DESCRIPTION

Product Overview

A Support Insulator is a key component used to support conductive parts while providing insulation in high-voltage electrical systems.
Wishpower’s composite support insulators are made of silicone rubber sheds and high-strength FRP rods, delivering excellent electrical insulation and mechanical stability.
They are widely used in substations, switchgear, industrial systems and outdoor installations.

Product Features & Advantages

1. High Mechanical Strength

Reinforced ECR fiberglass rod with excellent bending and compressive resistance.

2. Superior Insulation Performance

Hydrophobic silicone rubber sheds reduce pollution flashover and provide stable insulation.

3. Weather & Corrosion Resistance

UV-resistant, salt-fog-resistant and suitable for harsh outdoor environments.

4. Lightweight Design

Lighter than porcelain insulators, easier installation and lower labor cost.

5. Long Service Life

Durable structure with very low maintenance.
