Composite Deadend Insulator
Picture:
Named:
Composite deadend insulator also called composite dead-end insulator, polymer deadend insulator, polymer dead-end insulator, silicone rubber deadend insulator, silicone rubber dead-end insulator. Composite deadend insulators is a main type polymer insulator and was widely used on tension tower or angle tower.
Structure:
- • Silicone rubber shed
- • Silicone rubber housing
- • Fiberglass core rod
- • End fittings
Advantages of polymer deadend insulator :
- • Excellent hydrophobicity
- • ECR fiber glass core
- • HTV silicone rubber
- • Forged end fitting
- • UV ray resistance
