Electrical Busbars

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 busbars of circular and rectangular cross-section. These busbar insulation tubings are currently used in switchgear cabinets throughout the world.
