"Contact is one of the key components of switch electrical appliances, switch electrical appliances, the main performance and the length of life, to a large extent depends on the stand or fall of contact materials. Contact material generally requires good electrical conductivity, low contact resistance, high fusion welding resistance, higher arc erosion resistance and the ability to resist material transfer, for vacuum contactor material, also calls for the closure of small, high crushing strength and high breaking capacity. Contact materials microstructure has important effect on macroscopic properties, electric properties of contact materials such as resistance to dissolve welding, arc ablation resistance and compression capacity is related not only contact materials and composition of ingredients, but also related to the size of the grain size and composition of materials.
AgCdO contact material is a kind of multi-purpose contactor material, because it has the electric arc resistance, flame resistance welding, electrical and mechanical wear resistance, corrosion resistance and is stable and low contact resistance and good processability and weldability, etc can meet the requirements of low voltage electrical contact materials for various, thus has been widely used. AgCdO contact is mainly used in various types of ac contactor, Relä, belysningsomkopplare, kretsskyddsomkopplare, felströmmen i omkopplaren och hjälpbrytaren, kan också användas i den elektriska utrustningen, såsom en del av den gjutna fallbrytaren, det applicerade strömområdet från några till tusentals ANN, ANN kallas "universell kontakt"
