1.Thiab Xhhw hlau: Cov ntsiab lus tseem ceeb thiab cov txiaj ntsig
XHHW (Cross-txuas Polyethylene siab kub thiab dej-resistant) hlau muaj koob meej rau nws cov kev tsim kho kom zoo thiab kev hloov kho kom haum rau ib puag ncig. Hauv qab no, peb tawg cia nws cov ntsiab lus tseem ceeb thiab vim li cas nws outperforms ntau txoj kev xaiv.
1.1 XHhw Cov Hlau Specifications
Rwb thaiv tsev ntaub: Hla nrog polyethylene (xlpe) rwb thaiv tsev ua kom muaj cua sov, noo, tshuaj lom neeg, thiab puas.
Kev Ntsuas Hluav Taws Xob: Txheem xhhw hlau yog ntsuas rau li600V, thaumXhhw -2 AWG Cablethiab2 AWG Xhhw tooj liab 1000VCov variants yog haum rau cov ntawv thov ntau dua.
Qhov ntsuas kub ntau: Ua haujlwm tau zoo nyob rau hauv qhov kub ntawm -40 degree rau 90 degree ({} degree f rau 194 degree f).
Cov Xaiv Coj Xaiv: Muaj nyob rau hauv tooj liab (zoo dua li kev ua haujlwm) thiab txhuas (lub teeb yuag thiab raug nqi-tsim nyog), xws li2/9 {1}}} xhhw txhuas hlau.
Kev ceev kev cai: Ntsib UV 44, NEC piv txwv 310, thiab ASTM B3 / B8 qauv.
1.2 Vim li cas thiaj xaiv XHhw hlau?
Yam ruaj khov: XLPE rwb thaiv tsev tiv thaiv kev tawg, hnub ci (UV rays), thiab roj / roj teeb.
Yooj yooj: Yooj yim dua los lis tshaj li cov hlau sib tw hlau-clad cables.
Tus Nqi Muaj Zog: Aluminium txawv li2/9 {1}}} xhhw txhuas hlauTxo cov khoom siv tsis muaj kev cuam tshuam kev ua yeeb yam.
Kev xyuas xim: Nplaim taws-retardant thiab cov pa ncho pa hluav taws xob tsawg tsawg txo qhov phom sij.
2.PRRRR-Installation npaj rau XHHW Hlau
Kev teeb tsa tau zoo pib nrog kev nthuav dav tsis zoo. Ntawm no yog yuav npaj li cas rau txoj haujlwm ua tiav:
2.1 Ntsuam xyuas cov khoom hluav taws xob
Xam cov kev xav tau ntawm koj lub system los xaiv cov hlau raug. Piv txwv li:
2 AWG Xhhw tooj liab 1000Vsiv sijhawm txog 130A ntawm 75 degree.
2/9 {1}}} xhhw txhuas hlauTxhawb Nqa ~ 135A, Qhov zoo tshaj plaws rau cov kab kev noj haus.
Xa mus rau NEC ampacity cov rooj kom tsis txhob muaj nyob rau hauv- lossis oversizing.
2.2 Xaiv txoj cai XHHHW variant
Kev thov 600v: Tus qauvXHhw Hlau 600VSuffices rau cov chaw nyob ntau thiab lub teeb lag luam lag luam lag luam voj voog.
High-voltage xav tau: Xaiv rauXhhw -2 AWG Cablelossis2 AWG Xhhw tooj liab 1000VRau kev lag luam tshuab lossis hnub ci arrays.
Kev Siv Nyiaj Txiag: Aluminium counetors (piv txwv li,2/9 {1}}} xhhw txhuas hlau) Muab cov nyiaj txuag tseem ceeb rau cov haujlwm loj.
2.3 sib sau cov cuab yeej thiab cov ntaub ntawv
Cov cuab yeej hlau hlau, cov cuab yeej tawv nqaij, cov ntoo conduit, thiab voltage kuaj.
Conduit (PVC lossis hlau) rau kev tiv thaiv hauv thaj chaw lossis thaj chaw muaj kev puas tsuaj.
3.Qhov-los-qib qhia kev teeb tsa kev teeb tsa rau XHHW hlau
Kauj ruam 1: Npaj cov kev ua haujlwm
Siv cov conduit rau pvc conduit rau corrosive ib puag ncig lossis hlau conduit rau kev tiv thaiv kev tiv thaiv.
Nco ntsoov khoov ua raws li Nec Radius tseev kom muaj (piv txwv, 6x conduit ntawm inch rau EMS).
Kauj ruam 2: Ntsuas thiab txiav cov xaim
Qhov tseem ceeb hauv qhov ntev ntxiv (10-15%) rau kev txiav tawm thiab yav tom ntej hloov kho.
RauXhhw -2 AWG Cable, siv cov cutter teb kom tsis txhob muaj kev puas tsuaj rwb thaiv tsev.
Kauj ruam 3: Cov Sawb thiab TowinS Ciav
Sawb rwb thaiv tsev uas siv cov thermal stripper kom tiv thaiv tsis pub nicking tooj liab tooj / txhuas strands.
Siv tshuaj tiv thaiv oxidant rau2/9 {1}}} xhhw txhuas hlaukev sib txuas los tiv thaiv corrosion.
Kauj Ruam 4: Tso cai rau cov hlau hauv Conduit
Zam kev ua haujlwm ntawm cov khoom siv ntawm kev khaws cov khoom siv uas muaj haujlwm ntau dua lossis sib npaug 40% sau muaj peev xwm ib cov lus qhia.
Siv Cable Ties lossis Straps txhua 4-6 taw kom txhawb nqa.
Kauj Ruam 5: Kev Xeem Ntxiv thiab Rwb thaiv tsev
Use a megohmmeter to verify insulation resistance (>1, {000 egohms rau xlpe).
Ua ib qho hluav taws xob poob mus kuaj kom ntseeg tau tias muaj txiaj ntsig zoo.
4.Common yuam kev kom tsis txhob
Tsis quav ntsej siv kub ntsuas: Tshaj li 90 degree tuaj yeem ua rau rwb thaiv tsev.
NWS COPPER THIAB ALUMINIUM: Siv cov twj paj uas tau siv rau cov khoom siv.
Kev tsis txaus hauv av: Ib txwm nyiaj hlau hlau conduits thiab khoom siv.
5. Luam tawm ntawm XHHW Hlau
Muaj Panels: Xhhw -2 AWG Cabletxawj nyob rau hauv high-tshav kub manufacturing.
Hnub ci Farms: 2 AWG Xhhw tooj liab 1000Vwithstands sab nraum zoov UV kis tau.
Lub tsev lag luam: 2/9 {1}}} xhhw txhuas hlautxo cov nqi hauv cov neeg pub mis loj khiav.
