Cov ntaub ntawv siv rau kev sib dhos cable raug xaiv feem ntau raws li qhov chaw ua haujlwm, kev sib kis tau zoo, thiab cov kev xav tau kev nyab xeeb. Cov khoom tseem ceeb muaj xws li conductors, rwb thaiv tsev txheej, shielding txheej, thiab cov tsho sab nrauv. Cov neeg siv hluav taws xob feem ntau yog ua los ntawm cov hlau xws li tooj liab lossis txhuas los xyuas kom ruaj khov ntawm cov hluav taws xob xaim hluav taws xob lossis lub zog. Cov ntaub ntawv rwb thaiv tsev feem ntau muaj xws li polyvinyl chloride (PVC), polyethylene (PE), thiab polytetrafluoroethylene (PTFE), uas txhim kho cov kab hluav taws xob tiv thaiv, tiv thaiv tshav kub, thiab insulating zog.
Tiv thaiv thiab tiv thaiv cov ntaub ntawv tseem ua lub luag haujlwm tseem ceeb hauv kev tsim khoom. Txhawm rau txo qis kev cuam tshuam sab nraud ntawm electromagnetic, qee cov cables suav nrog cov qauv thaiv kev tiv thaiv-xws li tooj liab ntawv, aluminium ntawv ci, lossis braided tooj liab mesh- txhawm rau txhim kho cov teeb liab kev ruaj ntseg. Cov ntaub ntawv tsho sab nrauv yuav tsum muaj kev tiv thaiv zoo heev, tiv thaiv corrosion, thiab kav ntev tiv thaiv kev laus; Cov kev xaiv feem ntau suav nrog PVC, roj hmab, thiab polyurethane, xaiv raws li cov ntawv thov tshwj xeeb xws li cov cuab yeej siv, tsheb, cov phiaj hluav taws xob, lossis kev sib txuas lus.
Raws li kev siv thev naus laus zis, kev ua haujlwm ntawm cov khoom siv rau kev sib txuas cable txuas ntxiv nce. Cov khoom siv hluav taws xob niaj hnub no yuav tsum tsis yog tsuas yog muaj cov khoom siv hluav taws xob zoo thiab lub zog siv hluav taws xob xwb tab sis kuj ua tau raws li cov qauv tsim qauv, kev ua phooj ywg ib puag ncig, thiab kev ntseeg siab ntev - lub sijhawm ua haujlwm. Cov ntawv thov tshwj xeeb tuaj yeem siv siab -kub resistant, nplaim taws- retardant, los yog tsawg- pa taws xoom- halogen (LSZH) cov ntaub ntawv los txhim kho kev nyab xeeb thiab ib puag ncig adaptability. Yog li ntawd, kev xaiv thiab kev sib xyaw ua ke ntawm cov khoom siv yog qhov tseem ceeb hauv kev ua kom zoo thiab kev pabcuam lub neej ntawm cov khoom siv cable.
