Polymer Insulator

Composite polymer insulators are made from multiple materials, primarily consisting of a fiberglass core rod, a silicone rubber jacket, and metal connectors at both ends. Widely used in high-voltage transmission lines, especially in polluted or harsh environments and applications requiring high mechanical strength.

Main Features
• Lightweight: Lighter than glass or porcelain, polymer insulators are easier to install and ideal for long-distance, high-voltage lines.
• Pollution Resistant: The hydrophobic silicone rubber jacket reduces flashover in humid or polluted conditions.
• Impact Resistant: Strong impact and bending resistance, suitable for earthquake-prone or harsh environments.
• Shatterproof: Highly break-resistant, lowering the risk of power outages due to damage.
