Copper cable thiab aluminium cable yog cov khoom siv tseem ceeb rau kev xaim hluav taws xob, kev faib hluav taws xob engineering, thiab cov khoom siv sib txuas. Ntau tus neeg xav tsis thoob los ntawm qhov laj thawj rau tus nqi siab dua ntawm tooj liab cable. Qhov tseeb, nws tus nqi siab tsis yog vim kev ua lag luam speculation, tab sis yog qhov muaj txiaj ntsig zoo ntawm tsib qhov ntev: cov khoom siv ntxhia, kev ua haujlwm zoo, lub cev zoo, kev ruaj ntseg ruaj ntseg, thiab kev ua thiab rov ua dua tus nqi. Ntau qhov sib txawv nyuaj sib koom ua ke txhawb tus nqi hwm ntawm tooj liab cable.
①.Resource endowment disparity:Tus nqi sib txawv ntawm cov khoom siv raw yog lub hauv paus tseem ceeb.
Tus nqi tseem ceeb ntawm cables yog concentrated nyob rau hauv cov khoom siv conductor. Qhov sib txawv ntawm cov khoom siv ntxhia ntawm tooj liab thiab txhuas yog thawj qhov laj thawj rau tus nqi sib txawv. Aluminium muaj ntau reserves nyob rau hauv lub ntiaj teb crust, thiab cov mining thiab beneficiation ntawm txhuas ore yog ib qho yooj yim, nrog ruaj khov thiab txaus txaus, thiab cov khoom raw cov nqi yog ntev - lub sij hawm tsawg. Thaum tooj liab yog ib qho tsis tshua muaj -ferrous hlau, siab-qib tooj liab ore cov peev txheej tau maj mam depleted, thiab cov ore seem muaj qis dua, nrog cov txheej txheem nyuaj thiab raug nqi mining thiab smelting.
Cov ntaub ntawv lag luam qhia tau hais tias tus nqi tonnage ntawm tooj liab yog ntev - lub sij hawm ob zaug mus rau peb npaug ntawm txhuas. Raws li cov khoom siv hluav taws xob tso nyiaj ntau dua 80% ntawm tag nrho cov nqi ntawm cov cables, cov khoom siv raw khoom loj sib txawv ncaj qha nteg lub hauv paus rau tus nqi siab dua ntawm cov tooj liab cables.
②. Conductive kev ua tau zoo superiority:Tus nqi sib tw yog qis dua nyob rau hauv tib lub sijhawm
Conductive efficiency yog qhov taw qhia tseem ceeb ntawm cables. Qhov kev ua tau zoo ntawm tooj liab thiab txhuas yog qhov pom tseeb heev. Lub resistivity ntawm tooj liab yog kwv yees li 0.0175 Ω·mm² / m, thaum lub txhuas yog kwv yees li 0.0283 Ω·mm² / m. Lub conductivity efficiency ntawm txhuas tsuas yog hais txog 61% ntawm cov tooj liab. Raws li tib yam kev qhia tshwj xeeb thiab kis tau tus mob, cov xov tooj tooj liab muaj qhov loj dua tam sim no - nqa lub peev xwm, qis kab poob, thiab tsawg dua cov cua sov thaum lub sijhawm ua haujlwm, thiab muaj kev sib kis ntau dua li cov kab hluav taws xob txhuas.
Yog tias aluminium cables xav kom ua tiav cov txiaj ntsig zoo ib yam li tooj liab cables, cable cross -section yuav tsum tau nce, uas tsis tsuas yog offsets tus nqi qis ntawm aluminium tab sis kuj nce qhov hnyav thiab qhov chaw ua hauj lwm ntawm cable, thiab nce tus nqi ntawm kev txhawb nqa engineering xws li txuas hniav thiab kav dej. Copper cables nrog tus ntoo khaub lig me me -section tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm qhov loj - fais fab kis tau tus mob, muaj zog yoog raws, thiab qis dua - lub sij hawm siv hluav taws xob, thiab muaj txiaj ntsig zoo tag nrho.
