11KV ARC Cable Branch Box Compact Transformer Substation IP4X for Dock
IP4X 11KV Arc Cable Branch Box Compact Transformer Substation for Dock
Product Description
The Compact Transformer Substations have the characteristics of strong complete set, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. Compared with conventional civil substations, box-type substations of the same capacity usually occupies only It is 1/10~1/5 of the conventional substation, which greatly reduces the design workload and construction volume, and reduces the construction cost. In the power distribution system, it can be used in the ring network power distribution system, and can also be used in the dual power supply or radiation terminal power distribution system. It is a new complete set of equipment for the construction and transformation of current urban and rural substations.
This series of substations are suitable for 12kv, 50HZ three-phase AC systems with a capacity configuration below 2500kva, residential quarters, commercial buildings, hotels, high and low buildings, industrial and mining enterprises and other places. It is suitable for ring network power supply and also suitable for radiation terminal power supply.
