The long‑term stable operation of complete power distribution equipment relies heavily on the performance of core components. Recently, Hongsu Electric has continuously upgraded intermediate‑cabinet contact boxes and circuit‑breaker supporting parts, optimized the processes of key accessories such as disc springs and bearing disks, and improved core component performance for complete switchgears.

For high‑voltage switchgears, contact pressure and mechanical part durability directly affect temperature rise, current‑carrying capacity and service life. Through optimized material selection and precision machining, Hongsu Electric improves the fatigue resistance of disc springs to ensure reliable long‑term contact between static and moving contacts. Matching bearing disks reduce friction loss of mechanical mechanisms for mainstream cabinet types including KYN28‑12 and XGN15‑12.

By extending R&D and manufacturing of core spare parts from complete assemblies, self‑supporting of critical components is realized, further improving the consistency and reliability of complete switchgears and providing solid hardware support for power grid, industrial and new‑energy projects.
