Ntau cov khoom siv hlau tuaj yeem siv los ua cov khoom siv hluav taws xob, sau lub luag haujlwm ntawm kev xa hluav taws xob thiab cov ntaub ntawv qhia hauv cov xov hlau, tab sis feem ntau siv yog tooj liab. Nws yog qhov nyiam rau ntau daim ntawv thov vim tias nws yog malleable heev, muaj hluav taws xob conductivity, siab saj zawg zog, siab tensile lub zog thiab yog tus pheej yig, ua rau nws nyiam xaiv rau ntau daim ntaub ntawv.
Aluminium kuj yog cov khoom siv hluav taws xob uas nws qhov txiaj ntsig tseem ceeb yog tias nws yog qhov ntom ntom dua li tooj liab. Txawm li cas los xij, nws cov khoom siv hluav taws xob tsis zoo txhais tau hais tias yuav tsum muaj qhov sib txuas loj dua los nqa tib qhov tam sim no. Tsis tas li ntawd, cov xov hlau txhuas tsis khoov zoo txaus, uas ua rau muaj kev pheej hmoo ntawm kev tawg, yog li lawv tsis haum rau siv hauv kev siv mobile. Vim li no, txhuas feem ntau yog siv rau hauv lub zog xa hluav taws xob cables thiab nruab nrab-voltage cables vim qhov hnyav yuav tsum tau siv rau cov ntawv thov.
Ntawm cov hlau, cov khoom siv hluav taws xob zoo tshaj plaws yog nyiaj, tab sis nws yog ntau zaus kim dua tooj liab. Yog li ntawd, nyiaj feem ntau tsuas yog siv rau hauv cov ntawv tshwj xeeb uas xav tau kev ua tau zoo thiab kev ua haujlwm zoo, xws li cov khoom siv suab nrov. Lwm qhov kev xaiv tus neeg xyuas pib rau lub cables yog nyiaj-plated tooj liab hlau, uas muaj cov conductivity siab thiab corrosion kuj. Kub yog tsis tsim nyog raws li ib tug neeg xyuas pib vim nws cov nqi siab thiab tsis zoo conductivity piv rau nyiaj thiab tooj liab.
Muaj ib qho khoom siv uas tsis tshua muaj hluav taws xob tsawg dua li tooj liab lossis txhuas, thiab thaum xub thawj siab ib muag kuj zoo li tsis tsim nyog raws li cov khoom siv hluav taws xob. Txawm li cas los xij, nws yog tus cwj pwm los ntawm nws qhov siab hardness thiab tensile zog - steel. Yog li ntawd, hlau yog dav siv hauv kev siv tub rog thiab aerospace, feem ntau ua ke nrog lwm cov ntaub ntawv xws li txhuas alloys.
Ntxiv nrog rau cov khoom siv hlau no, muaj cov fibers optical lossis optical waveguides. Cov no yog qhov tsim nyog rau kev sib kis ceev ntawm cov teeb liab optical. Lawv muaj xws li ib tug quartz iav los yog yas fiber core. Cov tom kawg yog hloov tau yooj yim dua thiab yog li ntawd yooj yim rau khoov. Cov tub ntxhais fiber ntau zaum hauv kev tiv thaiv cladding, hu ua cladding. Lub teeb yog reflected ntawm lub optical core thiab cladding thiab yog li kis ntawm kev kub ceev los ntawm lub waveguide. Optical waveguides yog siv nyob 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 tam sim no.
Kev xaiv ntawm cov khoom siv zoo tshaj plaws yog nyob ntawm 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, nws yog ib qho tseem ceeb kom nkag siab txog cov khoom ntawm cov khoom. Ntawm chav kawm, lwm yam ntxwv ntawm lub cable, xws li txoj kev stranding, cross-sectional cheeb tsam, rwb thaiv tsev thiab sheath cov ntaub ntawv kuj ua lub luag hauj lwm tseem ceeb. Vim li no, koj tseem tuaj yeem nrhiav cov lus qhia ntawm cov kws tshaj lij cable hauv kev xaiv cov cables thiab cov xov hlau los xyuas kom meej tias txhua qhov kev xav tau rau kev siv txhua hnub tau ntsib.
