Cov khoom siv hluav taws xob muaj kev ruaj ntseg rau lwm cov khoom siv hluav taws xob, xws li lub thawv tawg-pov thawj, cov khoom siv hluav taws xob, thiab cov ntsaws ruaj ruaj, ntawm cov qog hluav taws xob tawg, uas yog cov khoom siv hluav taws xob nkag mus rau qhov kawg ntawm cov cables. Nyob rau hauv ib qho nyuaj los yog txaus ntshai qhov chaw uas yuav tsum tau sealing thiab ingress tiv thaiv, lawv yog ib qho tseem ceeb heev rau txiav xov hlau. Lawv kuj tseem muab cov kev daws teeb meem zoo thiab tiv thaiv cov xaim hluav taws xob me me los ntawm xeb, dej, cov pa phem, corrosion, thiab corrosion.
Raws li koj tuaj yeem pom, ib puag ncig uas cov qog no ua haujlwm yuav tsum sib phim. Lub caj pas cable yuav tsum tau ua kom ntev dua nyob rau hauv qhov chaw nyuaj vim tias siv lub caj pas tsis raug yuav kim. Tsis tas li ntawd, lawv yuav tsum raug xaiv raws li cov txheej txheem siv los tiv thaiv kev tawg. Yog li, cov lus nug tseem ceeb yog: koj yuav ua li cas xaiv qhov tsim nyog tawg-pov thawj cable caj pas? Txhawm rau kom paub tseeb tias siv cov kab hluav taws xob zoo, ntau cov txheej txheem yuav tsum tau coj mus rau hauv tus account. Kawm ntxiv los ntawm kev nyeem rau.
Kev xav txog cov kab mob qog noj ntshav
Xav txog cov hauv qab no ua ntej xaiv koj cov kab mob tawg-pov thawj zoo meej:
Puas yuav siv lub caj pas rau sab hauv lossis sab nraud?
Dab tsi yog qhov kev nyab xeeb ntawm cheeb tsam kev faib tawm qhov twg lub caj pas txuas txuas?
Lub caj pas puas yuav muab tso rau hauv thaj chaw uas muaj plua plav lossis ntub dej?
Puas muaj cov tshuaj corrosive lossis gases hauv cheeb tsam?
Puas yog lub caj pas cable tsim nyog rau kev siv cable qhov loj thiab hom?
Koj qhov kev xaiv ntawm cov qog qog yuav nyob ntawm seb koj teb cov lus nug no li cas. Raws li cov ntsiab lus no, kev tiv thaiv plating lossis txheej txheej ntawm cov qog yuav txawv.
Ntau hom kab mob qog noj ntshav
Txhawm rau pab koj txiav txim siab seb cov kab hluav taws xob twg yog qhov zoo tshaj plaws rau koj qhov project, cia peb mus dhau qee yam ntawm cov kab mob tawg-pov thawj thiab lawv cov kev siv:
Rau kev siv sab hauv tsev thiab kev teeb tsa me me, siv ib qho compression.
Cov kab hluav taws xob no muaj ob daim ntawv thov compression ntawm cov tub ntxhais cable thiab nyob rau sab nrauv sheathing lossis armour, nrog rau ob-compression sealing. Lawv yog li tsim nyog rau kev lag luam thiab cov chaw tsim hluav taws xob uas xav tau kev sib khi ruaj khov.
Hose uas hloov tau yog tsim nyog rau ib puag ncig uas muaj qhov kub thiab txias dua.
Steel-wire armored (SWA) cables, kev lag luam tus qauv rau phab ntsa cabling thiab subterranean installation, yog siv nrog armored cable caj pas.
Waterproof - IP68 waterproofing yog muab los ntawm waterproof cable glands, uas muaj peev xwm tiv taus submersion nyob rau hauv dej uas yog tsawg kawg yog ib meter tob.
Cov khoom zoo corrosion thiab siab resistant yog stainless hlau.
Flexible, xeb-pov thawj, thiab ua kom sov thiab hluav taws xob zoo yog aluminium.
Muaj zog thiab resistant rau deformation ntawm ob qho tib si kub thiab tsis kub, tooj dag muab lub zog. Nws muaj zog hluav taws xob conductivity thiab.
Thaum koj tau txiav txim siab hom kev tawg-pov thawj cable caj pas los ua haujlwm, koj yuav tsum tau coj mus rau hauv tus account lub caj pas cov lus qhia kom paub tseeb tias cov cable yuav haum los ntawm nws. Cov ntsiab lus tseem ceeb uas yuav tsum nco ntsoov yog raws li hauv qab no:
Hlau qhov txoj kab uas hla: Cov hlau qhov taub yuav tsum loj txaus kom haum rau tag nrho cov kab ke.
Tus nqi ntawm lub siab nws tuaj yeem txhawb nqa yam tsis muaj qhov xau yog qhia los ntawm kev ntsuas siab.
Cable txoj kab uas hla - Lub cable yuav tsum muaj ib txoj kab uas hla uas loj txaus noj los ntawm lub caj pas cable.
Txoj kab uas hla uas tuaj yeem hloov pauv kom haum rau cov kab sib txawv ntawm cov kab sib txawv yog lub npe hu ua txoj kab uas hla ntawm lub caj pas.
Qhov txoj kab uas hla ntawm lub barrier los yog bulkhead qhov nyob rau hauv uas lub cable caj pas yog mounted yog hu ua lub mounting qhov taub.
Kev siv hluav taws xob tawg-pov thawj cable
Cov kab mob tawg-pov thawj yog tsim raws li ATEX Cov Lus Qhia 2014/34/EU, uas hais txog cov cuab yeej thiab kev ntsuas kev nyab xeeb txhais tau tias siv rau hauv qhov chaw muaj peev xwm tawg. Lawv tau tsim tshwj xeeb rau kev siv hauv cov xwm txheej corrosive / phom sij. Cov dej hiav txwv, roj, thiab roj yog qee qhov piv txwv. Lawv feem ntau siv nyob rau hauv gearbox systems rau nruab nrab thiab high voltages.
Raws li koj tuaj yeem pom, muaj ntau yam yuav tsum coj mus rau hauv tus account thaum xaiv qhov tawg-pov thawj cable caj pas rau koj lub tuam txhab.
