Heat
Shrinkable Anti Tracking Tubings are manufactured from cross
linked polyolefin material that offers exceptional insulation
and long term service reliability. Due to its excellent non-tracking
and erosion resistance inbuilt character these tubings find
proven applications in electrical and electronic segment of
industries. The following are few typical applications where
these sleeves are used
- As an intergral part of Heat Shrinkable power cable terminations
upto 36 KV voltage class for indoor and outdoor applications.
- As an integral part of Heat Shrinkable straight through
joints upto 36 KV voltage class in combination with other
electrical supporting device.
- For providing bus bar insulation on straight and bent
electrical bus bar.
