1.Dab tsi yog FRP Fiber Optic Cable?
FRPkuj tuaj yeem xa mus rau fiber ntau reinforcement polymer siv nyob rau hauv fiber optic cables. Fiber optic cables yog tsim los ntawm iav los yog yas fibers uas xa cov ntaub ntawv siv lub teeb teeb liab. Txhawm rau tiv thaiv cov fibers tsis yooj yim thiab muab cov khoom siv dag zog, lawv feem ntau ntxiv dag zog nrog cov tswv cuab hauv nruab nrab ua los ntawm fiber ntau reinforcement polymer (FRP) lossis hlau.
2. Yuav ua li cas txog FRP?
FRP stands rau Fiber Reinforced Polymer, thiab nws yog ib hom ntawm cov khoom sib xyaw uas feem ntau siv hauv fiber ntau optic cables ua cov tswv cuab muaj zog. FRP muab txhua yam kev txhawb nqa rau cable, uas pab tiv thaiv kev puas tsuaj rau cov fiber ntau optic strands hauv cov kab. FRP yog ib qho khoom zoo nkauj rau fiber ntau optic cable vim nws muaj zog, hnav, thiab tiv taus corrosion thiab lwm yam ib puag ncig. Nws kuj tseem tuaj yeem ua tau yooj yim molded rau hauv cov duab sib txawv thiab qhov ntau thiab tsawg, ua rau nws hloov tau mus rau ntau hom kab tsim.
3.Qhov zoo ntawm Kev Siv FRP hauv Fiber Optic Cables
FRP (Fiber Reinforced Polymer) muaj ntau yam zoo rau kev siv fiber ntau cable.
3.1 Lub zog
FRP muaj qhov sib txheeb ze li ntawm 1.5 txog 2.0, uas tsuas yog ib lub hlis twg rau ib feem tsib ntawm cov pa roj carbon steel. Txawm li cas los xij, nws lub zog tensile yog piv rau lossis txawm siab dua li ntawm cov hlau. Tsis tas li ntawd, nws lub zog tshwj xeeb tuaj yeem piv rau cov qib high-qib alloy steel. FRP muaj lub zog siab thiab nruj, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau cov tswv cuab cable. Nws tuaj yeem muab kev txhawb nqa tsim nyog los tiv thaiv cov kab hluav taws xob fiber ntau los ntawm sab nraud quab yuam thiab tiv thaiv kev puas tsuaj.
3.2 Lub teeb
FRP yog qhov sib dua li cov hlau lossis lwm yam hlau, uas tuaj yeem txo qhov hnyav ntawm fiber ntau cable. Piv txwv li, ib tug raug steel cable hnyav 0.3-0.4 phaus ib ko taw, thaum sib npaug FRP cable hnyav xwb 0.1-0.2 phaus ib ko taw. Qhov no ua rau nws yooj yim dua los tuav, thauj, thiab teeb tsa lub cable, tshwj xeeb tshaj yog nyob rau hauv huab cua lossis tshem tawm daim ntawv thov.
3.3 Corrosion-resistant
FRP tiv taus corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav, xws li marine lossis underground daim ntaub ntawv. Nws tuaj yeem pab tiv thaiv cov fiber ntau cable los ntawm kev puas tsuaj thiab txuas ntxiv nws txoj sia. Nyob rau hauv ib txoj kev tshawb fawb luam tawm nyob rau hauv Phau ntawv Journal of Composites rau Kev Tsim Kho, FRP cov qauv raug rau qhov hnyav marine ib puag ncig pom tau tias muaj kev puas tsuaj tsawg heev tom qab 20 xyoo raug.
3.4 Tsis-conductive
FRP yog ib yam khoom uas tsis yog-conductive, uas txhais tau hais tias nws muaj peev xwm muab hluav taws xob rwb thaiv tsev rau lub fiber cable. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas cuam tshuam hluav taws xob tuaj yeem cuam tshuam kev ua haujlwm ntawm fiber ntau cable.
3.5 Tsim Flexibility
FRP tuaj yeem raug molded rau hauv cov duab sib txawv thiab qhov ntau thiab tsawg, uas tuaj yeem tso cai rau ntau tus qauv tsim thiab kev teeb tsa cable. Qhov no tuaj yeem pab txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm fiber ntau cable.
