Alloy 180 Manganin Insulated Enameled Copper Nickel CuNi Resistance Wire
Round Copper Yakavakirwa NicrAlloy 180dhigirii Kirasi Insulated Enameled Copper Wire
1.Material General Tsanangudzo
1)
Manganinialloy inowanzoita 84% mhangura, 12% manganese, uye 4% nickel.
Manganin waya uye foil inoshandiswa mukugadzira maresitorendi, especially ammeter shunt, nekuda kweayo angangoita zero tembiricha coefficient yekupikisa uye kugadzikana kwenguva refu.Several Manganin resistors yakashanda semutemo we ohm muUnited States kubva muna 1901 kusvika muna 1990. Manganin wire inoshandiswawo semugadziri wemagetsi mu cryogenic systems, kuderedza kupisa kwekushisa pakati penzvimbo dzinoda kubatanidza magetsi.
Manganin inoshandiswawo mumageji ezvidzidzo zvemafungu e-high-pressure shock (seaya anogadzirwa kubva pakuputika kwezvinoputika) nekuti ine low strain sensitivity asi yakakwira hydrostatic pressure sensitivity.
2)
Constantanimhangura-nickel alloy inozivikanwawo seEureka, Advance,uyeFerry.Kazhinji ine 55% mhangura uye 45% nickel.Chinhu chayo chikuru ndechekudzivirira kwayo, iyo inogara iri pamusoro pehupamhi hwekushisa.Mamwe maaloyi ane akafanana akadzika tembiricha coefficients anozivikanwa, akadai semangan (Cu86Mn12Ni2).
Pakuyerwa kwezvimedu zvakakura kwazvo, 5% (50 000 microstrian) kana pamusoro, annealed constantan (P alloy) ndiyo grid material inowanzosarudzwa.Constantan mune iyi fomu yakanyanya ductile;uye, mukureba kwe 0.125 inches (3.2 mm) uye kureba, inogona kusvetwa kusvika> 20%.Izvo zvinofanirwa kurangarirwa, zvisinei, kuti pasi peyakakwira cyclic dhizaini iyo P alloy inoratidza imwe yekusingaperi resistivity shanduko nekutenderera kwega kwega, uye kukonzera inoenderana zero shanduko mugeji yekunetsa.Nekuda kwehunhu uhu, uye hunhu hwekutadza kwegidhi nguva isati yakwana nekudzokororwa kudzokororwa, P alloy haiwanzo kurudzirwa kune cyclic strain application.P alloy inowanikwa ne STC nhamba dze08 ne 40 dzekushandisa pasimbi nemapurasitiki, zvichiteerana.
2. Enamelled Wire Sumo nemashandisirwo
Kunyangwe ichitsanangurwa se "enameled", enameled waya haina kuputirwa nechero pendi yeenamel kana ne vitreous enamel yakagadzirwa neyakasanganiswa girazi poda.Waya yemazuva ano yemagineti inowanzo shandisa tambo imwe kusvika ina (kana iri quad-firimu mhando waya) yepolymer firimu insulation, kazhinji yemhando mbiri dzakasiyana, kupa yakaoma, inoenderera insulating layer.Magnet waya insulating mafirimu anoshandisa (mukuronga kuwedzera tembiricha siyana) polyvinyl formal (Formar), polyurethane, polyimide, polyamide, polyster, polyester-polyimide, polyamide-polyimide (kana amide-imide), uye polyimide.Polyimide insulated magineti waya inokwanisa kushanda kusvika pa250 °C.Iko kuvharidzirwa kweyakareba sikweya kana rectangular magineti waya inowanzowedzerwa nekuiputira nepamusoro-tembiricha polyimide kana fiberglass tepi, uye kupera kunopera kuvharwa kunowanzo kuvharirwa nevhavha inodzivirira kuvandudza simba rekudzivirira uye kuvimbika kwenguva refu kwemhepo.
Makoiri anozvitsigira anokuvadzwa newaya yakavharwa netumwe twuviri, yekunze iri thermoplastic inobatanidza majoko pamwe chete kana yapiswa.
Mamwe marudzi ekudzivirira senge fiberglass yarn ine varnish, aramid bepa, kraft bepa, mica, uye polyester firimu rinoshandiswawo zvakanyanya pasirese kune akasiyana maapplication sematransformer nemareactor.Muchikamu cheaudio, waya yekuvaka sirivha, uye zvimwe zvakasiyana-siyana zvinodzivirira, zvakaita sedonje (dzimwe nguva zvakanyungudutswa neimwe mhando yecoagulating agent/thickener, senge wakisi) uye polytetrafluoroethylene (PTFE) inogona kuwanikwa.Zvishandiso zvechinyakare zvekudzivirira zvaisanganisira donje, bepa, kana sirika, asi izvi zvinongobatsira pakudzikira-kupisa (kusvika 105°C).
Kuti zvive nyore kugadzira, imwe yakaderera-yegiredhi-giredhi magineti waya ine insulation inogona kubviswa nekupisa kwekutengesa.Izvi zvinoreva kuti magetsi ekubatanidza kumigumo anogona kuitwa pasina kubvisa insulation kutanga.
