ZBW Series Movable Prefabricated Substation,High Voltage Switchgear
1. Overview of ZBW Series Movable Prefabricated Substation,High Voltage Switchgear
The SYZBW series of portable prefabricated substations combine high-voltage electrical equipment, transformers, and low-voltage electrical equipment into a compact complete set of power distribution devices. This type of box-type substation has the functions of an ordinary box-type substation and is mobile. Function.
2. Purpose of ZBW Series Movable Prefabricated Substation,High Voltage Switchgear
SYZBW is suitable for power systems with a rated voltage of 12KV. It is widely used in coal mines, copper mines and other mines and places where electrical equipment such as road construction needs to be moved frequently to meet the requirements of electrical equipment, and used for receiving and distributing electrical energy in the power distribution system.
3. Main features of ZBW Series Movable Prefabricated Substation,High Voltage Switchgear
- The product shell material adopts aluminum alloy plate, stainless steel plate, composite plate, glass fiber, reinforced cement board, etc.;
- The substation base is made of galvanized channel steel or cement, with strong corrosion resistance and sufficient mechanical strength;
- The top cover of the box adopts a double-layer structure, which has good heat insulation, radiation protection and ventilation effects;
- Each room of the substation is separated by iron plates to form an independent small room, and each room is equipped with lighting facilities. The top of the transformer room is equipped with an automatic exhaust device to adjust the temperature of the transformer room;
- The color of the box body of the box change is flexible and can be coordinated with the surrounding environment.
