Product Description

Our factory

We are professional manufacturer of current transformer ,voltage transformer, Vacuum Circuit Breakers/Recloser,Isolation switches,Dropout Fuse Cut-out,Lightning Arresters,High and Low Voltage Cabinets,Metering Devices,Power Distribution Transformers  etc.
12kv Outdoor Sf6 Smart Air Auto Recloser Electric Electrical Load Break Switch Load Breaker Lbs Vacuum Circuit Breaker
General


Zw43-12 series intelligent outdoor high-voltage AC vacuum circuit breaker (hereinafter referred to as "intelligent circuit breaker"), which is an outdoor power distribution switchgear with a rated voltage of 12kV and three-phase AC 50Hz, mainly consists of ZW43-12 outdoor high-voltage AC vacuum circuit breaker body, DK series distribution automation feeder terminal, external voltage transformer, and control cable, etc. Arrester, single-side disconnector, or double-side disconnector can be installed according to user needs.

ZW43-12C outdoor high-voltage AC vacuum recloser has overload and short circuit protection, quick break protection, definite time-delay protection, and automatic recloser functions, effectively ensuring the good operation of the line.

ZW43-12F outdoor high-voltage AC boundary vacuum circuit breaker has a remote management mode, protection control function, and communication function, which can be reliably judged. The detection boundary is used for control and protection in substations, industrial and mining enterprises, and urban and rural power grids. It is especially suitable for places requiring frequent operation and urban milliampere zero sequence current and interphase fault short circuit current, which can automatically remove single-phase ground fault and interphase short circuit fault.

The intelligent circuit breaker complies with the technical standards such as High Voltage AC Circuit Breaker (GB/T1984-2014), High Voltage AC Circuit Breaker (DL/T402-2016), Technical Conditions for Ordering 12kV~40.5kV High Voltage Vacuum Circuit Breaker (DL/T403-2000) and Remote Terminal of Distribution Automation System (DL/T721-2013).