③.Lub cev ua tau zoo heev:Durability thiab cov xwm txheej siv tau dav dua
Cov khoom siv hluav taws xob ntawm cov kab hluav taws xob txiav txim siab lub neej kev pab cuam thiab cov xwm txheej siv tau. Copper muaj cov khoom zoo heev, toughness, thiab tensile lub zog, yog resistant rau dabtsi yog khoov thiab stretching, thiab nws tsis yooj yim rau breakage tom qab siv dua, nrog tsawg ua poob thiab siab yield tus nqi, thiab yuav tau yoog mus rau saj zawg zog thaiv nyob rau hauv lub tsev kho kom zoo nkauj, mobile devices, precision instruments, motors, thiab lwm yam complex wiring scenarios. Nws durability yog heev muaj zog.
Aluminium yog mos, tsis muaj zog tensile thiab toughness, thiab cov tub ntxhais tsis muaj zog yog nws tsis muaj peev xwm tiv taus dabtsi yog khoov. Kev khoov ntau zaus yuav ua rau muaj kev tawg, thiab nws tsis tuaj yeem hloov mus rau cov xov tooj ntawm tes lossis cov xov hlau tsis sib haum. Txawm tias muaj tus ntoo khaub lig loj -section tsau aluminium cables, steel cores yuav tsum tau muab ntxiv rau kev txhawb nqa, nce cov txheej txheem thiab cov khoom siv, thiab cov qauv kev ruaj ntseg tseem qis dua li ntawm cov tooj liab cables.
④.ruaj khov thiab corrosion-cov khoom tiv thaiv:Kev nyab xeeb siab dua thiab qis dua tus nqi tsis ua haujlwm
Feem ntau muaj kev nyab xeeb ntawm cov cables los ntawm oxidation thiab corrosion ntawm cov connectors. Tooj liab muaj cov tshuaj tiv thaiv zoo tshaj -oxidation thiab tiv thaiv- kev ua haujlwm corrosion, thiab nws tsis yooj yim rau deterioration nyob rau hauv huab cua thiab huab cua puag ncig. Qhov kev tiv thaiv ntawm lub connector yog ruaj khov, thiab tsis tshua muaj teeb meem xws li overheating, sparking, thiab luv circuits. Kev ua haujlwm siab yog me me, thiab kev nyab xeeb coefficient siab.
Txhuas muaj cov tshuaj lom neeg muaj txiaj ntsig thiab ua rau muaj kev ua haujlwm siab -cov yeeb yaj kiab oxide nyob rau saum npoo, uas yooj yim ua rau kev sib cuag tsis zoo, tsis muaj zog xa mus, thiab cov teeb meem loj tuaj yeem ua rau kab tsis zoo. Kev tsim kho aluminium cable yuav tsum muaj cov txheej txheem siab heev thiab cov khoom siv, txawm tias cov qauv tsim, kev laus, corrosion, thiab loosening txaus ntshai ntawm aluminium cables nyob rau lub sij hawm ntev yog ntau dua li cov tooj liab cables.
⑤. Kev ua thiab rov ua dua qhov zoo:Zoo tag nrho cov nqi ua tau zoo thoob plaws hauv lub neej voj voog
Los ntawm tag nrho lub neej voj voog txoj kev xav, tus nqi kom zoo dua ntawm tooj liab cables yog qhov tseem ceeb dua. Nyob rau hauv cov txheej txheem ntau lawm, cov khoom siv tooj liab hloov tau yooj yim thiab yooj yim rau kev ua, nrog kev poob qis thiab cov txiaj ntsig siab ntawm txhua tus txheej txheem, thiab cov nqi tsim khoom yog tswj tau; aluminium yog nkig thiab yooj yim rau kev tawg, nrog rau kev ua kom raug siab, thiab cov khoom poob thiab cov nqi ntau dua.
Hais txog kev rov ua dua tshiab, kev lag luam xav tau rau cov khoom seem tooj liab yog qhov loj, tus nqi ruaj khov, thiab cov nqi seem yog qhov tseem ceeb, thaum cov nqi rov ua dua ntawm txhuas yog tsawg. Zuag qhia tag nrho, txawm hais tias thawj tus nqi ntawm cov tooj liab cables yog siab dua, nrog rau qhov zoo ntawm durability, kev txuag hluav taws xob thiab kev txo qis, thiab cov nqi seem siab, tag nrho cov nqi ntawm cov tooj liab cables nyob deb tshaj li ntawm txhuas cables thoob plaws hauv lub neej.
