Heat Shrinkable Busbar Tubing 

 

 

Description:

LR-BT Heat Shrinkable Busbar Tubings consist of a flame-resistant and environmental friendly polyolefin compound irradiated specially formulated.

They exhibit excellent electrical insulation, good flame resistant as well as high mechanical properties for the save operation of power system to provide strong protection.  They are extremely flexible, allowing them to be easily positioned on busbars and quickly installed using a gas torch or oven. They have a high shrink ratio, so each size of tubing fits a range of busbar sizes.

Application:

LR-BT Heat Shrinkable Busbar Tubings are widely used as protective insulation material for busbar in switchgear cabinet, transformer substation and distribution cabinet at operating temperature from -40 to 105.
