Description

Technical Field

[0001] This utility model relates to the field of power technology, and in particular to an insulated switch rod for power operation. Background Technology

[0002] Insulated operating levers are mainly used for operating high-voltage electrical equipment, such as circuit breakers and disconnectors. They possess excellent insulation properties, ensuring the safety of operators during live-line work.

[0003] Existing power operation insulating switch rods mainly consist of several parallel rubber rods and sealing rings. They do not consider that when the internal and external pressure differences are large during actual use, the device cannot effectively balance the internal and external air pressure differences, which may lead to water vapor seeping into the device and causing it to conduct electricity.
