Composite Cross Arm Insulator
Picture:
Named:
Composite cross arm insulator also called polymer cross arm insulator, silicone rubber cross arm insulator. This type polymer insulators can replace traditional wooden cross arm or steel cross arm.
Structure:
- • Silicone rubber shed
- • Silicone rubber housing
- • Fiberglass core rod
- • End fittings
Advantage:
- • Decrease single phase to the ground fault rate
- • Increase its life span
- • Reduces weight because of replace steel cross arm
- • Increase the mechanical strength
- • Increase corrosion resistance
Parameters:
