Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. manufactures a comprehensive selection of package substations, which primarily include transformer units, high voltage units, and low voltage units. The substation shell is crafted using premium materials such as stainless steel, aluminum alloy, cold-rolled plate, and non-metal materials. This innovative Prefabricated Substation is also known as a European type transformer substation.
This versatile substation facilitates the transformation, distribution, transmission, measurement, compensation of electrical energy, system control, and protection, alongside communication functions. Typically, the substation consists of three main compartments: a High Voltage Compartment (equipped with high/medium voltage switchgear like the ring main unit and gas-insulated switchgear, with a rated voltage reaching up to 40.5kV maximum), a Low Voltage Compartment, and a Transformer Compartment (featuring either a three-phase oil-immersed transformer or a cast resin dry type transformer).


This substation is a critical power distribution unit within the electrical cable power network, ensuring reliable and efficient energy supply. It represents a complete power supply system with high voltage control, protection, conversion, and distribution. Designed for use in 3-phase AC 50Hz networks, it accommodates transformers with a maximum rated current of 1600KVA, making it an ideal choice for industrial and mining enterprises. as well as residential areas, hospitals, shopping malls, high-rise buildings, and various other distribution systems. The compact prefabricated substation stands out as one of the most effective, convenient, and cost-efficient solutions, providing a user-friendly, safe, and straightforward operational experience.
