Product Description

Main Purpose：
　It is mainly used in high voltage circuit breakers and arc contact for medium-and-high voltage type of charge switches,and the key contactof oil switches.
Contact Properties：
　It is similar to AgW in properties.It won't be oxidized in the oil,with a large amount of heat capacity ,excellent anti-erosion of the arc and well welding resis-tivity and good ability for chipping proceseing.But it is easier to be oxidized than AgW and enlarges the contact resisticity swiftly .When break in the air,it only used on such occasion that it performs on the arc-effected swichesand the str-ong acceptance of the machines but without the flowing of the continuous current.
