Overhead Line Cover - Silicone

Overhead Line Cover - Silicone - Self-locking

Gala Silicon Overhead Line Covers are made from high quality non-tracking silicon rubber that are designed for field installation over bare conductors. These covers provide a layer of electrical insulation for Phase-to-Phase and Phase-to-Ground protection from bird and animals. The GSOC provides electrical insulation, UV resistance and tracking resistance. Silicon Self-fusing Tape can be applied on it for better insulation.

Features & Benefits :

Excellent UV and Ozone resistance.
Excellent Tracking resistance.
Good Di-electric strength.
Protection for leads and jumpers.
Highly flexible silicone tubing makes application easy.
Flame Retardant.
No special installation tool required.
Does not require further derating conductors.
Helps prevent contacts by eliminating gaps in coverage.
Provides Insulation Enhancement upto 765 kV

GSOC-M for voltage level upto 12 kV
GSOC-H for voltage level upto 36 kV
GSOC-EH for voltage level upto 765 kV
