Outdoor 33KV 35KV 36KV 38KV Motorized Spring Type Vacuum Switch / Electric Vacuum Circuit Breaker/Auto Circuit Recloser
ZW32 type high voltage Outdoor 3 pole Vacuum Capacitor Switch(auto circuit recloser) it is a long mechanical life vacuum switch that provides an operational life of over 100,000 (30,000 open / close) maintenance-free operations. Use ZW32 will result in substantial savings from reduced maintenance and maximized bank uptime and will also improve power quality. It complies with standards ANSIC37.66 and China standard. For this vacuum switch, ZW32-40.5 availiable has 33KV 35KV 36KV 38KV 40.5KV. It has motorized spring type & magnetic actuator (with control box) type.
33KV Outdoor Vacuum Circuit Breaker Installation dimensions:
How to wire with vacuum switch
Make sure the end -user follow below diagram to connect the junction box to ZW32 vacuum switch. Junction box is self-power supply controller
Before employ switch for H.V.line, please make sure each cable connector is correct connection.
Please push each A.B.C phase switch button to check if connection in good condition. The proper work is each phase electric control is corresponding correct phase switch.
