1, Daim tawv nqaij: Sab hauv kho qhov muag cables feem ntau yog ua los ntawm polyvinyl chloride los yog nplaim hluav taws-retardant polyvinyl chloride. Qhov saum npoo yuav tsum du, ci, yoog raws, thiab yooj yim rau tev tawm. Cov kab hluav taws xob kho qhov muag tsis zoo muaj qhov tsis zoo ntawm qhov chaw tiav thiab nws yooj yim rau kev ua kom nruj nruj thiab aramid sab hauv.
PE sheath ntawm sab nraum zoov kho qhov muag cables yuav tsum tau ua los ntawm high-zoo dub polyethylene, nrog ib tug du, ci, uniform thickness, thiab tsis muaj npuas me me tom qab tsim cable. Cov tawv nqaij sab nrauv ntawm cov khoom siv kho qhov muag tsis zoo feem ntau yog tsim los ntawm cov khoom siv rov ua dua tshiab, uas tuaj yeem txuag tau ntau tus nqi. Cov tawv nqaij sab nrauv ntawm cov khoom siv kho qhov muag no tsis yog du, thiab muaj ntau yam impurities hauv cov khoom siv raw. Cov tawv nqaij sab nrauv ntawm cov khoom siv kho qhov muag muaj ntau lub qhov me me, uas tuaj yeem tawg thiab tau dej dhau sijhawm.
2, Fiber optic cable: Tsis tu ncua fiber optic cable ntau lawm lag luam feem ntau siv A-qib fiber ntau cores los ntawm cov chaw tsim khoom loj. Qee tus nqi qis thiab tsis zoo fiber ntau optic cables feem ntau siv C-qib thiab D-qib fiber ntau optic cables, nrog rau smuggled fiber optic cables uas tsis paub keeb kwm. Cov fiber ntau optic cables no feem ntau dhau los ua ntub dej thiab tsis muaj xim vim lawv qhov chaw nyuaj thiab siv sijhawm ntev. Tsis tas li ntawd, ib hom fiber ntau optic cables feem ntau yog tov nrog multimode fiber optic cables, thiab cov chaw tsim khoom me feem ntau tsis muaj cov khoom siv ntsuas tsim nyog los txiav txim siab txog qhov zoo ntawm fiber ntau optic cables. Vim qhov tsis muaj peev xwm paub qhov txawv ntawm cov fibers kho qhov muag nrog qhov muag liab qab, cov teeb meem tshwm sim thaum lub sij hawm tsim kho yog: nqaim bandwidth thiab kev sib kis luv luv; Tsis sib npaug thickness thiab tsis muaj peev xwm txuas nrog tus Tsov tus tw fibers; Fiber optic tsis muaj qhov yooj yim thiab tawg yooj yim thaum coiled.
3, Strengthening Steel Hlau: Cov hlau hlau rau sab nraum zoov kho qhov muag cables uas tsim los ntawm cov tuam txhab raug cai yog phosphatized thiab muaj qhov grey nto. Hom steel hlau no tsis ua rau muaj kev puas tsuaj rau hydrogen, xeb, thiab muaj zog siab tom qab siv los ua ib lub cable. Cov khoom siv kho qhov muag tsis zoo yog feem ntau hloov nrog cov hlau zoo lossis txhuas hlau, thiab cov txheej txheem qhia tau yooj yim - qhov saum npoo yog dawb thiab tuaj yeem khoov tau yooj yim thaum tuav hauv tes. Cov kab hluav taws xob kho qhov muag uas tsim los ntawm cov hlau zoo li no muaj hydrogen poob siab, thiab dhau sijhawm, ob qhov kawg ntawm lub thawv dai fiber ntau optic yuav xeb thiab tawg.
4, Hlau Armor: Cov tuam txhab tsim khoom raug cai siv cov hlua khi ntev ntev nrog ob sab los tiv thaiv xeb, thaum cov khoom siv kho qhov muag tsis zoo siv cov ntawv hlau zoo tib yam, feem ntau tsuas yog ib sab tau kho nrog xeb.
5, Cov raj xoob: PBT cov khoom siv yuav tsum tau siv rau cov raj xoob ntawm cov khoom siv kho qhov muag tau teeb tsa hauv cov kab hluav taws xob kho qhov muag, uas muaj lub zog siab, tsis muaj deformation thiab kev laus ua haujlwm. Cov khoom siv kho qhov muag tsis zoo feem ntau yog siv PVC ua lub casing, uas muaj ib txoj kab uas hla sab nraud thiab tuaj yeem flattened nrog ib tug pinch, zoo ib yam li cov quav cab uas peb siv los haus dej haus.
