4-Prevent oxidized when exposure to the air
5-Less and even electrolytic corrosion
Alloy oxide contact products are widely used in low-voltage electrical appliances, and the Welding Electrical Contact main uses are:
1-Silver tin oxide series Resistance welding Contacts:
The Brazing Electrical Contacts are suitable for medium and large capacity AC contactors (such as CJ20, CJ40, 3TF series, etc.), high-power AC switches (above 50kW), DC contactors, AC and DC power relays, and automotive electrical appliances And on the low-voltage circuit breaker of small and medium capacity.
2-Silver zinc oxide series Silver Contact Welding:
Electrical Contact Welding are mainly used in small and medium capacity low voltage circuit breakers with rated current within 200A (such as DZ15 series molded case circuit breakers, especially universal circuit breakers), as well as power protection switches, leakage protection switches, AC relays, DZ15L series leakage current Circuit breakers, etc., some large-capacity switches also use AgZnO materials Contacts Metals Welding, such as ME universal circuit breakers.
3-Silver cadmium oxide series Welded Electrical Contact:
The Welded Contacts widely used in medium and large capacity relays, contactors, AC and DC switches and medium and small capacity circuit breakers, especially suitable for medium and large capacity AC contactors. For the production of silver metal oxide contact products Contact Welding, the existing production of intermediate frequency melting furnaces, hot rolling mills, finishing mills, automatic stamping machines, oxidation furnaces, isostatic presses, extruders, atomic absorption spectrometers, metallographic microscopes, etc., 150 sets of testing equipment can be developed and produced according to the specific requirements of users, with an annual production capacity of 320 tons.
According to the weak electric contact theory, the Silver Contact Welding resistance of Welding Component is composed of shrinkage resistance and surface film resistance. The shrinkage resistance depends on the resistivity of the material itself and the contact area. According to calculations, the shrinkage resistance is inversely proportional to the number of Welded Silver Contact Tips surfaces, that is, the more the number of Welded Electrical Contact surfaces, the larger the area, and the smaller the shrinkage resistance value. The surface film resistance is related to the surface state of the Brazing Silver Contacts to Copper Bars. When the Resistance welding Contacts pressure is small, the membrane resistance dominates, and when the pressure is high, the beam resistance is dominant.
