Ngoku, iteknoloji yonxibelelwano iye yaba yinxalenye eyimfuneko kwiinqanawa zanamhlanje. Ingaba isetyenziselwa ukuhamba, ukunxibelelana, ukuzonwabisa, okanye ezinye iinkqubo ezibalulekileyo, ukuhanjiswa kwesignali ethembekileyo sisiseko sokuqinisekisa ukusebenza ngokukhuselekileyo kunye nokusebenza kakuhle kweenqanawa. Iintambo ze-coaxial zaselwandle, njengendawo yothungelwano ebalulekileyo yonxibelelwano, zidlala indima ebalulekileyo kwiinkqubo zonxibelelwano lweenqanawa ngenxa yesakhiwo sazo esisodwa kunye nokusebenza okugqwesileyo. Eli nqaku liza kunika intshayelelo eneenkcukacha kwisakhiwo se-marine coaxial cables, ejolise ekuncedeni ukuba uqonde ngcono imigaqo yoyilo kunye neenzuzo zesicelo.
Ulwakhiwo olusisiseko Intshayelelo
Umqhubi wangaphakathi
Umqhubi wangaphakathi yinxalenye engundoqo ye-marine coaxial cables, eyona nto inoxanduva lokuhambisa iimpawu. Ukusebenza kwayo kuchaphazela ngokuthe ngqo ukusebenza kunye nomgangatho wokuhanjiswa komqondiso. Kwiinkqubo zonxibelelwano lweenqanawa, i-conductor yangaphakathi ithwala umsebenzi wokudlulisa iimpawu ukusuka kwisixhobo sokuhambisa ukuya kwisixhobo sokufumana, okwenza ukuzinza nokuthembeka kwayo kubaluleke kakhulu.
I-conductor yangaphakathi ngokuqhelekileyo yenziwe nge-high-purity copper. I-Copper inezakhiwo ezigqwesileyo zokuqhuba, iqinisekisa ilahleko encinci yesignali ngexesha lokuhanjiswa. Ukongezelela, ubhedu luneempawu ezintle zoomatshini, nto leyo eyenza ukuba imelane noxinzelelo oluthile lomatshini. Kwezinye izicelo ezikhethekileyo, i-conductor yangaphakathi inokuba yi-copper-plated yesiliva ukuqhubela phambili ukuphucula ukusebenza kwe-conductive. Ubhedu oluxutywe ngesilivere ludibanisa iipropati zokuqhuba ubhedu kunye neempawu eziphantsi zokumelana nesilivere, ukuhambisa ukusebenza okugqwesileyo kwi-high-frequency signal transmission.
Inkqubo yokuvelisa i-conductor yangaphakathi iquka umzobo wocingo lobhedu kunye nonyango lokutya. Umzobo wocingo lobhedu ufuna ulawulo oluchanekileyo lwedayamitha yocingo ukuze kuqinisekiswe ukusebenza komqhubi wangaphakathi. Ukunyangwa kwe-Plating kunokuphucula ukuxhathisa ukubola kunye neempawu zomatshini zomqhubi wangaphakathi. Kwizicelo ezifuna kakhulu, umqhubi wangaphakathi unokusebenzisa itekhnoloji yokufakwa kwemigangatho emininzi ukomeleza ngakumbi ukusebenza. Ngokomzekelo, i-multi-layer plating yobhedu, i-nickel, kunye nesilivere ibonelela nge-conductivity engcono kunye nokumelana nokubola.
Ububanzi kunye nokuma komqhubi wangaphakathi kuchaphazela kakhulu ukusebenza kokuhanjiswa kweentambo ze-coaxial. Kwiintambo ze-coaxial zaselwandle, i-diameter ye-coaxial conductor yangaphakathi idla ngokufuneka iphuculwe ngokusekwe kwiimfuno ezithile zothumelo ukuze kuqinisekiswe usasazo oluzinzileyo kwimekobume yaselwandle. Ngokomzekelo, ukuhanjiswa kwesignali ye-frequency high-frequency kufuna i-conductor yangaphakathi encinci ukunciphisa ukuthotywa kwesignali, ngelixa ukuhanjiswa kwesignali ephantsi-frequency kunokusebenzisa i-conductor yangaphakathi engqindilili ukuphucula amandla omqondiso.
I-Insulation Layer
Uluhlu lwe-insulation lubekwe phakathi komqhubi wangaphakathi kunye nomqhubi wangaphandle. Umsebenzi wayo oyintloko kukuthintela ukuvuza komqondiso kunye neesekethe ezimfutshane, ukwahlula umqhubi wangaphakathi kumqhubi wangaphandle. Izinto eziphathekayo ze-insulation layer kufuneka zibe ne-insulation egqwesileyo yombane kunye neempawu zomatshini ukuqinisekisa ukuzinza kunye nokunyaniseka kweempawu ngexesha lokuhambisa.
