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