Intambo ye-aluminium embozwe ngethusi yakhiwa ngokumboza ungqimba lwethusi phezu kobuso be-aluminium core, kanti ubukhulu bengqimba yethusi ngokuvamile bungaphezu kuka-0.55mm. Ngenxa yokuthi ukudluliswa kwezibonakaliso zemvamisa ephezulu kumqhubi kunezici zomphumela wesikhumba, isignali ye-TV yekhebula idluliselwa ebusweni bengqimba yethusi engaphezu kuka-0.008mm, kanti umqhubi wangaphakathi we-aluminium embozwe ngethusi angahlangabezana ngokugcwele nezidingo zokudluliswa kwesignali.
1. Izakhiwo zemishini
Amandla nobude bama-conductor ethusi ahlanzekile kukhulu kunokwaba-conductor be-aluminium abambozwe ngethusi, okusho ukuthi izintambo zethusi ezihlanzekile zingcono kunezintambo ze-aluminium ezimbozwe ngethusi ngokwezakhiwo zemishini. Ngokombono wokuklama ikhebula, ama-conductor ethusi ahlanzekile anezinzuzo zamandla emishini angcono kunaba-conductor be-aluminium abambozwe ngethusi.
, okungadingeki ngempela ekusetshenzisweni okungokoqobo. Umqhubi we-aluminium ombozwe ngethusi ulula kakhulu kunethusi elimsulwa, ngakho-ke isisindo sonke sekhebula le-aluminium elimbozwe ngethusi silula kunelekhebula lomqhubi wethusi elimsulwa, okuzokwenza kube lula ukuthuthwa nokwakhiwa kwekhebula. Ngaphezu kwalokho, i-aluminium embozwe ngethusi ithambile kunethusi elimsulwa, futhi izintambo ezikhiqizwa ngama-conductor e-aluminium ambozwe ngethusi zingcono kunezintambo zethusi elimsulwa ngokwemibandela yokuguquguquka.
II. Izici kanye Nezinhlelo Zokusebenza
Ukumelana Nomlilo: Ngenxa yokuba khona kwesigxobo sensimbi, izintambo ze-optical zangaphandle zibonisa ukumelana okuhle kakhulu nomlilo. Izinto zensimbi zingamelana namazinga okushisa aphezulu futhi zihlukanise amalangabi ngempumelelo, zinciphise umthelela womlilo ezinhlelweni zokuxhumana.
Ukudluliselwa Kwebanga Elide: Ngokuvikelwa okubonakalayo okuthuthukisiwe kanye nokumelana nokuphazamiseka, izintambo ze-optical zangaphandle zingasekela ukudluliselwa kwesignali ye-optical ebanga elide. Lokhu kuzenza zibe usizo kakhulu ezimweni ezidinga ukudluliselwa kwedatha okubanzi.
Ukuphepha Okuphezulu: Izintambo ze-optical zangaphandle zingamelana nokuhlaselwa ngokomzimba kanye nomonakalo wangaphandle. Ngakho-ke, zisetshenziswa kabanzi ezindaweni ezinezidingo zokuphepha kwenethiwekhi eziphezulu, njengezisekelo zempi kanye nezikhungo zikahulumeni, ukuqinisekisa ukuphepha nokuthembeka kwenethiwekhi.
