Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. proudly manufactures an extensive range of package substations, mainly comprising a robust transformer unit, a high voltage unit, and a low voltage unit. The substation's shell is expertly crafted from stainless steel, aluminum alloy, cold-rolled plate, and non-metal materials. This innovative Prefabricated Substation, also known as the European type transformer substation,
is designed to efficiently manage the transformation, distribution, transmission, measurement, and compensation of electrical energy. It also facilitates system control, protection, and communication functions. Typically, this substation houses three integral compartments: the High Voltage Compartment (equipped with high/medium voltage switchgear, such as ring main units or gas-insulated switchgear, rated up to a maximum of 40.5kV), the Low Voltage Compartment, and the Transformer Compartment (fitted with either three-phase oil-immersed transformers or cast resin dry-type transformers)


This substation plays a crucial role as a vital power distribution unit within the electrical cable power network. It stands as a complete power supply system with high voltage control, protection, conversion, and distribution capabilities. Designed for use in 3-phase AC 50Hz systems, it supports a maximum rated current of 1600KVA transformers. It is extensively utilized in industrial and mining enterprises, residential areas, hospitals, malls, high-rise buildings, and other distribution systems, offering unparalleled reliability. The compact prefabricated substation represents one of the most effective, convenient, and cost-efficient solutions, providing enhanced safety and simplicity in substation operations.
