Niaj hnub no, cia kuv piav qhia txog cov qauv ntawm cov cables Ethernet marine. Hauv lwm lo lus, cov cables Ethernet txheem muaj cov hlau conductor, txheej rwb thaiv tsev, txheej tiv thaiv, thiab txheej sab nraud, thaum cov cables armored ntxiv txheej sab hauv thiab txheej tiv thaiv ntawm cov ntaub thaiv thiab txheej sab nraud. Nws yog qhov tseeb tias cov cables armored tsis yog tsuas yog muab kev tiv thaiv ntxiv xwb tab sis kuj tseem muaj txheej tiv thaiv sab hauv ntxiv. Tam sim no, cia peb tshuaj xyuas txhua yam khoom kom meej.
1. Tus Neeg Coj: Lub Hauv Paus ntawm Kev Xa Xov Tooj
Cov xov hlau Ethernet muaj ntau yam khoom siv xws li tooj liab tinned, tooj liab liab qab, hlau txhuas, tooj liab-clad txhuas, thiab tooj liab-clad hlau. Raws li IEC 61156-5: 2020, cov xov hlau Ethernet hauv dej hiav txwv yuav tsum siv cov xov hlau tooj liab khov kho uas muaj qhov loj ntawm 0.4 hli thiab 0.65 hli. Raws li qhov xav tau rau kev xa xov ceev dua thiab kev ruaj khov nce ntxiv, cov xov hlau qis dua xws li txhuas thiab tooj liab-clad txhuas tab tom raug tshem tawm, nrog tooj liab tinned thiab tooj liab liab qab tam sim no tswj hwm kev ua lag luam.
Piv rau tooj liab liab, tooj liab tinned muaj kev ruaj khov tshuaj zoo dua, tiv taus oxidation, tshuaj xeb, thiab av noo kom tswj tau kev ntseeg siab ntawm lub voj voog.
Cov xov hlau muaj ob hom: cov xov hlau khov kho thiab cov xov hlau hlua. Cov xov hlau khov kho siv ib txoj xov tooj liab xwb, thaum cov xov hlau hlua muaj ntau txoj xov tooj liab nyias nyias ntswj ua ke. Qhov sib txawv tseem ceeb yog kev ua tau zoo ntawm kev xa xov - vim tias thaj chaw hla loj dua txo qhov poob ntawm kev ntxig, cov xov hlau hlua qhia tau tias muaj kev txo qis siab dua 20% -50% dua li cov xov hlau khov kho. Qhov sib txawv ntawm cov xov hlau kuj ua rau DC tsis kam.
Feem ntau cov xov hlau Ethernet siv cov xov hlau 23AWG (0.57mm) lossis 24AWG (0.51mm). Txawm hais tias CAT5E feem ntau siv 24AWG, cov pawg siab dua xws li CAT6/6A/7/7A feem ntau xav tau 23AWG rau kev ua haujlwm zoo dua. Txawm li cas los xij, cov qauv IEC tsis yuam kom muaj cov xov hlau tshwj xeeb - cov xov hlau 24AWG uas tsim tau zoo tseem tuaj yeem ua tau raws li CAT6+ cov lus qhia.
2. Txheej rwb thaiv tsev: Tiv thaiv kev ncaj ncees ntawm lub teeb liab
Cov txheej rwb thaiv tsev tiv thaiv cov teeb liab xau thaum lub sijhawm xa xov. Ua raws li IEC 60092-360 thiab GB / T 50311-2016 cov qauv, cov xov hlau marine feem ntau sivpolyethylene siab ntom (HDPE)los yog ua npuas dejpolyethylene (PE Ua Npuas Ncauj). HDPE muaj kev tiv taus kub zoo heev, lub zog kho tshuab, thiab kev tiv taus kev tawg ntawm ib puag ncig, ua rau nws siv tau dav. Foamed PE muab cov khoom dielectric zoo dua, ua rau nws zoo tagnrho rau cov xov hlau CAT6A + ceev ceev.
