Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. manufactures a wide range of package substations primarily comprising transformer units, high voltage units, and low voltage units. The substation shell materials include stainless steel, aluminum alloy, cold-rolled plate, and non-metal materials. Prefabricated substations, also known as European type transformer substations,
can complete electrical energy transformation, distribution, transmission, measurement, compensation, system control, protection, and communication functions. Typically, these substations have three compartments: the high voltage compartment (equipped with high/medium voltage switchgear like the ring main unit or gas-insulated switchgear, with a rated voltage up to 40.5kV), the low voltage compartment, and the transformer compartment (equipped with three-phase oil-immersed or cast resin dry type transformers).
