Hauv kev tsim cov xov hlau niaj hnub no, cov ntaub ntawv sau cov xov hlau, txawm hais tias tsis koom nrog kev coj hluav taws xob ncaj qha, yog cov khoom tseem ceeb uas ua kom muaj kev ruaj khov ntawm cov qauv, lub zog kho tshuab, thiab kev ntseeg siab mus sij hawm ntev ntawm cov xov hlau. Lawv lub luag haujlwm tseem ceeb yog sau cov qhov sib txawv ntawm cov xov hlau, rwb thaiv tsev, lub plhaub, thiab lwm cov txheej kom tswj tau qhov sib npaug, tiv thaiv cov qauv tsis zoo xws li qhov sib txawv ntawm lub hauv paus, qhov tsis sib npaug, thiab kev cuam tshuam, thiab xyuas kom meej tias muaj kev sib txuas zoo ntawm cov txheej thaum lub sijhawm cabling. Qhov no pab txhawb rau kev hloov pauv tau zoo dua, kev ua haujlwm kho tshuab, thiab kev ruaj khov ntawm cov xov hlau.
Ntawm ntau yam khoom siv cable filling,PP filler hlua (polypropylene hlua)yog qhov siv dav tshaj plaws. Nws paub txog nws qhov kev tiv thaiv hluav taws zoo heev, lub zog tensile, thiab kev ruaj khov tshuaj lom neeg. PP filler hlua feem ntau siv rau hauv cov xov hluav taws xob, cov xov tswj, cov xov sib txuas lus, thiab cov xov ntaub ntawv. Ua tsaug rau nws cov qauv sib dua, lub zog siab, yooj yim ua, thiab sib xws nrog ntau yam khoom siv tsim cable, nws tau dhau los ua qhov kev daws teeb meem tseem ceeb hauv kev siv cable filling. Ib yam li ntawd, cov yas filler strips ua los ntawm cov yas rov ua dua tshiab muab kev ua tau zoo tshaj plaws ntawm tus nqi qis dua, ua rau lawv zoo tagnrho rau cov xov hluav taws xob nruab nrab thiab qis thiab cov chaw tsim khoom loj.
Cov khoom siv ntuj tsim xws li jute, xov paj rwb, thiab hlua ntawv tseem siv rau qee qhov kev siv uas pheej yig, tshwj xeeb tshaj yog rau cov xov hlau pej xeem. Txawm li cas los xij, vim lawv nqus tau dej noo ntau thiab tsis kam pwm thiab xeb, lawv maj mam hloov los ntawm cov khoom siv hluavtaws xws li PP filler hlua, uas muaj kev tiv thaiv dej zoo dua thiab siv tau ntev.
Rau cov qauv cable uas xav tau kev ywj pheej siab - xws li cov cables ywj pheej thiab cov cables rub saw - cov roj hmab filler strips feem ntau raug xaiv. Lawv cov elasticity thiab cushioning zoo heev pab nqus cov kev co sab nraud thiab tiv thaiv cov qauv conductor sab hauv.
Hauv cov chaw kub siab xws li cov xov hluav taws uas tiv taus hluav taws, cov xov hlau khawb av, thiab cov xov hlau qhov av, cov ntaub ntawv sau xov hlau yuav tsum ua tau raws li cov qauv hluav taws kub thiab cov qauv tiv taus kub. Cov hlua iav fiber ntau siv dav hauv cov xwm txheej zoo li no vim lawv qhov kev ruaj khov thermal zoo heev thiab muaj peev xwm txhawb nqa cov qauv. Cov hlua asbestos feem ntau raug tshem tawm vim muaj kev txhawj xeeb txog ib puag ncig thiab kev noj qab haus huv thiab tau hloov los ntawm cov kev xaiv muaj kev nyab xeeb dua xws li cov khoom siv uas tsis muaj pa luam yeeb tsawg, tsis muaj halogen (LSZH), cov khoom siv silicone, thiab cov khoom siv inorganic.
Rau cov cables optical, cov cables hybrid power-optical, thiab cov cables hauv qab dej uas xav tau kev ua haujlwm zoo hauv dej, cov khoom siv txhaws dej yog qhov tseem ceeb. Cov ntaub nplaum thaiv dej, cov xov thaiv dej, thiab cov hmoov nqus dej zoo heev tuaj yeem o sai thaum kov dej, ua kom kaw cov kev nkag mus thiab tiv thaiv cov fibers sab hauv lossis cov xov hlau los ntawm kev puas tsuaj los ntawm dej noo. Hmoov talcum kuj tseem siv tau ntawm cov txheej rwb thaiv tsev thiab cov txheej sheath kom txo qhov sib txhuam, tiv thaiv kev lo, thiab txhim kho kev ua haujlwm zoo.
Nrog rau kev tsom mus rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov, ntau cov khoom siv cable filling uas zoo rau ib puag ncig tau raug siv rau hauv cov teb xws li cov xov hlau tsheb ciav hlau, cov xov hlau hauv tsev, thiab cov chaw khaws ntaub ntawv. Cov hlua PP LSZH uas tsis kub hnyiab, cov khoom siv silicone fillers, thiab cov yas ua npuas dej muab ob qho txiaj ntsig ib puag ncig thiab kev ntseeg siab ntawm cov qauv. Rau cov qauv tshwj xeeb xws li cov xov hlau xoob xoob, cov xov hlau fais fab optical, thiab cov xov hlau coaxial, cov khoom siv gel-based filling-xws li cov khoom siv optical cable filling (jelly) thiab cov khoom siv silicone roj-based-feem ntau siv los txhim kho kev ywj pheej thiab kev tiv thaiv dej.
Xaus lus, kev xaiv cov khoom siv sau cable kom raug yog qhov tseem ceeb rau kev nyab xeeb, kev ruaj khov ntawm cov qauv, thiab lub neej ua haujlwm ntawm cov cables hauv cov chaw siv nyuaj. Ua tus kws tshaj lij ntawm cov khoom siv raw cable, ONE WORLD cog lus tias yuav muab ntau yam kev daws teeb meem sau cable ua haujlwm siab, suav nrog:
PP filler rope (polypropylene rope), yas filler strips, iav fiber ropes, roj hmab filler strips,cov ntaub thaiv dej, cov hmoov thaiv dej,cov xov uas thaiv dej, cov khoom siv fillers uas tsis muaj pa luam yeeb tsawg uas tsis muaj halogen thiab tsis ua rau ib puag ncig puas tsuaj, cov khoom sib xyaw ua ke rau cov cable optical, cov khoom siv roj hmab silicone, thiab lwm yam khoom siv tshwj xeeb uas ua los ntawm gel.
Yog tias koj xav tau cov ntaub ntawv ntxiv txog cov ntaub ntawv sau cable, thov hu rau ONE WORLD. Peb npaj txhij los muab cov lus qhia txog cov khoom lag luam thiab kev txhawb nqa kev txawj ntse rau koj.
