Metal-Enclosed High Voltage Switchgear

High Voltage Switchgear Overview XGN15—12/24 -type unit, modular and sulfur hexafluoride RMU is compact and extended metal-enclosed switchgear which use sulfur hexafluoride switch as the main switch ,the entire cabinet is air-insulated and suitable for distribution automation.It owns natures of simple structure, flexible operation, interlock, reliable, which can provide satisfactory technical solution in various different applications and user requirements. The latest sensor technology and the protection relays adopted , together with advanced technical performance and lightweight flexible assembly program, can fully meet the changing needs of the market. XGN15-12/24 type modular cabinet sulfur hexafluoride ring main switches respectively use FLN36/FLN38 type SF6 load switch, load switch Schneider SC6 series, ABB original SFG-type, SF6 load switch, GN30 isolating switch ,can also be according to the needs of users with original equipment VS1 ABB VD4 circuit breaker or circuit breakers, and the fixed circuit breaker type. Main purpose 1. XGN15-12/24 type modular sulfur hexafluoride ring counter apply to the AC 50HZ, 12/24KV the power system, and widely used in industrial and civil cable ring and the power supply terminal project. 2. Especially applies to the following areas: urban distribution area, small secondary substation, switching station, industrial and mining enterprises, shopping malls, airports, metro, wind power, hospitals, stadiums, railways, tunnels and so on. Regular service condition 1. Altitudes ≤ 1000m; (if any special requirements can clarify when ordering) 2. Ambient temperature: a-25 °C +40 °C; 3. On the average relative humidity is not more than 95%; on the average relative humidity is not more than 90%; 4. Seismic capacity: 8 degrees; 5.
