Product Description

What is a glass disc insulator?

Compared to ceramic materials, glass disc insulators have high dielectric strength.

Glass disc insulators have high resistivity and a low coefficient of thermal expansion.

Compared to porcelain insulators, they have higher tensile strength.

Features of Glass Insulator

● Application: Suitable for transmission and distribution lines;

● Advantage: The surface of glass insulator has high mechanical strength, and the surface is not easy to crack and the aging speed is slow, no need to measure insulation resistance during operation, low operation and maintenance costs;

● Applicable Standard: IEC, GB, BS, ANSI, AS, or Customer's requirement;
