Tungsten Copper Contact Application
Tungsten copper contact has excellent mechanical property and conductivity, which has a broad prospect in EDM and electrical contact materials. It has many applications, such as vacuum switch, high-voltage switch, air circuit breakers, contactors and some electronic devices and so on.
Tungsten copper contact for vacuum breaker has small volume, light weight and suitable for frequent operation and been widely used in distribution network. Both of arc-quenching medium and the gap after the arc after the insulation medium are in vacuum state.
Tungsten copper contact for air breaker is an important component in low-voltage distribution network and electric drive system, which can prevent it from overloading based on contacting and breaking circuit.
Tungsten copper contact for high-voltage breaker is kind of oil-free switchgear that uses SF6 gas as arc quenching medium and insulating medium. It has better performance in arc extinguish and insulation than oil circuit breaker and has high requirement of application, management, operation of SF6. So it main used for the voltage level of 110kv.
Tungsten copper contact for high-voltage breaker is also called as high-voltage switch, which not only plays an important role in cutting or closing high-voltage circuit in the no-load current and load current, but also in protecting relay when short circuit.
Tungsten copper contact for electronic has excellent wear and corrosion resistance and mainly used for controlling electron motion in vacuum, air or solid. So it has a wide range of application, such as electronic components, connectors, semiconductor discrete devices, electro-acoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches and other electronic chemical materials and parts.
