Wall Through Insulating Bushing For Transformer 36kV High Voltage with three busbar holes
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. In pouring, pouring material is the key. It has a great influence on the reliability and stability of cemented pole. For example, Xiamen Huazhong Electric Switching Co., Ltd. uses the resin materials of Vantico, Switzerland, and adopts different formulas according to different current, etc. to meet different working conditions .
3. The APG process includes three processes: pre-mixing, automatic pressure gel, and solidification after molding.
4. Applicable system: 35 KV or below voltage level of the ground,
small resistance grounding, arc coil grounding, direct grounding
system;
Protection range: not only can be used for line protection, such as
line protection, but also can be used for, PT, main change reserve
protection, motor, capacitor, reactor protection .
