Ground Module

BEST Grounding Module

Performance and characteristics of BEST grounding module:

The low-resistance grounding module is a non-metallic material-based grounding body composed of non-metallic minerals with good conductivity and chemical stability, metal ground rods, electrolytes and humectants.

 Ground Module performance and characteristics

1. The contact resistance is greatly reduced.

The main material of the grounding module is similar to the physical structure of the soil, and can be integrated with the soil, so that the effective contact area between the grounding body and the soil is increased by many times compared with that between the traditional metal grounding body and soil, which has increased the flow area of the grounding body itself and greatly reduced contact resistance of the grounding body to the soil.

 2. The grounding resistance is stable

The grounding module has strong moisture absorption and moisturizing ability, ensuring that the grounding module can effectively play the conductive function. At the same time, the conductive characteristics of the grounding body are not affected by the weather changes such as dry humidity, high and low humidity. Therefore, it can provide a stable low grounding resistance.

Ground Module

3. Reduce ground potential counterattack

The non-metallic material in the grounding module forms a low-resistance region with a gentle change between the metal and the soil with a large difference in electrical resistivity. When encountering a large current surge, the potential gradient of the grounding body and the grounding wire can be lowered to lower the step voltage and the contact voltage so as to reduce the probability of counterattack of the ground potential.

 4. Long service life

The main material of the grounding module is similar to the physical structure of the soil, and can be integrated with the soil, so that the effective contact area between the grounding body and the soil is increased by many times compared with that between the traditional metal grounding body and soil, which has increased the flow area of the grounding body itself and greatly reduced contact resistance of the grounding body to the soil.

 5. Simple construction and installation

Compared with the traditional metal grounding device, the construction work is greatly reduced.

 Ground module use range:

1. Working grounding, safe grounding and lightning protection for power plants, substations, switching stations, high-voltage transmission lines, electrified railways, telecommunications, mobile communication base stations, microwave relay stations, ground satellite receiving stations and radar stations;

2. Working grounding and protective grounding for valuable precision instruments, computer room equipment, postal and telecommunications program control equipment, radio and television equipment, and electronic medical equipment;

3. Lightning protection of various high-rise buildings, tall structures, scenic ancient buildings and tall memorial towers;

4. Lightning protection of oil pipelines, oil and gas tanks, and inflammable and explosive material warehouses.

 Ground Module usage method:

1. The low-resistance grounding module can be vertically embedded or horizontally embedded, and the  embedded depth should not be less than 0.6 m, generally 0.8- 1.0 m.

2. When several modules are embedded in parallel, the module spacing should not be less than 4.0 meters. If the conditions are not allowed, it can be appropriately reduced. At the same time, the value of the module utilization coefficient should be reduced when the amount of module is calculated.

3. When the module pole cores are connected in parallel or connected to the ground wire, they must be welded, with the welding length no less than 100mm.

4. The welding slag should be removed at the weld, coated with anti-corrosive conductive paint or wrapped with HD-JZ high-efficiency swelling resistance-reducing agent.

5. During backfilling, it should be sprinkled with water in an appropriate amount, tamped in layers and watered again after backfilling. Meanwhile, the grounding resistance should be measured after the module is fully hygroscopically absorbed (72 hours).

2. Existing soil

3. Special filler

4. Ions diffuse around

5. Expand the conductive range of the soil

 The chemial grounding electrode system consists of advanced alloy compounds, with a copper tube on the outside to ensure maximum conductivity and long service life. The filling material inside the conductor contains special ionic compounds, which can absorb moisture in the air adequately. Active ions can be effectively released into the soil through the deliquescence, and interact with the moisture in the soil and air to further promote the external slow release and drag reduction of conductors, and to maintain the long-term stability of the resistance value. Compounds in conductors are gradually combined in colloidal transparency over time.

