Combination Substation ZBW1 Series

Combination Substation ZBW1 Series

    To meet requirement of urban network construction, ZBW1 series combination substation is designed by our company with its own advantage such as impact, complete unit, reliable and safe, convenient maintenance, artistic appearance and so on. It is applicable for the outdoor administration of power supply such as high building, residential area, stations and wharfs, ports, parks, department store, factory and
mines. The product is used not only for ring network power supply system, but also for terminal power supply in radiation style. In 1991, the product has been approved by National Mechanical & Electrical Ministry and National Energy Ministry, which was first in China. Its performance is up to advanced level in China.

Feature :
 
      1. The frame of substation is made of steel and angle iron galvanized to have the enough mechanical strength.
      2. Cold-rolled steel sheet, stainless steel, aluminum alloy sheet or compound colorful sheet is used for the enclosure.
      3. Each cubicle is separated by steel sheet to be different shape inside.
      4. The illuminating devices are installed inside L.V.&H.V. cubicles and transformer cubicle for supervision and maintenance.
      5. The cover is double-layer to prevent the heat from increasing temperature.
      6. Natural ventilation is taken for transformer. When the temperature inside the transformer cubicle is higher than the set temperature, the fan installed on the top will start to work and control the temperature.
      7. Sealing devices are put on the turning parts to be moisture-proof.
      8. Perfect protection and convenient operation, particularly "five-proof"functions on H.V. side ensures the security of maintenance.
      9. The product is good-looking and natural in certain environment