6, Roj muab tshuaj: Roj muab tshuaj feem ntau suav nrog fiber ntau muab tshuaj thiab cable muab tshuaj. Nyob rau hauv ib txwm muaj xwm txheej, fiber ntau muab tshuaj txhuam yuav tsum sau tag nrho cov raj xoob, thaum muab tshuaj txhuam cable yuav tsum sau txhua qhov sib txawv ntawm cov tub ntxhais kho qhov muag hauv qab lub siab. Muaj ntau txoj hauv kev los sau cov fiber ntau muab tshuaj txhuam ib nrab los yog tsawg dua, thaum qee qhov muab tshuaj txhuam cable tsuas yog siv cov txheej txheem sab nraud ntawm cov tub ntxhais cable, thaum lwm tus tsis sau nruab nrab ntawm ob qhov kawg ntawm cov khoom siv kho qhov muag. Qhov no yuav ua rau muaj kev tiv thaiv tsis zoo ntawm fiber ntau optical, cuam tshuam kev sib kis tau zoo xws li fiber ntau attenuation, thiab kev ua haujlwm tsis zoo ntawm cov dej tsis zoo uas tsis ua raws li cov qauv hauv tebchaws. Thaum cov kab hluav taws xob kho qhov muag tsis pom dej ntws tawm, nws yuav ua rau tag nrho qhov txuas raug puas vim dej to. Raws li qhov xwm txheej ib txwm muaj, txawm tias muaj qhov tsis sib haum xeeb, tsuas yog ib feem ntawm cov seepage yuav tsum tau kho, thiab tsis tas yuav pib dua. Lub teb chaws tus qauv yuav tsum muaj kev ua tau zoo ntawm cov dej tsis zoo ntawm peb metres ntawm optical cable, ib lub meter ntawm cov kab dej siab, thiab tsis muaj dej xau rau 24 teev. Yog tias siv roj tsis zoo, cov teeb meem saum toj no kuj tuaj yeem tshwm sim, thiab cov roj thixotropy tsis zoo tuaj yeem ua rau me ntsis khoov ntawm cov khoom siv kho qhov muag, uas ua rau tsis tsim nyog kis tau tus yam ntxwv ntawm tag nrho cov txuas; Yog hais tias cov tshuaj pleev yog acidic, nws yuav hnov mob nrog cov ntaub ntawv hlau nyob rau hauv lub optical cable kom precipitate hydrogen molecules, thiab lub attenuation ntawm cov fiber ntau optical yuav sai sai thaum nws ntsib H, ua rau tag nrho cov kis tau tus mob yuav cuam tshuam.
7, Aramid, tseem hu ua Kevlar, yog cov tshuaj fiber ntau muaj zog uas feem ntau siv hauv kev lag luam tub rog. Cov kaus mom hlau tub rog thiab cov tsho tiv thaiv mos txwv yog ua los ntawm cov khoom siv no. Los ntawm 2013, tsuas yog DuPont thiab Aksu hauv Netherlands tuaj yeem tsim tau ntawm tus nqi kwv yees li 300000 tons. Cov kab hluav taws xob sab hauv tsev thiab lub zog hluav taws xob hluav taws xob hluav taws xob hluav taws xob (ADSS) yog ob qho tib si ntxiv nrog cov xov paj aramid. Vim yog tus nqi siab ntawm aramid, cov khoom siv hluav taws xob hauv tsev tsis zoo feem ntau muaj qhov nyias nyias, uas tuaj yeem txuag cov nqi los ntawm kev siv cov aramid tsawg dua. Hom kho qhov muag cable no yooj yim tawg thaum threading los ntawm cov kav dej. ADSS optical cables feem ntau tsis twv kom txiav cov ces kaum vim tias tus nqi ntawm aramid siv nyob rau hauv cov cables yog txiav txim raws li ncua sij hawm thiab cua ceev ib ob.
8, Dej thaiv daim kab xev: Dej thaiv daim kab xev los yog xov paj siv nyob rau hauv optical cables muaj zog nqus dej ua tau zoo los ntawm cov uniformly faib siab absorbing resin nyob rau hauv cov khoom. Nyob rau hauv kev sib xyaw ua ke ntawm kev tso dej siab, kev sib raug zoo, thiab cov roj hmab elasticity, cov dej siab absorbing resin tuaj yeem nqus dej sai sai ntau zaus nws qhov hnyav. Tsis tas li ntawd, ib zaug cov dej thaiv cov hmoov tau ntsib dej, nws yuav nthuav tawm cov gel tam sim ntawd. Nyob rau lub sijhawm no, txawm tias lub zog siv rau nws npaum li cas, cov dej yuav tsis raug nyem tawm. Yog li ntawd, los ntawm kev npog cov tub ntxhais cable nrog cov dej thaiv daim kab xev uas muaj cov khoom siv absorbent, yog tias cov phab ntsa sab nrauv ntawm cov khoom siv kho qhov muag puas lawm, cov khoom siv siab absorbent nyob rau hauv lub qhov txhab yuav nthuav dav thiab ua kom muaj kev sib khi, uas tuaj yeem tiv thaiv dej los ntawm kev nkag mus. mus rau qhov tsawg kawg nkaus. Cov khoom siv kho qhov muag tsis zoo feem ntau yog siv cov ntaub ntawv tsis-woven los yog daim ntawv kab xev, thiab ib zaug cov tawv nqaij ntawm cov cable puas lawm, qhov tshwm sim yuav loj heev.