Because of its multi-stranded properties, the electrical conductivity and tensile strength are relatively good, and the product can be customized to enhance the elongation rate by multiple heat treatment in the production process, which has increased the strength and toughness of the steel compared with the pure copper strand. Moreover, the good electrical conductivity and corrosion resistance of the copper material are maintained due to the principle of the skin effect. Therefore, it is very popular in many fields of lightning protection and grounding, especially in power plants, substations, high-speed rail, subways, electrified railways, large-scale chemical plants, mechanical plants, communication base stations, transportation, computer rooms, highways and military bases.

 Copper Clad Steel Stranded Wire Characteristics

CCS Round Wire

0.8 Series CCS Round Wire

Origin of new material development

0.8mm series copper-clad round 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.

 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.

CCS Round Wire

Development of copper-clad steel grounding device

With the increasing voltage level of power lines and the increasing capacity of the system, higher requirements are put forward for the safety and reliability of grounding devices.

 The traditional method in foreign countries is to use pure copper as the grounding material, but pure copper is expensive and it is a strategic resource, which is not suitable for being massively used as grounding devices in China. From 1910 to 1955, National Bureau of Standards (NBS) conducted corrosion resistance studies of grounding bodies. 36,500 samples collected at 128 test sites throughout the United States represented 333 metal materials consisting of iron, non-ferrous metals and protective coatings, respectively. The test results show that only steel bars and stainless steel bars with copper plating thickness over 0.5mm can be accepted.

 In addition, continue the statistical data of 8 to 30 years and take the test results of 43 copper samples in different soils, 41 of which were calculated, to get the 0.17mm average pitting depth of 30 years. Therefore, some international standards have determined the thickness of copper coating of copper-clad steel material to be at least 0.25 mm. Considering the hard friction during construction, it is suggested that the thickness of copper coating be defined as 0.5-0.8 mm.

 In China, copper clad(copperweld) steel materials are widely used in substation grounding grids in areas with high soil resistivity. Because of the characteristics of UHV project, such as high voltage level, large capacity and short power cut window period, combined with the corrosion intensity of groundwater in the area, copper-clad steel grounding devices have been applied in UHV lines and many UHV lines in China use copper-clad steel materials as grounding bodies.

CCS Flat Bar

opper-clad Flat Steel

The most superior performance of copper-clad flat steel is the increased grounding surface area, which has improved the electrical conductivity of the horizontal grounding body, thus saving grounding materials.

 CCS Flat Bar-6 Meter Production Process

Copper-clad flat steel is produced by electroplating process, which realizes the high combination of copper and steel, that is, the 99.99% electrolytic copper molecule is uniformly plated on the surface of the steel core.

 CCS Flat Bar-6 Meter Corrosion Resistance

The copper-clad flat steel has excellent anti-corrosion performance. Since the surface of the steel core is uniformly covered by copper and the copper layer is thick, it can be produced according to customers' requirements with the service life more than 20 years.

 CCS Flat Bar-6 Meter Better Conductivity

The most superior performance of copper-clad flat steel as the grounding wire is due to the large grounding area of the copper-plated flat steel. Therefore, it has better electrical conductivity and its own resistance is much lower than that of conventional materials.

 CCS Flat Bar

CCS Flat Bar-6 Meter Wider Range of Application

Copper-clad copperweld flat steel can be used as lightning strip, up lead or down lead, and horizontal grounding wire, which is suitable for soil conditions with different humidity, temperature and PH.

 Safe and fast installation

During the construction of copper-clad copperweld flat steel, it is recommended to use hot-melt flux produced by beisuda company to connect, because the permanent joint connection is more firm and the installation is convenient, which has greatly improved the construction efficiency.

 Cost Reduction

Because of its relatively wide characteristics, copper-clad copperweld flat steel is used as grounding conductor and since its grounding contact area is large, the conductivity has been effectively enhanced, thus greatly reducing the cost of grounding compared with the traditional pure copper material.

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.

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)
