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)

be varied by composition-more silver or copper yields higher electrical and thermal conductivity, while a higher refractory metal content results in superior arc erosion properties. Mi-Tech Metals offers a variety of composites to meet your demands. Regardless of the environment (oil-filled devices, air and gas circuit breakers, contactors, high voltage switch gear) or the application (arcing contacts and plates, arc runners, current carrying members and blade facings), you won't be disappointed...

DLRO200-115E New Digital Low Resistance Ohmmeter
voltage circuit breakers, disconnecting switches (isolators), busbar joints, or for any low resistance measurement. The test set accurately measure resistances ranging from 0.1?? to 1??, at high currents. This versatile instrument can provide test currents from 10 amps up to 200 amps, subject to the load resistance and supply voltage. For those applications that demand a smooth dc current, the DLRO200-115 has extra filtering on the output to reduce mains frequency ripple and can drive 200 amps... (read more)
