        1. We are specialty on epoxy resin medium voltage and high voltage components, such as 10KV, 24 KV and 40.5KV Circuit Breaker , Load breaker switch , Disconnecting Switch , Epoxy resin switchgear bushing , contactor box , insulators and transformer . 630A, 1250 A ,2500A , 3150A and 4000A contact box , club contact , fix contact, arm contact and jaw contact . 630A and 1250A VS1 circuit breaker . 630A and 1250A ZN85-40.5 circuit breaker . 12KV and 24KV earth switch. KYN28A-12 and KYN61 high voltage switchgear components!

        2. The Indoor high voltage isolation switch GN22-12(C) is use for three phase alternating current 50Hz , rate voltage is 12kV .

        3. Altitude is less than 1000 M .

        4. It is mainly used for "isolation power supply, turndown operation, for connecting and cutting off small current circuit", without arc extinguishing function.
The isolation switch, usually referred to as the high voltage isolation switch, is rated voltage above 1kV isolation switch, is the most used high voltage switch electrical appliances, working principle and structure is relatively simple, but because of the high usage, high reliability requirements, the design, construction and safe operation of power substation, power plant has a great impact.
