MassLink 1728-Prysmian High Fiber Count Cable
Prysmian pab pawg, tam sim no nrog rau cov Draka, muaj 1728 fiber ntau hauv cov kab xoob txoj siv kev lag luam. Lub cable yog muaj npe raws li MassLink 1728. Loose tube Ribbon kev siv ua ke cov cwj pwm zoo ntawm ob qho chaw xoob thiab cov ribbons. Prysmian nyiam hu nws Ribbon stranded tube cable. Lub lag luam cov khoom catalogs hais tias, 1728 fiber ntau cable ntau tshaj plaws suav suav muaj nrog lawv. Cov fais fab loj cov cab cab ciav hlau siv cov ciav hlau siv rau hauv kev lag luam tseem ceeb xws li kev sib kis ntawm tus choj.
Prysmian lub 1728 fiber ntau cable yog zoo tagnrho rau kev sib txuas loj cov roj ntsha loj sib txuas. Lub cable muaj kev tuav yoojyim li nws yog sib dua hauv qhov hnyav piv rau ntau tus naj npawb ntawm cov cables thaum tus installer siv qis fiber ntau cables. MassLink 1728 cable yog tsim los nrog cov pob ribbonized. Ob leeg 12 thiab 24 fiber ntau ribbons yooj yim rau huab hwm coj strip thaum installation. Ribbonized fibers kuj pub huab hwm coj fusion splicing. Ribbons tau yooj yim phom los ntawm 24 fiber ntau rau ob tug neeg 12 fiber ntau dua. Qhov no ua rau kev siv cov hluav taws xob fusion hauv kev siv lub tshuab fusion thaum lub sijhawm ntawd.
Pawg fusion splicing txuag ntau Ribbonized fibers kuj tseem yuav phua rau tus neeg lub cev kom sai thiab huv. Qhov no tso cai rau kev sib tw ntawm tus kheej daim fibers nrog uas ntawm kev sib txuas nrog cov hlua txuas nrog cov fibers. Ribbon pawg fusion splicing txuag nyiaj ntau heev thiab sij hawm rau tus tswv ntawm tus tswv tsev tus tswv.
MassLink 1728 hom cables yog muaj nyob rau hauv cov kabmob tua kabmob uas zoo li qub. Nas cov neeg tuaj yeem yog qhov zoo tshaj yog tau los ntawm kev thov ib txheej ntawm daim kab xev, feem ntau yog corrugated, uas yog tom qab lub npe hu ua ib armor mus rau cable los ntawm cov nas. Cov txheej txheem no ua rau kom cov kab txuas mus rau cov neeg kho kev ntxhov siab. Prysmian siv cov dej tsis zoo thaiv, uas tso cai ceev cov kab ua lag luam thiab txiav tawm raws li cov dej thaiv cov ntaub ntawv yuav raug muab tshem tawm yooj yim ntawm cov tub ntxhais cable. Ntau cov xoob ntes tsis tso cov hlua khi uas siv cov txheej txheem rov qab oscillation. MassLink 1728 cable yog qhov yoojyim rau txhua txoj hau kev los ua kom yooj yim nkag, tuav thiab tswj cov fibers thiab ribbons. Termination yog ua kom yooj yim dua nrog cov xov tooj ntawm cov ribbons hauv txhua lub raj ntim.
Lub cables yog tsim nyob rau hauv Prysmian qhov chaw nyob hauv US thiab Canada. Cable ua raws li RDUP (RUS) tau teev tseg raws li PE-90, 7CFR 1775.900. Cable tuaj yeem ua raws li qhov yuav tsum tau ua kom muaj li 20 lub sij hawm siv cov kab hluav taws xob thiab lub thooj ntim qis li ntawm 10 npaug ntawm cov kab hluav taws xob. Thaum lub caij txhim kho, txoj hlua yuav rub tau nrog lub siab tshaj plaws zog ntawm 4500N, uas sib npaug ntawm 1000 lbf. Tidile tensile zog, uas yog, tom qab kev txhim kho, cov qauv tsim tso cai rau 800N, uas yog sib npaug ntawm 180 lbf. Tsoo tiv thaiv 220N / cm (125 lbf / nti) tuaj yeem siv rau cable rau lub sij hawm luv luv, thaum lub sij hawm ntev zuaj tiv thaiv yuav tsum yog 110N / cm (63 lbf / nti). MassLink 1728 cable yuav muab nruab rau qhov kub li tsawg li -30 degree C. Cov ntsuas kub siab tshaj yuav tsum muaj +70 degree C. Lub cable cia ua haujlwm hauv ntau hom kub nrog yam tsawg kawg yog -40 deg C thiab siab tshaj plaws + 70 degree C. Yuav tsum muab pov tseg los yog xa dej thaum kub uas txawv ntawm -40 degree C mus rau +75 degree C.
MassLink 1728 cables muaj nyob hauv All-dielectric tsim thiab tsim ib qho Armor / tes-tsho tsim. 432 fibers yog muab tso rau hauv ib lub raj ntim hauv tshuab raj. Yog li, yuav muaj 4 leeg tsis tuaj. Lub raj ntim ntawm lub kaum hli yog nyob ib ncig ntawm 12.1 hli (millimeters), uas nyob ib ncig ntawm 0.476 nti. Tag nrho-dielectric cable muaj ib lub dav diameter ntawm 31.5 hli, thaum lub ris tsho tiv thaiv phab ntsa yog 35.1 hli. Armor cable yog hnyav dua All-dielectric cable. Qhov hnyav ntawm All-dielectric cable yog 749 kg / km, thaum lub qhov hnyav ntawm armor cable yog 965 kg / km. Tshaj siab tshaj plaws ntev yog 3.020 meters rau kev siv xov tooj cua All-dielectric, hos lub sij hawm ntev tshaj plaws ntawm armor cable yog 2,170 meters.
