GENERAL
YB type series combined substation is a compact complete set of power distribution devices that combines high-voltage electrical equipment, transformers, and low-voltage electrical equipment. It is used in urban high-rise buildings, urban and rural buildings, residential quarters, high-tech development zones, small and medium-sized factories, mines, oil fields, and temporary construction power consumption for receiving and distributing electric energy in the power distribution system.
This product has the characteristics of strong completeness, small volume, compact structure, safe and reliable travel, convenient maintenance, and movable. The floor area is only 1/10 ~1/5 of that of a conventional civil substation with the same capacity, which greatly reduces the construction cost. In the distribution system, it can be used in ring network distribution systems, dual power supply, or radial terminal distribution systems. It is the preferred new complete set of equipment for the construction and transformation of urban and rural substations.
The product symbol is GB/T 17467 high voltage / low voltage preinstalled substation and EC1330 standard.
