Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd.proudly manufactures an extensive array of state-of-the-art package substations, predominantly encompassing transformer units, high voltage units, and low voltage units. These enclosures are crafted from high-quality materials such as stainless steel, aluminum alloy, cold-rolled plate, and non-metal materials. Known as the European type transformer substation, our Prefabricated Substation is designed for superior performance and reliability.
Engineered to excel, this substation seamlessly manages the transformation, distribution, transmission, measurement, compensation of electrical energy, as well as system control, protection, and communication functions. Typically, it includes three meticulously organized compartments: the High Voltage Compartment, featuring advanced high/medium voltage switchgear like ring main units and gas insulated switchgear with a maximum rated voltage of 40.5kV; the Low Voltage Compartment; and the Transformer Compartment, equipped with either a three-phase oil-immersed transformer or a cast resin dry-type transformer.


This substation is a vital component in the electrical cable power network, ensuring dependable power distribution.It represents a comprehensive power supply solution featuring high voltage controlling, protection, converting, and distribution. Designed for three-phase AC 50Hz with a rated current up to 1600KVA, it finds extensive application across industrial and mining sectors.In addition to its industrial uses, this substation is ideal for residential areas, hospitals, malls, high-rise buildings, and other sophisticated distribution systems. Our compact prefabricated substation stands out as an exceptional, user-friendly, and cost-effective solution. It combines safety, simplicity, and efficiency, making it a seamless addition to any power distribution setup.
