Tag nrho cov hom qhuav fiber ntau optical fiber yog gel-dawb, tag nrho cov cable txais yuav dej thaiv cov xov paj, dej thaiv kab xev thiab dej thaiv iav xov paj los tiv thaiv cable tiv thaiv dej.
Piv rau gel, dej thaiv daim kab xev (https://www.china-longvision.com/water-swellable-tape/water-swellable-non-conductive-tape.html) thiab dej thaiv cov xov paj (https://www.china-longvision.com/water-swellable-yarn/water-blocking-yarn-and-thread-for-fiber.html)yog dej swellable cov ntaub ntawv, lawv muaj qhov zoo ntawm lub teeb yuag, huv si thiab yooj yim rau cable installation txheej txheem, thiab zoo compatibility rau lwm yam ntaub ntawv xws li ntau yam cable compound. Tsis tas yuav ntxuav gel los ntawm fibers ua ntej splicing, gel-dawb cables pab ceev thiab npaum splicing npaj thiab tsav tus nqi txuag los ntawm kev tshem tawm cov khoom siv tu.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm dej thaiv kev ua haujlwm yog, thaum cov dej los yog cov dej noo nkag mus rau hauv FO cable, cov ntaub ntawv swells ib zaug sib cuag nrog dej, sau rau hauv interspaces thiab nres qhov kev nkag mus ntawm dej ntxiv. Ib sab, cov xov paj nyias siv hauv cov raj xoob feem ntau muaj cov yam ntxwv ntawm kev nqus dej, uas ob npaug kev tiv thaiv los ntawm dej nkag.
Dab tsi ntxiv, hauv qee qhov kho qhov muag fiber ntau cable, lub cable yog ntxiv dag zog nrog dej thaiv fiberglass yarn (https://www.china-longvision.com/strength-yarn-for-cable/water-blocking-fiberglass-yarn-for-cable.html), fiberglass yarn yog muab lub peev xwm ntawm dej o. Ntawm ib sab tes cov xov paj fiberglass muaj zog tuaj yeem ua ib feem ntawm cov tswv cuab lub zog; Ntawm qhov tod tes, cov dej thaiv iav tuaj yeem tiv taus dej thiab tiv thaiv nas, vim tias cov iav tawg yog prickling rau nas.
Daim duab 1
Nyob rau saum toj kab qauv Daim duab 1 ua piv txwv, cov dej swellable iav yarn, piv txwv li dej thaiv iav xov paj ua raws li cov tswv cuab lub zog tensile. Lub cable muaj lub teeb yuag kev tsim kho thiab txoj kab uas hla me me, nws yog qhov zoo tagnrho rau kev teeb tsa hauv ntau qhov sib txuas.
Daim duab 2
Nyob rau saum toj no cable qauv Daim duab 2, vim hais tias ntawm daim ntawv thov ntawm dej swellable iav yarn, lub cable muaj zoo heev nas tiv thaiv thiab yog haum rau ncaj nteg rau hauv av.
