Relay classified according to the use, must have the automobile relay, communication relay, relay, home machine relay four human, if the contact load classification, mainly has the micro power relay, weak power relays, power relays, power relays in four categories. Relay for electric contactHead material requirements for: excellent electrical conductivity, low and stable contact resistance, good electrical wear resistance and excellent resistance to varjenje . Kontaktni material je ključni material v releju, njegov rele v Sichuanu je: ko nekateri parametri (tok, napetost, temperatura, tlak itd.
Razvojna zgodovina kontaktnih materialov in čiste kovine, kasting podjetij, prašek za trifazni vmesnik podjetja . iz dobre prevodne toplotne prevodnosti čistih podjetij pripada enemu, razvoj zlitine ima dobro prevodno toplotno prevodnost in dobro korozijsko upornost in dobro upornost z varinjem
Agsn02 contact material life and sichuan in Europe has been relatively mature and widely used in contactor, breaker and relay switch 1, and in the aspect of new additives and application is still in development. AgSnO2 contact material of our country's research and development, production and application is still in the primary stage of development, on the one hand, Ann learning art, with mature technology and T another. Ways to combine Dejansko stanje nizkonapetostnih aparatov na Kitajskem je raziskava razvila ustrezna kontaktna gradiva, dala v celoti igro našim raziskovalnim inštitutom, univerzam in podjetjem v njihovih prednosti
