Vacuum interrupters

A vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage and high-voltage circuit-breakers.Since the arc is contained within the interrupter, switchgear using vacuum interrupters can be very compact compared with switchgear using air, SF6 or oil as the arc-suppression medium. Vacuum interrupters can be used for circuit-breakers (VCB), load break switches (LBS), contactors, rail circuit breakers, etc. Circuit breaker vacuum interrupters are primarily used in the power sector in substation and power-generation facilities, and load-switching vacuum interrupters are used for power grid end users.We support national and international standards like ANSI/IEEE C37.60, IEC 62271-100, JIS, GB and GOST.
