Materials details
CuW50 and CuW55 have the lowest Tungsten contents. They are both good switching
and contact materials for oil filled devices. CuW55 is also used
for arcing contacts in oil circuit breakers and arcing edges of
selectors and switchblades in transformer tap changers.
CuW65 and CuW70 are used as contact materials in severe arcing applications
including gas, oil and some air circuit breakers. They are also
used for arcing edges on selectors and reversing switch blades.
CuW75 and CuW80 are used as contact materials under extreme arcing conditions.
Applications include arcing contacts in gas and oil circuit
breakers, contactors and transformer tap changers, arcing plates
and arc runners in power switching equipment.
CuW85 and CuW90 have the highest Tungsten content. They are used as contact
materials where resistance to contact welding, sticking and arc
erosion are critical. They also provide satisfactory heat and
current interruption capabilities. Typical applications are power
vacuum switches and high power spark gap electrodes, etc
