11kv Combine Substation

We have zbw20(jbw)-12 series enclosed combination substation is independent unit of 50-1600kva distribution device in rated voltage of 10kv, ac 50hz network. It is applicable for the outdoor administration of power supply such as residential area, plants and mines, hospital, park, oil field, airport, railway and temporary facilities. The product is used not only for ring network power supply system, but also for terminal power supply in radiation style.
Feature:
combined with advantage of pad-mounted substation and the prefabricated substation, the product owns advantages as followings:
1. External appearance is similar to that of pad-mounted substation, less occupied area, not so high, impact structure.
2. Sf6 is used in the h. V. Side to prevent from mal-operation and oil ageing, which improves the reliability of operation and reduces maintenance.
Steel sheet or compound sheet can be used for enclosure, so it will be pretty in various types.
