Tus qauv tsim ntawm kev tswj cov cables nyob rau hauv cov ntsiab lus ntawm "kev ruaj ntseg teeb liab kis tau tus mob, muaj zog los tiv thaiv- muaj peev xwm cuam tshuam, thiab hloov mus rau ib puag ncig nyuaj." Lawv cov yam ntxwv tseem ceeb tau tshwm sim hauv plaub yam tseem ceeb hauv qab no:
Tus neeg xyuas pib: Feem ntau siv tooj liab conductors (txawm hais tias aluminium conductors qee zaus siv nyob rau hauv cov xwm txheej uas yuav tsum tau qis dua). Cov no feem ntau yog tsim los ntawm stranding ntau cov hlau zoo tooj liab ua ke. Piv nrog rau cov khoom, nruj conductors, cov stranded qauv no muaj superior saj zawg zog, yooj yim installation nyob rau hauv ib puag ncig yam ntxwv los ntawm high-zoo khoom ceev thiab confined thaiv qhov chaw. Tsis tas li ntawd, nws txo qis tus neeg xyuas pib kev puas tsuaj los ntawm kev khoov, yog li ua kom muaj kev txuas ntxiv ntawm cov teeb liab kis.
Rwb thaiv tsev txheej: Cov ntaub ntawv muaj xws li Polyvinyl Chloride (PVC), Hla -Txuas Polyethylene (XLPE), lossis Polyethylene (PE). Lub rwb thaiv tsev txheej yuav tsum muaj cov rwb thaiv tsev siab thiab tsis tshua muaj dielectric poob yam ntxwv. Ntawm ib sab tes, qhov no tiv thaiv cov xau tam sim no ntawm cov neeg siv hluav taws xob lossis nruab nrab ntawm cov khoom siv hluav taws xob thiab ib puag ncig sab nraud; Ntawm qhov tod tes, nws tiv thaiv cov txheej txheem rwb thaiv tsev nws tus kheej los ntawm attenuating lub teeb liab, yog li xyuas kom meej qhov kev sib kis ntawm kev tswj tsis muaj zog. Tsis tas li ntawd, cov txheej txheem rwb thaiv tsev yuav tsum muaj qee qhov kev ruaj ntseg thermal (feem ntau muaj peev xwm tiv taus qhov kub ntawm -20℃txog 70 degree) kom ua tau raws li qhov yuav tsum tau ua nyob rau hauv ntau yam kev ua haujlwm.
Kev Tiv Thaiv Txheej Txheem (Tam sim no nyob rau hauv cov qauv xaiv): Tsim los rau ib puag ncig uas cuam tshuam rau electromagnetic cuam tshuam (xws li thaj chaw nyob ze rau siab - cov khoom siv hluav taws xob, zaus hloov hluav taws xob, lossis lub tshuab hluav taws xob), tswj cov cables hauv cov ntawv thov no suav nrog txheej tiv thaiv. Cov ntaub ntawv feem ntau muaj xws li braided tooj liab hlau mesh, qhwv tooj liab daim kab xev, los yog txhuas-plastic composite daim kab xev. Nws lub luag haujlwm tseem ceeb yog txhawm rau thaiv cov teeb liab hluav taws xob sab nraud los ntawm kev cuam tshuam nrog cov teeb liab tswj sab hauv hauv lub cable, thaum tib lub sijhawm tiv thaiv cov kab hluav taws xob ntawm tus kheej los ntawm kev tawm sab nraud- yog li tsis txhob cuam tshuam nrog lwm cov khoom siv peripheral rhiab heev - thiab xyuas kom meej qhov purity ntawm cov teeb liab tswj.
Sheath Layer: Ua hauj lwm raws li lub cable "lub plhaub tiv thaiv sab nraud," txheej txheej no feem ntau yog tsim los ntawm PVC, Neoprene roj hmab, lossis Polyolefin. Nws yuav tsum muaj cov yam ntxwv xws li tiv thaiv kev puas tsuaj, kev laus, roj, thiab tshuaj lom neeg corrosion.
