Nyob sab hauv tsev kho qhov muag tau siv hauv cov txheej txheem cabling. Vim yog ntau yam xws li kev tsim kho ib puag ncig thiab cov teeb meem kev teeb tsa, tus tsim ntawm cov xov tooj sab hauv tau ua ntau dua. Cov ntaub ntawv siv rau cov khoom siv kho tshiab thiab cov xaim yog ntau haiv neeg, nrog cov tshuab kho tshuab thiab kho qhov muag tau hais txog txawv. Hom Kev Tawm Tsam Sab Hauv Tsev Kho Yog suav nrog ib leeg-tub ntxhais Ceg Cables, tsis-bricled cables, thiab cabled cabled. Niaj hnub no, ib lub ntiaj teb yuav tsom rau ib qho ntawm feem ntau hom brounded optical cable: GJFJV.
GJFJv Nyob Sab Hauv Kho Optical Cable
1. Cov qauv sib xyaw
Cov qauv kev lag luam qauv rau cov xov tooj sab hauv tsev yog GJFJV.
GJ - Kev Sib Txuas Lus Sab Hauv Tsev Kho Khoom Siv Kho Mob
F - Tsis yog xim hlau txhawb cov khoom siv
J - Tawv-ntas Ovenical fiber ntau qauv
V - polyvinyl chloride (PVC) sheath
Nco tseg: Rau cov ntaub ntawv pov thawj, "H" sawv ntsug rau cov pob zeb luam yeeb tsawg, thiab "u" sawv rau polyurethane sheath.
2. Nyob sab hauv kho qhov muag cable-seem
Cov ntaub ntawv muaj pes tsawg leeg thiab cov yam ntxwv
1. Coated optical fiber (muaj ntawm cov roj muaj fiber ntau thiab txheej sab nraud txheej)
Lub ntsuas hluav taws xob kho qhov muag yog ua los ntawm cov khoom sillica, thiab cov qauv cladding taub yog 125 μm. Lub tub ntxhais lub taub rau ib-hom (B1.3) yog 8.6-9.5 μm, thiab rau Multi-hom (OM1 A1B) yog 62.5 μm. Cov tub ntxhais txoj kab uas cov tub ntxhais rau ntau hom OM2 (A6A.1), om3 (AN1A.2), OM4 (OM5 (AN1A.4 yog 50 μm.
Thaum lub sij hawm kos duab ntawm lub khob txheej txheem ntawm cov txheej txheem kho qhov muag, ib txheej ntawm cov txheej elastic siv tau siv cov roj av ulteriolet los tiv thaiv kev paug los ntawm hmoov av. Cov txheej no yog ua los ntawm cov ntaub ntawv xws li acrylate, silicone roj hmab, thiab nylon.
Txoj haujlwm ntawm cov txheej yog txhawm rau tiv thaiv cov tshuaj lom fiber ntau saum npoo av, roj av, thiab txhim kho cov microbend kev ua haujlwm ntawm cov fiber, yog li txo qis dua khoov kev poob.
Cov txheej tuaj yeem xim tuaj yeem muaj xim, thiab cov xim yuav tsum ua raws GB / T 6995.2 (Xiav, xim av, xim daj, xim paj yeeb, lossis cyan ntsuab). Nws tseem tuaj yeem ua tiav cov xeeb ceem raws li ntuj.
2. Cov Txheej Txiav
Cov ntaub ntawv: Ib puag ncig phooj ywg, nplaim taws-retardant polyvinyl chloride (PVC),tsawg pa luam yeeb halogen-dawb (lszh) polyolefin, Ofnr-rated nplaim-retardant cable, ntawmnp-rated nplaim-retardant cable.
Muaj nuj nqi: nws txuas ntxiv tiv thaiv cov tshiab feelers, kom ua lawv cov kev hloov kho kom haum rau ntau yam. Nws muaj kev tsis kam mus nro, compression, thiab khoov, thiab tseem muab dej thiab noo noo tsis kam.
Siv: cov txheej nruj sib zog tuaj yeem ua xim xim-coded rau kev txheeb xyuas, nrog cov xim xim suav nrog GB / T 6995.2 Cov Qauv. Rau cov qauv uas tsis yog tus qauv, cov xim xim lossis cov khoom siv dots.
3. Kev txhawb nqa cov Cheebtsam
Khoom siv:Aramid xov, Poly Poly (P-Phenylene Terephthalamide), ib hom tshiab ntawm cov tshuab hluav taws xob siab hluavtaws fiber ntau. Nws muaj cov khoom zoo heev xws li ultra-siab modulus, lub siab kub ua rau, lub teeb ci, rwb thaiv tsev, lub neej ntev. Thaum ntau dua txias, nws tswj hwm kev ruaj khov, nrog tus nqi qis heev, tsawg kawg nkaus shrinkage tus nqi, tsawg heev creep, thiab siab hloov cov cua kub. Nws tseem muaj cov peev txheej tiv taus thiab tsis muaj zog, ua rau nws muaj qhov zoo tshaj plaws cov khoom siv rau cov khoom siv kho qhov muag.
