1. Kev faib tawm ntawm lub nkoj ua haujlwm thiab cov ntsiab lus tseem ceeb rau kev xaiv Cable
Kev ua haujlwm ntawm cov nkoj feem ntau tau faib ua plaub hom: kev ua haujlwm tsis tu ncua, kev ua haujlwm berthing, tshwj xeeb ib puag ncig (siab kub / qis kub / corrosion), thiab lub xeev xwm txheej ceev.
Kev xaiv ntawm cable hom yuav tsum yog raws li cov yam ntxwv ntawm cov kev khiav hauj lwm tej yam kev mob kom phim cov cable kev ua tau zoo.
Cov xwm txheej tsis tu ncua
Nws raug nquahu kom xaiv cov hlua khi nkoj uas muaj nplaim taws- rov qab, qis- pa taws, halogen- dawb, thiab roj- tiv taus.
Tus neeg xyuas pib hla- ntu ntu yuav tsum ua kom tau raws li qhov ntev - lub sijhawm ntsuas tam sim no, thiab txheej txheej rwb thaiv tsev yuav tsum muaj cov khoom siv zoo thiab kev laus ua haujlwm.
Nws raug nquahu kom siv CJSC hom cables lossis cov qauv sib npaug.
Berthing Operation Conditions
Kev txav mus los tsis tu ncua thiab lub vojvoog me me yuav tsum tau siv cov xov tooj tshwj xeeb uas muaj qhov hloov tau yooj yim, tiv thaiv torsion, thiab hnav tsis kam, xws li towing cables lossis reel cables.
Cov ntaub qhwv yuav tsum muaj UV tiv taus thiab huab cua tsis kam.
Tshwj xeeb tej yam kev mob
Siab -Tseem Ceeb
Rau thaj chaw ze ntawm chav cav thiab boilers, xaiv qhov siab -cov kab hluav taws xob tiv taus kub (105℃thiab siab dua). Cov ntaub ntawv rwb thaiv tsev xws li ntoo khaub lig- txuas polyethylene lossis silicone roj hmab tau pom zoo.
Tsawg-Tsuas Kub
Rau cov tub yees txias thiab qhov chaw ncig teb chaws polar navigation, xaiv txias- cov kab hluav taws xob tiv taus nrog cov ntaub qhwv uas muaj peev xwm tswj tau qhov yooj yim ntawm -40℃.
Corrosive Ib puag ncig
Rau thaj chaw dej hiav txwv thiab tshuaj lom neeg, xaiv corrosion-cov ntaub ntawv tiv taus xws li polyurethane lossis neoprene, thiab siv cov hlau braided armor thaum tsim nyog.
Cov xwm txheej kub ntxhov
Rau cov tshuab tseem ceeb xws li kev tua hluav taws thiab teeb pom kev xwm txheej ceev, hluav taws kub- tiv taus, qis- pa taws, xoom-halogen, thiab qis- cov kab mob toxicity yuav tsum raug xaiv los ua kom muaj hluav taws xob tsis tu ncua thaum muaj hluav taws kub.
2. Technical Specifications rau Kev Muag Khoom ntawm Waterproof Marine Cables
Waterproof Qib Requirements
Kev ua haujlwm tsis zoo ntawm lub nkoj nkoj yuav tsum tsawg kawg ua tau raws li IP67 tus qauv (immersion hauv 1 meter dej rau 30 feeb yam tsis muaj dej nkag).
Rau thaj chaw tseem ceeb xws li hauv qab txoj kab dej, IP68 lossis siab dua yog pom zoo.
Thib peb-cov ntaub ntawv tshuaj xyuas tog neeg yuav tsum tau tshuaj xyuas thaum lub sijhawm yuav khoom.
Conductor Material Xaiv
Oxygen- cov khoom siv tooj liab dawb yog nyiam, nrog cov conductivity tsis qis dua 98% thiab cross-sectional deviation tswj nyob rau hauv ± 5%.
Rau siab - tam sim no circuits, tinned tooj liab conductors raug pom zoo los txhim kho oxidation kuj.
Rwb thaiv tsev thiab cov ntaub ntawv sheath

- Hla -txuas polyethylene (XLPE)
- Ethylene propylene roj hmab (EPR)
- Dielectric zog Ntau dua los yog sib npaug rau 20kV / mm
Sab hauv
- Nplaim-PVC retardant
- Tsawg- haus luam yeeb zero-halogen polyolefin
- Oxygen index> 32
Txheej txheej
- Roj-resistant polyurethane
- Hnav-resistant neoprene
- UV- cov ntaub ntawv tiv taus
Kev Tshawb Fawb Txog Cov Qauv Txheej Txheem
Tus Txheej Txheem Stranding
Tsis tu ncua stranding yuav tsum ua raws li tus qauv pitch diameter ratio yuav tsum tau.
Kev Tiv Thaiv Txheej Txheej
Cov kab hluav taws xob tseem ceeb yuav tsum siv tooj liab hlau braiding lossis txhuas-cov ntaub ntawv yas sib xyaw nrog cov kev pab them nqi siab tshaj 85%.
