Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. is a leading manufacturer of an expansive array of package substations. These high-performance units primarily consist of a transformer unit, high voltage unit, and low voltage unit. The robust substation shell is crafted from premium materials such as stainless steel, aluminum alloy, cold-rolled plate, and advanced non-metal materials. Known also as the European type transformer substation, the Prefabricated Substation stands out with its innovative engineering.
This advanced substation adeptly handles the transformation, distribution, transmission, measurement, and compensation of electrical energy. It also supports system control, protection, and communication functions. Typically, it includes three main compartments: the High Voltage Compartment (equipped with state-of-the-art high/medium voltage switchgear, such as a ring main unit or gas insulated switchgear, supporting voltages up to 40.5kV), the Low Voltage Compartment, and the Transformer Compartment (featuring a three-phase oil-immersed transformer or a cast resin dry type transformer).


This substation is an essential and pivotal power distribution supply unit within the electrical cable power network. It represents a comprehensive power supply solution equipped with high voltage control, protection, and conversion alongside distribution capabilities. Designed for 3-phase AC 50Hz systems, it supports transformers with a rated current up to 1600KVA, making it ideal for industrial and mining enterprises, as well as residential areas, hospitals, malls, high-rise buildings, and various other distribution systems. The compact prefabricated substation is celebrated for its effectiveness, convenience, and economic advantages. It offers a safe, simple, and user-friendly solution for operating substations.
