OPGW (Optical Ground Wire) yog ib hom kab hluav taws xob siv hauv kev lag luam kev sib txuas lus kom xa cov ntaub ntawv los ntawm fiber ntau optic technology, thaum tseem muab hluav taws xob xa hluav taws xob nyob rau hauv high voltage overhead fais fab kab.OPGW cables yog tsim los nrog lub hauv paus raj lossis cov tub ntxhais, nyob ib puag ncig uas tau tso ib lossis ntau txheej ntawm cov hlau los yog txhuas hlau, thiab txheej txheej ntawm optical fibers.Kev tsim kho ntawm OPGW cables txawv nyob ntawm daim ntawv thov thiab cov kev cai tshwj xeeb ntawm cov kab hluav taws xob.
Muaj peb yam yooj yim ntawm OPGW cable qauv:
Central Tube: Hom kab no muaj cov raj hauv nruab nrab, nyob ib puag ncig uas tau tso cov hlau xaim lossis txhuas hlau xaim.Tom qab ntawd cov fibers optical muab tso rau hauv lub raj.Qhov kev tsim no tso cai rau kom yooj yim dua thiab muab qhov chaw ntau dua rau cov fibers optical.
Txheej Stranding: Hom kab no muaj ob peb txheej ntawm cov hlau los yog txhuas hlau uas tau tso tseg ua ke.Cov fibers optical yog nteg nyob rau hauv interstices ntawm cov xov hlau.Cov qauv tsim no muab lub zog ntau dua thiab tsim nyog rau kev siv siab nruj.
Unitube: Hom kab no muaj ib lub raj uas ob lub hlau los yog txhuas hlau thiab cov fibers optical tau nteg.Qhov no tsim muab ib tug compact cable uas yooj yim rau nruab.
OPGW cables kuj tseem tuaj yeem raug cais raws li lawv cov fiber ntau suav, uas nyob ntawm 12 txog 288 fibers.Kev xaiv ntawm fiber ntau yog nyob ntawm daim ntawv thov tshwj xeeb thiab lub peev xwm ntawm cov kab hluav taws xob.
