Hua-style Box-type Substation
The Hua-style transformer substation is structurally different from both American-style and European-style transformer substations. It features a unique R-type high-voltage connection and independently structured units, with separate transformer compartments, high-voltage switchgear compartments, and low-voltage switchgear compartments, which are connected by wires to form a complete power supply system. With its rational design, easy installation, and simple operation, it avoids the limitations of American-style transformer substations and has significant cost advantages compared to wind (photovoltaic) European-style transformer substations. It is applicable to new energy generation sites with broad prospects.
