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.
