Submarine cable ua si ib lub luag haujlwm tseem ceeb hauv kev sib tham hauv ntiaj teb, nqa cov ntaub ntawv ntau ntawm cov dej hiav txwv. Xaiv cov ntaub ntawv zoo rau cov cables yog qhov tseem ceeb los xyuas kom lawv lub siab, thiab ntseeg tau hauv cov chaw nyob hauv qab dej nyuaj. Hauv tsab xov xwm no, peb yuav tshawb txog cov kev cov nyom nrog kev xaiv cov ntaub ntawv rau kev daws teeb meem thiab sib tham txog cov kev daws teeb meem uas tuaj yeem pab txiav txim siab.
Corrosion Kuj:
Ib qho ntawm thawj cov nyom hauv submarine cab tsim yog corrosion. Cov qoob loo muaj tshwm sim rau dej hiav txwv, uas tuaj yeem ua rau muaj kev puas tsuaj loj ua rau lub sijhawm. Xaiv cov ntaub ntawv nrog cov khoom lag luam corrosion zoo tshaj yog qhov tseem ceeb rau lub neej ntev. Cov kev daws teeb meem xws li siv cov kev siv corrosion-resistant alloys nyiam stainless hlau lossis siv cov txheej txheem tshwj xeeb tuaj yeem muab kev tiv thaiv zoo tiv thaiv corrosion.
Neeg kho tshuab zog:
Submarine cabres yuav tsum tau kom muaj kev tiv thaiv lub siab thiab kev ntxhov siab ntau ntxiv vim yog dej hiav txwv kom dej hiav txwv, thiab cov dej nyhav. Xaiv cov ntaub ntawv rau submarine cables nrog kev kub siab txhua yam yog qhov tseem ceeb los xyuas kom cov cables tuaj yeem tiv thaiv cov rog no yam tsis muaj kev ncaj ncees. Cov ntaub ntawv muaj zog zoo li aramid fibers thiab carbon fiber ntau-polymers (CFRP) yog siv los txhim kho cov khoom siv ntawm submarine cable.
Dej thaiv thiab rwb thaiv tsev:
Tswj cov rwb thaiv tsev kom zoo thiab cov khoom thaiv dej-thaiv yog qhov tseem ceeb los tiv thaiv cov dej tso dej thiab tiv thaiv cov cable sab hauv. Polyethylene, polypropylene, thiab tus ntoo khaub lig-polyethylene (xlpe) feem ntau siv rau rwb thaiv tsev thiab dej-thaiv txheej hauv submarine cable. Cov ntaub ntawv no muaj cov khoom hluav taws xob zoo nkauj hluav taws xob thiab tuaj yeem tiv thaiv kev nkag mus rau hauv dej, ua kom muaj txiaj ntsig zoo tshaj plaws ntawm cov cable kev ua tau zoo thiab thiav.
Yooj thiab khoov radius:
Submarine cov cab kuj feem ntau yuav tsum tau hloov pauv tau thiab muaj peev xwm ntawm nrog cov khoom uas tsis muaj kev cuam tshuam lawv qhov kev ua tau zoo. Cov ntaub ntawv rau submarine cables nrog siab dua thiab qis dua li muaj qee yam kev sib cav sib ceg thaum tswj hwm cov hluav taws xob thiab cov tshuab hluav taws xob.
Thermal Stability:
Submarine CABLE yuav muaj kev kub ntxhov loj hauv ib puag ncig hauv qab dej. Nws yog qhov tseem ceeb los xaiv cov ntaub ntawv rau cov ntaub ntawv submarine nrog cov hluav taws xob zoo heev kom ntseeg tau cov khoom kub no yam tsis cuam tshuam lawv qhov kev ua tau zoo. Thermoplastic cov ntaub ntawv xws li polyethylene muaj kev xaiv zoo nrog rau kev rwb thaiv tsev thiab sheathing khaubncaws sab nraud.
Xaus:
Xaiv cov ntaub ntawv zoo rau cov txheej txheem submarine yog ib txheej txheem tseem ceeb uas cuam tshuam rau kev sib tw cov kev sib tw rau ib puag ncig hauv qab dej. Los ntawm kev daws cov ntsiab lus xws li corrosion tsis kam, kev thaiv lub zog, muab cov dej khov, cable tuaj yeem ua kom paub meej thiab muaj peev xwm ntawm submarine cable. Nkag siab cov kev cov nyom no thiab siv cov khoom siv uas tsim nyog yog qhov tseem ceeb rau kev sib txuas lus thiab kev sib txuas lus thoob ntiaj teb.
