Cov qauv ntawm kev tswj cable feem ntau yog tsim los ntawm cov khoom siv hluav taws xob, rwb thaiv tsev, tiv thaiv, sheath thiab armor. Tus neeg xyuas pib yog qhov tseem ceeb ntawm cov cable, feem ntau yog siv tooj liab lossis txhuas ua cov khoom siv, nyob ntawm kev siv sib txawv, tuaj yeem muaj ib daim ntawv los yog ntau yam. Rwb thaiv tsev yog cais cov hluav taws xob sib txuas ntawm cov neeg siv hluav taws xob thiab nruab nrab ntawm cov neeg siv hluav taws xob thiab lub ntiaj teb sab nraud, feem ntau yog siv cov yas xws li polyvinyl chloride lossis cross-linked polyethylene ua cov khoom siv. Shielding yog txhawm rau tiv thaiv cov kab hluav taws xob los ntawm cov hluav taws xob sab nraud los yog cuam tshuam rau lub ntiaj teb sab nraud, feem ntau yog siv cov khoom siv hlau xws li tooj liab hlau, tooj liab strip los yog aluminium-yas composite daim kab xev ua ib txheej thaiv. Lub sheath yog tsim los tiv thaiv cov cable los ntawm kev puas tsuaj, tshuaj lom neeg corrosion thiab ib puag ncig, thiab feem ntau yog ua los ntawm cov yas xws li polyvinyl chloride lossis roj hmab. Armoring yog los txhim kho cov neeg kho tshuab lub zog thiab lub zog sab nraud ntawm lub cable, feem ntau yog siv cov ntaub ntawv hlau xws li steel daim kab xev los yog steel hlau ua armoring txheej.
