Engineered around safety, efficiency and uptime

Overview

As cities densify, conventional civil-built switching stations are constrained by land and planning. The XGW box-type station needs no civil construction, occupies little ground, offers flexible configuration and more reliable supply, and greatly shortens construction, installation and commissioning time at a lower overall cost.

Overview

The station integrates fully commissioned 12/24 kV switchgear, circuit breakers, load switches, CT/VT, station PT, FTU/RTU, communication control unit (CCU), metering with automatic meter reading, UPS and indicating instruments into one movable, sealed, moisture-proof stainless-steel enclosure — achieving primary/secondary integration and modular assembly for urban distribution networks.
