Eminyakeni edlule, ingxoxo yokuthuthukiswa kokusebenza kanye nohlu lokusetshenziswa kwezintambo ze-aluminium ezigqoke ithusi azikaze ziphazamiseke, futhi isizathu sokuthi kungani izintambo ze-aluminium ezigqoke ithusi bezikhathazeke kakhulu ngemboni kuhlobene ngokwemvelo nenani eliphezulu lezinto zokusetshenziswa. - ithusi;Ngakolunye uhlangothi, ukukhulisa ucwaningo nentuthuko kanye nokwenza ngcono ukusebenza kwezintambo ze-aluminiyamu ezigqoke ithusi kungabuye kukhuthaze ukuthuthukiswa kwemboni yezintambo nezintambo zaseChina ngomqondo othile, futhi kunokubaluleka okuthile okungokoqobo emabhizinisini.Ngakho-ke, naphezu komkhuba wezintambo ze-aluminium ezigqoke ithusi iminyaka eminingi, kuze kube namuhla, ngisho nalapho intambo ye-aluminium exutshwe ne-alloy inyakaziswa kakhulu, ingxoxo yezintambo ze-aluminium ezigqoke ithusi iye yaqhubeka.
Ikhebula lihlukaniswa ngokwama-conductor angaphakathi ahlukene, kunezinhlobo ezimbili eziyinhloko, enye i-copper ehlanzekile, enye i-copper-clad aluminium material.Igama lesiNgisi elisho i-Copper-clad Aluminium lithi: I-Copper Clad Aluminium, ngakho-ke amakhondaktha e-aluminium ane-copper-clad nawo avame ukubizwa ngokuthi: amakhondaktha e-CCA.I-Copper-clad aluminium composite wire yethulwa okokuqala yiJalimane ngeminyaka yawo-1930, yabe isithuthukiswa e-United Kingdom, e-United States, eFrance nakwamanye amazwe, futhi isetshenziswa kakhulu emikhakheni ehlukahlukene.Ikhebula le-CATV e-United States laqala ukuhlola i-copper-clad aluminium wire kusukela ngo-1968, futhi inani elisetshenziswayo lafinyelela kumathani angu-30,000 ngonyaka.Manje amazwe aseMelika athathe indawo yezintambo zethusi ezihlanzekile afaka izintambo ze-aluminium (zensimbi) ezigqize ngethusi.Eminyakeni yamuva nje, ikhebula le-CATV eligqoke ithusi laseChina nalo seliqalile ukusetshenziswa kabanzi.Ngo-2000, umbuso wakha izinga lembonini -SJ/T11223-2000, futhi wakhuthaza ngamandla ukusetshenziswa kwezintambo ze-aluminium ezigqoke ithusi.Njengamanje, iziteshi ze-cable TV e-Shanghai, e-Guangzhou, e-Zhejiang, e-Liaoning nakwezinye izindawo ngokuvamile sezithathe izintambo ze-aluminium ezigqize ngethusi, futhi impendulo yinhle.
I-aluminiyamu egqoke ithusi iyisendlalelo sethusi esinamekwe ngokugxile endaweni ye-aluminium noma i-aluminium/insimbi eyingxubevange yensimbi, eyenziwe ngomdwebo, futhi ukujiya kongqimba lwethusi kungaphezu kuka-0.55mm.Ngenxa yezimpawu zomphumela wesikhumba wokudluliswa kwesignali yemvamisa ephezulu ku-conductor, isignali ye-TV yekhebula idluliselwa ebusweni bongqimba lwethusi ngaphezu kuka-0.008mm, futhi umqhubi wangaphakathi we-aluminium ogqoke ithusi angahlangabezana ngokugcwele nezidingo zokudlulisa isignali, nezici zokudlulisa isignali zihambisana nomzimba wethusi wobubanzi obufanayo.
Ngakho-ke yimuphi umehluko phakathi kwezintambo ze-aluminiyamu ezigqoke ithusi nezintambo zethusi ezihlanzekile ngokusebenza, yiziphi izinzuzo futhi yiziphi amaphutha?Okokuqala, mayelana nezakhiwo zemishini, amandla kanye nokwelulwa kwamakhondaktha ethusi ahlanzekile kukhulu kunamakhondatha e-aluminium ane-copper-clad, okusho ukuthi ithusi elihlanzekile lingcono kune-aluminium egqoke ithusi ngokwezakhiwo zemishini.Ngokombono wokuklama ikhebula, izinzuzo zamandla amahle emishini yamakhondaktha ethusi ahlanzekile kunamakhondatha e-aluminium enziwe ngethusi awadingeki ekusebenzeni okungokoqobo.Ikhondatha ye-aluminium egqoke ithusi ilula kakhulu kunethusi elimsulwa, ngakho-ke isisindo sisonke sekhebula ye-aluminium egqoke ithusi silula kunekhebula elimsulwa lekhondatha yethusi, elizoletha lula ukuthuthwa kwentambo nokumiswa nokwakhiwa kwentambo.Ngaphezu kwalokho, i-aluminium egqoke ithusi ithambile kancane kunethusi elihlanzekile, futhi izintambo ezikhiqizwa ngamakhondatha e-aluminium ane-copper-clad zingcono kunezintambo zethusi ezihlanzekile ngokuthambile.
