1. Overview

G10 epoxy glass fiber laminate is a high-strength, high-insulation composite material made from glass fiber cloth impregnated with epoxy resin.In high-voltage power distribution systems, it is widely used to manufacture busbar supports, insulation brackets, and mounting structures that ensure electrical safety and mechanical stability.

2. Role in High-Voltage Busbar Systems

In a high-voltage cabinet or transformer, busbars carry large current loads and require reliable insulation and structural support.G10 provides both electrical insulation and mechanical strength to safely separate and fix copper or aluminum busbars.

Main functions:

Provides high dielectric strength to prevent phase-to-phase and phase-to-ground short circuits.

Offers excellent mechanical rigidity, capable of withstanding electromagnetic forces during current surges or short circuits.

Ensures dimensional stability and creep resistance under long-term thermal and electrical stress.

Resists moisture, oil, and aging, suitable for both indoor and outdoor environments.

3. Advantages of Using G10 for Busbar Supports

4. Typical Applications

High- and low-voltage switchgear busbar supports

Transformer and reactor connection insulation brackets

Power distribution cabinet mounting plates

Busbar insulating spacers and separators

5. Summary

G10 epoxy glass fiber laminate is an ideal insulation and structural material for high-voltage busbar systems.
It combines electrical reliability, mechanical strength, and long-term stability, ensuring the safe and efficient operation of modern power equipment and new energy systems.
