YB typed pre-fabricated substation is for HV/LV equipment,transformer combination of a compactly equipment device.Widely used in urban high-rise buildings,urban and rural construction,residential areas,factories,parks,airports,railway,oil field,shopping malls and
temporary construction and other outdoor venues.For receiving anddistribution of electric energy in power distribution system.
1.Substation shell adopts the surface treatment of steel manufacturing,has enough mechanical strength and rigidity.
2.The shell material is made of cold rolled steel plate,stainless steel plate,aluminum alloy plate,after choi plate,etc
3.Each chamber is use the steel plate into separate little room,the Layout is designed to ''or '' shape based on electricity demand.
4.To convenience to monitoring and maintenance,transformer room,high and low voltage room is equipped with lighting device.
5.The top plate with double-layer structure,to prevent thermal radiation increase indoor temperature.
6.Transformer is with natural ventilation,when the transformer room temperature more than setted temperature,the top of the axial flow fan antomatically start to control the temperature of the transformer room.
7The connection parts equipped with sealing device,has the good moistureproof function.
Perfect protection performance,convenient operation,ensure the Safety of maintenance;
Seismic capacity:8 degrees
|Seismic Capacity||8 degree|
