Cable yog siv los xa hluav taws xob (sib nqus) lub zog, hloov cov ntaub ntawv, paub txog hluav taws xob hluav taws xob hloov hluav taws xob, tsim cov kab tswj tsis siv neeg thiab tsim khoom siv hluav taws xob ntau, thiab yog ib qho khoom tseem ceeb uas yuav tsum paub txog kev hloov hluav taws xob hluav taws xob. Lub ntsiab qauv ntawm lub cable yog "conductor ntxiv rwb thaiv tsev ntxiv sheath", tus neeg xyuas pib feem ntau yog ua los ntawm tooj liab, aluminium los yog nws alloy, thiab cov rwb thaiv tsev thiab sheath feem ntau yog ua los ntawm roj hmab, polyethylene, PVC thiab lwm yam ntaub ntawv.
Kev lag luam cable yog kev lag luam yooj yim. Nws cov khoom tau siv dav hauv ntau yam kev tsim khoom thiab lub neej, xws li lub zog, kev thauj mus los, kev sib txuas lus, tsheb, petrochemical, thiab lwm yam, muab kev txhawb nqa tseem ceeb rau ntau yam kev lag luam, kev tsim kho kev lag luam thiab kev tsim kho loj. Nws yog "txoj hlab ntsha" thiab "Vajtswv" ntawm lub teb chaws kev lag luam, thiab qhov yooj yim lav rau kev ua haujlwm ntawm kev lag luam niaj hnub thiab tib neeg. Kev lag luam cable yog qhov kev lag luam loj thib ob hauv Suav teb tom qab kev lag luam tsheb, thiab ua lub luag haujlwm tseem ceeb hauv kev lag luam hauv lub tebchaws.
Los ntawm txoj kev xav ntawm cable technology txoj kev loj hlob nyob rau hauv lub ntiaj teb no, nyob rau hauv tam sim no thiab rau ib tug ntev lub sij hawm los, cov qauv rau kev soj ntsuam cov kev kawm theem ntawm cable cov khoom yog cov loj muaj peev xwm, ultra-siab (ultra-high) voltage, kub tsis kam, luv Circuit Court kuj, tsis muaj teeb meem roj tsim, txij nkawm dawb, kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob. Tebchaws Asmeskas, Nyiv thiab EU lub tebchaws tau txwv tsis pub tsim khoom, ntshuam lossis siv cov khoom siv qis kawg uas tsis ua raws li kev nyab xeeb, tsis muaj tshuaj lom, ib puag ncig rov qab los.
Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm Tuam Tshoj txoj kev lag luam, qhov ntsuas ntawm lub zog, kev sib txuas lus, lub zog, kev thauj mus los thiab lwm yam kev lag luam tau nthuav dav, thiab qhov kev thov rau cables tau loj hlob sai. Tuam Tshoj txoj kev lag luam cable kuj tau loj hlob thiab nkag mus rau lub sijhawm txhim kho kev vam meej. Raws li Cov Lus Qhia rau Kev Txhim Kho ntawm Tuam Tshoj Cable Kev Lag Luam thaum lub sijhawm "13th Tsib Xyoo Plan" (2016-2020) tau tshaj tawm thaum lub Cuaj Hlis 2016, thaum lub sijhawm "12th Tsib Xyoo Plan", kev lag luam ntawm Tuam Tshoj txoj kev lag luam cable tau tuav ib qho txoj kev loj hlob ruaj khov nyob rau hauv dav dav, thiab lub export scale tau nce. Cov zis ntawm cov hlau conductors thiab kev noj cov khoom siv kho qhov muag ntawm cov khoom lag luam tseem ceeb txuas ntxiv mus rau qib thib ib hauv ntiaj teb. Lub hauv paus kev txhim kho tag nrho ntawm kev lag luam tau ntxiv dag zog, thiab lub zog muaj zog tau raug txhim kho ntxiv.