3. Kev Sib Cais Hla: Txo Kev Sib Txuas Lus ntawm Cov Teeb Meem
Tus cais hla (tseem hu ua tus sau hla) yog tsim los cais plaub khub sib ntswg ua plaub fab sib txawv, txo qhov sib txuas ntawm cov khub. Feem ntau ua los ntawm cov khoom siv HDPE nrog lub cheeb ntawm 0.5 hli, qhov khoom no yog qhov tseem ceeb rau Pawg 6 thiab cov cables qib siab dua uas xa cov ntaub ntawv ntawm 1Gbps lossis sai dua, vim tias cov cables no qhia tau tias muaj kev cuam tshuam ntau dua rau lub suab nrov thiab xav tau kev tiv thaiv kev cuam tshuam zoo dua. Yog li ntawd, Pawg 6 thiab cov cables saum toj no uas tsis muaj ib khub ntawv ci tiv thaiv thoob ntiaj teb suav nrog cov ntawv sau hla los cais plaub khub sib ntswg.
Nyob rau hauv kev sib piv, Pawg 5e cables thiab cov uas siv cov qauv ntawv ci uas muaj khub-shielded tsis suav nrog qhov cross filler. Qhov kev teeb tsa twisted-pair ntawm Cat5e cables muab kev tiv thaiv kev cuam tshuam txaus rau lawv cov kev xav tau bandwidth tsawg dua, tshem tawm qhov xav tau kev sib cais ntxiv. Ib yam li ntawd, cov cables nrog cov ntawv ci-shielded khub siv cov ntawv ci txhuas lub peev xwm los thaiv cov kev cuam tshuam electromagnetic zaus siab, ua rau qhov cross filler tsis tsim nyog.
Lub zog tensile ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kom cov cable ntev uas yuav ua rau kev ua haujlwm tsis zoo. Cov tuam txhab tsim cable ua lag luam feem ntau siv cov fiberglass lossis nylon ua cov khoom siv tensile hauv lawv cov qauv cable. Cov ntaub ntawv no muab kev tiv thaiv zoo tshaj plaws thaum tswj cov yam ntxwv ntawm kev sib kis ntawm cable.
4. Txheej Tiv Thaiv: Kev Tiv Thaiv Hluav Taws Xob
Cov txheej tiv thaiv muaj cov ntawv ci txhuas thiab/lossis cov ntaub mesh braided los thaiv EMI. Cov xov hlau ib txheej tiv thaiv siv ib txheej ntawv ci txhuas (tuab ≥0.012mm nrog ≥20% sib tshooj) ntxiv rau txheej PET mylar los tiv thaiv cov hluav taws xob xau. Cov qauv tiv thaiv ob txheej muaj ob hom: SF/UTP (ntawv ci tag nrho + braid) thiab S/FTP (ntawv ci ib khub + braid tag nrho). Cov ntawv ci tooj liab tinned (hlau txoj kab uas hla ≥0.5mm) muab kev npog uas hloov kho tau (feem ntau 45%, 65%, lossis 80%). Raws li IEC 60092-350, cov xov hlau marine ib txheej tiv thaiv xav tau cov hlau ntws rau hauv av, thaum cov qauv tiv thaiv ob txheej siv cov ntawv ci rau kev tso tawm hluav taws xob.
5. Txheej Txheem Cuab Yeej: Kev Tiv Thaiv Tshuab
Cov txheej txheem tiv thaiv ua rau muaj kev tiv thaiv tensile/crush thiab txhim kho EMI shielding. Cov xov hlau marine feem ntau siv cov cuab yeej braided raws li ISO 7959-2, nrog rau cov hlau galvanized (GSWB) muab lub zog siab thiab tiv taus cua sov rau cov ntawv thov uas xav tau, thaum cov hlau tooj liab tinned (TCWB) muab kev ywj pheej zoo dua rau cov chaw nqaim.
6. Sab Nraud Sheath: Ib puag ncig Shield
Lub plhaub sab nraud yuav tsum du, sib npaug, thiab tshem tawm yam tsis ua rau cov khaubncaws sab hauv qab puas tsuaj. Cov qauv DNV xav tau qhov tuab (Dt) kom yog 0.04 × Df (txoj kab uas hla sab hauv) +0.5 hli, nrog rau qhov tsawg kawg nkaus 0.7 hli. Cov xov hlau hauv dej hiav txwv feem ntau sivLSZH (pa luam yeeb tsawg xoom-halogen)cov ntaub ntawv (SHF1/SHF2/SHF2 MUD qib ib IEC 60092-360) uas txo cov pa phem thaum muaj hluav taws.
