Factory Supply Outdoor AC High-Voltage Three Phase 50Hz Vacuum Circuit Breaker

ZW32-12 12kV Outdoor High Voltage Vacuum Circuit Breaker VCB  General IntroductionZW32-12 type outdoor H.V. vacuum circuit breaker is the outdoor distribution equipment with rated voltage 12KV, three phase AC 50Hz. It is used in substation and industrial and mining enterprises distribution system for protecting and controlling use. It is also used in rural power grid places with frequent operation for breaking and closing the load current and over load current and short circuit current of power system.The out insulation of the vacuum interrupter adopt silicone rubber casing, with longer life, higher reliability, good weather resistance, convenient for transportation, good rating. The operating mechanism adopt miniaturization, high reliable spring operation mechanism, has the advantages of simple structure, mechanical life up to 10000 times.This circuit breaker and controller can form a complete set as recloser, realize remote control, telemetry, remote communication, remote adjustment four remote function. Product features: no combustion and explosion hazards, maintenance free, small size, light weight (less than 100kg), long service life (million), safety and reliability, simple operation, convenient maintenance and installation.Working ConditionThe environment temperature: upper limit +40ºC, lower limit -30ºCAltitude ≤ 2000 metersWind pressure: no more than 700Pa (corresponding to the wind speed 34m/s)Earthquake intensity: do not exceed 8 degreePollution grade: III classMaximum daily temperature: less than 25ºC.  Technical parameterNo.ItemUnitValue1Rated voltagekV122Rated frequencyHz503Rated currentA6304Rated short-circuit breaking currentkA205Rated peak withstand currentkA506Rated short-time withstand current (4s)kA207Rated short circuit close current (peak)kA508Mechanical lifetimes100009Rated short open circuit current switching frequencytimes30101 min power frequency withstand voltage(wet)(dry) alternate with, on/fracturekV42/4811Lightning impulse withstand voltage(peak) relative to ground/fracturekV75/8512Secondary loop 1min power frequency withstand voltagekV2ZW32-12FG/T630-25 12kv remote control auto recloser circuit breakerOverview:ZW32-12FG/T630-25 Type Outdoor high voltage vacuum circuit breaker is a outdoor distribution equipment with AC 50Hz,rated voltage 12kV and three-phase ac. It is mainly used for open circuit power distribution network and close the load current, overload current, short circuit current in power system.It is suitable for the transformer substation and factory power distribution system for protection and control use. Especially suitable for urban power grid and rural power grids.Service conditions:1. Ambient Temperature: -40ºC~+65ºC,daily temperature≤25ºC;2. Altitude: ≤2000m 3. Wind speed: ≤35m/s4.
