YBW-24/0.4 high-voltage/low-voltage prefabricated substation is divided into three parts: high-voltage room, transformer room and low-voltage device. The prefabricated substation combines high-voltage switchgear, transformer, low-voltage switchgear and other auxiliary electrical components into It can adapt to the outdoor operating environment, and can independently complete functions such as voltage conversion and power protection, control, and distribution. The product has diversified design, flexible and convenient combination, and is suitable for distribution network nodes and terminals. It has compact structure, safety and reliability, and small footprint. Advantages such as low cost.
