XGN66-12 type MV fixed switchgear

Description

General:

XGN66-12 box-type fixed metal enclosed switchgear is our factory to design, research and development from a new generation of complete sets of high-voltage electrical products, switchgear suitable for 3,6-12kv three-phase AC 50Hz single bus section of the indoor sets of devices As receiving and distribution of electric energy use, and has the circuit control, protection and detection capabilities. The products absorb advanced foreign technology, in view of the existing switchgear in the operation of similar high accident rate and the large volume of such problems Designed and developed from. It is small, only the common switch cabinet, the circuit breaker with high reliability, good performance, five anti-interlock, reliable, and simple.

 

Environmental Conditions:

1).use the maximum temperature does not exceed 40 degrees, the minimum Not more than -25 degrees

2).relative humidity: daily average of not more than 95%, the monthly average of no more than 90% of the altitude does not exceed 1000m (over time can consult the manufacturer)

3).no fire, explosion, heavy pollution, chemical corrosion and severe Shock sites.
