Product Description

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd.is proudly at the forefront of manufacturing, an extensive collection of cutting-edge package substations. Our offerings predominantly feature transformer units, high voltage units, and low voltage units, all housed within enclosures crafted from premium materials like stainless steel, aluminum alloy, cold-rolled plate, and innovative non-metal materials. Known as the European type transformer substation, our meticulously designed Prefabricated Substation is engineered for unparalleled performance and unwavering reliability.
Expertly engineered to excel in all electrical environments, this substation masterfully manages transformation, distribution, transmission, and measurement of electrical energy. It also handles compensation, system control, protection, and seamless communication functions. Typically, it includes three meticulously organized compartments: the High Voltage Compartment, equipped with state-of-the-art high/medium voltage switchgear, such as ring main units and gas insulated switchgear rated up to 40.5kV; the Low Voltage Compartment; and the Transformer Compartment, featuring a choice of three-phase oil-immersed transformers or advanced cast resin dry-type transformers.


This essential substation is a cornerstone in electrical cable power networks, delivering reliable and consistent power distribution.Representing a holistic power supply solution, it encompasses high voltage controlling, protection, conversion, and distribution capabilities. Designed for three-phase AC 50Hz with a rated current up to 1600KVA, it finds extensive applications across diverse industrial and mining sectors.Beyond its industrial applications, this versatile substation is perfect for residential areas, hospitals, shopping malls, high-rise buildings, and other complex distribution systems. Our compact prefabricated substation stands distinguished as an exceptional, user-friendly, and cost-effective solution. It ingeniously combines safety, simplicity, and efficiency, ensuring it integrates seamlessly into any power distribution setup.
