Application and characteristics of copper tungsten integral contact

Self elastic contact element copper tungsten integrated contact is mainly used for SF6 high voltage circuit breaker. It has its own flexibility, work without additional spring, which has the advantages of simple structure and convenient installation, contact size, is conducive to improve the breaking characteristic of circuit breaker. The WCu20/CuCr0.5 integral contact product WCu contact developed by vertical integral sintering vacuum infiltration method has good burn resistance, little burn loss, good elasticity of CuCr and no deformation of contact finger.

Features: base for tungsten electrode, copper rod, ring shape. 10 components of tungsten copper, tungsten copper tungsten copper 20, 30); the conductive terminal is copper chromium or copper binding surface for two different metals with copper infiltration (project won the National Invention Prize two) by infiltration technology and tungsten two yuan mutual diffusion of copper bound together special melting, table type and parameter of tensile strength than the strength of the copper binding metal bond of two metal connecting copper tungsten contact vertebral hugh.
