Vim qhov kev ntshai ntawm cov dej noo thiab dej hauv cov fibers kho qhov muag, nws yuav tsum muaj cov khoom siv kho qhov muag yuav tsum muaj cov dej tsis zoo. Waterproofing yog muab faib ua kab rov tav thiab ntsug waterproofing. Kab rov tav waterproofing yog tsuas yog siv los tiv thaiv dej los ntawm kev nkag mus rau hauv lub optical cable ib zaug lub txheej sheath puas lawm, thaum ntsug waterproofing yog siv los tiv thaiv dej los ntawm nkag mus rau hauv lub cable rau ib tug ntev kev ncua deb tom qab txiav, ua rau nws nyuaj rau kho.
Kab rov tav waterproofing
Kab rov tav waterproofing feem ntau suav nrog cov kev ntsuas hauv qab no: sau lub raj xoob nrog roj, sau cov tub ntxhais cable nrog roj, qhov ntev qhwv ntawm aluminium thiab steel strips. Rau longitudinal waterproofing, ntxiv rau sau lub tes tsho xoob thiab cov tub ntxhais cable nrog roj, cov dej thaiv cov nplhaib yog siv los kaw cov cables qhwv hauv steel strips longitudinally. Cov kev ntsuas no ua tau zoo tiv thaiv dej nkag.
Kev ua tau zoo ntawm cov dej tsis zoo thiab cov dej noo-pov thawj ntawm optical cables yog muab los ntawm cov txheej txheem hauv qab no.
Waterproof tshuaj pleev
Siv los sau qhov sib txawv ntawm cov txheej txheem tiv thaiv ntawm cov kab hluav taws xob kho qhov muag thiab cov khoom siv kho qhov muag kom tiv thaiv cov dej noo infiltration.
Kev tiv thaiv txheej
Cov txheej tiv thaiv sab nraud ntawm ib qho khoom siv kho qhov muag, feem ntau yog ua los ntawm cov ntaub ntawv xws li polyethylene lossis polyurethane, nrog kev ua haujlwm zoo ntawm cov dej tsis zoo.
Aluminium yas bonding sheath: Ib qho ntawm cov ntaub ntawv sheath, uas txhim kho cov dej tsis zoo ntawm cov ntaub qhwv los ntawm kev siv tshuab aluminium-yas bonding.
Hlau yas sib txuas sheath
Ib qho ntawm cov ntaub ntawv sheath, uas txhim kho cov dej tsis zoo ntawm cov sheath los ntawm steel yas bonding technology.
Cov qauv tsim qauv ua haujlwm ua ke los xyuas kom meej tias cov kab hluav taws xob kho qhov muag tuaj yeem ua haujlwm ruaj khov hauv qhov chaw ntub dej lossis dej rau hauv qhov chaw.
