1. Nkag siab XHHW Hlau: Khoom Siv Tseem Ceeb
XHhw xo yog lub thickoset-insulated hluav taws xob cable tsim rau cov chaw xav tau. Nws rwb thaiv tsev muaj cov ntoo khaub lig-txuas nrog Polyethylene (XLPE), uas muab cov kev tshwj xeeb tsis kam, noo noo, thiab tshuaj lom neeg. Cov yam ntxwv tseem ceeb suav nrog:
Kub tiv thaiv: Rated txog 90 degree nyob rau hauv ntub dej ntub lossis qhuav cov xwm txheej, tshaj qhov kev ua tau zoo ntawm ntau cov qauv xov hlau.
Dej tiv: XLPE rwb thaiv tsev tiv thaiv kev nqus dej, ua rau nws zoo tagnrho rau cov ntawv thov qhuav lossis submerged.
Yam ruaj khov: Tiv thaiv kom puas tsuaj, roj, thiab tshav ntuj, ua kom muaj kev cia siab ntev hauv qhov chaw hnyav.
Cov yam ntxwv no ua rau XHHHW hlau ib qho kev sib tw ua kom muaj zog rau cov tub rog ib puag ncig, qhov chaw ua xeb thiab noo noo yog kev hem thawj.
2. Aluminium Xhhw -2 vs. Tooj liab XHHHW: Cov kev txiav txim siab
Aluminium Xhhw -2
Aluminium Xhhw {{0} xaim sib xyaw ua ke tus nqi-ua haujlwm zoo ntawm txhuas nrog lub rwb thaiv tsev ntawm XHHW. Cov ntsiab lus muaj xws li:
Lub teeb yuag: Aluminium qis qis qis txo qhov teeb tsa kev teeb tsa, zoo tagnrho rau cov nkoj marine uas qhov hnyav cuam tshuam roj ua haujlwm.
Corrosion Kuj: Thaum paired nrog XLPE rwb thaiv tsev, Txhuas Xhhw {{>> hais tias kev sib txuas ntawm kev sib txuas yog qhov tseem ceeb los tiv thaiv cov corrosion galvanic.
Tus Nqi Muaj Zog: Aluminium yog pheej yig dua tooj liab, muab cov nyiaj khaws cia rau cov phiaj xwm marrine loj.
Txawm li cas los xij, Aluminium yuav tsum tau tus neeg xyuas loj loj kom haum tooj liab lub peev xwm tam sim no, uas yuav txwv nws siv hauv cov ntawv thov chaw.
Tooj liab XHhw hlau
Tooj liab tseem yog tus qauv kub rau kev ua haujlwm thiab kev ntseeg tau. Tau txais txiaj ntsig hauv cov chaw ua haujlwm Marine muaj xws li:
Zoo tshaj ua haujlwm: Tooj liab tes ua kom tau xeb nrog cov gauge me me, ua kom zoo rau qhov chaw ntawm cov nkoj lossis cov pa hluav taws.
Oxidation tsis kam: Tsis zoo li aluminium, tooj liab dhau kev corrosion, txawm nyob rau hauv qab ntsev ib puag ncig, thaum insulated nrog xlpe.
Yooj yooj: Tooj liab tus neeg ua hauj lwm tsis yooj yim installation installifies installation installation instic marine compartartments.
Thaum tooj liab XHHW yog kim dua, nws lub siab ntev thiab ua tau zoo lav cov peev txheej hauv cov chaw ua haujlwm tseem ceeb marine.
3. XHhw Vs. Thhn: Vim li cas cov chaw ua haujlwm ua haujlwm ua haujlwm xhhw
Thahn (thermoplastic high kub-resistant nylon-coal) hlau tau dav siv nyob rau hauv kev lag luam thiab chaw nyob tab sis poob rau hauv cov chaw ua haujlwm marine piv piv rau XHHW:
Rwb thaiv tsev ntaub: Thhn siv thermoplastic rwb los txwv, uas cuam tshuam sai dua nyob rau hauv lub sij hawm UV raug thiab noo noo. XHhw lub thermoset xlpe khaws cia ncaj ncees hauv kev mob hnyav.
Kev Ntsuas Kub: Thhn tau ntsuas rau 90 degree hauv cov xwm txheej qhuav tab sis tsuas yog 75 degree thaum ntub dej. XHHW tswj hwm nws 90 kev ntsuam xyuas degree hauv ob qho chaw ntub thiab qhuav.
