Voltage Class 25 KV, Application ø 6.5-220 MM, BPTM-235/130-A/U-4
TE Connectivity’s (TE) Raychem BPTM medium-wall, heat shrink tubing provides insulation enhancement and protection against flashover and accidentally induced discharge.
Particularly useful in confined spaces, the BPTM tubing 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.
The BPTM tubing is manufactured from a halogen-free based polymer which has excellent performance in high voltage environments and greatly reduces the noxious and corrosive effects in fire situations.
Use of the BPTM tubing allows equipment designers the freedom to reduce air spacing between busbars, such as in the manufacture of switchgear cabinets where space is at a premium. The BPTM tubing provides flashover protection up to 25 kV.
