Fiber Cable Outer Sheath Cov ntaub ntawv thiab yuav xaiv li cas?
Lub luag haujlwm tseem ceeb ntawm cov fiber ntau cable sab nrauv yog los tiv thaiv cov fibers hauv qhov kho qhov muag los ntawm kev puas tsuaj sab nraud.
Kev xav tau
Yog li cov khoom siv ntawm fiber ntau optic cable sab nrauv sheath yuav tsum muaj peev xwm tiv taus lub hnub thiab nag, thiab tsis tawg vim hluav taws xob ultraviolet. Nyob rau tib lub sijhawm, nws yuav tsum muaj qee qhov tensile thiab flexural peev xwm, thiab tuaj yeem tiv taus kev puas tsuaj thaum siv thiab tshuaj lom neeg corrosion hauv kev siv engineering.
Common Sheath Materials
Ntau cov ntaub ntawv cable sab nraud yog PVC, PE, LSZH, AT thiab cov ntaub ntawv pov thawj nas.
PVC
PVC yog siv dav siv fiber ntau optic cable sab nrauv sheath khoom. Nws muaj kev ua tau zoo, cov tshuaj tiv thaiv zoo thiab huab cua tsis kam, tus nqi qis, tsis tshua muaj nplaim taws, thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub sijhawm. Txawm li cas los xij, PVC sheathed optical cable yuav tsim cov pa taws hnyav thaum hlawv, uas tsis yog ib puag ncig zoo.
PE
Polyethylene sheath cov ntaub ntawv tsis muaj ntxhiab, tsis muaj tshuaj lom, zoo li siv quav ciab. Nws muaj qhov kub thiab txias tsis kam (qhov kub qis tshaj tuaj yeem ncav cuag -100 ~ -70} degree), tshuaj lom neeg ruaj khov, thiab tuaj yeem tiv taus cov kua qaub thiab alkalis feem ntau (tsis tiv taus oxidation). Nws yog insoluble nyob rau hauv cov kuab tshuaj nyob rau hauv lub chav tsev kub, tsis muaj dej nqus thiab zoo heev hluav taws xob rwb thaiv tsev.
Vim tias qhov ceev qis, huab cua zoo permeability, cov rwb ua tau zoo heev thiab UV tiv thaiv PE fiber ntau cable, feem ntau nws siv nyob rau sab nraum zoov ib puag ncig. Raws li qhov ceev ntawm PE fiber cable sab nrauv sheath, kuj tseem muaj MDPE (nruab nrab ntom) thiab HDPE (siab ceev).
LSZH
LSZH (tsis tshua muaj pa luam yeeb xoom halogen) yog cov khoom siv hluav taws xob hluav taws xob uas muaj cov khoom siv tsis zoo (txhuas hydroxide, magnesium hydroxide). LSZH sheathed fiber optic cable tsis tsuas yog dilute lub concentration ntawm combustible cov ntaub ntawv, tab sis kuj nqus cov cua kub generated los ntawm combustion, thiab nyob rau tib lub sij hawm tsim ib tug tsis-combustible oxygen barrier.
LSZH fiber ntau optic cable muaj cov nplaim hluav taws zoo heev, cov pa luam yeeb me me thaum lub sij hawm sib xyaw, tsis muaj cov pa luam yeeb dub, tsis muaj corrosive gas khiav, zoo tensile zog, roj kuj thiab softness, zoo heev kub siab ua hauj, haum rau ib puag ncig nrog nplaim retardant yuav tsum tau thiab tiv taus voltage. . Qhov tsis zoo yog tias LSZH sheath yooj yim tawg.
AT
Cov txheej txheej ntawm cov khoom siv kho qhov muag ntawm AT tuaj yeem tau txais los ntawm kev ntxiv cov khoom ntxiv rau PE. Hom sheath no muaj kev ua tau zoo los tiv thaiv kev ua haujlwm, yog li cov khoom siv kho qhov muag feem ntau siv nyob rau hauv qhov chaw muaj hluav taws xob hluav taws xob siab xav tau cov ntaub ntawv ntawm AT.
Anti-Rodent
Lwm cov khoom siv kho qhov muag cable sheathing yog cov khoom siv los tiv thaiv nas, uas yog siv rau cov kab hluav taws xob kho qhov muag nteg hauv qhov av thiab cov haujlwm hauv av. Lub tshuab tau muab faib ua tshuaj tiv thaiv thiab kev tiv thaiv lub cev. Ntawm lawv, kev tiv thaiv lub cev yog ib txoj hauv kev zoo dua, thiab cov xov paj aramid thiab cov khoom siv hlau tuaj yeem siv los tiv thaiv nas tom.
Anti-Flame
Thaum siv cov fiber ntau optic hauv cov mines lossis lwm yam kev nyab xeeb ua ntej ib puag ncig, qhov zoo ntawm cov nplaim hluav taws xob ntawm fiber ntau optic cable yog qhov tseem ceeb. Flame-retardant optical cable yog cov nplaim hluav taws kub-retardant polyethylene sheath khoom siv cov khoom siv kho qhov muag zoo tib yam polyethylene sheath khoom, kom cov khoom siv kho qhov muag muaj cov nplaim hluav taws.
Xaiv Fiber Cable Outer Sheath
