As a seasoned supplier specializing in stainless steel bellows for vacuum interrupters, we possess exceptional expertise particularly in the field of metal drawn parts supporting vacuum interrupters in the power industry. As the "heart" of high-voltage switches, vacuum interrupters rely heavily on the collaborative performance of their internal bellows and drawn parts, which directly determines arc-quenching efficiency and equipment lifespan. Hence, there are extreme requirements for material compatibility, sealing reliability, and arc resistance of supporting components. Our specially developed drawn parts adopt the same special-grade stainless steel as bellows, and through customized molds, achieve micron-level dimensional matching with bellows flanges. This ensures that the flatness error of the sealing surface after assembly is ≤0.02mm, maintaining zero leakage even after over 100,000 switching operations. Additionally, by optimizing drawing process parameters, a uniform cold-worked hardening layer is formed on the component surface, enhancing arc erosion resistance by 40% compared to ordinary drawn parts—perfectly adapting to the harsh working conditions of vacuum interrupters at 12kV-550kV voltage levels. Currently, our supporting drawn parts have established long-term partnerships with major domestic vacuum interrupter manufacturers, continuously validating their professional quality in key projects such as smart grids and ultra-high voltage transmission.
Customization & Quality Assurance: Based on profound technical accumulation, we offer full-process customized services according to customers' personalized needs—from material selection and structural design to mold development and mass production. We flexibly adjust the number of drawing operations and process parameters to ensure products perfectly fit actual application scenarios. Each drawn part undergoes rigorous performance testing and quality control, with full traceability from raw material incoming to finished product delivery. With stable and reliable quality, we help customers improve production efficiency, reduce overall costs, and jointly promote the precision and efficiency upgrading in the manufacturing field.
