Box-type Substation Testing

The prefabricated box-type substation foundation is a core prefabricated component in State Grid power engineering projects. It is manufactured in factories using standardized processes, with concrete as the main material and a steel reinforcement cage, allowing for rapid assembly on-site. The structure is stable and dense, offering compressive strength, impermeability, weather resistance, and corrosion resistance. It precisely meets the load-bearing and protective requirements for installing box-type transformers. The product complies with the standardized construction requirements of State Grid power engineering projects, offering high installation efficiency, short construction periods, and convenient operation and maintenance. It is widely used in box-type substation deployment scenarios such as urban and rural power grids, new energy supporting facilities, and municipal power construction.
