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).
