Muaj ntau yam khoom siv hlau siv tau ua cov hlau hluav taws xob, ua lub luag haujlwm xa hluav taws xob thiab xa cov ntaub ntawv hauv cov xov hlau cable, tab sis feem ntau siv yog tooj liab. Nws nyiam siv rau ntau daim ntawv thov vim nws yooj yim hloov pauv, muaj kev coj hluav taws xob siab, yooj ywm, muaj zog tensile siab thiab pheej yig, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau daim ntawv thov.
Aluminium kuj yog ib yam khoom siv uas nws qhov zoo tshaj plaws yog tias nws tsis hnyav npaum li tooj liab. Txawm li cas los xij, nws txoj kev ua hluav taws xob tsis zoo txhais tau tias yuav tsum muaj qhov seem loj dua kom nqa tau tib yam tam sim no. Tsis tas li ntawd, cov xov hlau aluminium tsis khoov zoo txaus, uas ua rau muaj kev tawg ntau dua, yog li lawv tsis haum rau kev siv hauv cov ntawv thov mobile. Vim li no, aluminium feem ntau yog siv rau hauv cov xov hluav taws xob thiab cov xov hlau nruab nrab vim qhov hnyav uas yuav tsum tau ua rau cov ntawv thov no.
Ntawm cov hlau, cov khoom siv hluav taws xob zoo tshaj plaws yog nyiaj, tab sis nws kim dua tooj liab ntau zaus. Yog li ntawd, nyiaj feem ntau tsuas yog siv rau hauv cov ntawv thov tshwj xeeb uas xav tau kev ua tau zoo thiab ua haujlwm tau zoo, xws li cov khoom siv suab siab. Lwm cov hlau txuas ntxiv xaiv tau rau cov xov hlau suab yog hlau tooj liab uas muaj nyiaj, uas muaj kev hluav taws xob zoo thiab tiv taus xeb. Kub tsis haum ua hlau txuas ntxiv vim nws tus nqi siab thiab kev hluav taws xob tsis zoo piv rau nyiaj thiab tooj liab.
Muaj ib yam khoom uas tsis tshua muaj hluav taws xob ntau dua li tooj liab lossis txhuas, thiab thaum xub thawj siab zoo li tsis tsim nyog ua cov khoom siv hluav taws xob. Txawm li cas los xij, nws yog tus cwj pwm los ntawm nws qhov nyuaj thiab lub zog tensile - hlau. Yog li ntawd, hlau yog siv dav hauv kev siv tub rog thiab aerospace, feem ntau ua ke nrog lwm yam khoom xws li txhuas alloys.
Ntxiv rau cov hlau conductors no, muaj optical fibers lossis optical waveguides. Cov no zoo tagnrho rau kev xa cov teeb liab optical ceev ceev. Lawv muaj cov iav quartz lossis yas fiber core. Qhov kawg yog qhov yooj ywm dua thiab yog li ntawd yooj yim dua rau khoov. Lub fiber core nyob hauv ib lub cladding tiv thaiv, hu ua cladding. Lub teeb raug cuam tshuam ntawm lub optical core thiab cladding thiab yog li xa mus rau qhov ceev ceev los ntawm waveguide. Optical waveguides siv rau hauv ntau yam kev siv xws li kev sib txuas lus, tshuaj thiab aerospace. Txawm li cas los xij, lawv tsis tuaj yeem xa cov hluav taws xob.
Qhov kev xaiv cov khoom siv conductor zoo tshaj plaws nyob ntawm seb daim ntawv thov tshwj xeeb thiab cov xwm txheej uas twb muaj lawm. Yuav kom ua tib zoo xav txog qhov zoo thiab qhov tsis zoo ntawm txhua yam khoom siv, nws yog ib qho tseem ceeb kom nkag siab txog cov yam ntxwv ntawm cov khoom siv. Tau kawg, lwm yam ntxwv ntawm cov cable, xws li txoj kev stranding, thaj chaw hla, rwb thaiv tsev thiab cov ntaub ntawv sheath kuj ua lub luag haujlwm tseem ceeb. Vim li no, koj tuaj yeem nrhiav cov lus qhia ntawm cov kws tshaj lij cable hauv kev xaiv cov cables thiab cov xov hlau kom ntseeg tau tias txhua yam kev xav tau rau kev siv txhua hnub tau ua tiav.
