Intambo ye-aluminiyamu eboshwe ngethusi yenziwa ngokugxilisa ungqimba lwethusi ebusweni bomgogodla we-aluminium, futhi ukujiya kongqimba lwethusi ngokuvamile kungaphezu kuka-0.55mm. Ngenxa yokuthi ukudluliswa kwamasignali emvamisa ephezulu ku-conductor kunezici zomphumela wesikhumba, isignali ye-TV yekhebula idluliselwa phezu kongqimba lwethusi ngaphezu kuka-0.008mm, futhi umqhubi wangaphakathi we-aluminium ogqoke ithusi angahlangabezana ngokugcwele nezidingo zokudlulisa isignali. .
1. Izakhiwo zemishini
Amandla nokwelulwa kwamakhondaktha ethusi ahlanzekile kukhulu kunamakhondaktha e-aluminium agqoke ithusi, okusho ukuthi izintambo zethusi ezimsulwa zingcono kunezintambo ze-aluminiyamu ezigqoke ithusi ngokwezakhiwo zemishini. Ngokombono wokuklanywa kwekhebula, amakhondaktha wethusi amsulwa anezinzuzo zamandla angcono wemishini kunamakhondaktha e-aluminium ane-copper-clad.
, okungadingeki ekusebenzeni okungokoqobo. I-copper-clad aluminium conductor ilula kakhulu kunethusi elimsulwa, ngakho-ke isisindo sisonke sekhebula le-aluminium ene-copper-clad ilula kunekhebula le-copper conductor yethusi, elizoletha ukunethezeka ekuthuthweni nasekwakheni ikhebula. Ngaphezu kwalokho, i-aluminium egqoke ithusi ithambile kunethusi elihlanzekile, futhi izintambo ezikhiqizwa ngamakhondatha e-aluminium ane-copper-clad zingcono kunezintambo zethusi ezihlanzekile mayelana nokuguquguquka.
II. Izici kanye nezicelo
Ukumelana Nomlilo: Ngenxa yokuba khona kweshethi yensimbi, izintambo ezibonakalayo zangaphandle zibonisa ukumelana nomlilo okuhle kakhulu. Izinto zensimbi zingakwazi ukumelana namazinga okushisa aphezulu futhi zihlukanise ngempumelelo amalangabi, zinciphise umthelela womlilo ezinhlelweni zokuxhumana.
Ukudluliswa Kwebanga Elide: Ngokuvikeleka okuthuthukisiwe ngokomzimba kanye nokumelana nokuphazamiseka, amakhebuli okubona angaphandle angasekela ukudluliswa kwesignali yebanga elide. Lokhu kubenza basebenziseke kakhulu ezimeni ezidinga ukudluliswa kwedatha okubanzi.
Ukuvikeleka Okuphezulu: Izintambo ezibonakalayo zangaphandle zingamelana nokuhlaselwa ngokomzimba nokulimala kwangaphandle. Ngakho-ke, asetshenziswa kabanzi ezindaweni ezinezidingo zokuphepha eziphezulu zenethiwekhi, njengezisekelo zamasosha nezikhungo zikahulumeni, ukuqinisekisa ukuphepha nokuthembeka kwenethiwekhi.
