Product Overview
The YBM and YBP series prefabricated substations are compact complete power distribution devices that combine high-voltage electrical equipment, transformers, low-voltage electrical equipment, etc. They are used in urban high-rise buildings, urban and rural buildings, residential communities, high-tech development zones, small and medium-sized factories, mines, oil fields, and temporary construction power supply sites to receive and distribute electrical energy in power distribution systems. The YBM and YBP series prefabricated substations feature strong completeness, small size, compact structure, safe and reliable operation, easy maintenance, and mobility. Compared with conventional civil engineering substations, the same capacity box-type substation usually occupies only 1/10 to 1/5 of the area of a conventional substation, greatly reducing design and construction workload and lowering construction costs. In power distribution systems, they can be used for ring network distribution systems, dual power supply, or radial terminal distribution systems. They are new types of complete equipment for urban and rural substation construction and renovation. The YBM and YBP series prefabricated substations comply with the standards SD320-1992 "Technical Conditions for Box-type Substations" and GB/T17467-1998 "High Voltage/Low Voltage Prefabricated Substations."
