Electronic Cable- Composite Overhead Ground Wire Nrog Optical Fibers (OPGW) Wasin Fujikura
kev taw qhia
► OPGW lossis lub npe hu ua Optical Ground Wire yog ib hom kab hluav taws xob nrog cov khoom sib txuas ntawm cov khoom siv kho qhov muag thiab cov khoom siv hluav taws xob hauv av rau kev xa hluav taws xob. Nws yog siv rau hauv cov kab hluav taws xob sib txuas ob qho tib si li optical fiber cable thiab nyiaj siv ua haujlwm hauv av xaim uas tuaj yeem muab kev tiv thaiv ntawm xob laim tawm tsam thiab ua rau luv luv tam sim no.
► OPGW muaj stainless hlau raj optical chav tsev, txhuas cladding hlau hlau, txhuas hlau hlau. Nws muaj central stainless hlau raj qauv thiab txheej stranding qauv. Peb tuaj yeem tsim cov qauv raws li qhov sib txawv ib puag ncig thiab cov neeg siv khoom xav tau.
Feature
► Stainless-steel optical fiber unit ntawm central xoob raj los yog txheej stranding qauv
► Aluminium alloy hlau thiab txhuas clad steel hlau armored
► Coated nrog anticorrosive roj ntawm txheej
► OPGW tuaj yeem txhawb nqa hnyav thiab kev teeb tsa ntev
► OPGW tuaj yeem ua tau raws li hauv av xaim qhov yuav tsum tau muaj ntawm cov tshuab thiab hluav taws xob los ntawm kev kho cov feem ntawm cov hlau thiab txhuas.
► Yooj yim los tsim cov lus qhia zoo sib xws ntawm cov xaim hauv av tuaj yeem hloov cov xaim hauv av uas twb muaj lawm.
► OPGW muab cov tuam txhab fais fab siv sijhawm los siv lawv cov yees rau lwm lub hom phiaj dua li kev xa hluav taws xob. Lawv rau kev nqis peev me me tuaj yeem muab Kev Tshaj Lij Siab Tshaj Lij rau Telecom sector.
Cov khoom siv
► OPGW cable yog khiav, los yog ntsia nruab nrab ntawm cov high-voltage hluav taws xob pylons, steel, ntoo, los yog qhob ncej nrog tsim nyog fittings thiab attachments. Lub conductive ib feem ntawm cable, nyob rau hauv cov ntaub ntawv no cov hlau ua hauj lwm nyob rau hauv daim ntawv cog lus nyob ib sab yees rau hauv av, thiab shields high-voltage conductors los ntawm xob laim ntaus.
► OPGW muaj tus yam ntxwv uas tsis muaj qhov cuam tshuam ntawm qhov hluav taws xob siab induction ntawm cov ntaub ntawv raug xa mus los ntawm Fibers. Li no tus yam ntxwv ntawm Fiber yog coj mus rau hauv kom zoo dua mus rau kis cov ntaub ntawv raws lub siab zog kis kab.
► Optical fibers nyob rau hauv lub cable yuav siv tau rau high-ceev kis tau tus mob ntawm cov ntaub ntawv. Cov khoom siv hluav taws xob tuaj yeem siv cov fiber ntau optics rau nws qhov SCADA, kev tiv thaiv thiab tswj cov kab sib txuas, VOIP, thiab lwm yam kev sib txuas lus. Hauv cov xwm txheej zoo li no, lawv tuaj yeem txuag tau tus nqi ntawm kev txhim kho cov hlau txuas ntxiv ua haujlwm hauv av lossis thaiv cov xov hlau rau lawv cov kab. Lawv kuj tuaj yeem xauj lossis muag rau cov neeg thib peb los ua kev sib txuas lus ceev fiber ntau ntawm cov nroog, thiab lwm lub network.
