66kV Polymer Suspension Insulator

Insulators play two basic roles in overhead transmission lines, namely, to support wires and prevent current from returning to the ground. These two roles must be guaranteed. Insulators shall not change due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the service life and operating life of the whole line will be damaged.
