Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. proudly manufactures a comprehensive assortment of package substations, which primarily consist of a transformer unit, high voltage unit, and low voltage unit. The substation’s shell material predominantly includes robust stainless steel, durable aluminum alloy, resilient cold-rolled plate, and non-metal materials. Notably, the Prefabricated Substation is also referred to as a European type transformer substation,
capable of efficiently executing the transformation, distribution, transmission, measurement, and compensation of electrical energy. It also handles system control, protection, and communication functions. This substation is typically comprised of three compartments: the High Voltage Compartment, equipped with high/medium voltage switchgear such as a ring main unit or gas insulated switchgear, reaching rated voltages up to a maximum of 40.5 kV; the Low Voltage Compartment; and the Transformer Compartment, which houses a three-phase oil-immersed transformer or a cast resin dry-type transformer.


This sophisticated substation serves as a crucial power distribution supply unit within the electrical cable power network. It represents a comprehensive power supply system with high voltage controlling, protection, and converting, as well as distribution capabilities. Designed for use with three-phase AC 50Hz and supporting a rated current up to a maximum of 1600KVA transformer, it finds extensive applications in industrial and mining enterprises, 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 economical options. Offering friendly solutions, it is renowned for being safe and simple to operate.
