Cross Arm Key Advantages
Composite insulator is its high hydrophobicity, which makes it highly resistant to pollution and pollution. This feature helps minimize surface leakage and improves overall performance in contaminated environments.
Materials & Product Structure
1. Epoxy Glass-Fiber Core Rod
A fiberglass rod made of high-strength epoxy resin is the main part of the insulator. As the core of the structure, this rod ensures dielectric insulation and supports mechanical loads.
2. Silicone Rubber Housing
High-grade silicone rubber that has been vulcanized at high temperatures and strengthened with compounds for flame resistance, anti-aging, and hydrophobic migration makes up the external housing.
- Increases creepage distance
- Defends the core from pollutants, rain, snow, and UV rays
- Offers extraordinary resistance to weathering, erosion, and tracking
3. End Fittings
Secure connections and long-term mechanical stability under both vertical and horizontal loads are guaranteed by precisely designed metallic end fittings.
