Product Description

 

The insulator is suitable for transmission and distribution lines. The surface of the glass insulator has high mechanical strength, the surface is not easy to crack, the aging speed is slow, the insulation resistance is not needed to be measured during operation, and the operation and maintenance cost is low.
Standards: IEC, GB, BS, ANSI, AS or as per requirement of customers.

Service Environment

1. Harsh weather conditions : The aerodynamic principle is taken into account in the shape design of the geotype glass insulator, which reduces the influence of wind load on the insulator in strong wind environment and improves the stability of the transmission line in harsh weather conditions. It is commonly used in areas with strong wind or power lines that cross rivers and straits and are prone to strong winds .

2. Dirty environment : Ground-line glass insulators perform well in dirty environments. Through the special structure or surface treatment of the umbrella skirt, the creepage distance is increased, and the insulation performance in dirty environment is improved. It is often used for power transmission lines in areas with serious industrial pollution and coastal salt spray areas.
