their consistently high quality.
Internal LPS
The two major components of internal LPS are Equipotential bonding and surge protection devices (SPD’s). The purpose of Equipotential Bonding equipment is to bring all the metallic parts and equipment in a structure to the same Voltage Potential, to avoid hazards to human life or other damage. SPD’s protect electronic devices by breaking the circuit in case of an equipment or system fault.
Conclusion
Since 1994, Axis has continued to manufacture and supply high quality lightning protection and earthing equipment internationally. We have a proven track record of high quality protection. Our customers include Utilities, Government Organizations and Private Projects across the globe. To learn more about the Axis range of Earthing/Grounding Solutions and Lightning Protection, you can download our catalogue.

CCS Round Wire
0.8 Series CCS Round Wire
Origin of new material development
0.8mm series copper-clad ccs wire is a new type of material developed by our Company to replace pure copper. Because it has the advantages of high strength, low price, high corrosion resistance and high conductivity of copper, and meanwhile its comprehensive performance is high and its cost is more economical than pure copper grounding device, it has been widely used in UHV lines, petrochemical industry, nuclear power and high-speed railway, especially in key projects in recent years.
Tumblr media
Copper-clad steel:
The material in which the surface of a steel core is uniformly coated with copper includes copper-clad steel bars (for vertical grounding electrode only), copper-clad steel tape, and copper-clad steel wires (including round wires and stranded wires). According to the production process, it can be divided into continuous casting copper-clad steel and electroplating copper-clad steel.
Comparison between copper-clad steel grounding and traditional hot-dip galvanized steel grounding device
1. Corrosion rate comparision
Annual corrosion rate of grounding materials in some place of Beijing and Tianjin
The test results show that galvanized steel has the most serious corrosion and its corrosion rate is more than 50 times higher than that of pure copper; the corrosion degree of stainless steel is much lower than that of pure copper and copper-clad steel, showing good corrosion resistance; as a copper-steel composite material, the self-corrosion potential of copper-clad steel in soil is basically the same as that of pure copper, and its corrosion rate is the same as that of pure copper; the corrosion rate of the electroplated copper-clad steel with thinner coating is higher than that of the continuous casting copper-clad steel with thicker coating.
 2. Analysis and comparison of physical performance in short circuit
If the conductivity of copper were 100% and the conductivity of standard 1020 steel were only 10.8%, the conductivity of copper would be about 10 times that of steel. However, the conductivity of the 30% conductivity copper-clad round wire would be 30%, and the conductivity of the 40% conductivity copper-clad round wire would be 40%, which would be far better than the steel grounding body. Especially under skin effect, the conductivity of copper-plated strands at high frequencies would be much better than that of steel, that is, the conductivity of copper grounding body would be better than that of steel grounding body. The melting point of copper is 1083℃ and the maximum allowable temperature during short circuit is 450℃ ; the melting point of steel is 1510℃ and the maximum allowable temperature during short circuit is 400℃. Therefore, when the grounding body has the same cross section, the copper-clad steel grounding material has better thermal stability.
 3. Economic comparison
According to Appendix D of Technical Conditions for copper clad steel ground rod for Grounding in Electrical Engineering, the corrosion rates of copper clad steel in different soils are calculated according to the reference values in table. Corrosion rate of pure copper under different soil corrosion grades (mm/a)

