Box type substation New Energy (photovoltaic/wind)Power (Generation Special Box Transformer)

New Energy (photovoltaic/wind)Power (Generation Special Box Transformer)

Rated voltage10kV/20kV/35kV
Rated capacity630-5000kVA


As a production method of clean energy, new energy power generation has developed rapidly at home and abroad.ZGSseries new energy (photovoltaic/wind)power generation combined transformers is pad-mounted transformer, whichcombines transformer body,oil immersed load switch, oil immersed fuse,switchgear, low voltage power distribution device and other supporting equipment. The high and low voltage chambers and transformers are arranged in triangle shape.Itcan simultaneously meet various configuration requirements such as user energy metering, reactive power compensation,  low-voltage shunt,etc.It is suitable for terminal power supply systems of 35kV and below,  with a capacity range of 500– 5000kVA.  The enclosure protection level can reach IP54 or above,  and it is suitable for photovoltaic and wind farms on land, water and sea.
