Explore our full range of high- and low-voltage electrical equipment, including switchgear,
transformers,and prefabricated substations designed for reliability and safety.
This product is composed of a high-voltage distribution device, a transformer, and a low-voltage distribution device, which are connected and divided into three functional compartments: the high-voltage compartment, the transformer compartment, and the lo
The high-voltage chamber has a compact and reasonable structure, and has comprehensive anti misoperation interlocking function. When requested by the user, the transformer can be equipped with tracks to facilitate the entry and exit of the doors on both s
Two methods, natural ventilation and forced ventilation, are used to ensure good ventilation and cooling. Both the transformer room and the low-voltage room have ventilation ducts, and the exhaust fan has a temperature control device that can automaticall
The box structure can prevent rainwater and dirt from entering and is made of special baffles, aluminum alloy plates, steel plates, composite plates, stainless steel plates, non-metallic materials (glass fiber cement), etc. After anti-corrosion treatment,
Product Description：
YB Kou-12/24 series prefabricated substations have the characteristics of strong completeness, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. Compared with conventional civil substations, box type substations of the same capacity usually occupy only 1/10~1/5 of the conventional substations, greatly reducing the design and construction workload and construction costs. In the distribution system, it can be used for ring network distribution systems, as well as for dual power or radiation terminal distribution systems. It is a new type of complete equipment for the construction and renovation of urban and rural substations.
Application field：
The YB Kou-12/24/0.4 series prefabricated substation is a compact and complete set of distribution equipment that combines high-voltage electrical equipment, transformers, low-voltage electrical equipment, etc. It is used in high-rise buildings, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, mining and oil fields, and temporary construction sites for receiving and distributing electrical energy in the distribution system.