Muaj nuj nqi: aramid xov yog tus tseem ceeb nyob ib ncig ntawm Cable Tensile thiab siab ua rau muaj zog, kev ruaj khov stability, thiab tshuaj ruaj khov.
Cov yam ntxwv no ua kom cov cable kis kev ua tau zoo thiab kev pabcuam lub neej. Aramid tseem muaj feem ntau siv hauv kev tsim cov ntawv faib tawm thiab parachutes vim nws lub zog zoo tshaj plaws.
4. Sab nraud sheath
Cov ntaub ntawv: Cov nplaim hluav taws kub tsis zoo-retardant polyolefin (lszh), polyvinyl chloride (PVC), lossis ONNR / Retardant cables. Lwm cov ntaub ntawv txau tuaj yeem siv tau raws li cov neeg siv khoom yuav tsum muaj. Tsawg tus luam yeeb halogen-dawb polyolefin yuav tsum ua tau raws li YMS13 cov qauv; Polyvinyl chloride yuav tsum ua raws li GB / T8815-2008 rau cov ntaub ntawv mos muag; Thermoplasts polyurethane yuav tsum tau ntsib YD / T3431-2018 qauv rau thermoplastic polyurethane elastomers.
Muaj nuj nqi: Cov ntaub ntawv sab nraud muab kev tiv thaiv ntxiv rau cov khoom siv kho kho qhov muag, ua kom lawv tuaj yeem hloov kho cov chaw nruab rau ntau yam. Nws tseem muab kev tsis kam rau nro, compression, thiab khoov, thaum muab dej thiab noo noo tsis kam. Rau cov ntaub ntawv hluav taws kub hnyav, cov khoom siv luam yeeb tsawg yog siv los txhim kho cable kev nyab xeeb, cov neeg haus luam yeeb, thiab nplaim taws thaum hluav taws.
Siv: lub ntsej muag sheath yuav tsum ua raws li GB / T 6995.2 cov qauv. Yog tias lub fiber ntau yog b1.3-hom, lub sheat yuav tsum daj; Rau B6-hom, lub sheat yuav tsum daj lossis ntsuab; Rau Aia.1-hom, nws yuav tsum yog txiv kab ntxwv; Hom-hom yuav tsum yog grey; A1A.2-hom yuav tsum yog Cyan ntsuab; thiab A1A.3-hom yuav tsum yog ntshav.
Daim Ntawv Thov Kev Pab Cuam
1. Cov chaw sib txuas lus hauv kev sib txuas lus hauv tsev, xws li ua haujlwm, tsev kawm ntawv, tsev kawm ntawv, tsev kawm ntawv, tsev kawm nyiaj, thiab lwm yam kev sib txuas lus nrog cov neeg ua haujlwm sab nraud. Ib qho ntxiv, sab hauv tsev kho qhov muag tau tuaj yeem siv tau hauv cov xov network hauv tsev, xws li LANS thiab cov tshuab ntse thiab ntse dua.
2. Kev siv: Cov xov tooj sab hauv yog kev cog lus kho qhov muag, qhov chaw-txuag, thiab yooj yim rau nruab thiab tswj hwm. Cov neeg siv tuaj yeem xaiv ntau hom kev kho kho kho kho qhov muag kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho kho qhov muag tshwj xeeb.
Hauv cov tsev ib txwm lossis chaw ua haujlwm, qauv sab hauv tsev PVC CABLE yuav siv tau.
Raws li tus qauv hauv tebchaws GB / T 51348-2019:
①. Cov vaj tse nyob nrog qhov siab ntawm 100m lossis ntau dua;
②. Cov vaj tse pej xeem nrog qhov siab ntawm 50m thiab 100m thiab thaj chaw tshaj 100,000㎡;
③. Cov ntaub ntawv chaw ntawm qib B lossis siab dua;
Cov no yuav tsum siv cov nplaim-retardant optical cables nrog hluav taws kub ntsuas tsis muaj qis dua li cov pa luam yeeb tsawg, halogen-dawb B1 qib.
Hauv UL1651 tus qauv hauv Asmeskas, cov nplaim taws ntau tshaj plaws-retardant Cable hom yog ofnp-rated offic-exting tsis pub dhau 5 meters thaum raug nplaim taws. Ib qho ntxiv, nws tsis tso pa luam yeeb los yog vapor, ua kom haum rau kev teeb tsa hauv cua khov kho lossis cua-rov qab lub tshuab hVAC.
