HYBW-40.5 Prefabricated Box-type Substation

Small Footprint
This packaged substation occupies only about 1/5 to 1/4 of the area required by a traditional brick-and-mortar substation (or station) with the same transformer capacity.

Lower Overall Cost
This packaged substation reduces land costs, construction expenses, and the cost of high- and low-voltage equipment cabinets. Its total cost is approximately 1/3 to 1/2 of that for a conventional substation with the same capacity.

High Power Supply Quality
Equipped with energy-saving and environmentally friendly S-series fully sealed oil-immersed transformers or SCB-type dry-type transformers, this packaged substation features low no-load loss, low noise, and no environmental pollution. Additionally, its compact size allows installation close to the load center, reducing line losses and ensuring high-quality power supply.

Reduced Maintenance Workload
With a protection rating up to IP43, this packaged substation is dustproof, rainproof, protected against small animals and misoperation, providing high supply safety and reliability. The internal components are compactly assembled and feature comprehensive automated monitoring functions, which effectively reduce maintenance efforts.

Easy Installation and Reliable Operation
After reasonable on-site prefabrication, the unit can be lifted and installed as a whole, securely fastened to the foundation, then connected, commissioned, and put into operation with ease.

GB/T 17467 — High Voltage/Low Voltage Prefabricated Substation

DL/T 537 — High Voltage/Low Voltage Prefabricated Substation

The 40.5 kV box-type substation is a compact, prefabricated substation primarily composed of the transformer body, high-voltage electrical components, low-voltage electrical components, and the enclosure. The product features a rational design, convenient installation, and simple operation.
