Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. is a dedicated manufacturer of an extensive array of package substations, expertly crafted with integral components such as transformer units, high voltage units, and low voltage units. These substations boast robust shell materials like stainless steel, aluminum alloy, cold-rolled plate, and non-metal materials. Often referred to as European type transformer substations, our Prefabricated Substations stand as a testament to engineering brilliance.
These substations perform a multitude of vital tasks: transforming, distributing, and transmitting electrical energy while ensuring accurate measurement, compensation, system control, protection, and seamless communication functions. Typically comprising three primary compartments—High Voltage, equipped with advanced high/medium voltage switchgear like ring main units and gas-insulated switchgear with rated voltages up to 40.5kV; Low Voltage; and Transformer Compartments, fitted with robust three-phase oil-immersed transformers or cast resin dry type transformers—these substations are paragons of modern engineering.


This substation plays an indispensable role as a pivotal power distribution supply unit within the electrical cable power network. It is a comprehensive power supply solution offering high voltage control, protection, conversion, and distribution. Ideal for use with 3-phase AC systems, 50Hz frequencies, and supporting transformers with a maximum rated current of 1600KVA, this substation is extensively utilized across industrial sectors, mining enterprises, residential complexes, hospitals, shopping malls, high-rise structures, and a myriad of other distribution systems. Our compact prefabricated substations are praised as effective, convenient, and economically sound solutions. They offer user-friendly and safe substation operations, making them the epitome of modern utility efficiency.
