Heat Shrinkable Moulded Shapes 
Right Angle Boot/Straight Boot - ANGLEBOOT
Angleboots are Heat Shrink Right Angle / Straight Boots provide insulation to the bushings in the cable termination box, where the clearance between phase to phase and phase to earth is less then the normal air clearance. These boots provide protection against flashover in the event of high humidity, rodent menace and surge impulse.
The boots are mode from high quality cross linked non tracking polyolefin material. They are internally coated with water resistant red mastic.
