Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. proudly manufactures a comprehensive range of package substations, expertly crafted to include transformer units, high voltage units, and low voltage units. The substation's shell is predominantly made from premium materials such as stainless steel, aluminum alloy, cold-rolled plate, and non-metal materials. These substations, also known as European type transformer substations, offer versatility and durability.
These substations masterfully handle the transformation, distribution, transmission, measurement, energy compensation, system control, protection, and communication functions. Typically, they consist of three expertly designed compartments: a High Voltage compartment equipped with high/medium voltage switchgear like the ring main unit or gas insulated switchgear, supporting a maximum rated voltage of 40.5kV; a Low Voltage compartment; and a Transformer compartment furnished with a three-phase oil-immersed or cast resin dry type transformer.


This substation is a pivotal component in power distribution networks, ensuring reliable electrical supply in cable power systems. It is a fully integrated power supply solution featuring high-voltage control, protection, conversion, and distribution, suitable for 3-phase AC 50Hz applications with rated currents up to 1600KVA. Its versatility makes it ideal for industrial and mining enterprises. Additionally, it serves residential areas, hospitals, malls, high-rise buildings, and various other distribution systems with unmatched performance. Our compact prefabricated substation stands out as a highly efficient, convenient, and budget-friendly solution. It provides a safe and straightforward operation, making it one of the most user-friendly options available.
