1. Outer sling:
1. Cov txheej txheem sab hauv ntawm cov khoom siv kho qhov muag hauv tsev feem ntau yog ua los ntawm polyvinyl chloride (PVC) lossis nplaim hluav taws xob polyethylene lossis polyurethane (LSZH). Lub npog sab nrauv yog du, ci iab, yoog raws thiab yooj yim rau tev. Sab nrauv ntawm cov kab hluav taws xob qis qis muaj qhov ua tiav tsis zoo thiab nws yooj yim ua rau lub tes tsho nruj thiab aramid fibers.
2. Lub plhaub sab nraud ntawm cov khoom siv kho qhov muag sab nraum zoov yuav tsum tau ua los ntawm cov khoom siv zoo dub polyethylene (HDPE, MDPE). Thaum lub cable yog tsim, lub txheej sheath yuav tsum du, ci, ntawm uniform thickness thiab tsis muaj npuas. Cov txheej txheej ntawm cov kab hluav taws xob qis qis yog tsim los ntawm cov khoom siv rov ua dua tshiab. Cov txheej txheej ntawm cov kab hluav taws xob qis qis yog qhov ntxhib vim tias muaj ntau yam impurities (lime plua plav) hauv cov ntaub ntawv raw, uas tshwm sim nws tus kheej li ntau qhov me me ntawm cov ntaub qhwv sab nraud ntawm Optical Cable. Yog hais tias lub sab nrauv ntawm lub optical cable yog khoov ob peb zaug, nws yuav puas. Nws puv dawb. Tom qab tso qhov kho qhov muag cable rau ib lub sijhawm, lub plhaub sab nrauv yuav tawg thiab dej yuav xau.
2. Fiber optic:
Cov neeg tsim khoom siv kho qhov muag yuav siv Class A fiber cores los ntawm cov tuam txhab loj. Tus nqi qis thiab cov khoom siv kho qhov muag tsis zoo feem ntau siv cov chav kawm C, chav kawm D optical fibers thiab cov khoom siv kho qhov muag tsis paub txog keeb kwm, cov khoom siv kho qhov muag no muaj qhov chaw nyuaj thiab tau tawm ntawm lub Hoobkas ntev. Lawv feem ntau humid. thiab discolored, thiab multimode optical fibers feem ntau tov nrog singlemode optical fibers. Feem ntau, cov chaw tsim khoom me tsis muaj cov cuab yeej ntsuas tsim nyog thiab tsis tuaj yeem txiav txim siab qhov zoo ntawm cov fibers optical. Cov fibers optical no tsis tuaj yeem txheeb xyuas qhov muag liab qab. Cov teeb meem tshwm sim thaum lub sij hawm tsim kho yog: lub bandwidth yog nqaim heev thiab qhov kis tau tus mob yog luv; lub thickness tsis sib npaug thiab tsis tuaj yeem txuas nrog pigtail; Optical fiber tsis muaj qhov yooj yim thiab yooj yim tawg thaum coiled.
3. Reinforced steel hlau:
Cov hlau xaim ntawm cov kab hluav taws xob sab nraum zoov los ntawm cov chaw tsim khoom lag luam yog phosphate thiab muaj qhov grey nto. Hom steel hlau no tsis ua kom cov hydrogen poob tom qab xaim, tsis xeb, thiab muaj lub zog siab. Substandard optical cables yog hloov los ntawm nyias hlau hlau los yog txhuas hlau. Txoj kev txheeb xyuas yog tias nws muaj xim dawb thiab tuaj yeem khoov ntawm lub siab thaum tuav hauv tes. Cov kab hluav taws xob kho qhov muag ua los ntawm hom hlau hlau no yuav ua rau muaj kev puas tsuaj ntxiv rau yav tom ntej, thiab dhau sijhawm, ob qhov kawg ntawm lub thawv fiber ntau yuav xeb thiab tawg.
4. Armored Steel Belt:
Cov tuam txhab tsim khoom ib txwm siv ob-sided brushed anti-xeb yas coated longitudinally qhwv steel strips. Cov kab hluav taws xob hauv qab yog ua los ntawm cov ntawv hlau zoo tib yam, thiab feem ntau tsuas yog ib sab tau kho kom tsis txhob xeb.
5. Fiber optic casing:
Lub raj xoob uas qhwv cov fiber ntau hauv qhov kho qhov muag yuav tsum tau ua los ntawm cov khoom siv PBT. Lub raj ua los ntawm cov khoom siv no muaj lub zog siab, tsis deform thiab tiv thaiv kev laus. Hauv qab optical cable casings feem ntau yog ua los ntawm PVC cov ntaub ntawv. Sab nraud ntawm lub plhaub yog nyias thiab mos, thiab lawv flatten thaum pinched los ntawm tes. Lawv tsis txawv ntawm cov dej haus straws thiab tsis tuaj yeem tiv thaiv fiber ntau zoo.
6. Fiber tshuaj pleev:
Cov fiber ntau muab tshuaj ntawm cov khoom siv kho qhov muag sab nrauv tuaj yeem tiv thaiv cov nyiaj streaks, hydrogen poob, thiab txawm tias tawg ntawm fiber ntau optical los ntawm noo noo. Cov tshuaj fiber ntau me me yog siv rau hauv cov kab hluav taws xob qis qis thiab qee cov npuas tuaj yeem pom ntawm qhov muag liab qab. Los yog siv cov tshuaj fiber ntau tsis zoo, uas ua rau lub neej luv ntawm fiber ntau optic cables.
7. Aramid:
Kuj hu ua Kevlar, nws yog cov tshuaj tiv thaiv kab mob siab uas tam sim no siv ntau dua hauv kev lag luam tub rog; Tam sim no, aramid fiber ntau ntawm kev ua lag luam feem ntau yog los ntawm American hom DuPont. Ob qho tib si hauv tsev kho qhov muag cables thiab aerial fais fab kho qhov muag cables (ADSS) siv aramid yarn li qhov cuab lub zog. Vim yog tus nqi siab ntawm aramid (200,000 yuan / ton), cov kab hluav taws xob sab hauv tsev tsis zoo feem ntau muaj cov kab uas hla nyias nyias, uas tuaj yeem txuag nqi los ntawm kev txo qee cov xov paj aramid. Hom kab hluav taws xob kho qhov muag no tawg yooj yim thaum hla cov yeeb nkab. .
8. Cable muab tshuaj:
Cov fiber ntau muab tshuaj txhuam ntawm cov khoom siv kho qhov muag sab nrauv yog khi rau sab nraud ntawm lub tes tsho fiber ntau los tiv thaiv cov kab hluav taws xob los ntawm kev ya raws. High-quality cable muab tshuaj txhuam sib tov sib xyaw thiab tsis sib cais tom qab siv ntev. Nyob rau hauv cov khoom siv kho qhov muag tsis zoo, cov tshuaj fiber ntau yuav evaporate los yog cov filling yuav tsis txaus, uas yuav cuam tshuam rau kev ua haujlwm tsis zoo ntawm fiber ntau optic cable.
