YBWF/G-40.5/0.69 Wind Power Transformer/Photovoltaic Power Transformer

40.5kV and 12kV box-type step-up transformers for wind power and photovoltaic (solar) applications. Designed for the growing renewable energy market, these transformers efficiently boost the standard 690V output from wind turbines or solar panels to a higher voltage (40.5kV/12kV) for effective power collection and transmission within the farm grid. They are engineered to meet the specific demands and environmental conditions of renewable energy projects in China.