Tshuaj Kuj: XHHW Outperforms Thhn ntawm kev tawm tsam roj, acids, thiab cov kuab tshuaj uas pom hauv cov tub rog.
Rau cov ntawv thov marine, XHhw lub rwb thaiv tsev loj thiab dual-rated kub kom ua kom nws xaiv kev nyab xeeb dua.
4. Kev siv ntawm xhhw xaim hauv cov av marine
XHhw hlau lub versatility txhawb ntau hom txiv marine marine:
Nkoj Hluav Taws Xob Hluav Taws Xob: Fais fab faib khoom siv, teeb pom kev zoo, thiab tshuab navigation, thiab cov tshuab ua tau los ntawm xhhw noo noo tsis kam.
Offshore Zog Infrastrasure: Yaub Zog Hloov (Wecs) thiab tidal turbines, nthuav tawm rau corrosive seawater, cia siab rau cov ntaub qhwv tsis ntev zoo li XHHW kom txo qis.
Dock thiab Harbor Instidations: Submerged lossis txaws-Dag-Dag rau Piers, twj, thiab sensors thiab sensors xav tau xhhw cov dej muaj resistant.
Kev tshawb nrhiav cov tub rog cov tub rog txuas ntxiv dua tshiab, xws li cov siv A36 cov txheej txheem steel, ua qhov tseem ceeb ntawm cov ntaub ntawv-corrosion-resistant cov ntaub ntawv. Thaum cov kab ke no ntsuas cov qauv ntawm cov qauv, lawv cov xaim hluav taws xob zoo li XHHW kom tiv taus dej ntsev rau cov kua txiv.
5. Ua raws cai thiab cov qauv rau cov roj hmab-qib
XHhw xaim tau ntsib cov qauv kev lag luam tseem ceeb, txhawm rau kev nyab xeeb thiab sib xyaw:
UL 44 thiab UL UL 903: Daim ntawv pov thawj XHHW rau siv nyob rau hauv cov chaw ntub thiab qhov chaw kub-ib puag ncig.
Nec tsab xov xwm 310: Cim tau XHHW raws li tsim nyog rau ceg circuits thiab beeders hauv cov ntawv thov marine.
ISO 10133: Cov Qauv Txheej Txheem Thoob Ntiaj Teb rau Tsawg-Voltage Cov Khoom Pom Zoo XHhw-Hom Rwb Thaiv Tsev Rau DC Circuits.
Cov ntawv pov thawj no underscore XHHW txoj kev ntseeg tau rau kev ntseeg tau rau kev siv roj av, ua raws li qhov kev xav tau ntawm ntug dej.
6. Cov tswv yim sib tw thiab kev cog lus
Thaum XHHW EXCELS hauv chaw nres nkoj, kev teeb tsa kom zoo thiab kev txij nkawm yog qhov tseem ceeb:
Galvanic corrosion: Pairing Aluminium Xhhw -2 nrog cov hlau tsis sib xws (piv txwv li, stainless hlau) tuaj yeem nrawm corrosion. Siv cov khoom siv dielectric lossis kev rho tawm kom txo cov kev phom sij no.
Uv Kev Ruaj Ntseg: Txawm hais tias XHHW tiv tshav zoo dua li Thhn, kev tiv thaiv ntxiv ntxiv tau qhia rau kev ncua UV ntev.
Mechanical kev ntxhov siab: Kev ruaj ntseg hluavtaws nrog cov pob zeb-qib marine-hom kom tiv thaiv kev puas tsuaj los ntawm cov hlab ntsha deeg.
7. Yav Tom Ntej Tiam: Kev Tawm Tsam Hauv Marine Hlau
Kev nce qib hauv cov khoom kev tshawb fawb yog txhim kho XHHW cov tub rog lub cev:
Nano-coated neeg xyuas: Cov thev naus laus zis siv tshuaj tiv thaiv kev tiv thaiv kab mob nanocotings kom aluminium xhhhw -2}}}, txuas ntxiv txuas nws lifespan.
Hybrid Rwb Thaiv Tsev: Sib txuas nrog XLPE nrog Silicone txheej txhim kho hloov tau yooj yim thiab thermal ruaj khov rau huab cov tub rog huab tais.
Muaj zog: Siv lub rwb thaiv tsev XLPE rwb thaiv tsev ua ke nrog kev lag luam marine rau kev daws teeb meem hauv eco-phooj ywg.
