Outdoor Intelligent Small Switch StationXGW15-12
Product Introduction
The intelligent U-type switchgear (including the outer ring switchgear) is a movable, sealed, and moisture-proof stainless steel box that adopts and draws on advanced foreign technologies to install and debug 12kV switchgear, circuit breakers, load switches, current and voltage transformers, 12kV electrical PT, FTU, RTU, communication control terminals (CCU), 12kV metering and automatic meter reading, UPS power supply, and indicator instruments from the inside. Integration of primary systems The modularization of assembly has shortened the construction cycle and greatly improved the reliability of urban electricity transportation.
