Kwemakore, nhaurirano pamusoro pekuvandudzwa kwekuita uye mashandisirwo emhando yemhangura-akapfeka aluminium tambo haisati yambovhiringwa, uye chikonzero nei tambo dzakapfeka aluminium yemhangura dzave dzichinetsekana neindasitiri iyi zvine chekuita nemutengo wepamusoro wezvigadzirwa. - mhangura;Kune rimwe divi, kuwedzera kutsvagisa nekusimudzira uye kuvandudza mashandiro emhangura-akapfeka aluminium tambo zvinogona zvakare kusimudzira kusimudzira kweChina waya uye tambo indasitiri mune imwe pfungwa, uye zvine zvimwe zvakakosha zvakakosha kumabhizinesi.Nokudaro, pasinei netsika yemhangura-akapfeka tambo dzearuminiyamu kwemakore akawanda, kusvika nhasi, kunyange kana tambo yealuminium alloy ichinyanya kubvongodzwa-yakakangwa, nhaurirano yetambo dzearuminiyamu yemhangura yakaenderera mberi.
Tambo yakakamurwa zvichienderana neakasiyana emukati maconductor, kune maviri makuru marudzi, imwe yakachena yemhangura zvinhu, uye imwe ndeyemhangura-yakapfeka aluminium zvinhu.Shoko rechirungu reCopper-clad Aluminium nderekuti: Copper Clad Aluminium, saka maconductor ecopper-clad aluminium anowanzo kunzi: CCA conductors.Copper-clad aluminium composite waya yakatanga kutangwa neGermany kuma1930, ndokuzosimudzirwa kuUnited Kingdom, United States, France nedzimwe nyika, uye inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana.Iyo CATV tambo muUnited States yakatanga kuyedza copper-clad aluminium waya kutanga muna 1968, uye huwandu hwekushandisa hwakasvika 30,000 matani / gore.Iye zvino nyika dziri muAmerica dzakatsiva tambo dzemhangura dzakachena netambo dzendarira-clad aluminium (simbi).Mumakore achangopfuura, China copper-clad aluminium CATV tambo yakatangawo kushandiswa zvakanyanya.Muna 2000, nyika yakagadzira chiyero cheindastiri -SJ/T11223-2000, uye yakakurudzira zvakasimba kushandiswa kwemhangura-akapfeka tambo dzealuminium.Parizvino, zviteshi zveTV muShanghai, Guangzhou, Zhejiang, Liaoning nedzimwe nzvimbo dzakagara dzichitora tambo dzendarira-clad aluminium, uye mhinduro yacho yakanaka.
Copper-clad aluminium isimbi yakavharidzirwa yemhangura pamusoro pealuminium kana aruminiyamu / simbi alloy core material, iyo inogadzirwa nekudhirowa, uye ukobvu hwemhangura layer iri pamusoro pe0.55mm.Nekuda kwehunhu hwekuita kweganda repamusoro-frequency chiratidzo chekufambisa pane conductor, tambo yeTV chiratidzo inofambiswa pamusoro pemhangura yemhangura pamusoro pe 0.008mm, uye copper yakavharwa aluminium yemukati conductor inogona kuzadzisa zvizere zvinodikanwa zvekutumira chiratidzo, uye zviratidzo zvekutumira zviratidzo zvinopindirana nemuviri wemhangura wedhayamita imwechete.
Saka ndeupi musiyano uripo pakati pemhangura-akapfeka aluminium tambo uye yakachena copper tambo maererano nekuita, ndezvipi zvakanakira uye ndezvipi zvinokanganisa?Chokutanga pane zvose, maererano nemagetsi emagetsi, simba uye kureba kwemhangura yakachena yemhangura yakakura kudarika iyo yemhangura-clad aluminium conductors, zvinoreva kuti mhangura yakachena iri nani pane aluminium yemhangura-yakapfeka maererano nemagetsi.Kubva pakuona kwekugadzirwa kwetambo, zvakanakira simba rakanaka remagetsi emhangura yakachena conductor pane copper clad aluminium conductors hazvidi hazvo kudikanwa mukushandisa zvinoshanda.Copper-clad aluminium conductor yakareruka kupfuura mhangura yakachena, saka huremu hwemhangura-yakapfeka aluminium tambo yakareruka pane yakachena mhangura conductor tambo, izvo zvinounza kuve nyore kutakurwa kwetambo uye erection uye kuvaka tambo.Mukuwedzera, copper-clad aluminium ishoma zvishoma kudarika mhangura yakachena, uye tambo dzakagadzirwa nemhangura-clad aluminium conductors dziri nani kudarika tambo dzemhangura dzakachena maererano nekunyorova.
