Overhead Line Tube (Insulcover)

Overhead Line Tube is a Medium Voltage Line Cover that provides insulation for overhead conductors to help prevent electrical outages caused by trees or wildlife coming into the contact with distribution lines. It is manufactured from high quality Non Tracking Polyolefin material.

FEATURES & BENEFITS:

High Di-electric strength
Excellent UV stabilized & Weather resistant
Tracking & Erosion resistant
Prevent Conductor from Chemical corrosion effected by strong acid, alkali, salt, etc.
Halogen free
Flame Retardant
