Description
33kV dead end insulators play two fundamental roles in overhead transmission lines, one is supporting wires, and the other one is preventing current from returning to the ground. These two roles must be guaranteed, dead-end suspension insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions.

Application
Polymer dead end insulators are widely used in transmission lines, substations, power equipment and other fields. In transmission lines, composite rod-shaped suspension insulators can be used in power towers, cable suspension wires and other locations to support wires and insulate. In substations and power equipment, composite rod suspension insulators can be used on equipment such as isolation switches, circuit breakers, and cable terminals to ensure the safe operation of equipment.
