A. Plaub yam tseem ceeb ntawm cov cable
1. Conductive hlau core
Ua los ntawm cov khoom siv hluav taws xob siab (tooj liab lossis txhuas). Raws li qhov yuav tsum tau ua ntawm qhov softness ntawm lub cable nyob rau hauv cov kev mob ntawm nteg thiab siv, txhua tus tub ntxhais yuav raug tsim los ntawm twisting ib tug tib hlau los yog ntau yam nyob ntawm tej.
2. Txheej rwb thaiv tsev
Cov khoom siv insulating siv rau lub cable yuav tsum muaj kev rwb thaiv tsev siab. Feem ntau siv insulating cov ntaub ntawv nyob rau hauv cables yog roj-impregnated ntawv, polyvinyl chloride, polyethylene, cross-linked polyethylene, roj hmab, thiab lwm yam.
3. Sealing sheath
Tiv thaiv cov tub ntxhais insulated los ntawm kev puas tsuaj, dej noo, dej noo, tshuaj lom neeg, lub teeb, thiab lwm yam. Rau cov rwb thaiv tsev noo noo, txhuas lossis txhuas extruded hermetic seals feem ntau yog siv.
4. Kev tiv thaiv npog
Los tiv thaiv lub sealing sheath los ntawm mechanical puas. Feem ntau, galvanized steel sawb, steel hlau los yog tooj liab sawb, tooj liab hlau, thiab lwm yam yog siv los ua armor los qhwv ib ncig ntawm lub sheath (hu ua armored cable). Cov txheej armor tuaj yeem ua si ib txhij ua lub luag haujlwm ntawm hluav taws xob tiv thaiv thiab tiv thaiv kev cuam tshuam sab nraud electromagnetic yoj. Txhawm rau tiv thaiv txoj hlua hlau thiab hlau hlau los ntawm kev corroded los ntawm ib puag ncig nruab nrab, nws yog feem ntau coated nrog asphalt los yog qhwv nrog ib tug impregnated jute txheej los yog extruded polyethylene los yog polyvinyl chloride lub tes tsho.
B. Cov qauv sab hauv ntawm lub cable
1. Daim duab duab ntawm ib-core thiab ob-core cables nrog tooj liab conductors