2. Izakhiwo zikagesi
Ngenxa yokuthi ukuqhutshwa kwe-aluminium kubi kakhulu kunokwethusi, ukumelana kwe-DC kwamakhondaktha e-aluminium e-copper-clad kukhulu kunamakhondaktha ahlanzekile ethusi. Ukuthi lokhu kuthinta ikhebuli ngokuyinhloko kuncike ekutheni ikhebuli izosetshenziselwa yini ukunikezwa kwamandla, njengokuphakelwa kwamandla ezikhulisi. Uma isetshenziselwa ukunikezwa kwamandla, i-copper-clad aluminium conductor izodala ukusetshenziswa kwamandla okwengeziwe futhi i-voltage izokwehla kakhulu. Lapho i-frequency idlula i-5MHz, ukuncishiswa kokumelana kwe-AC ngalesi sikhathi akunawo umehluko osobala ngaphansi kwalaba baqhubi ababili abahlukene. Yiqiniso, lokhu ikakhulukazi ngenxa yomphumela wesikhumba we-high-frequency current. Ukuphakama kwemvamisa, kusondele ukugeleza kwamanje ebusweni bomqhubi. Lapho imvamisa ifinyelela ezingeni elithile, wonke wamanje ugeleza ezintweni zethusi. Ku-5MHz, okwamanje kugeleza ngogqinsi olucishe lube ngu-0.025mm eduze nendawo, futhi ugqinsi longqimba lwethusi lwekhondatha ye-aluminium egqoke ithusi lucishe luphindeke kabili lobugqinsi. Ezintamboni ze-coaxial, ngenxa yokuthi isignali edlulisiwe ingaphezulu kuka-5MHz, umphumela wokudlulisela wamakhondaktha we-aluminium agqoke ithusi namakhondaktha ethusi ahlanzekile kuyafana. Lokhu kungafakazelwa ngokuncishiswa kwekhebula lokuhlola langempela. I-aluminium ene-Copper-clad ithambile kune-conductor yethusi ehlanzekile, futhi kulula ukuyiqondisa ekukhiqizeni. Ngakho-ke, ngezinga elithile, kungashiwo ukuthi inkomba yokulahlekelwa okubuyayo kwezintambo ezisebenzisa i-aluminium ye-copper-clad ingcono kunezintambo ezisebenzisa ama-conductor ethusi ahlanzekile.
3. Ezomnotho
Amakhondaktha e-aluminium agqoke ithusi athengiswa ngesisindo, njengamakhondaktha ethusi ahlanzekile, futhi amakhondaktha e-aluminium ane-copper-clad abiza kakhulu kunamakhondaktha ethusi amsulwa anesisindo esifanayo. Kodwa i-aluminium ene-copper-clad yesisindo esifanayo yinde kakhulu kunomqhubi wethusi ohlanzekile, futhi ikhebula libalwa ngobude. Isisindo esifanayo, izintambo ze-aluminium ezigqoke ithusi ziphindwe izikhathi ezingu-2.5 ubude bocingo lwethusi oluhlanzekile, intengo ingaphezu kwamayuan angamakhulu ambalwa ngethani. Ihlanganiswe ndawonye, i-aluminium ehlanganiswe ngethusi inenzuzo kakhulu. Ngenxa yokuthi ikhebula le-aluminium eline-copper-clad lilula, izindleko zokuthutha kanye nezindleko zokufakwa kwekhebula zizoncishiswa, okuzoletha ukunethezeka okuthile ekwakhiweni.
4. Ukugcinwa kalula
Ukusetshenziswa kwe-aluminium egqoke ithusi kunganciphisa ukwehluleka kwenethiwekhi futhi kugweme itheyipu ye-aluminium esongwe ngobude noma imikhiqizo yekhebula le-aluminium tube coaxial. Ngenxa yomehluko omkhulu ku-coefficient yokwandisa okushisayo phakathi kwe-copper yangaphakathi yethusi kanye ne-aluminium yangaphandle conductor yekhebula, ikhondukta yangaphandle ye-aluminium inwebeka kakhulu ehlobo elishisayo, i-conductor yangaphakathi yethusi ihlehla ngokuqhathaniswa futhi ayikwazi ukuxhumana ngokugcwele nocezu lokuxhumana olunwebekayo. F isihlalo sekhanda; ebusika obubanda kakhulu, ikhondakta yangaphandle ye-aluminium ishwabana kakhulu, okwenza ungqimba oluyisivikelo liwe. Uma ikhebuli ye-coaxial isebenzisa i-copper-clad aluminium conductor yangaphakathi, umehluko ku-thermal coefficient yokwandisa phakathi kwayo ne-aluminium yangaphandle yekhondatha mncane. Lapho izinga lokushisa lishintsha, iphutha le-cable core liyancipha kakhulu, futhi ikhwalithi yokudlulisela yenethiwekhi iyathuthukiswa.
Okungenhla umehluko wokusebenza phakathi kwe-copper-clad aluminium wire kanye ne- pure copper wire
