Prefabricated substations, also called European substations, are compact integrated power distribution devices composed of high-voltage electrical equipment, transformers and low-voltage electrical equipment that are all independently set with each other and connected using cables. Prefabricated substations are used for power distribution systems in high-rise buildings, airports, residential areas, medium to small factories, mines, oil fields and temporary construction sites for power acceptance and distribution.

Features

‘目’ or ‘品’ shaped structure.
Shell materials: aluminum alloy plates, stainless steel plates, fiberglass reinforced cement boards.
Substation bases are made of a galvanized channel steel or cement, giving them a strong corrosion resistance and exceptional mechanical strength.
Two-layer top cover structure, featuring an excellent thermal insulation, radiation protection, and ventilation effects.
Substations are separated into several independent chambers, and all chambers are equipped with lighting devices. Automatic air exhausting devices are installed on top of the transformers to adjust the temperature inside the transformer chambers.
Flexible colors, matching with surroundings.
