Medium voltage

High-voltage power equipment ranges from vacuum circuit breakers with high breaking ability to vacuum interrupters, which are core components of VCB, high-voltage magnetic contactors, current-limiting power fuses, and high-pressure gas load switchgear. (Ring main unit), load break switch for distribution automation, and high voltage switch (LBS, ASS, ALTS).

Vacuum Circuit Breaker (VCB) is a circuit breaker to which VI (Vacuum Interrupter) is applied, which uses vacuum as the extinguishing medium. It is an important protection device that automatically shuts off the power system in case of a failure in addition to performing planned power transmission/reception, transfer, and stop.
