Product Description

ZN8-12Q/75X140 Epoxy Resin Support Insulator with Switcgear



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 load switch adopts the pressure gas internal blowing structure, the arc extinguishing ability is strong, and does not affect the interphase and ground insulation, both the dynamic and static contacts have the arc contact, greatly increased the number of breakdowns.



3. The fuse and the load switch room form the transformer protection circuit. The high voltage flow limiting fuse is installed in the insulated shell of epoxy pouring. After the fuse is broken, the firing pin is ejected and the load switch is divided.
