Copper & Aluminium Insulated Busbars

Product Features New designs of switchgear for voltages upto 36kV follow the principles of reducing size as much as possible. Insulated busbars provide maximum protection, particularly in confined spaces, against flashover and accidentally induced discharge. Choosing the right busbar insulation can be difficult. Many conventional insulating materials require heavy investment in tooling and do not meet manufacturers’ requirements for performance and reliability. To solve this problem, Raychem RPG has developed a series of heat-shrinkable tubings for use on both aluminium and copper insulated busbars of circular or rectangular cross-section. These busbar insulation tubings are currently used in switchgear cabinets throughout the world.

Flashover Protection  The insulation tubings provide excellent protection against flashover and accidental bridging, in indoors and outdoors applications. They are ideal for protection against bird and animal-induced outages. Non-Halogen Based Material Manufactured from a radiation crosslinked highly modified ethylene-propylene polymer, the insulation tubing will not drip or flow at elevated temperatures and offers exceptional insulation and long term reliability even at continuous high operating temperatures. The non-halogen material base greatly reduces noxious and corrosive effects in a fire situation. High Voltage Performance A proprietary additive technology gives the insulation tubing outstanding resistance to both corona attack and the surface tracking which can occur in an aggressive HV environment. Thermal Rating Busbars covered with insulation tubings dissipate heat better than bare copper or aluminium busbars, therefore no reduction in current rating is necessary. Continuous operating temperature upto 105 Deg.C

Raychem RPG now offers a extended range of Copper/Aluminium components for applications in switchboards and allied equipment.

The offerings includes

– Copper/Aluminium Rectangular Bare & Sleeved Busbars. 

– Copper/Aluminium Round Busbars. 

– Copper/Aluminium Hollow sections of various sizes and shapes. 

– Jaw/Cluster contact assemblies for Switchgears. 

– Other Copper/Aluminium components on request.

Advancing from Industry 4.0 to Industry 5.0

Industry 4.0

Unquestionably, one of the most significant industrial developments to have emerged in the previous decade is Industry 4.0. The German government’s high-tech strategy team first developed Industry 4.0 as a concept at the 2011 Hannover Fair using the terms “Internet of Things” and “Cyber Physical Systems.” Industry 4.0 is now acknowledged as a German idea that was embraced on a global scale over the previous decade. Similar strategic goals have been established by other industrialized nations, and significant research has gone into creating and deploying some of the industry 4.0 technologies. The nine key enabling technologies that Industry 4.0 considers to be its pillars are:

Internet of Things (IoT)

Big Data Analytics

Augmented reality

Simulation

Autonomous Robot

Horizontal and vertical integration

Cyber Security

Cloud Computing

Additive Manufacturing (AM)

Industry 5.0

Industry 5.0 highlights the need to place the wellbeing of industry employees at the core of the production process. By letting research and innovation drive the shift to a sustainable, human-centric, and resilient industry, Industry 5.0 complements the current Industry 4.0 paradigm. Human-centricity, sustainability, and resilience are the three interlinked key values that make up Industry 5.0. Six enabling technologies have been recognized as part of Industry 5.0.

Simulation and digital twins for system modelling.

Smart materials with embedded sensors and increased characteristics that are recyclable thanks to bio-inspired technologies.

Technologies for personalized human-machine interaction that connect and integrate the advantages of humans and machines.

Technologies for energy conservation, renewable energy, energy storage, and autonomy.

Artificial intelligence that can be used to act by identifying causalities in complex, dynamic systems.

Busbar for Electric Vehicles

Typically made from copper or aluminum, busbars are rigid and flat — wider than cables but up to 70 percent shorter in height. They can also carry more current than cables with the same cross-sectional area. These attributes make busbars ideal for some high-voltage connections in Electric Vehicles (EVs) and a key component of the electrical architectures of tomorrow’s vehicles.

Major driving factors of busbars in Electric Vehicle are:-

Lack of space within vehicles.

Need for automated assembly.

Busbars can carry more current because of their shape.

Raychem RPG Manufacturing, with multiple locations in India, is a leading supplier of Busbars to the Electric Vehicle industry. Our customized support also helps Raychem RPG’s automotive customers to meet tight deadlines and reduce costs. The company works side by side with design engineers to select the proper material, dimensions, tolerances, and optimal performance with the best cost solutions. Raychem RPG Busbar types include Copper, Aluminum solid & Flexible ( Solidified / Diffusion Bonded ), Surge protection, and Electrical panel Busbars.

Raychem RPG supports for tool development with its suppliers to produce customized busbar solutions that enable tight tolerance specifications for busbar performance and automatic assembly needs. Raychem RPG engineering enables a complex busbar design that requires multiple axes bending, forming, and twist profile that is needed for numerous continuous power connections required in today’s tight-spaced, high-performance engines. In addition, minimum or zero material waste can be achieved, reducing your product cost.

As power systems become faster and more complex, the challenges to efficiently integrate busbars in tight-spaced, Battery pack, Power Distribution System (PDU) or Battery Management Systems (BMS) have become increasingly relevant. These requirements are driving the need for greater flexibility for configuration and production of both large and small footprint busbar inter-connection. Raychem RPG produces Flexible, Multi-layered Busbar Assemblies meeting the exact requirements and challenges of today and tomorrow’s Electric Vehicles.
