1. Nkag siab XHHW thiab Xhhw -2 xaim xaub
Txhais thiab Kev Tsim Kho
Xhhw sawv rauNtoo khaub lig-txuas Polyethylene (XLPE) Muaj Kub Kub-resistant thiab dej-resistant hlauCov. Nws yog lub thickoset-insulated cable tsimD rau kev ua kom ntev hauv kev xav tau ib puag ncig. Qhov "Xhhw -2" ntau yam "sib txawv, muab cov kev ntsuas kub ua kom qhuav (905 degree hauv cov chaw ntub dej) 5. Ob hom kev sivHla-Txuas Polyethylene (XLPE)Rwb thaiv tsev, uas muab kev tiv thaiv zoo dua, noo noo, thiab muaj piv rau cov ntaub ntawv thermopastic zoo li PVC.
Cov Ntsiab Lus Tseem Ceeb
Kev Ntsuas Hluav Taws Xob: 600 volts (txuj ci).
Qhov ntsuas kub ntau:
Xhhw: txog li 90 degree hauv cov chaw qhuav, 75 degree hauv cov chaw ntub dej.
Xhhw -2: 90 degree hauv ob qho chaw qhuav thiab ntub dej.
Cov Khoom Siv Ua: Feem ntau cov txhuas (aa {{-8000 series) lossis tooj liab, nrog stranding optimized rau kev hloov kho tau.
Rwb Thaiv Tsev Thickness: Sib txawv los ntawm tus thawj coj loj (piv txwv li, 45-65 me mils rau AWG loj dua).
2. Voltage ntsuas ntsuas ntsuas thiab ua raws
Cov Qauv Kev Lag Luam
Qhov ntsuas ntsuas ntawm XHHW hlau yog tswj hwm los ntawm ntau tus qauv:
UL 44: Qhia txog cov tseev kom muaj rau cov thermoset-insulated xov hlau, suav nrog xhhw -2.
NEC (National Electrical Code): Piav qhia cov lus qhia teeb tsa, xws li NEC 310.104 rau cov ntawv thov kev coj ua.
ASTM B801 / B836: Npog cov qauv coj tus coj tus neeg no.
RoHS Ua Raws: Ua kom muaj kev nyab xeeb ib puag ncig los ntawm kev txwv cov tshuaj muaj kev phom sij.
Cov sawv cev sawv cev (u 0 / u)
Cable coltage kev ntsuas feem ntau yog qhia raws liU0/U, qhov twg:
U0: Cov voltage ntsuas ntawm tus neeg saib xyuas thiab av (piv txwv li, 600v).
U: Cov hluav taws xob ntsuas ntawm cov neeg saib xyuas (piv txwv li, 1, 000 v).
Piv txwv li, cim cim ntawm "6kv / 1kv" qhia tau cov hlau yog haum rau 600V theem-rau-hauv av thiab 1kv theem-rau-theem tshuab.
Qhov kev ntsuas no ob zaug ua kom tau raws li cov phiaj xwm voltibility nrog daim phiaj voltage fluctues thiab carient surges surges.
3. Yam cuam tshuam ntau voltage muaj peev xwm
Rwb thaiv tsev ntaub
XLPE rwb thaiv tsev hauv xhhw -2 muaj:
Siab dua dielectric lub zog piv rau PVC.
Kuj mus rau thermal degradation, txawm nyob ntawm 90 degree.
Cov pa luam yeeb qis thaum lub sijhawm ua ke, txhim kho kev nyab xeeb.
Ib puag ncig ib puag ncig
Ya raws tsis kam: Xhhw -2 'ristant rwb thaiv tsev tso cai rau siv nyob rau hauv damp los yog nyob hauv av.
Qho so: Kev khiav hauj lwm kub dua (piv txwv li, 90 degree) tej zaum me ntsis txo cov hluav taws xob tiv thaiv ntev dua vim yog rwb thaiv tsev laus.
Tus neeg xyuas pib loj thiab stranding
Cov neeg hloov kho loj (piv txwv li, 4 / 0 awg) muaj rwb thaiv tsev tuab los tswj kev ncaj ncees. Kris-Tech cov specifications qhia pom rwb thaiv tsev tuab xws li ntawm 30 mils (rau 14 awg) mus rau 65 mils (rau 500 mcm).
4. Piv nrog thhn / thwn xaim
Thaum Xhhw -2 thiab thhn / thwn qhia txog 600V ntsuam xyuas, qhov tseem ceeb sib txawv muaj xws li:
| Chaw ua uas tsis tau haus | Xhhw -2 / XLPE | Thhn / thwn |
|---|---|---|
| Kev rwb thaiv tsev | Hla-Txuas Polyethylene | PVC Nrog Nylon Tsho |
| Max kub | 90 degree (ntub dej / qhuav) | 90 degree (thwn), 75 degree (thhn) |
| Yooj yooj | Tswj kav | Siab dua vim nylon |
| Tus nqi | Siab dua | Qi dua |
| Kev Nyab Xeeb Kev Nyab Xeeb | Tsawg haus luam yeeb emission | Nplaim taws-retardant pvc |
Xhhw -2} yog nyiam rau ib puag ncig muaj kev ntxhov siab (piv txwv li, thaum Thoj / thwn hnav cov phiaj xwm raug nqi.
5. Cov ntawv thov ntawm Xhhw -2 xaim hlau
Kev Siv Ntau
Lub Zog Fais Fab: Kev pabcuam enlances, feeders, thiab ceg nruab nrab.
Kev Muaj Hluav Taws Xob: Tshuab, tswj vaj huam sib luag, thiab conveyor tshuab.
Sab nraum zoov: Conduits, av thoob plaws hauv av, thiab cov chaw ntub dej.
Kev Kawm Txog Kev Kawm: Nexans Eurio T-Pob Tsuas
Nexans 'XHHHW -2 Cable yog qhov ntsuas rau 600V thiab 90 degree, ua rau lawv zoo tagnrho rau cov tsev siab thiab noo chaw ib puag ncig. Lawv asa -8000} aluminium txhuas coj ua kom tau raws li ASTM cov qauv rau kev hloov kho kom yooj thiab.
6. Volgage kev ruaj ntseg liab
NEC Cov Lus Qhia pom zoo ua haujlwm cables ntawmTsawg dua los yog sib npaug rau 75% ntawm rated voltagenyob rau hauv ib txwm muaj mob. Surges kev sib tham ib ntus (piv txwv li, 120% ntawm kev ntsuam xyuas) yog kev tso cai tab sis yuav tsum tsis pub tshaj 1 teev8. Rau ib qho 600v xhhw -2 xaim:
Kev Siv Nruam: Tsawg dua los yog sib npaug rau 450V.
Lub sijhawm luv-kawm: Tsawg dua los yog sib npaug rau 720V.
7. Ntiaj teb cov qauv thiab hloov txawv
North America: Xhhw -2} Ua raws li UP thiab NEC cov qauv.
Yu Laus teb: Cov zaub mov zoo ib yam (piv txwv li, RW90) yuav siv qhov kev ntsuas 1KV hauv qab IEC cov qauv.
Axias: Cov tuam ntxhab zoo li Nexans Adv tsim qauv rau cov phiaj xwm hauv zos (piv txwv li, 12-20kV system).
8. Yav Tom Ntej
Ntau dua cov kev ntsuas ntau dua: Cov qauv XLPE uas tshwm sim tuaj yeem ua kom 1kv + kev ntsuas rau xhhw -2.
Muaj zog: Kev siv ntau dua siv cov khoom siv ua dua tshiab los ntsib cov qauv ROHS thiab mus txog cov qauv.
