Prefabricated Substation (China-Style)

Hua-Type Substation: An advanced prefabricated substation engineered for diverse power distribution scenarios, perfectly tailored for power grids, wind power, and solar PV projects.

Product Description

Hua-type prefabricated substation is a specialized type of prefabricated substation. It integrates advanced domestic and international technologies, making it suitable for power transformation and distribution systems in various fields, such as industrial parks, urban commercial areas, residential districts, and public facilities. It is particularly applicable to power distribution engineering remote from residential areas, wind power projects, and wind power or solar photovoltaic (PV) projects with large single-unit installed capacities.

Product Advantages

Highlight

Intelligent Design

The entire substation utilizes an intelligent design, with the protection system equipped with an integrated microcomputer automation device to fully support "Four-Remote" functions (Telemetering, Telesignaling, Telecontrol, and Teleregulation).

Highlight

Compact Structure

By eliminating the transformer room, it predominantly utilizes oil-immersed transformers that are directly externally mounted to the enclosure. This results in a much smaller footprint, occupying only about 58% of the space required by a European-type substation.

Highlight

Eco-Friendly & Energy-Saving

The transformer radiators feature an open-style installation to achieve natural ventilation, eliminating the reliability issues associated with forced ventilation fans. This ensures superior cooling efficiency and minimizes power loss caused by overheating. The entire design comprehensively accounts for environmental factors like dust, rain, snow, and sandstorms, making it ideal for long-term outdoor operation.

Highlight

Maintenance & Reliability

The busbar directly connects the high-voltage switch to the transformer, eliminating the operational safety risks associated with cable connections. Equipped with safety devices such as grounding switches, surge arresters, and mechanical interlocks, it guarantees maximum personal safety. Furthermore, the isolation knife, arc chute, and fuse of the high-voltage switch are partitioned into separate compartments, allowing individual unit maintenance without shutting down other equipment.
