Tungsten Copper SF6 Circuit Breakers Contacts

What We Produce:

We produce high quality tungsten copper SF6 circuit breakers contacts Oil Circuit Breaker switchgear Contacts including Fixed Female and Moving Male Contacts in various application.

Strict Quality Requirements:

Through vacuum infiltration process, our tungsten copper alloy pass through air-content test with good results: O2< 50ppm, N2< 20ppm, H2<5ppm.
With strict quality requirements and production controls, our products comply with ASTM B702.

Adjustable Proportions With Accurate Requirements:

We can optimize arc erosion properties by adjusting right proportions of tungsten and copper. With consideration of voltage and current intensity with economic considerations, we can offer different content varing from 60% to 90% by weight to reach your precise requirements.Tungsten copper contacts has great advantage of high level temperature resistance in tungsten and nice electrical and thermal conductivity in copper.
With the result and excellent products performance in customers’ application, you can trust us for sourcing the desired products.

Suitable Application:

Tungsten copper circuit breakers contacts are widely used as electrical switches for breaking a circuit for high and medium voltage applications. They are also applied in different circumstance like in air, oil, various gases and vacuum.
In SF6 circuit breakers, tungsten copper arcing contacts may withstand extreme high temperature above ≥ 20,000 K, which means huge mechanical and thermal stresses.
