Heat Shrinkable Bus Bar Tube is specially made from crosslinked polyolefin that will shrink to fit any rectangular, square or round aluminum/copper bus bars. On applying heat the tubing shrinks neatly over the bus bar ensuring that the minimum thickness is obtained. It is widely used in confined places where spaces are scarce.

Description
Application
- CBT is widely used in switchgear equipments and confined spaces as it needs minimum bus bar clearance and protects against accidental flashover.
- It is suitable for both indoor and outdoor use as it does not get damaged by extreme weather or ultraviolet rays.
Features
- Tested as per IEC-60332-1-2-2004 & IEC 754 PART 1
- Requires Minimum Bus Bar Clearance
- Good Thermal Emissivity
- Continous Opeating Temprature:-30°C to 130°C
- Halogen Free
