Description

Box-Type Prefabricated Substation description

The Box-Type Prefabricated Substation YB-12 series is a high-integrity power distribution complete equipment, widely applicable to indoor and outdoor scenarios including urban power grid renovation, residential communities, high-rise buildings, industrial and mining areas, hotels, shopping malls, airports, railways, oil fields, docks, highways and temporary power supply facilities. The Compact Box-Type Prefabricated Substation YB-12 integrates high-voltage electrical equipment, transformers and low-voltage electrical equipment into a compact power distribution unit, dedicated to electrical energy receiving and distribution in power distribution systems, and is perfectly adapted to urban high-rise buildings, urban and rural buildings, high-tech development zones, small and medium-sized factories, mining areas, oil fields and temporary construction power supply scenarios.

The Box-Type Prefabricated Substation YB-12 boasts outstanding performance advantages such as strong completeness, small size, compact structure, safe and reliable operation, easy maintenance and portability. Compared with conventional civil substations, the same capacity Compact Box-Type Prefabricated Substation only occupies 1/10 to 1/5 of the floor area, drastically reducing design and construction workload as well as overall construction costs. The Box-Type Prefabricated Substation is compatible with ring network distribution systems, dual-power supply systems and radial terminal distribution systems in power distribution networks, and is a new type of core complete equipment for the construction and renovation of urban and rural substations, while the Compact Box-Type Prefabricated Substation further optimizes space utilization for scenarios with limited installation area.

Box-Type Prefabricated Substation functions and Features
