Product Overview :

XGN-12 switchboard is suitable for single busbar systems with power levels of 10KV three-phase AC 50Hz to accept and distribute power. The switchboard is new generation small power equipment used in cities and rural areas. which is distinguished with features as small volume, low cost, safety and dependability, simple in running and operation, and accommodates to the demand of power market, reform of city and rural power grids, and packaged substaions.

Working Conditions:
a. The Ambient temperature upper limit and lower limit are respectively +40°C and -40°C; (allowing storage and transportation at -30°C);
b. Altitude is not more than 1000m;
c. Relative humidity: daily average value should not be more than 95%, while monthly average value should not be more than 90% (+25°C);
d. Seismic intensity should be not more than 8°;
e. Places without fire, explosion risk, serious pollution, chemical corrosion and violent vibration.

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".
