Polyolefin Overhead Line Cover (Insulcover)

Insulcover is a Wrap Around Line Cover that provides retroﬁt 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 Cross-linked Polyoleﬁn material. Gala Overhead Line Covers can be used in many applications to enhance the insulation up to 400 kV. Insulcover is designed to insulate existing bare lines without costly conductor replacement expenditure or additional line hardware.
Installation is easy by using the Split Insulation Tube Tool which remains stationery at single location.

FEATURES & BENEFITS:

High Di-electric strength
Excellent UV stabilized & weather resistant
Passed 5000 Hrs. UV test
Tracking & Erosion resistant
Prevent Conductor from Chemical corrosion effected by strong acid, alkali, salt etc.
Halogen free, Flame retardant
Insulcover is available in ﬁve sizes that covers conductors up to 800 sq. mm.
