Product Details

36kV Combined Transformer for Photovoltaic power generation

Product Description:

Summarize:
ZGS-Z.F-/36 series wind power combined transformer is a special power equipment integrating step-up transformer, HV current limited fuse, load switch, LV switch and related auxiliary equipments. It transforms the 0.69kV voltage produced by wind power motor into 35kV,and output the electricity through 35KV cable circuit, which is the ideal equipment in wind power complete set equipment.

Normal ambient conditions for service:
1. Altitude shall be within 2000m
2. Ambient temperature range shall be : -40ºC~+40ºC
3. Outdoor wind speed shall not exceeds 35m/s
4. Relative humidity: daily average value shall not exceed 95%, monthly average value 90%
5. Installation site: indoor
6. Service environment: installed in sites with no fire or explosion danger, serious fifth, chemical corrosion and fierce vibration.
7. When transcend the above normal ambient conditions for service, users can negotiate with us to solve.
