Three Phase Dry Type Compact Secondary Substation for Transmission and Railway
Product Description
The Compact Transformer Substations are characterized by their complete set of strong equipment, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. When compared to traditional civil substations of the same capacity, box-type substations generally occupy only 1/10 to 1/5 of the space, significantly reducing design workload, construction volume, and cost. These substations can be used in ring network power distribution systems, as well as dual power supply or radiation terminal power distribution systems. They are a new, comprehensive equipment set for constructing and transforming current urban and rural substations.
This series of substations are suitable for use in 12kv, 50Hz three-phase AC systems with a capacity configuration below 2500kVA, such as residential quarters, commercial buildings, hotels, high and low buildings, and industrial and mining enterprises. They are suitable for ring network power supply and radiation terminal power supply.
Under normal use conditions, the ambient temperature should be within -25°C to 40°C, the vertical inclination should not exceed 5°, the altitude should not exceed 1000 meters, and the outdoor wind speed should not exceed 35m/s.