Umaleko wokugquma weentambo ze-coaxial zaselwandle kufuneka kwakhona ube nokuxhathisa umhlwa wokutshizwa kwetyuwa ukukhawulelana neemfuno ezikhethekileyo zemo engqongileyo yaselwandle. Izinto eziqhelekileyo zokugquma zibandakanya i-polyethylene ye-foam (i-Foam PE), i-polytetrafluoroethylene (PTFE), i-polyethylene (PE), kunye ne-polypropylene (PP). Ezi zixhobo azinayo kuphela iimpawu ezigqwesileyo zokugquma kodwa zinokumelana nokwahluka kobushushu obuthile kunye nokubola kweekhemikhali.
Ubukhulu, ukufana, kunye nokugxila komgangatho wokugquma kunempembelelo enkulu ekusebenzeni kothumelo lwentambo. Umaleko wokugquma kufuneka ube ngqindilili ngokwaneleyo ukunqanda ukuvuza komqondiso kodwa ungabi ngqindilili ngokugqithisileyo, njengoko oku kunokonyusa ubunzima bekhebula kunye neendleko. Ukongeza, umaleko wokugquma kufuneka ube nokuguquguquka okulungileyo ukulungiselela ukugoba kwentambo kunye nokungcangcazela.
I-Conductor yangaphandle (Uluhlu olukhuselayo)
Umqhubi wangaphandle, okanye umaleko okhuselayo wentambo ye-coaxial, usebenza ngokuyintloko ukukhusela ngokuchasene nokuphazamiseka kwe-electromagnetic yangaphandle, eqinisekisa uzinzo lwesignali ngexesha lothumelo. Uyilo lomqhubi wangaphandle kufuneka luthathele ingqalelo uphazamiseko lwe-anti-electromagnetic kunye nokusebenza okuchasene nokungcangcazela ukuqinisekisa uzinzo lwesignali ngexesha lokuhamba kwenqanawa.
Umqhubi wangaphandle wenziwa ngokwesiqhelo ngocingo olulukiweyo lwentsimbi, olubonelela ngokuguquguquka okugqwesileyo kunye nokusebenza kokukhusela, ukunciphisa ngokufanelekileyo ukuphazamiseka kwe-electromagnetic. Inkqubo yokulukwa komqhubi wangaphandle idinga ulawulo oluchanekileyo lwe-braid density kunye ne-angle ukuqinisekisa ukusebenza kokukhusela. Emva kwe-braiding, umqhubi wangaphandle ufumana unyango lokushisa ukuze aphucule iimpawu zayo zomatshini kunye ne-conductive.
Ukusebenza kokhuselo yimetric ephambili yokuvavanya ukusebenza komqhubi wangaphandle. Uthintelo oluphezulu olukhuselayo lubonisa ukusebenza ngcono kwe-anti-electromagnetic interference. Iintambo ze-coaxial zaselwandle zifuna ukuthotywa okuphezulu kokhuseleko ukuze kuqinisekiswe ukuhanjiswa komqondiso okuzinzileyo kwiindawo ezintsonkothileyo ze-electromagnetic. Ukongeza, umqhubi wangaphandle kufuneka abe nokuguquguquka okuhle kunye neepropathi zokuchasa ukushukuma ukuze aziqhelanise nemeko yomatshini yeenqanawa.
Ukomeleza ukusebenza kophazamiseko lwe-anti-electromagnetic, iintambo ze-coaxial zaselwandle zihlala zisebenzisa izikhuselo eziphindwe kabini okanye eziphindwe kathathu. Ulwakhiwo olukhuselwe kabini lubandakanya umaleko wocingo olulukiweyo lwetsimbi kunye noluhlu lwefoyile ye-aluminium, ukunciphisa ngokufanelekileyo impembelelo yokuphazamiseka kwangaphandle kwe-electromagnetic kwi-transmission signal. Esi sakhiwo sisebenza kakuhle kakhulu kwiimeko ezintsonkothileyo ze-electromagnetic, ezifana neenkqubo zeradar yeenqanawa kunye neenkqubo zonxibelelwano ngesathelayithi.
Isingxobo
I-sheath ngumaleko okhuselayo wentambo ye-coaxial, ekhusela intambo kukhukuliseko lwangaphandle. Kwiintambo ze-coaxial zaselwandle, imathiriyeli ye-sheath kufuneka ibe neempawu ezifana nokuxhathisa ityuwa yokutshiza, ukuxhathisa ukunxitywa, kunye nokubuyiswa komlilo ukuqinisekisa ukuthembeka kunye nokhuseleko kwindawo enzima.
Izinto eziqhelekileyo ze-sheath ziquka i-low-smoke zero-halogen (LSZH) polyolefin, i-polyurethane (PU), i-polyvinyl chloride (PVC), kunye ne-polyethylene (PE). Ezi zixhobo zikhusela ikhebula kukhukuliseko lwangaphandle lokusingqongileyo.
