GVS***4 Series Embedded Poles Type High Voltage Vacuum Circuit Breaker
GVS***4 series embedded poles type high voltage vacuum circuit breaker apply for rated voltage *4Kv, frequency *0Hz three-phase AC power system, widely used in power plants, substations, petrochemical, metallurgical, manufacturing, airports and communities, use for electrical facilities’ protection and control, especially for frequency operating under the rated current or more time for short-circuit interrupting the place. With the VD4, VEP circuit breaker full realization of interchangeable, can be installed on away-style or fixed air-insulated switchgear cabinet. The product accordance to GB***4 “AC high voltage circuit breakerâ€, DL/T**3 “*2~*0.5Kv indoor AC high-voltage circuit breaker order technical conditionâ€; and IEC****4, IEC*******0 and other related standards.
GVS***4 series embedded poles type high voltage vacuum circuit breaker adapt to APG advanced technology, directly to put the vacuum interrupter room and lead electrical circuit solid seal in epoxy resin post then become the way of solid sealing insulation, represents the highest level of the design and manufacture of high voltage vacuum circuit breaker today world.
Note: this models vacuum circuit interrupter chamber seal replaced with ordinary insulation tube column installation method, the model GVS***4P.
