Busbar Insulation: BBIT & BPTM
AT A GLANCE:
- Exceptional insulation and long term reliability even at high continuous operating temperatures
- Extremely durable, resists damage from solvents, ultraviolet light, weathering, mechanical impact and general wear and tear
- Indoor and outdoor use
- Excellent anti-tracking properties
- Can be stored indefinitely at temperatures up to 50°C without loss of performance
- REACH and RoHS compliant
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 non-halogen 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.
