Brazed Contact Assemblies For High Voltage
Products Description
Brazed Contact Assemblies for High Voltage are core current-switching components in high-voltage electrical switchgear, widely used in circuit breakers, relays, contactors, and various high-voltage switchgear. These assemblies utilize advanced brazing technology to achieve a robust metallurgical bond between highly conductive, arc-resistant contact materials and a high-strength conductive substrate, forming an integrated structure with excellent electrical performance, mechanical strength, and thermal stability. Under harsh operating conditions of high voltage, high current, and frequent operation, they undertake the critical tasks of reliably connecting, carrying, and breaking current, directly affecting the safety, stability, and lifespan of the entire power system.
Product Highlights
Using high-purity metal materials and precision brazing technology, the Brazed Electrical Contacts for Circuit Breakers ensure extremely low contact resistance, excellent conductivity, and stable current-carrying capacity under high-voltage environments, significantly improving equipment operating efficiency and safety.
The Brazed Contacts for Relays structure and high-strength brazed joints can withstand the enormous impact forces, vibrations, and high temperatures caused by electric arcs generated during high-voltage switching and opening/closing, effectively preventing loosening, welding, or deformation, and extending equipment lifespan.
Metal Forming Processes
Precision Stamping and Forming: Utilizing high-precision dies, copper, silver alloys, and other substrates are stamped, bent, and stretched to form precisely dimensional and structurally consistent contact bases, contact bridges, and other components, laying the foundation for subsequent Silver Brazed Contact Tips for Switches.
High-Quality Brazing Technology: This is the core of our process. Vacuum brazing or protective atmosphere brazing is employed, using silver-based and copper-based brazing filler metals with specific formulations. This process achieves a strong metallurgical bond between dissimilar metals in components such as Brazed Contacts for Motor Starters, resulting in joints with high strength, low resistance, good heat resistance, and no flux residue contamination.
