Kule minyaka, ingxoxo malunga nokuphucula ukusebenza kunye noluhlu lwesicelo se-copper-clad aluminium cables ayizange iphazamiseke, kwaye isizathu sokuba i-copper-clad aluminium cables ixhalabele kakhulu kwishishini lihambelana ngokwemvelo nexabiso eliphezulu lezinto eziluhlaza. – ubhedu;Kwelinye icala, ukonyusa uphando kunye nophuhliso kunye nokuphuculwa kokusebenza kweentambo zobhedu ezinxibe i-aluminiyam kunokukhuthaza uphuhliso lweshishini laseTshayina locingo kunye nentambo ngendlela ethile, kwaye ibaluleke kakhulu kumashishini.Ngoko ke, nangona kusenziwa iintambo zobhedu ezigqunywe ngobhedu iminyaka emininzi, kude kube namhlanje, naxa intambo ye-aluminiyam ixutywa ngokubanzi, iqhubekile ingxoxo ngeentambo zobhedu ezigqunywe ngobhedu.
Intambo yahlulwe ngokwee-conductors zangaphakathi ezahlukeneyo, zimbini iindidi eziphambili, enye yimathiriyeli yobhedu esulungekileyo, kwaye enye yimathiriyeli yobhedu ene-aluminiyam.Igama lesiNgesi le-copper-clad Aluminium lithi: I-Copper Clad Aluminium, ngoko ke iikhondaktha ze-aluminiyam ene-copper-clad zikwabizwa ngokuba: ii-CCA conductors.I-Copper-clad aluminium composite wire yaqala ukusungulwa yiJamani kwi-1930, kwaye emva koko yakhuthazwa e-United Kingdom, e-United States, eFransi nakwamanye amazwe, kwaye isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo.Ikhebula le-CATV e-United States laqala ukuvavanya ucingo lwe-aluminium e-copper-clad ekuqaleni kwe-1968, kwaye ixabiso lokusetyenziswa lifike kwi-30,000 yeetoni / ngonyaka.Ngoku amazwe akumazwe aseMerika athabathel’ indawo iintambo zobhedu ezisulungekileyo zaza zafaka iintambo zobhedu ezine-aluminium (zentsimbi).Kwiminyaka yakutshanje, intambo ye-CATV ye-CATV ene-copper-clad yase-China sele iqalile ukusetyenziswa ngokubanzi.Kwi-2000, urhulumente waqulunqa umgangatho woshishino -SJ / T11223-2000, kwaye wakhuthaza ngamandla ukusetyenziswa kweentambo ze-aluminium zobhedu.Okwangoku, izikhululo ze-TV ze-cable e-Shanghai, e-Guangzhou, e-Zhejiang, e-Liaoning nakwezinye iindawo ziye zamkela iintambo ze-aluminium ezinobhedu, kwaye impendulo ilungile.
I-aluminium ene-Copper-clad i-copper efakwe kwi-concentrically copper kumphezulu we-aluminium okanye i-aluminium / i-alloy core material, eyenziwa ngokuzoba, kwaye ubukhulu bobhedu bungaphezulu kwe-0.55mm.Ngenxa yeempawu zempembelelo yesikhumba sokuhanjiswa komqondiso we-high-frequency kwi-conductor, i-cable signal ye-TV ihanjiswa phezu kwendawo yobhedu ngaphezu kwe-0.008mm, kunye ne-copper clad aluminium conductor yangaphakathi inokuhlangabezana ngokupheleleyo neemfuno zokuhambisa umqondiso, kunye neempawu zokuhambisa umqondiso zihambelana nomzimba wobhedu wobubanzi obufanayo.
Ngoko ke yintoni umahluko phakathi kweentambo ze-aluminium ezinobhedu kunye neentambo zobhedu ezicocekileyo ngokubhekiselele ekusebenzeni, ziziphi iingenelo kwaye ziziphi iintsilelo?Okokuqala, ngokubhekiselele kwiimpawu zemishini, amandla kunye nokwandiswa kwee-conductor zobhedu ezicocekileyo zikhulu kunezo zikhonduki ze-aluminium ezifakwe ubhedu, oku kuthetha ukuba ubhedu olucocekileyo lungcono kune-aluminiyam yobhedu ngokubhekiselele kwimpahla yomatshini.Ukusuka kwimbono yoyilo lwekhebula, iingenelo zamandla alungileyo omatshini wokuqhuba ubhedu olusulungekileyo kuneziqhubi ze-aluminium ezinxibe ubhedu aziyimfuneko kwizicelo ezisebenzayo.I-copper-clad aluminium conductor ilula kakhulu kunobhedu olusulungekileyo, ngoko ke ubunzima obupheleleyo bentambo ye-aluminium ene-copper-clad ilula kune-copper conductor cable, eya kuzisa lula ukuthuthwa kwentambo kunye nokwakhiwa kunye nokwakhiwa kwentambo.Ukongezelela, i-aluminium ene-copper-clad i-softer encinci kune-copper ecocekileyo, kwaye iintambo eziveliswe nge-copper-clad aluminium conductors zingcono kuneentambo zobhedu ezicocekileyo ngokubhekiselele kwi-softness.
