Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. proudly manufactures a wide range of package substations, expertly designed to include essential components such as a transformer unit, high voltage unit, and low voltage unit. The shell material of our substations can be crafted from stainless steel, aluminum alloy, cold-rolled plate, and even non-metal materials. Known as the European type transformer substation, our Prefabricated Substation exemplifies innovation and performance.
this state-of-the-art substation is engineered to efficiently manage the transformation, distribution, transmission, measurement, and compensation of electrical energy. It also excels in system control, protection, and communication functions. Typically, the substation is composed of three distinct compartments: The High Voltage Compartment, equipped with high/medium voltage switchgear like ring main units and gas-insulated switchgear, reaching up to an impressive 40.5kV maximum. The Low Voltage Compartment, and the Transformer Compartment, which features a three-phase oil-immersed transformer or a cast resin dry-type transformer, showcase our commitment to cutting-edge technology and reliability.


This substation plays a crucial role as a pivotal power distribution supply unit within the electrical cable power network. It represents a comprehensive set of power supply solutions, incorporating high voltage controlling, protection, conversion, and distribution capabilities. Designed for use in 3-phase AC with a 50Hz frequency and a maximum rated current of 1600KVA, it finds widespread application in industrial and mining enterprises. residential areas, hospitals, malls, high-rise buildings, and other sophisticated distribution systems. The compact prefabricated substation stands out as one of the most effective, convenient, and cost-efficient equipment solutions, offering a user-friendly, safe, and straightforward operational experience.
