Sab nraum zoov cable luv luv cable rau kev siv sab nraum zoov, yog zwm rau cov hluav taws xob fiber ntau cable, vim tias tsim nyog rau siv sab nraum zoov thiaj li hu ua fiber ntau sab nraum zoov cable, nws yog lub sijhawm ntev ntev, tuaj yeem tiv cov cua thiab hnub thiab txias, thiab ntim tuab, muaj qee yam xws li tshuab, ib puag ncig cov cuab yeej siab, kev txhim kho corrosion, tensile lub zog thiab cov zoo li.
Ntev seepage dej thaiv cov kab xev longitudinally los tiv thaiv cov cable
Ob txoj hlua hlau txuas hluav taws xob txhawm rau ua kom lub zog tensile
Tensile lub zog sab nraum zoov kho qhov muag cable yog qhov loj, qhov tiv thaiv txheej txheej yog qhov tuab thiab hnyav, thiab feem ntau (piv txwv li hlau tawv qhwv) yog armored. Sab nraum zoov fiber optic cable yog mas thov rau kev sib cuam tshuam ntawm nruab nrab ntawm cov tuam tsev, nrog rau kev sib txuas deb cov chaw.
Nyob rau hauv dav dav, sab nraum zoov kho qhov muag cable tsuas yog fillers, txhawb nqa tus tswv cuab sib txawv, lub tsho thiab lwm cov khoom xaiv. Xws li: Thaum sab nraum zoov cable faus, yuav tsum tau siv cov xov tooj armored. Cable dub yas sab sab sheath thaum sim saum nruab ntug, tuaj yeem xaiv nrog ob lossis ntau qhov stiffeners.
Cov kab hluav taws xob sab nraud vim tias nws siv qhov chaw ib puag ncig sab nraud, nws yog qhov tsim nyog yuav tsum muaj dej ua kom tsis muaj dej, cov kab xev sab nraud feem ntau siv yog PE khoom ua, thiab nws cov qauv sab hauv feem ntau muab faib ua tubular cov qauv thiab cov txheej txheej ntswj.
Los ntawm cov ntsiab lus pom kev zoo sab hauv, cov hnab riam sab hauv sab hauv feem ntau yog xim daj lossis txiv kab ntxwv PVC cov khoom, sab nraum zoov dub khoom PE hnab riam, los ntawm hom sib txawv sab nraum zoov feem ntau hais GY ntawm.
Sab nraum zoov hluav taws xob cable: ntim tuab, muaj lub siab tsis kam, qee yam ntawm cov khoom kho tshuab, ib puag ncig cov khoom ntawm kev txhim kho corrosion, nro thiab cov zoo li.
Sab hauv tsev cable: feem ntau yog siv sab hauv tsev, cov yam ntxwv tseem ceeb muaj cov yam ntxwv hloov tau, tuaj yeem siv rau hauv kaum thiab lwm qhov chaw kaw, thiab qhov thib ob yuav tsum muaj hluav taws kub retardant, tensile, mos extrinsic yam ntxwv.
Sab nraud cable yog ua tiav hluav taws xob teeb liab kis tau txais kev sib txuas lus. Los ntawm qee qhov muaj pes tsawg tus ntawm cov xov hluav taws xob nyob rau hauv raws li qee yam kev tsim ua ke ntawm cov tub ntxhais txoj hlua cable, sab nraud sheath, thiab qee qhov npog sab hauv hnab riam.
Sab nraud cov kab hluav taws xob feem ntau yog ua los ntawm cov khoom siv hluav taws xob (zoo li cov plaub hau sib zog ntawm lub iav) thiab cov plasma nkawm tes tsho thiab cov hnab yas plooj teeb, lub cable tsis pub dawb kub, nyiaj, tooj thiab txhuas thiab lwm yam hlau.
