1. FRP Fiber Optic Cable yog dab tsi?
FRPKuj tseem tuaj yeem xa mus rau cov polymer fiber reinforcement siv hauv cov cables fiber optic. Cov cables fiber optic yog ua los ntawm cov iav lossis yas fibers uas xa cov ntaub ntawv siv cov teeb liab. Txhawm rau tiv thaiv cov fibers tawg yooj yim thiab muab lub zog kho tshuab, lawv feem ntau raug txhawb nqa nrog lub hauv paus muaj zog ua los ntawm cov polymer fiber reinforcement (FRP) lossis hlau.
2. Ua li cas txog FRP?
FRP sawv cev rau Fiber Reinforced Polymer, thiab nws yog ib hom khoom sib xyaw uas feem ntau siv rau hauv cov cables fiber optic ua ib qho khoom siv muaj zog. Lub FRP muab kev txhawb nqa rau lub cable, uas pab tiv thaiv kev puas tsuaj rau cov xov fiber optic hauv lub cable. FRP yog ib yam khoom zoo rau fiber optic cable vim nws muaj zog, tsis hnyav, thiab tiv taus corrosion thiab lwm yam ib puag ncig. Nws kuj tuaj yeem yooj yim pwm rau hauv ntau yam duab thiab qhov ntau thiab tsawg, ua rau nws hloov tau rau ntau yam qauv cable.
3. Cov txiaj ntsig ntawm kev siv FRP hauv Fiber Optic Cables
FRP (Fiber Reinforced Polymer) muaj ntau yam zoo rau cov ntawv thov fiber cable.
3.1 Lub zog
FRP muaj qhov ceev sib piv ntawm 1.5 txog 2.0, uas tsuas yog ib feem plaub txog ib feem tsib ntawm cov hlau carbon.
