66kV 160kN Polymeric Insulator with Eye
What Makes Up a Polymer Insulator?
1. Core Rod – Strength & Support
At the center is a high-strength fiberglass rod. This part does the heavy lifting - it holds the load and keeps the electricity in check.
2. Outer Layer – Weather Protection
The housing, made from silicone rubber, shields the core from rain, UV rays, and pollution. It includes both the sheath and the sheds that help prevent current leakage.
3. Metal End Fittings – Secure Connections
Fitted at both ends, these steel or ductile iron parts connect the insulator to the power system - one side to the tower, the other to the line. They're key to ensuring safe and stable mechanical support.
