Model: XGW-12~24kV Ring Cage(opening and closing)

Application:

XGW-12~24KV ring net cage (opening and closing station) is a new generation of ring net switch equipment with modularization, multi-function, high reliability, compact structure and maintenance-free. It is suitable for ring net power supply or double radiation power supply of 10~35KV power supply lines, and can also be used for terminal power supply, which can control and protect electric energy in the power supply area. Widely used in urban ring network distribution with high power supply load density and cable-fed network, large factories, residential quarters and so on.

XGW-12~24KV ring cage (opening and closing station) is mainly composed of SF6 gas insulated and closed compact switch gear (C-GIS) and metal (or nonmetal) outer box. All high-voltage live parts are enclosed in SF6 gas insulated stainless steel box, which can be freely combined according to the arrangement of incoming line unit, outgoing line unit, metering unit, contact unit and PT (power supply) unit according to user's needs, and can be loaded into power distribution automation system.

In the ring network cabinet, only FTU/RTU and communication device are needed to communicate with the control center of the distribution automation system, and the voltage and current of the line can be varied.

Measure the electric quantity and monitor the working state of each switch.

Features:

● Ambient temperature: +45℃~-35℃, maximum temperature difference ≤25℃;

● Altitude: ≤4000m;

● Humidity: the daily average relative humidity is less than 95%; Daily average value of steam pressure < 2.2kPa; Average monthly relative humidity < 90%; Average monthly steam pressure < 1.8kPa;

● Seismic capacity: the seismic intensity shall not exceed 8 degrees;

● The surrounding air should be free from obvious pollution such as corrosive or combustible gas and water vapor;

● When the outdoor high pressure ring network cabinet is used beyond the normal use conditions, it needs to be negotiated with the manufacturer and reached an agreement.
