Product introduction:

We encapsulate the vacuum interrupter, main circuit live parts, high-accuracy voltage and current sensors, and high voltage pickup capacitors inside the cycloaliphatic-epoxy poles, based on decades of experience in solid insulation technology, eliminating all the partial discharge problems. The poles can pick up the voltage or current signals from power source side and secondary side at the same time, also the capacitor can power supply the intelligent electronic device (IED).

The actuator is small and spring actuated, located in the sealed tank. The circuit breaker can be operated open and close manually, automatically and remotely.

Three-phase linkage disconnecting switch, with a mis-operation locking, can also be connected to the circuit breaker.

Note: Technical datas and sketches are only for your reference. Such details in our contact prevail.
