35kV Prefabricated Substation

The YB-series 40.5 kV prefabricated substation for new energy is a specialized power transformation device that steps up the voltage output from photovoltaic and wind power generation units (0.4–1.14 kV) to 35 kV for grid connection. Custom-designed by our company in response to the requirements of the domestic photovoltaic and wind power markets, this packaged substation integrates reliability, safety, versatility, and cost-effectiveness, making it an ideal ancillary product for photovoltaic and wind power generation systems. Solar power generation is broadly categorized into solar thermal power and photovoltaic power; currently, the solar electricity that has entered commercial operation refers specifically to photovoltaic power.

Case Description

Structural Features

A packaged substation consists of three main sections: the high-voltage compartment, the low-voltage compartment, and the transformer. The Huashi-type packaged substation is primarily used as a step-up transformer for new-energy power generation. Its distinctive structural feature—setting the transformer outside the substation enclosure—effectively addresses transformer cooling by leveraging natural environmental conditions to rapidly dissipate the heat generated by the transformer itself. The transformer is connected to the substation enclosure via side-mounted bushings, while internal partitions within the enclosure separate the high-voltage and low-voltage compartments. This design makes it an ideal solution for new-energy power-generation applications.
