1 、 Daim tawv nqaij: PVC lossis nplaim taws rov zoo PVC feem ntau siv rau sab hauv tsev kho qhov muag cable. Cov tsos yuav tsum du, kaj lug, hloov tau thiab yooj yim rau tev tawm. Qhov saum npoo tiav ntawm qhov tsis zoo kho qhov muag cable tsis zoo, thiab nws yog qhov yooj yim kom ua raws li cov tes tsho nruj thiab aramid fiber ntau sab hauv.
PE sheath ntawm cov hluav taws xob sab nraum zoov cable yuav tsum yog ua los ntawm cov qib zoo dub polyethylene, nrog du, ci, hnav tuab thiab tsis muaj npuas me me. Cov tawv nqaij ntawm inferior optical cable feem ntau yog ua los ntawm cov khoom siv rov ua dua tshiab, tuaj yeem txuag tus nqi ntau. Cov tawv nqaij ntawm cov qhov muag hluav taws xob tsis zoo, vim tias muaj ntau qhov tsis zoo nyob rau hauv cov ntaub ntawv raw, muaj ntau lub qhov dej me me rau ntawm daim tawv nqaij ntawm qhov kho qhov muag cable, uas yuav tawg thiab dej hauv lub sijhawm ntev.
2 、 Optical fiber: cov khoom siv kho qhov muag fiber ntau tsis tu ncua feem ntau siv A-theem fiber ntau los ntawm cov chaw ua haujlwm loj, thaum qee tus nqi qis thiab qis dua optical cable feem ntau siv C-theem thiab d-qib optical fiber ntau thiab kev ua cov fiber ntau kho qhov muag nrog cov keeb kwm tsis paub. Cov khoom siv kho qhov muag no feem ntau ua rau plhaw thiab plooj vim lawv cov peev txheej nyuaj thiab lub sijhawm siv sijhawm ntev, thiab multimode optical fibers feem ntau xyaw nrog ib hom fiber ntau kho qhov muag. Txawm li cas los xij, cov chaw ua haujlwm me me feem ntau tsis muaj cov khoom tsim nyog tshawb nrhiav kom paub txog cov fiber ntau kho qhov ua tau zoo. Vim tias lub qhov muag liab qab tsis tuaj yeem txheeb xyuas qhov zoo li no fiber ntau, qhov teeb meem tshwm sim hauv kev tsim kho yog: nqaim bandwidth, luv xa mus deb; tsis sib npaug tuab, tsis muaj peev xwm sib npaug nrog tus Tsov tus tw fiber; tsis muaj qhov yooj ntawm kho qhov muag fiber, tawg thaum cua.
3 、 Reinforcing steel hlau: cov hlau xaim ntawm sab nraum zoov kho qhov muag cable ntawm lub chaw tsim tshuaj paus tsis tu ncua yog phosphated, thiab saum npoo yog grey, yog li cov hlau xaim tsis nce hydrogen poob, xeb, thiab muaj lub zog siab. Qhov ua tsis tau zoo cable feem ntau hloov los ntawm nyias hlau hlau lossis txhuas hlau. Cov cim txheej txheem yog yooj yim heev - lub ntsej muag zoo li dawb, thiab nws tuaj yeem yog khoov duav thaum pinched hauv tes. Lub hydrogen poob ntawm cov hluav taws xob cable tsim tawm nrog xws li cov hlau xaim yog loj. Tom qab lub sijhawm ntev, ob qhov kawg ntawm lub thawv fiber ntau yuav xeb thiab ua kom tawg.
4 、 Steel muaj cov cuab yeej: cov chaw tsim khoom lag luam niaj hnub siv cov ntawv ntev ntev los ntawm kev coj los ua ke nrog cov txheej txheem xeb ntawm ob sab, thiab cov ua tsis tau zoo siv cable siv cov ntawv hlau zoo tib yam, feem ntau tsuas yog ib sab tau kho nrog kev kho xeb.
Tsib, xoob casing: optical fiber cable xoob fiber ntau tes tsho yuav tsum ua los ntawm PBT cov khoom, kom lub zog casing siab, tsis muaj deformation, los tiv thaiv kev laus. Qhov ua kom zoo me me siv cable feem ntau siv PVC ua lub tes tsho. Txoj kab uas hla ntawm lub tes tsho yog nyias heev, thiab nws yuav zoo nkauj thaum pinched los ntawm txhais tes, uas zoo li me ntsis zoo li lub straw peb haus.
6 、 Fiber muab tshuaj: cov fiber ntau muab tso rau hauv qhov kho qhov muag sab nraum zoov tuaj yeem tiv thaiv qhov oxidation ntawm fiber ntau kho qhov muag. Vim tias muaj kev ya raws, muaj ob peb cov tshuaj fiber ntau siv nyob rau hauv cov qib fiber ntau kho qhov muag, uas cuam tshuam loj rau kev pab cuam lub neej ntawm lub fiber ntau.
7 、 Aramid: tseem hu ua Kevlar, yog ib hom ntawm cov muaj zog tshuaj lom neeg muaj tshuaj, uas tam sim no feem ntau siv hauv kev lag luam tub rog. Lub kaus mom cov tub rog thiab phom tsho mos txwv yog ua los ntawm cov khoom siv no. Tam sim no, tsuas yog DuPont thiab Aksu hauv Netherlands tuaj yeem tsim nws, thiab tus nqi kwv yees li 30 lab tons. Sab hauv tsev cov hluav taws xob cable kydl_ Syey thiab ADSS ob leeg siv cov xov aramid li kev txhawb nqa. Vim tias tus nqi ntawm aramid cov xov paj yog qhov siab, qhov dav ntawm sab nraud ntawm sab hauv tsev hluav taws xob cable feem ntau yog heev nyias, yog li ob peb aramid yarns tuaj yeem siv los txuag tus nqi. Txoj kab xaim no yooj yim tawg thaum nws muab tso rau ntawm cov yeeb nkab. ADSS cable raws li qhov dav, cua nrawm ib ob mus txiav txim siab siv aramid fiber ntau hauv kab hluav taws xob, feem ntau tsis twv txiav cov fab.
