The High Voltage Post Polymer Insulator is a key insulation component widely used in high-voltage power transmission and substations. It functions as a structural support for conductors while preventing current leakage and grounding. Compared to traditional porcelain insulators, polymer insulators offer superior contamination resistance, lightweight structure, and high mechanical strength, making them ideal for modern power grid applications.
This insulator consists of a high-strength fiberglass reinforced plastic (FRP) rod core covered with high-grade silicone rubber sheds. The metal end fittings are crimped using hot-dip galvanized steel or aluminum alloy. The overall structure is compact, well-sealed, moisture-resistant, and highly durable in outdoor environments.
