Testing of Ring Main Unit Foundation

The prefabricated foundation for the Ring Main Unit (RMU) is a core prefabricated auxiliary 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 on-site assembly and positioning. The structure is stable and dense, offering compressive strength, impermeability, weather resistance, and corrosion resistance. It precisely meets the load-bearing, fixation, and positioning requirements for installing ring main units. The product complies with the standardized construction requirements of State Grid power engineering projects, offering high installation efficiency, precise positioning, and convenient operation and maintenance. It is widely used in RMU deployment scenarios such as urban and rural power grids and municipal power supporting facilities, significantly improving construction efficiency.
