Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. manufactures a vast array of package substations that primarily include transformer units, high voltage units, and low voltage units. These substations boast of an exterior crafted from high-quality materials such as stainless steel, aluminum alloy, cold-rolled plate, and other non-metal materials. This Prefabricated Substation, also known as the European type transformer substation,
is adept at completing the transformation, distribution, transmission, measurement, and compensation of electrical energy. It seamlessly integrates system control, protection, and communication functionalities. Typically, this substation is composed of three key compartments: the High Voltage compartment, equipped with sophisticated high/medium voltage switchgear like the ring main unit and gas-insulated switchgear, achieving a maximum rated voltage of up to 40.5kV; the Low Voltage compartment; and the Transformer compartment, furnished with state-of-the-art three-phase oil-immersed or cast resin dry-type transformers.


This substation plays a pivotal role as a crucial power distribution supply unit within the electrical cable power network. It embodies a comprehensive power supply set equipped with high voltage controlling, protection, converting, and distribution capabilities. This versatile substation operates in a 3-phase AC 50Hz environment with a rated current capacity of up to 1600KVA. It finds extensive applications across industrial and mining enterprises, residential quarters, hospitals, malls, high-rise buildings, and other distribution systems. The compact prefabricated substation stands out as one of the most effective, convenient, and economical solutions, offering a user-friendly, safe, and straightforward operation for electric substations.