Okwesibili, ngokusebenza kukagesi, ngenxa yokuthi ukuqhutshwa kwe-aluminium kubi kakhulu kunethusi, ukumelana kwe-DC kwe-copper-clad aluminium conductor kukhulu kune-conductor yethusi ehlanzekile.Ukuthi lokhu kunomthelela kuncike ikakhulukazi ekutheni ikhebula izosetshenziselwa ukuphakelwa kukagesi, njengokuhlinzeka amandla kusikhulisamandla, uma sisetshenziselwa ukuphakelwa kukagesi, ikhondukta ye-aluminium egqoke ithusi izoholela ekusetshenzisweni kwamandla okwengeziwe kanye nogesi kuncishiswe kakhulu.Uma imvamisa idlula i-5MHz, ukuncishiswa kokumelana kwe-AC ngalesi sikhathi akuhlukile kakhulu ngaphansi kwamakhondaktha amabili ahlukene.Yiqiniso, lokhu ikakhulukazi ngenxa yomphumela wesikhumba we-high frequency current, ukuphakama kwemvamisa ephezulu, ukusondela kokugeleza kwamanje kuya ebusweni bomqhubi, ingaphezulu le-copper-clad aluminium conductor empeleni liyimpahla yethusi ehlanzekile, lapho imvamisa iphakeme ukuya endaweni ethile, yonke yamanje ifakwe ezintweni zethusi ngaphakathi kokugeleza.Ku-5MHz, okwamanje kugeleza ngogqinsi olungaba ngu-0.025 mm eduze nendawo, kuyilapho ungqimba lwethusi lwekhondatha ye-aluminium egqoke ithusi lucishe luphindwe kabili.Ezintamboni ze-coaxial, ngenxa yokuthi isignali edlulisiwe ingaphezulu kuka-5MHz, umphumela wokudlulisela wamakhondaktha we-aluminium agqoke ithusi namakhondaktha ethusi ahlanzekile kuyafana.Ukuncishiswa kwekhebula ekuhlolweni kwangempela kungakufakazela lokhu.
Okwesithathu, kusukela esicini sezomnotho, abaqhubi be-aluminium abagqoke ithusi bathengiswa ngesisindo, futhi ama-conductor ethusi ahlanzekile nawo athengiswa ngesisindo, futhi intengo yamakhondaktha e-aluminium egqoke ithusi ibiza kakhulu kunezikhonduki zethusi ezihlanzekile zesisindo esifanayo.Kodwa-ke, isisindo esifanayo se-aluminium egqoke ithusi side kakhulu kunobude be-conductor yethusi ehlanzekile, futhi ikhebula libalwa ngobude.Isisindo esifanayo sentambo ye-aluminiyamu egqoke ithusi iphindwe izikhathi ezingu-2.5 ubude bentambo yethusi, futhi intengo ingama-yuan angamakhulu ambalwa ngaphezulu ngethani.Ihlanganiswe ndawonye, i-aluminium egqoke ithusi inezinzuzo eziningi.Ngenxa yokuthi ikhebula le-aluminium eline-copper-clad lilula, izindleko zokuthutha kanye nezindleko zokufakwa kwekhebula zizoncishiswa, okuzoletha ukunethezeka okuthile ekwakhiweni.
Ngaphezu kwalokho, izintambo ze-aluminium ezigqoke ithusi kulula ukuzinakekela futhi zinezindleko eziphansi zokunakekela kunezintambo zethusi ezimsulwa.Ukusetshenziswa kwe-aluminium egqoke ithusi kunganciphisa ukwehluleka kwenethiwekhi futhi kugweme izisebenzi zenethiwekhi "ekugawulweni okuyisisekelo ebusika nokusika isikhumba ehlobo" ngesikhathi sokulungiswa (iphakheji ye-aluminium strip longitudinal noma imikhiqizo ye-aluminium tube).Ngenxa yomehluko omkhulu ku-coefficient yokwandisa okushisayo phakathi komqhubi wangaphakathi wethusi kanye ne-aluminium yangaphandle yekhebula, ehlobo elishisayo, umqhubi wangaphandle we-aluminium uzokhula kakhulu, futhi umqhubi wangaphakathi wethusi uzoncipha ngokuqhathaniswa futhi akakwazi ukuxhumana ngokugcwele nokuxhumana okunwebekayo. ipuleti esihlalweni se-F-head.Ebusika obubandayo, umqhubi we-aluminium wangaphandle ushwabana kakhulu, okwenza ungqimba oluvikelayo liwe.Lapho i-copper clad aluminium yangaphakathi i-coaxial conductor isetshenziswa kukhebula le-coaxial, i-coefficient yokwandisa ukushisa okushisayo phakathi kwayo kanye nomqhubi wangaphandle we-aluminium incane, iphutha lokudonsa i-cable core-donsa liyancipha kakhulu lapho izinga lokushisa lishintsha, futhi izinga lokudlulisela lenethiwekhi liyathuthukiswa.
Imboni yocingo nekhebula isebenzisa ucingo lwe-aluminium olumbozwe ngethusi kuyindlela enhle yokunciphisa ukucindezela kwamanje kwebhizinisi, ucingo lwe-bimetallic olwenziwe ngongqimba lwethusi ngaphandle kocingo lwe-aluminium, ngenxa yengxenye yalo encane, ukusebenza kahle kokudlulisela kanye nezinye izinzuzo. , elungele ikakhulukazi ukwenza ikhondukta yangaphakathi ye-RF coaxial cable, uma iqhathaniswa nentambo yethusi emsulwa, ukuminyana kwayo cishe kungama-40% wethusi elimsulwa.Izici zokudlulisela zingcono kunocingo lwethusi olumsulwa, okuyi-RF ekahle kakhulu intambo yegatsha lentambo yentambo ye-coaxial.
Ukuthuthukiswa kwemikhiqizo yamakhebula e-aluminium egqoke ithusi esikhathini esizayo kusadinga yonke imboni yocingo nekhebula, kanye namabhizinisi okukhiqiza ukukhuthaza isicelo ngemizamo yokuthuthukisa ukusebenza nokwazisa ulwazi oluhlobene nomkhiqizo, ukuze kube neqhaza ekuqiniseni Imboni yamakhebula yaseChina.
