Particularly useful in confined spaces, our Raychem BPTM Busbar Heat Shrink Tubing can be used on both circular and rectangular copper or aluminium busbars. When heat is applied, the tubing shrinks snugly over the busbar profile ensuring that the required minimum wall thickness is obtained. The Busbar Heat Shrink Tubing can be installed easily during large-scale production using an oven, or in the field using a gas torch or hot air.

The Busbar Heat Shrink Tubing is manufactured from a non-halogen based polymer which has a high performance in high voltage environments and greatly reduces the noxious and corrosive effects in fire situations.

The use of this 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. The Busbar Tubing provides flashover protection up to 25kV.
