Product Details

The YB series pre-assembled substation integrates high-voltage equipment, transformers, and low-voltage equipment into a compact, complete power distribution unit. It is designed for applications such as urban high-rise buildings, mines, oilfields, and temporary construction sites, serving to receive and distribute electrical energy within power distribution systems.

The YB series features a highly integrated design, compact size, safe and reliable operation, ease of maintenance, and portability. Compared to conventional civil-engineered substations, a box-type substation of the same capacity typically occupies only one-tenth to one-fifteenth of the footprint, significantly reducing design and construction workloads as well as overall construction costs. Suitable for use in ring-main, dual-power, or radial/terminal distribution systems, this product represents a modern, integrated solution for the construction and renovation of substations in both urban and rural areas.

The product complies with the national standard GB/T 17467-1998, "High-voltage/low-voltage pre-fabricated substation."
