AgCdO15 electrical contacts for high voltage appliances such as
breaker, creepage switch
Alloy Material Inner Oxidized is widely used method to make
Oxidized Electrical ,including AgSnO2
,AgSnO2InO3,AgZnO2,AgCu0,AgCd0,etc.
1. Oxidized contact characteristics are as follows:
1,Inner Oxidized Electrical Contact owns excellent consistency
,tiny Oxidized material particle ,arc corrosion resistance and long
electricity life .
2,Adding nickel and thulium to
AgSnO2,AgSn02In2O3,AgZn02,AgCu0,AgCd0,etc with the technology of
low temperature high pressure oxidized takes effect on making grain
tiny ,dispersion and aggrandizement ,consequently improves their
mechanical strength ,ameliorate fusion ,arc corrosion resistance
and abrasion.
3 ,Adopting melting pulverization and pre-oxidized manufacturing
methods can make high quality contact material with the advantage
of grain thin and organization uniformity ,no defection in
microcosmic structure ,eliminating oxide leanness area.
2. The material ingredient and mechanical performance of oxidized
contact

3. main application
Inner Oxidized Electrical Contact are widely used in low voltage
electrical appliance
1, AgSnO2,AgSnO2In03series : Widely used in AC Contactor
(CJ20,CJ40,3TF ,ETC)Power AC Switch (>=50KW),DC Contactor ,AC DC
Power Relay ,Automobile and low voltage circuit breaker.
2, AgSnO2 series: Widely used in low voltage circuit breaker with
rating ,electricity within 200A(such as DZ15 series ,especially
omnipotence breaker )drive socket, protective socket, AC Relay DZ5L
series breaker etc. Some large capacity switches also use AgZnO
materials such as ME omnipotence breaker.
The manufacturing and test equipments for Inner Oxidized Electrical
Contact include intermediate frequency melting furnace, hot mill
and precision mill machine ,auto-stamping machine ,Ionic
Contamination Test System AASWF10,Colored Microscope From Japan
,etc .We can develop and manufacture oxidized contact according to
customers' specific requirement ,and the output can surpass 120
tons annually.
