Cov txheej txheem khaws cia cov khoom siv cable yog tsim los ua kom cov khoom ruaj khov thiab tiv thaiv cov khoom siv hluav taws xob, kev puas tsuaj, lossis kev puas tsuaj ntawm cov khoom hluav taws xob los ntawm kev cia khoom tsis raug. Qhov chaw cia khoom tsim nyog yuav tsum raug xaiv raws li cov khoom siv thiab cov kev xav tau ntawm cov khoom siv cable. Feem ntau, qhov chaw cia yuav tsum tau qhuav thiab huv si, tiv thaiv los ntawm lub hnub ncaj qha mus ntev, thiab nyob deb ntawm qhov kub thiab txias, av noo, corrosive gases, thiab cov khoom uas tuaj yeem ua rau puas tsuaj.
Kev npaj kom raug thiab kev tiv thaiv yuav tsum tau ua thaum lub sijhawm khaws cia. Cables yuav tsum tsis txhob raug compression ntau dhau, ncab, lossis khoov; lawv yuav tsum tau coiled raws li tau teev tseg bending radii los tiv thaiv kev puas tsuaj rau sab hauv conductors thiab rwb thaiv tsev txheej. Rau cov cable sib dhos uas muaj cov khoom sib txuas, kev tiv thaiv kev sib txuas yog qhov tseem ceeb los tiv thaiv kev puas tsuaj rau cov terminals los ntawm kev cuam tshuam, kev sib kis, lossis oxidation; lub kaus mom tiv thaiv lossis cov khoom ntim yuav tsum tau siv thaum tsim nyog.
Txhawm rau kom ntseeg tau tias qhov zoo ntawm cov khoom siv cable sib dhos, yuav tsum tsim kom muaj ib qho kev tshuaj xyuas thiab kev tswj xyuas tsis tu ncua. Thaum lub sij hawm cia, cov khoom zoo li, ntim, thiab lub xeev ntawm connectors yuav tsum tau soj ntsuam; txhua yam teeb meem xws li kev puas tsuaj sheathing, ya raws, los yog lwm yam anomalies yuav tsum tau hais tam sim ntawd. Rau cov rooj sib txoos khaws cia rau lub sijhawm ntev, kev kuaj xyuas kev ua haujlwm tsim nyog yuav tsum tau ua ua ntej xa mus kom paub tseeb tias lawv ua tau raws li qhov yuav tsum tau ua ua ntej kev teeb tsa. Standardized cia tswj tau zoo txuas ntxiv lub neej kev pab cuam ntawm cable sib dhos thiab txhim khu lawv kev ntseeg tau thaum siv.
