Busbar Insulation Tubing (BBIT) up to 36 kV – BBIT-100/40-A/U-4
TE Connectivity’s (TE) Raychem BBIT thick-wall, heat shrink tubing provides insulation enhancement and protection against flashover and accidentally induced discharge.
Particularly useful in confined spaces, TE’s Raychem BBIT 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. The BBIT tubing can be installed easily during large scale production using an oven or in the field using a gas torch or hot air. The BBIT tubing is manufactured from a halogen-free based polymer which has excellent performance in high voltage environments and reduces the noxious and corrosive effects in fire situations.
The use of the BBIT 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 BBIT tubing provides flashover protection up to 36 kV.
