Polymer suspension insulators

Polymer Suspension insulators

Polymer Suspension insulators ,also called Strain insulators, are used for the rated voltage of 35~500kV AC power system in common and dirty areas, overhead lines and substations with a frequency not exceeding 100Hz for drape and tensile strength.

Polymer suspension insulators

The ambient temperature of the insulator installation site is between -40 °C and +40 °C, and the altitude is not more than 1000 m.
Suspension polymer insulators are widely used in the insulation and mechanical fixing of high-voltage overhead transmission lines and soft and bushings of power transmission and distribution. In the suspension insulator, it can be further divided into a polymer suspension insulator and a rod-shaped suspension insulator.