Sotkl ��� Sino Ocean Taikoo Li in Chengdu
3 Aug 2020
Sotkl – Sino Ocean Taikoo Li
Design: Elena Galli Giallini Ltd
Location: Chengdu, China
Sotkl – Sino Ocean Taikoo Li Chengdu is a lower ground Shopping arcade forming part of a mixed-use development which includes a luxury boutique hotel and Grade A office uses. It sits in a prime location in the city centre of Chengdu, the capital of Sichuan province located in southwest China. Chengdu is now a burgeoning second tier city, renowned for its social, leisurely lifestyle and tea houses. The development is becoming the centre of Chengdu’s major shopping and cultural district, a place imbued in tradition and history. Directly connecting to Chunxi Road metro station, it links with the popular Chunxi Road area in Jinjiang District.
“The brief of this retail project required an innovative approach that could set this shopping mall apart from conventional images and formulas. We started from the consideration that modern shopping malls need to change the role they perform in peoples’ lives, becoming hubs for urban lifestyle that includes work, play, eat and shop. Our scheme exemplifies this new approach, introducing novelty in design and strong individuality”.
The retail complex is spread over three floors above ground and a basement shopping mall-arcade; it features a low rise, open air plan and lane-driven scheme defined by outdoor shopping mixed carefully with dining, drinking, entertainment and live performances. The site features traditional courtyards and buildings throughout with the Buddhist DACI TEMPLE, first built in 618AD as the composition focus.
Around, heritage led architecture embraces the traditional Sichuan style with modern interpretation. Visitors mingling and gathering amidst lanes, courtyards and plazas can enjoy unique experiences. The client brief aimed to define an interior design for the lower ground arcade (GFA 18,000sqm) which would complement the development and its uniquely distinct site, whilst providing a strong interrelationship with the upper retail complex.
Juxtapositions of old and new, heritage and nature, place and history were the essential themes for this project. The design created an environment which relates precisely to the place’ history and culture, its local spirit (its “Genius Loci”), avoiding the trap of making an indistinct shopping mall. It finds a language which defines its character amongst the repurposed, traditional architecture above. The lower arcade layout privileges interconnectedness, linking key areas above whilst working as a functional network below. It forms a loop of public space flanked by high street retail. Significant elements anchor the corners cinema, supermarket, bookshop and a Metro station.
The design aimed to generate dynamism and distinction, while maintaining an atmosphere of coherency and serenity. A vibrant environment, attractive visual elements and multiple amenities are key to providing leisure and entertainment for compelling experiences for the customers. Materials, colours and lights enhance quality through subtle elegance, defining the mall identity. Spatial layout and features emphasize naturalness with sophistication.
“Our project refers to the underground world of the Chinese landscape, rocks symbolism and “caves” imagery with their complex system of “worlds within worlds”, underground streams, lakes and “skylights” as reference for the compositions. Caves are containers for mystery and are believed to be places of special purified “QI”. Our design aimed to evoke that special kind of energy with its mysterious qualities”. A subterranean stream, the arcade loop flows with a fluid, seamless design eroding the clusters of shops. The ambiance exhibits warmth and a tranquil quality encouraging inhabitation. The ceiling is a key element characterized by rhythmically distributed fissures and holes that incorporate lighting and signage systems. Strategical skylights lined with copper mesh and theatrically lit act as focal points and facilitate navigation. The arcade has a counterpoint in the dramatic, sculptural design of functionally specific areas that generate memorable unique spaces, immediately recognizable.
The Metro entrance, the main access for people arriving by public transport, is a modern gateway. Envisaged as massive cave with angled stone walls and light penetrating from the plaza above, the Entrance hall leads to the core of the arcade loop through a digital corridor, a place unfolding like a traditional folded scroll for visual, digital art and exhibitions.
As metaphorical, massive caves, escalator lobbies display organic forms and striking proportions. Lobbies allow vertical circulation and invite people to linger. They open up toward the arcade, eliciting a feeling of expansion and openness. Inside, carefully defined geometry of stone-clad walls display a variety of man-made “rock” formations in granite and lava-stone rods with a variety of surface finishes. This system of bespoke prefabricated panels, factory –made and mounted on site achieved accuracy and cost control whilst the stone palette relates to the local materials of surrounding heritage buildings.
Sculptural frames in GRC, encased within illuminated back drops of glass rods and copper, showcase the advertisement panels as jewellery boxes.
Throughout the scheme, natural materials, stone, meshes and metals combinations with different colours, textures and finishes, blend in harmonious interplay.
Delicately detailed metalwork highlights the key features with a mix of grey steel and naturally burnished copper. A split rectangle forms the door handles, the inclined glass balustrade held with brackets crafted from solid metal, hanging shop signage, all are balancing the boldness of the scheme with clear-cut detailing. Strong shapes generate eye-catching points and visual interest.
The washrooms display a dynamism complementing the liveliness and sculptural qualities of the overall design. While fulfilling functionality and user-friendliness, the design focuses on attractiveness and novelty, encompassing a playful dimension. Vigorous shapes hewn in a white and dark grey solid surface material and unconventional lighting set them apart from the typical washroom ambiance. A collection of freestanding sinks are clustered beneath mirror units suspended from the ceiling, folded planes line up to form cubicles, urinals purposely disguise their function with angled, multifaceted partitions, other standard units provide function variety, seating, makeup counters or baby change areas, through subtle diversification.
The designers focused on creating a World-Class environment that would attract and retain consumers, and the leasing team set ambitious targets for brands that are not yet in Chengdu.
The development is becoming Chengdu’s new lifestyle epicentre contributing to its growth. Chengdu was listed by Forbes Magazine in 2010 as one of the fastest growing cities in the world.

Super Power Earthing /Chemical Earthing Electrode
Super power Earthing presents, Lightning Protection System with one        stage ahead innovation which is an entire answer for all the physical harm due lightning flashes to a structure. Our Conventional Lighting Protection framework includes both outer and inward lightning assurance framework. Essentially, our regular lightning insurance framework does keep lightning from striking; as well as gives a way to controlling it. earth electrode ,     earthing electrode price  , copper earthing electrode  ,earth ground rod ,earth resistance tester ,  earth meter
From the season of the main establishment of lightning insurance frameworks to the present day, portrayal of the adequacy remains a repeating question, to illuminate this inquiry we in Super Power Earthing have presented another innovation in Lightning Arrester named: Conventional Lightning Arrester. As indicated by the laws of material science, at whatever point a thunder strike best of the building or structure an occasion of undesirable current passes however the structure; here to keep the structure our Conventional Lightning Arrester which is mounted on the highest point of building; electrically interface itself to the ground through a wire or earthing copper strips, to shield the working from the occasion of lightning strike. This Lightning Arrester releases the strike without passing and harming non-directing parts of a structure, for example, those made of wood, block, tile or cement. Our customary lightning assurance framework, includes parts like conductors, air terminals, air terminal bases, establishing items, clasp and equipment and Connectors and fittings. With its extraordinary highlights of Low Cost, uncommon electrical dissemination qualities, withstanding power in fast breezes and replaceable scattering tips; ordinary lightning arrester has been acknowledged , perceived and confined around the world.
Real Components engaged with Conventional Lightening Systems:
Air Terminal Network - This terminal system accessible in GI, Copper or Al fundamentally catches the lightning strike to an engaged point so as to guarantee that the release current can be securely guided by means of the down channels to the devoted earthing framework.
Down Conductors – The capacity of down conduit accessible in GI, Al, or Copper where the most favored is Copper Clad Steel Conductor, is to give a low impedance way from the air end to the earthing framework so the lightning current can be securely led and disseminated to earth without the advancement of unnecessarily expansive voltages.
Earthing System - In Lightning discharge,a compound earthing framework characterizes the electrical capability of the transmitters in respect to that of the Earth's conductive surface. Lightning security frameworks has an extraordinary establishing frameworks intended to securely direct the to a great degree high voltage streams related with lightning strikes and in this way limiting the earth voltage potential ascent.
