Particularly useful in confined spaces TE's Raychem BPTM can be used on both circular and rectangular copper or aluminium busbars. On application of heat, the tubing shrinks snugly over the busbar profile ensuring that the required minimum wall thickness is obtained. TE's Raychem BPTM tubing can be installed easily during large scale production using an oven or in the field using a gas torch or hot air.

Our busbar insulation tubing is manufactured from a non-halogen based polymer which has excellent performance in high voltage environments and greatly reduces the noxious and corrosive effects in fire situations.

The use of TE’s Raychem BPTM tubing allows equipment designers the freedom to reduce air spacing between bus bars, such as in the manufacture of switchgear cabinets where space is at a premium. TE’s Raychem BPTM tubing provides flashover protection up to 25 kV.