Okwesibini, ngokubhekiselele ekusebenzeni kombane, ngenxa yokuba i-aluminium conductivity imbi kakhulu kunobhedu, ukuchasana kwe-DC ye-copper-clad i-aluminium conductor inkulu kuneyomqhubi wobhedu ococekileyo.Ukuba oku kunempembelelo kuxhomekeke ikakhulu ekubeni intambo iya kusetyenziselwa unikezelo lwamandla, njengokubonelela ngamandla kwi-amplifier, ukuba isetyenziselwa unikezelo lwamandla, umqhubi we-aluminium onxibe ubhedu uya kukhokelela kusetyenziso lwamandla olongezelelweyo kunye nombane kuncitshiswe ngakumbi.Xa i-frequency idlula i-5MHz, ukuthotywa kwe-AC ngeli xesha akwahlukanga kakhulu phantsi kwee-conductor ezimbini ezahlukeneyo.Kakade ke, oku kungenxa yempembelelo yesikhumba ye-high frequency yangoku, ukuphakama kwe-frequency ephezulu, ukusondela kokuhamba kwangoku kumphezulu womqhubi, umphezulu we-copper-clad i-aluminium conductor eneneni yinto ecocekileyo yobhedu, xa i-frequency iphezulu ukuya kwindawo ethile, yonke yangoku ifakwe kwizinto zobhedu ngaphakathi kokuhamba.Kwi-5MHz, i-current flowing in the thick of about 0.025 mm kufuphi nomphezulu, ngelixa ubhedu lwe-copper-clad aluminium conductor malunga nokuphindwe kabini ubukhulu.Kwiintambo ze-coaxial, ngenxa yokuba isignali edlulisiweyo ingaphezulu kwe-5MHz, umphumo wokuhanjiswa kwee-copper-clad aluminium conductors kunye neeconductors ezicocekileyo zobhedu ziyafana.Ukuthotywa kwentambo kuvavanyo lwangempela kunokungqina oku.
Okwesithathu, ukusuka kwinkalo yezoqoqosho, abaqhubi be-aluminium be-copper-clad bathengiswa ngobunzima, kwaye ii-conductors zobhedu ezicocekileyo nazo zithengiswa ngobunzima, kwaye ixabiso le-copper-clad aluminium conductors libiza kakhulu kunezikhokelo zethusi ezicocekileyo ezinobunzima obufanayo.Nangona kunjalo, ubunzima obufanayo be-aluminium ene-copper-clad bude kakhulu kunobude bomqhubi wobhedu ococekileyo, kwaye ikhebula libalwa ngobude.Ubunzima obufanayo bocingo lwe-aluminiyam yobhedu buphindwe ngama-2.5 ubude bocingo lobhedu, kwaye ixabiso lingamakhulu ambalwa e-yuan ngaphezulu kwetoni nganye.Xa zidibene, i-aluminium ene-copper-clad ineenzuzo ezininzi.Ngenxa yokuba intambo ye-aluminium yobhedu ilula, iindleko zokuthutha kunye neendleko zokufakela ikhebula ziya kuncitshiswa, eziza kuzisa ukulungelelaniswa okuthile kulwakhiwo.
Ukongezelela, iintambo ze-aluminiyam ezifakwe ubhedu kulula ukuzigcina kwaye zineendleko eziphantsi zokugcinwa kuneentambo zobhedu ezicocekileyo.Ukusetyenziswa kwe-aluminium yobhedu kunokunciphisa ukungaphumeleli kwenethiwekhi kwaye kugweme abasebenzi benethiwekhi "ukusika ingundoqo ebusika kunye nokusika ulusu ehlobo" ngexesha lokugcinwa (i-aluminium strip longitudinal package okanye iimveliso ze-aluminium tube).Ngenxa yomahluko omkhulu kwi-coefficient yokwandiswa kwe-thermal phakathi komqhubi wangaphakathi wobhedu kunye ne-aluminium yangaphandle yomqhubi wentambo, ehlotyeni eshushu, umqhubi wangaphandle we-aluminium uya kwanda kakhulu, kwaye umqhubi wangaphakathi wobhedu uya kuncipha kwaye akakwazi ukuqhagamshelana ngokupheleleyo noqhagamshelwano olulastiki. ipleyiti kwisihlalo se-F-head.Ebusika obubandayo, umqhubi wangaphandle we-aluminium uyancipha kakhulu, okwenza ukuba i-shielding layer iwele.Xa umqhubi wangaphakathi we-aluminium owenziwe nge-coaxial, i-coaxial coefficient yokwandisa i-thermal phakathi kwayo kunye nomqhubi wangaphandle we-aluminium incinci, iphoso le-cable core-donsa liyancipha kakhulu xa ubushushu buguquka, kwaye umgangatho wokuhanjiswa kwenethiwekhi uphuculwe.
I-wire kunye ne-cable industry usebenzisa ucingo lwe-aluminium olugqunywe ngobhedu lukwayindlela efanelekileyo yokunciphisa uxinzelelo lwangoku lweshishini, ucingo lwe-bimetallic olwenziwa ngumaleko wobhedu ngaphandle kocingo lwe-aluminium, ngenxa yomlinganiselo omncinci, ukusebenza kakuhle kokuhanjiswa kunye nezinye iingenelo. , ifaneleke ngakumbi ukwenza i-coaxial cable yangaphakathi yeRF coaxial cable, xa kuthelekiswa nocingo olusulungekileyo lobhedu, ukuxinana kwayo malunga ne-40% yobhedu olusulungekileyo.Iimpawu zothumelo zingcono kunocingo olusulungekileyo lobhedu, lolona lufanelekileyo lwe-RF coaxial cable yesebe lomqhubi wentambo.
Uphuhliso lwemveliso yentambo yobhedu aluminiyam kwixesha elizayo lusafuna lonke ushishino lwentambo kunye nentambo, kunye namashishini emveliso ukukhuthaza usetyenziso ngeenzame zokuphucula ukusebenza kunye nokwazisa ulwazi olunxulumene nemveliso, ukuze kube negalelo ekomelezeni imveliso. ishishini cable China.
