Hauv cov tes hauj lwm sib txuas lus niaj hnub no, txawm tias nyob rau hauv kev teeb tsa sab nraum zoov lossis sab hauv tsev fiber optic cabling systems, kev ruaj khov mus sij hawm ntev ntawm cov optical cables nyob ntawm ntau yam khoom siv tseem ceeb - aramid yarn. Nrog nws cov khoom sib dua, lub zog tensile siab, thiab kev hloov pauv zoo heev rau ib puag ncig, aramid yarn yog siv dav hauv ADSS cables, FTTH fiber optic cables, sab hauv tsev optical cables, thiab ntau yam kev sib txuas lus optical cables, qhov twg nws ua haujlwm ua lub ntsiab tensile thiab cov qauv txhawb nqa, ua rau nws yog ib feem tseem ceeb ntawm cov khoom siv optical cable niaj hnub no.
1. Xov Paj Aramid: Cov Khoom Siv Txhawb Nqa Cable Muaj Zog Siab
Aramid fiber yog ib hom fiber polyamide uas muaj zog heev. Hauv kev lag luam cable optical, cov fiber aramid modulus siab feem ntau yog ua tiav rau hauv cov xov aramid, uas yog siv los txhim kho lub zog tensile thiab kev ruaj khov ntawm cov cable optical.
Piv nrog cov ntaub ntawv siv hlau ua kom muaj zog ib txwm muaj, cov xov aramid muaj ob qho tib si lub teeb thiab lub zog siab. Nws qhov ceev tsuas yog li ib feem tsib ntawm cov hlau hlau, thaum nws lub zog tshwj xeeb siab dua li cov hlau. Qhov no tso cai rau nws kom txo qhov hnyav ntawm cov xov hlau tag nrho thaum tseem muab kev txhawb nqa kho tshuab txhim khu kev qha, ua rau nws yog cov khoom siv txhawb nqa zoo tshaj plaws ntawm cov xov hlau kho qhov muag.
Tsis tas li ntawd,Cov xov aramidNws muaj cov modulus elastic siab thiab elongation qis, ua rau txo qis kev ntxhov siab ntawm cov khoom siv kho qhov muag. Qhov no pab txo qhov poob ntawm kev khoov me me thiab kev cuam tshuam ntawm lub teeb liab. Ua cov khoom siv kho qhov muag ua tau zoo, cov xov aramid kuj muaj kev ruaj khov zoo, tiv taus kev laus, tiv taus kev xeb tshuaj lom neeg, thiab cov khoom rwb thaiv tsev zoo heev. Nws tsis muaj cov khoom siv hlau thiab yog li ntawd tshem tawm qhov kev pheej hmoo ntawm kev xeb, ua rau nws tsim nyog rau kev siv mus sij hawm ntev hauv kev sib txuas lus kho qhov muag.
2. ADSS Cables: Aramid Yarn rau Long-Span Aerial Installations
Hauv kev sib txuas lus fais fab, ADSS (All-Dielectric Self-Supporting) optical cable yog ib qho ntawm cov ntawv thov tseem ceeb tshaj plaws ntawm aramid yarn. Txij li thaum ADSS cables raug ntsia raws cov kab hluav taws xob siab dhau ntawm qhov ntev, lawv xav tau cov ntaub ntawv txhawb nqa cable ua haujlwm siab nrog lub zog tensile zoo heev thiab cov khoom rwb thaiv tsev.
Hauv cov qauv cable ADSS, cov xov aramid muaj zog siab feem ntau yog siv ua lub hauv paus tseem ceeb los tiv taus cua, qhov hnyav ntawm tus kheej, thiab kev nruj ntawm lub zog. Piv nrog cov qauv txhawb nqa hlau, cov xov aramid sib dua thiab tsis tsim cov hluav taws xob, ua rau nws tsim nyog dua rau cov chaw muaj hluav taws xob siab.
Los ntawm kev kho cov qauv thiab cov ntsiab lus ntawm cov xov aramid, ADSS cables tuaj yeem tsim rau ntau qhov sib txawv thiab cov kev xav tau ntawm lub zog kho tshuab. Yog li ntawd, lawv tau siv dav hauv thaj chaw roob, hla dej, thiab cov kab ke sib txuas lus hluav taws xob ntev.
3. Cov Cables Optical Sab Hauv Tsev: Txhim Kho Kev Ywj Pheej thiab Kev Ruaj Ntseg ntawm Kev Teeb Tsa
Piv nrog rau ADSS cables, cov cables kho qhov muag sab hauv tsev tsom mus rau qhov yooj ywm thiab kev tiv thaiv khoov. Hauv cov chaw xws li cov chaw khaws ntaub ntawv, FTTH networks, thiab cov kab ke cabling, cov cables feem ntau raug khoov thiab teeb tsa conduit ntau zaus, ua rau muaj kev xav tau ntau dua rau cov ntaub ntawv txhawb nqa cable.
Cov xov hluav taws xob sab hauv tsev ib txwm muaj, xws li GJPFJV cables, siv cov qauv ntawm "tight-buffered fiber + aramid yarn reinforcement layer + outer sheath". Hauv cov qauv no, aramid yarn yog siv los nqus cov zog tensile thiab kev ntxhov siab sab nraud, tiv thaiv cov fiber ntau thiab txhim kho kev ruaj khov ntawm kev xaus.
Vim nws qhov kev ywj pheej zoo heev thiab kev ua haujlwm zoo, cov xov aramid txo qhov kev puas tsuaj los ntawm kev khoov thaum lub sijhawm teeb tsa thiab kev ua haujlwm, ua kom muaj kev ruaj khov ntev ntawm cov xov hluav taws xob sab hauv tsev. Yog li ntawd, nws tau dhau los ua cov khoom siv tseem ceeb hauv cov kab ke hluav taws xob sab hauv tsev niaj hnub.
Xaus lus
Ua ib qho khoom siv tseem ceeb rau kev txhawb nqa cov xov hluav taws xob optical cable, cov xov aramid yog siv dav hauv ADSS cables, cov xov hluav taws xob sab hauv tsev, FTTH cables, thiab ntau yam kev sib txuas lus optical cable systems. Nrog nws cov qauv sib dua, lub zog tensile siab, kev tiv thaiv ib puag ncig zoo heev, thiab kev ua haujlwm ruaj khov, cov xov aramid ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ntseeg tau ntawm cable thiab kev ua haujlwm ruaj khov mus sij hawm ntev. Rau cov chaw tsim khoom siv optical cable, kev xaiv cov xov aramid zoo yog qhov yuav tsum tau ua kom ntseeg tau tias cable ua haujlwm tau zoo thiab lub neej ua haujlwm.
