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.

Raychem RPG has a World class manufacturing facility where highly skilled operators do the fabrication with the best equipment and tools.

The Insulation process is carried out under controlled temperature and air flow conditions, putting to use Raychem RPG's several years of experience with insulation enhancement systems
