1. Cov txheej txheem tsim khoom loj hlob, yooj yim rau kev tsim thiab ua tiav
2. Piv nrog rau lwm hom cable rwb thaiv tsev, PVC insulated hlau thiab cable tsis yog tsuas yog pheej yig xwb, tab sis kuj tseem muaj qhov sib txawv ntawm xim ntawm qhov chaw, qhov tsaus ntuj, luam ntawv, kev ua haujlwm zoo, qhov nyuaj, kev nplaum ntawm tus neeg coj, cov khoom siv lub cev thiab cov khoom siv hluav taws xob ntawm cov hlau nws tus kheej, thiab lwm yam. Txhua yam tuaj yeem tswj tau zoo; nws muaj cov khoom tiv thaiv hluav taws zoo heev, yog li PVC insulated hlau thiab cables tuaj yeem yooj yim ncav cuag cov qib tiv thaiv hluav taws uas tau teev tseg hauv ntau tus qauv.
3. Feem ntau cov hlau yog nyob rau hauv qhov hnyav teev tseg. Lub sheath siv rau hauv cov ntaub hlau yog polyvinyl chloride rwb thaiv tsev. Cov hlau rwb thaiv tsev yuav tsum muaj qhov zoo li du nrog cov ntawv luam tawm meej. Pom los ntawm qhov kawg ntawm cov hlau, cov rwb thaiv tsev yuav tsum yog txawm thiab tsis eccentric.
