Tungsten Copper Electrical Contacts
Tungsten copper (WCu) is used for arcing contacts in SF6 circuit breakers for ultra-high, high and medium voltage applications. At the heart of the switching chamber, WCu contacts are exposed to extreme mechanical and thermal loads: When the circuit is opened and closed, the arc starts directly at the switch contacts at a temperature of up to 20 000 °C. Tungsten-copper is popular because of its combination of unique material properties. A high level of temperature resistance is one of the most... (read more)
