Composite Suspension insulator also called composite Strain insulator, are used for the rated voltage of 10kv~500kV AC power system in common and dirty areas, overhead transmission and distribution lines and substations with a frequency not exceeding 100Hz for drape and tensile strength.
The ambient temperature of the Suspension insulators installation site is between -40 °C and +40 °C, and the altitude is not more than 1000 m.
polymer Suspension 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 insulators and a rod-shaped suspension insulators.