Tiv thaiv Armor
Galvanized steel hlau lossis steel daim kab xev armor yuav tsum tau siv nyob rau hauv cov cheeb tsam uas muaj kev puas tsuaj rau cov neeg kho tshuab siab.
3. Cov ntsiab lus tseem ceeb hauv Kev Ua Haujlwm Kev Ua Haujlwm
Technical Document Review
Cov neeg muag khoom yuav tsum muab:
- Hom ntawv xeem
- Daim ntawv pov thawj khoom pov thawj
- Cov ntawv pov thawj hauv zej zog xws li CCS, DNV, ABS, thiab lwm yam.
- Cov ntaub ntawv soj ntsuam cov ntaub ntawv raw
Kev tsom xam yuav tsum yog rau kev txheeb xyuas:
- Tus neeg xyuas pib kuj
- Rwb thaiv tsev tsis kam
- Voltage tiv thaiv cov ntaub ntawv xeem
Kev kuaj xyuas
Tom qab tuaj txog, cov qauv yuav tsum tau random tshuaj xyuas los ntawm batch.
Cov khoom kuaj muaj xws li:
- Conductor DC tsis kam
- rwb thaiv tsev thickness
- Sab nraud txoj kab uas hla
- Kev ntsuas hluav taws xob tiv thaiv (3.5kV / 5min)
- Flammability test (npuas kev ntsuas kub)
Yog tias tsim nyog, cov qauv yuav tsum raug xa mus rau thib peb -chaw kuaj xyuas thib peb rau rov- tshuaj xyuas.
Kev txheeb xyuas thiab Traceability
Cov kab hluav taws xob yuav tsum muaj cov ntaub ntawv txheeb xyuas tas li, suav nrog:
- Cable qauv
- Specification
- Txuj

- Meter marking
Kev ntim khoom yuav tsum ua kom tiav kom tsis txhob muaj kev puas tsuaj rau kev thauj mus los, thiab cov ntaub ntawv batch yuav tsum tsim kom muaj kev taug qab.
Ntawm -Tsev Neeg Kev Ntsuas Xyuas Qhov Chaw
Xyuas seb:
- Cable dabtsi yog khoov vojvoog raws li qhov yuav tsum tau ua
- Kev sib txuas davhlau ya nyob twg crimping zoo yog tsim nyog
- Waterproof connector sealing yog txhim khu kev qha
Tom qab kev teeb tsa, kev ntsuas hluav taws xob tiv thaiv thiab qhov ntsuas hluav taws xob tiv thaiv yuav tsum tau ua.
4. Kev xav tsis meej thiab ceev faj
Zam qhov "Low-Price Bidding" Trap
Marine cables ncaj qha ntsig txog kev nyab xeeb ntawm nkoj, yog li kev txiav txim siab yuav khoom yuav tsum tsis txhob cia siab rau tus nqi nkaus xwb.
Kev ua tau zoo, cov ntawv pov thawj tsim nyog, cov chaw tsim khoom lub koob npe nrov, thiab kev hloov pauv ib puag ncig yuav tsum tau soj ntsuam tag nrho.
Tsis txhob Environmental Misjudgment
Cov cheeb tsam hiav txwv sib txawv xws li thaj chaw kub thiab cov polar muaj cov kev cai sib txawv rau cov huab cua tiv thaiv kab mob thiab kev ua haujlwm ib puag ncig.
Kev xaiv cable yuav tsum sib phim rau thaj chaw navigation tiag tiag.
Tsis txhob hnov qab tso cov xwm txheej
Thaum muaj ntau lub cables tau muab tso rau hauv qhov sib npaug, qhov tam sim no - nqa cov khoom kho yuav tsum raug txiav txim siab kom tsis txhob muaj cua sov.
Tshawb xyuas Certification Scope
Paub meej tias cov ntawv pov thawj hauv zej zog suav nrog cov qauv cable tiag tiag thiab cov khoom tshwj xeeb uas tau yuav.
Qee cov tuam txhab lag luam tsuas yog muaj ntawv pov thawj rau ib feem ntawm cov khoom lag luam.
Xaus
Kev xaiv ntawm shipboard cables yuav tsum muaj kev soj ntsuam ntawm kev ua haujlwm thiab kev xav tau ib puag ncig.
Thaum lub sij hawm kev yuav khoom, kev tswj nruj yuav tsum tau tswj xyuas:
- Cov qauv txheej txheem
- Daim ntawv pov thawj kev tsim nyog
- Cov txheej txheem tshuaj xyuas zoo
kom muaj kev nyab xeeb thiab txhim khu kev qha cable ua haujlwm thoob plaws lub nkoj lub neej kev pabcuam.
Nws raug nquahu kom tsim kom muaj kev ntsuam xyuas tus neeg muag khoom thiab ua qhov tseem ceeb ntawm kev koom tes nrog cov tuam txhab lag luam uas muaj cov ntawv pov thawj hauv zej zog thiab ua tiav cov kev tswj hwm zoo.
