YB □ -12 / 0.4 high voltage/ low voltage prefabricated substation
medium voltage recloser, circuit breaker, RMU, switchgear manufacturer - New Concept Electric
  • YB□-12/0.4 high voltage / low voltage prefabricated substation is based on the on-site service and operation experience of prefabricated substation for many years, and it absorbs foreign advanced technology and design concept. A new product designed and manufactured for the distribution network. It has excellent performances such as reliable power supply, reasonable structure, fast installation, flexibility, convenient operation, small size and beautiful appearance. It is mainly used in urban and rural power grids of 10/11/12kV, and is also suitable for industrial and mining enterprises, airports, stations, ports, highways, subways and other public places.

  • Feature

    Compact structure, small volume, small footprint, easy to transport,  triangle and abreast assembly types.
    The shell is designed and produced by using domestic advanced technology and selecting new materials. It has the characteristics of strong, heat-insulating, dust-proof, moisture-proof, and anti-small animals. The shell can be made of steel, composite, non-metal and other materials.
    It adopts labyrinth plate structure, which not only has beautiful appearance, convenient disassembly, but also has good thermal performance of ventilation fan.

    Fully insulated and fully protected design. The frame structure of the box is made of channel steel and angle steel. It has sufficient mechanical strength. The inner and outer surfaces of the parts of the box are treated with anti-corrosion coating to ensure no corrosion for a long time and a durable protective layer. The top cover of the cabinet is double-layered to prevent heat radiation to increase the indoor temperature.

    The protection performance is perfect, the operation is convenient, and the high and low pressure sides can be metered.

    All the doors of the cabinet do not have the lighting device for opening and closing the automatic switch.

    All the doors of the cabinet are opened outwards, the opening angle is greater than 90°, and there are positioning devices. The door is equipped with handles, hidden doors, and is equipped with locks that protect against rain, rust and blockage.
