XGN2-12 Fixed Type Metal-Clad Switchgear 

Type: XGN2-12

Application

     Our  XGN2-12 Fixed Type Metal-Clad Switchgears are suitable for 3.6, 7.2, 12KV 3-phase AC 50/60Hz power system. Used for power receiving and distribution.

General

XGN2-12 Fixed Type Metal-Clad Switchgear is a box-type, fixed and enclosed equipment , suitable for occasions of frequent operation. The elemental framework is made of welded angle irons.  The main switch of this cabinet adopts vacuum contactor or ZN28A-10(12) series vacuum circuit breakers and CT series spring maneuvering mechanism. Isolating switch adopts GN30-10 super current isolating switch series

Ambient conditions

1. Ambient temperature: upper limit +40; lower limit: -25
2. Altitude no more than 1000m
3. Relative humidity: daily average humidity no more than 95%, and monthly average no more  than 90%
4. Steam pressure: daily average pressure no greater than 2.2×103MPa, monthly average no greater than 90%
5. Seismic intensity no greater than 8 degree
6. No fire, explosive danger, grave filth, chemical corrosion and drastic vibration on the site.

Advantages

• This switchgear is case metal-enclosed structure. In accordance with the national standard GB3906 and international standardIEC298, protection degreeIP2X. The metal-enclosed structure effectively prevents short-circuit failure by intruders .
• When air insulation distance between polar to polar or polar to ground ≤125mm, porcelain support insulators (≥8000N) is applied. All these ensure higher insulation intensity and stability.
• Breakers, both upper and lower insulation switches, grounding switches and interlock mechanisms between doors all takes force mechanical lock mode to meet the requirement of "five- prevention".
