China Metal Stamping Parts for Power Systems - Trusted Suppliers & Factory for Transformers and Switchgears
Product Description
Materials & Process
Given that power equipment operates in high-voltage, strong magnetic field, and complex outdoor environments for a long time, we have achieved dual breakthroughs in material selection and process control. We use special metal materials such as high magnetic induction cold-rolled silicon steel and weathering steel, and realize micron-level dimensional control through multi-station progressive stamping processes. This ensures that the magnetic permeability of core laminations is increased by more than 15%, and the fatigue strength of cabinet connectors reaches 300MPa, fully meeting the long-term full-load operation requirements of power equipment. Components with special surface passivation treatment have passed a 2000-hour salt spray test, maintaining stable performance even in harsh environments such as humidity and dust, thus significantly reducing operation and maintenance costs.
Applications & Standards
From transformer core punches to grounding terminals of high-voltage switchgears, from cable brackets to insulator hardware, our stamping parts have been widely used in power transmission and transformation projects of State Grid and China Southern Power Grid, as well as new energy power station projects. All products have passed ISO 9001 quality management system certification and DL standard testing in the power industry. In projects such as ±800kV UHVDC (Ultra-High Voltage Direct Current) transmission projects and large-scale wind and photovoltaic bases, we have won customer recognition.
Customization Services
We not only provide standardized stamping parts, but also offer customized services from material selection and mold development to mass production according to customers' equipment drawings and working condition requirements. Through simulation analysis and structural design optimization using software such as ANSYS, our products meet mechanical strength requirements while achieving a 30% weight reduction, contributing to the improvement of energy efficiency of power equipment. Choosing our metal stamping parts means choosing to fortify the safety line of the power system and empower the high-quality development of the energy industry with precision manufacturing.
