Description
220kV high outdoor insulator can work for service voltage 230kV. It can be equipped with corona rings (optional), to evenly distribute the high voltage around the insulator to ensure there is no potential difference between various parts of the ring, to achieve the effect of voltage equalization.

Application
Silicone rubber suspension 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.