2. Izakhiwo zikagesi
Ngenxa yokuthi ukuhanjiswa kwe-aluminium kubi kakhulu kunokwethusi, ukumelana kwe-DC kwabaqhubi be-aluminium abambozwe ngethusi kukhulu kunokwabaqhubi be-copper abamsulwa. Ukuthi lokhu kuthinta ikhebula kuncike kakhulu ekutheni ikhebula lizosetshenziselwa yini ukunikezwa kwamandla, njengokunikezwa kwamandla kwama-amplifier. Uma lisetshenziselwa ukunikezwa kwamandla, umqhubi we-aluminium ombozwe ngethusi uzobangela ukusetshenziswa kwamandla okwengeziwe futhi i-voltage izokwehla kakhulu. Lapho imvamisa idlula i-5MHz, ukuncishiswa kokumelana kwe-AC ngalesi sikhathi akunawo umehluko ocacile ngaphansi kwalaba baqhubi ababili abahlukene. Vele, lokhu kungenxa yomphumela wesikhumba womsinga wemvamisa ephezulu. Uma imvamisa iphakeme, kulapho umsinga ugeleza khona eduze kobuso bomqhubi. Lapho imvamisa ifinyelela ezingeni elithile, umsinga wonke ugeleza ezintweni zethusi. Ku-5MHz, umsinga ugeleza ngobukhulu obungaba ngu-0.025mm eduze kobuso, kanti ubukhulu bengqimba yethusi yomqhubi we-aluminium ombozwe ngethusi buphindwe kabili lobu bukhulu. Kumakhebula e-coaxial, ngoba isignali edlulisiwe ingaphezu kwe-5MHz, umphumela wokudluliselwa kwabaqhubi be-aluminium abambozwe ngethusi kanye nabaqhubi bethusi abamsulwa uyafana. Lokhu kungafakazelwa ukuncishiswa kwekhebula lokuhlola langempela. I-aluminium embozwe ngethusi ithambile kuneziqhubi zethusi ezihlanzekile, futhi kulula ukuyiqondisa enqubweni yokukhiqiza. Ngakho-ke, ngezinga elithile, kungashiwo ukuthi inkomba yokulahlekelwa ukubuya kwezintambo ezisebenzisa i-aluminium embozwe ngethusi ingcono kuneyezintambo ezisebenzisa iziqhubi zethusi ezihlanzekile.
3. Okongayo
Ama-conductor e-aluminium ambozwe ngethusi athengiswa ngesisindo, njengoba kunjalo nangabaqhubi bethusi abamsulwa, kanti ama-conductor e-aluminium ambozwe ngethusi abiza kakhulu kunabaqhubi bethusi abamsulwa abanesisindo esifanayo. Kodwa i-aluminium embozwe ngethusi enesisindo esifanayo inde kakhulu kunomqhubi wethusi omsulwa, futhi ikhebula libalwa ngobude. Isisindo esifanayo, intambo ye-aluminium embozwe ngethusi iphindwe izikhathi ezingu-2.5 kunobude bentambo yethusi emsulwa, intengo ingaphezu ngama-yuan ambalwa ngethani. Uma kuhlanganiswa, i-aluminium embozwe ngethusi inenzuzo enkulu. Ngenxa yokuthi ikhebula le-aluminium elimbozwe ngethusi lilula kakhulu, izindleko zokuhamba kanye nokufakwa kwekhebula kuzoncishiswa, okuzoletha ukulula okuthile ekwakhiweni.
4. Kulula ukunakekela
Ukusetshenziswa kwe-aluminium embozwe ngethusi kunganciphisa ukwehluleka kwenethiwekhi futhi kugweme imikhiqizo yekhebula le-coaxial eligoqwe nge-aluminium noma i-aluminium tube. Ngenxa yomehluko omkhulu ku-coefficient yokwandisa ukushisa phakathi komqhubi wangaphakathi wethusi kanye nomqhubi wangaphandle we-aluminium wekhebula, umqhubi wangaphandle we-aluminium welula kakhulu ehlobo elishisayo, umqhubi wangaphakathi wethusi uhlehlisiwe kancane futhi awukwazi ukuxhumana ngokuphelele nengxenye yokuxhumana enwebekayo esihlalweni sekhanda se-F; ebusika obubandayo kakhulu, umqhubi wangaphandle we-aluminium uyancipha kakhulu, okwenza ungqimba lokuvikela luwe. Lapho ikhebula le-coaxial lisebenzisa umqhubi wangaphakathi we-aluminium embozwe ngethusi, umehluko ku-coefficient yokukhulisa ukushisa phakathi kwalo nomqhubi wangaphandle we-aluminium mncane. Lapho izinga lokushisa lishintsha, iphutha le-core yekhebula liyancipha kakhulu, futhi ikhwalithi yokudlulisela yenethiwekhi iyathuthuka.
Okungenhla umehluko wokusebenza phakathi kwentambo ye-aluminiyamu embozwe ngethusi kanye nentambo yethusi emsulwa
