OPGW yog ob txoj haujlwm ua haujlwm ntawm cable ua lub luag haujlwm ntawm cov xaim hauv av thiab tseem muab thaj chaw rau kev sib kis ntawm lub suab, video lossis cov ntaub ntawv teeb liab.Cov fibers muaj kev tiv thaiv los ntawm ib puag ncig tej yam kev mob (xws li xob laim, luv luv Circuit Court, thauj khoom) kom ntseeg tau tias muaj kev ntseeg siab thiab siv tau ntev.Lub cable yog tsim los nruab rau ntawm cov kab sib txuas thiab xaim xaim xaim kom nqa lub suab, cov ntaub ntawv thiab kev sib txuas lus video, tshwj xeeb tshaj yog nyob rau hauv lub teeb pom kev zoo waveform saib xyuas qhov system, ib qho kev soj ntsuam rau cov khoom siv hluav taws xob, kev saib xyuas cov ntaub ntawv xov xwm, cov kab hluav taws xob tiv thaiv kab mob, cov kab hluav taws xob ua haujlwm. , thiab unmanned substation xyuas.
GL tsom rau FO cable txoj kev loj hlob thiab kev tsim khoom rau 16 xyoo thiab OPGW yog ib qho ntawm peb cov khoom tseem ceeb, Peb cov khoom raug xa tawm mus rau ntau tshaj 160 lub teb chaws.Muaj 4 qhov kev txiav txim siab ntawm OPGW fiber ntau optic cables muab los ntawm GL.
OPGW Hom Tsim ntawm Central Stainless Steel Loose Tube, Lub hauv paus stainless hlau raj yog ib puag ncig los ntawm ib los yog ob txheej txheej ntawm txhuas clad steel hlau (ACS) los yog sib tov ACS xov hlau thiab txhuas hlau hlau.yog cov cables siv dav tshaj plaws, lawv cov qauv tsim tau hloov kho kom haum rau cov kab hluav taws xob feem ntau xav tau.
OPGW Hom Kev Tsim Qauv ntawm Stranded Stainless Steel Tube, Stranded Optical Ground Wire (OPGW) yog tso tseg los ntawm ob lossis peb txheej ntawm aluminium clad steel hlau (ACS) los yog sib xyaw ACS xov hlau thiab txhuas hlau hlau, Nws tsim tau ua kom haum rau feem ntau. hluav taws xob kab xav tau.
AL-them Stainless Hlau Tube OPGW, Lub hauv paus AL-them steel raj yog ib puag ncig los ntawm ib lossis ob txheej ntawm aluminium clad steel hlau (ACS) los yog sib xyaw ACS xov hlau thiab txhuas hlau hlau. ntawm AL, kom ncav cuag qhov kev txhaum tam sim no zoo dua thiab kev ua haujlwm ntawm xob laim.Ua rau cov kab sib kis uas yuav tsum muaj txoj kab uas hla me me thiab qhov txhaum loj tam sim no.
PBT Aluminium Tube OPGW, PBT Loose Tube Optical Ground Wire (OPGW) yog ib puag ncig los ntawm ib qho lossis ob txheej txheej ntawm aluminium clad steel hlau (ACS) lossis sib tov ACS xov hlau thiab txhuas hlau hlau.Kev ua haujlwm zoo los tiv thaiv corrosion.Cov khoom siv thiab cov qauv zoo ib yam, zoo tiv thaiv kev co qaug zog.