Chechipiri, maererano nekushanda kwemagetsi, nokuti conductivity yealuminium yakaipisisa kupfuura yemhangura, iyo DC inopikisa yemhangura-clad aluminium conductor yakakura kudarika iyo yakachena yemhangura conductor.Kunyangwe izvi zvine chekuita nazvo zvinoenderana nekuti tambo ichashandiswa kugovera magetsi, sekupa simba kune amplifier, kana ichishandiswa kupa magetsi, iyo copper-clad aluminium conductor inotungamira kune mamwe mashandisirwo emagetsi uye magetsi anozoita. kuderedzwa zvakanyanya.Kana iyo frequency ichipfuura 5MHz, iyo AC kuramba attenuation panguva ino haina kunyanya kusiyana pasi pemakondakita maviri akasiyana.Ehezve, izvi zvinonyanya nekuda kweganda mhedzisiro yakakwira frequency ikozvino, iyo yakakwira frequency, padhuze kuyerera kwazvino kuri pamusoro peiyo conductor, pamusoro pemhangura-yakapfeka aluminium conductor ichokwadi yakachena mhangura zvinhu, apo. iyo frequency yakakwirira kune imwe nzvimbo, iyo yese ikozvino yakaputirwa mumhangura zvinhu mukati mekuyerera.Pa5MHz, yazvino inoyerera muhukobvu hunosvika 0.025 mm padyo nepamusoro, nepo mhangura yemhangura-yakapfeka aluminium conductor ingangoita zvakapetwa kaviri.Kune coaxial tambo, nekuti iyo inofambiswa siginecha iri pamusoro pe5MHz, iyo yekufambisa mhedzisiro yemhangura-yakapfeka aluminium conductors uye yakachena conductor yemhangura yakafanana.Iyo attenuation yetambo muyedzo chaiyo inogona kuratidza izvi.
Chechitatu, kubva pamamiriro ehupfumi, copper-clad aluminium conductors inotengeswa nehuremu, uye mhangura yakachena yemhangura inotengeswa nekurema, uye mutengo wemhangura-clad aluminium conductors inodhura kupfuura yakachena conductor yehuremu hwakafanana.Zvisinei, uremu hwakafanana hwemhangura-clad aluminium yakareba zvikuru kupfuura urefu hwemhangura yakachena yemhangura, uye tambo inotarwa nehurefu.Huremu hwakafanana hwemhangura-yakapfeka aruminiyamu waya inokwana 2.5 kureba kwewaya yemhangura, uye mutengo unongova mazana mashoma emayuan mamwe patani.Kutorwa pamwechete, copper-clad aluminium ine zvakawanda zvakanakira.Nekuti iyo copper-clad aluminium tambo ine zvishoma, mutengo wekufambisa uye mutengo wekuisa wetambo uchadzikiswa, izvo zvinounza kumwe kuve nyore pakuvaka.
Mukuwedzera, copper-clad aluminium cables zviri nyore kuchengetedza uye zvine mari shoma yekugadzirisa pane tambo dzemhangura dzakachena.Kushandiswa kwemhangura-akapfeka aruminiyamu kunogona kuderedza kukundikana kwetiweki uye kudzivirira vashandi vetiweki kubva "kucheka musimboti muchando uye kucheka ganda muzhizha" panguva yekuchengetedza (aluminium strip longitudinal package kana aluminium chubhu zvigadzirwa).Nekuda kwemusiyano wakakura mukupisa kwekuwedzera coefficient pakati pemhangura yemukati conductor uye aluminium yekunze conductor yetambo, mukupisa kwezhizha, aluminium yekunze conductor inokura zvakanyanya, uye conductor yemukati yemhangura inodzikira zvishoma uye haigone kunyatsobata iyo elastic contact. ndiro muF-head seat.Munguva yechando inotonhora, iyo aluminium yekunze conductor inoderera zvakanyanya, zvichiita kuti nhovo yekudzivirira iwire pasi.Kana coaxial yemukati yemhangura yakapfeka coaxial tambo, iyo yekupisa yekuwedzera coefficient pakati payo nealuminium yekunze conductor idiki, kukanganisa kwetambo core-kudhonza kunodzikiswa zvakanyanya kana tembiricha yachinja, uye hunhu hwekutapurirana hwetiweki hunovandudzwa.
Indasitiri yewaya netambo inoshandisa mhangura yakavharwa nealuminium waya zvakare inzira yakanaka yekudzikisa kudzvanywa kwazvino kwebhizinesi, iyo bimetallic waya yakagadzirwa nedhiza remhangura kunze kwewaya yealuminium, nekuda kwechikamu chidiki, kuita kwakanaka kwekufambisa uye zvimwe zvakanakira. , kunyanya yakakodzera kuita iyo yemukati conductor yeRF coaxial tambo, ichienzaniswa newakachena mhangura waya, density yayo inenge makumi mana muzana yemhangura yakachena.Iwo ekutapurirana maitiro ari nani pane yakachena mhangura waya, inova ndiyo yakanyanya kunaka RF coaxial tambo yebazi mutsara conductor.
Kugadzirwa kwemhangura-yakapfeka aluminium cable zvigadzirwa mune ramangwana kuchiri kuda iyo yese waya uye tambo indasitiri, pamwe nemabhizinesi ekugadzira kusimudzira mashandisirwo kuburikidza nekuedza kuvandudza mashandiro uye kuparidzirwa ruzivo rwechigadzirwa, kuitira kuti vabatsire mukusimbaradza.
