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
