Heat Shrinkable Right Angle and Straight boots

Heat Shrinkable Right Angle and Straight boots

Product Code: CHRB/CHSB

Used to insulate the bushings in the Cable termination box, where the clearance between phase to phase and phase to earth is less than the normal air clearance. These boots provides protection against flashover in the event of high humidity, rodent menace and surge impulse in switchgears and transformers.

Material: High quality Cross linked non tracking Polyolefin weather resistant material.

Standard Color: Red
