1. To taub XHHW Hlau: Muaj pes tsawg leeg thiab cov txiaj ntsig tseem ceeb
XHhw xaim yog ib hom qauv hluav taws xob insulated nrog tus kab mob sib txuas (XLPE), cov khoom siv uas muaj kuab lom, noo noo tsis txaus ntseeg, thiab tshuaj lom neeg inertness, thiab tshuaj lom neeg inertness. Cov khoom no ua rau nws zoo tagnrho rau cov chaw ua haujlwm hnyav, suav nrog cov pas dej da dej, qhov twg yog cov tshuaj ua luam dej, chlorine, thiab cov kev hloov pauv thiab cov kev hloov pauv ntau yog tshwm sim. Ntawm no yog kev sib tawg ntawm nws qhov tseem ceeb:
a. Zoo tshaj noo thiab tshuaj tua kab
Cov pas dej ua luam dej yog inherently ntub dej ib puag ncig, thiab cov tshuab hluav taws yuav tsum tau tiv thaiv ntev thiab cov tshuaj tua kab thiab cov tshuaj corrosive xws li chlorine. XHHW lub rwb thaiv tsev XLPE muab cov nyom ruaj khov rau cov dej ingress thiab tshuaj lom neeg ua haujlwm, tiv thaiv luv luv ci thiab rwb thaiv tsev.
b. Kub-Kub Ua Kom Tau
XHhw xaim yog qhov ntsuas rau qhov kub txog 90 degree (194 degree F) nyob rau hauv cov xwm txheej ntub thiab 150 degree (302 degree (302 degree (302 degree (302 degree (302 degree (302 degree (302 degree f) nyob rau hauv qhuav mob. Qhov no ua kom pom tseeb kev ua tau zoo txawm tias thaum nruab hnub tso cua sov, twj, lossis sab nraum zoov teeb pom kev zoo uas tsim kom muaj cua sov.
c. Yooj thiab ruaj khov
Txawm tias nws rugged rwb thaiv tsev, XHhw xaim tseem yoog raws, yooj yim installation hauv cov chaw kaw ntom nti ncig pas dej. Nws tsis tawm tsam tshem tawm thiab lub cev kev ntxhov siab txo txoj kev pheej hmoo ntawm kev puas tsuaj thaum lossis tom qab teeb tsa.
d. Ua raws li cov qauv kev nyab xeeb
XHhw xaim sib ntsib NEC (National Electrical Code) yuav tsum muaj rau cov chaw ntub thiab qhuav, ua rau kev teeb tsa chaw ua luam dej, hauv qab cov tshuab thiab cov twj tso kua mis.
2. Xhhw hlau hauv cov khoom ua luam dej
Cov pas dej da dej yuav tsum tau ua cov xaim tshwj xeeb rau kev teeb pom kev zoo, twj, cua sov, thiab tswj cov tshuab. Cia peb tshawb nrhiav li cas xhhw hlau sib ntsib cov kev xav tau no:
a. Underwater Teeb Pom Kev
Tsawg-voltage thiab kab-voltage pas dej teeb yuav tsum tau xaim uas tuaj yeem ua tiav subipersion thiab tshuaj lom neeg raug. XHHW lub rwb thaiv tsev dej tsis tu ncua kom muaj kev cia siab ntev, txawm tias thaum faus ze cov dej.
b. Twj tso kua mis thiab lub cev muaj zog circuits
Pas dej pas dej thiab cov motors kos cov xov xwm tseem ceeb tam sim no, kev siv xov hlau uas muaj ampacity siab. Cov khoom lag luam zoo li1aj 2awg XhhwMuab cov peev txheej tam sim no thaum tiv thaiv cua sov tsim.
c. Ncaj Nraim Cov Kev Raug Cai
Ntau lub pas dej sib xyaw ua ke yuav tsum tau xaim mus faus rau hauv av rau kev ua kom zoo nkauj thiab kev nyab xeeb.Xhhw Ncaj NceesTshem tawm qhov kev xav tau rau kev conduit hauv ntau kis, txo lub sijhawm thiab cov nuj nqis. Nws XLPE rwb thaiv tsev tiv thaiv cov av noo noo, lub hauv paus nkag mus, thiab av hauv av.
3. Tseem Ceeb XHHW cov khoom lag luam tshwj xeeb rau kev teeb tsa hauv tsev
Txhawm rau ua kom muaj kev ua luam dej ntau ntxiv rau cov haujlwm pas dej, cov neeg ua haujlwm feem ntau tsuas yog nyob ntawm kev teeb tsa xhhw. Hauv qab no yog cov khoom lag luam tseem ceeb ntawm cov khoom lag luam thiab lawv cov ntawv thov:
a. 1 / 0 xhhw 1000hw 1000V: High-voltage hla tshuab
Daim ntawv thov: Cov khoom lag luam loj loj lossis cov chaw uas xav tau cov khoom xa tawm high-voltage faib.
Qhov Zoo: Tus 1 {{0 00 v rating txhawb cov khoom siv hnyav, thaum lub 1/0 tsis loj uas muaj ampacity thiab yooj. Qhov zoo tagnrho rau cov ntsiab lus tseem ceeb lossis subpanels nyob ze pas dej.
b. 1aj 2awg XhhW: Kev Ntsuas Lub Hwj Chim thiab Yooj Yim
Daim ntawv thov: Nruab nrab pas dej ua ke, cua sov, thiab theem nrab voj voog.
Qhov Zoo: Cov gauges kov xob laim tam sim no thauj khoom thaum seem tau yooj yim los ntawm conduits lossis trenches.
c. 3 / {0 xhhw tooj liab 600V: Cov ntawv thov hnyav
Daim ntawv thov: Cov chaw nyob loj lossis cov pas dej ua lag luam nrog cov kev xav tau zoo.
Qhov Zoo: 3 / {0 Awg Tus Thawj Coj Nus siv hluav taws xob poob qis dua ntev, thiab 600V kev ntsuas haum feem ntau cov khoom siv cov pas dej. Tooj liab ua kom tau ua kom zoo dua li kev ua haujlwm zoo dua thiab corrosion tsis kam.
4. XHhw Ncaj Nraim faus: Yooj Yim Pas Wiring Yooj Yim
Ib ntawm xhhw lub standout nta yog nwsncaj qha fausmuaj peev xwm, uas ua kom yooj yim pas dej sib sau. Ntawm no yog vim li cas qhov teeb meem no:
Tus Nqi Muaj Zog: Tshem tawm cov ntawv qhia txo cov nqi thiab cov nqi ua haujlwm.
Lub Sij Hawm Txuag Nyiaj: Cov neeg cog lus tuaj yeem tso cov hlau ncaj qha hauv cov trenches, nrawm dua cov sijhawm ua haujlwm.
Yam ruaj khov: XLPE rwb thaiv tsev tiv thaiv cov av acidity, noo noo, thiab lub cev puas los ntawm kev hloov av.
Piv txwv li, burying3 / 0 xhhw tooj liab 600vHlau los txuas lub pas dej subpanel ua kom lub zog txhim khu kev qha tsis muaj cov hassle of PVC conduits.
5. Lub rooj sib tham nec thiab kev nyab xeeb qauv
Lub NEC (tsab xov xwm 680) Qhia cov lus qhia nruj nruj rau kev ua luam dej da cov xaim hluav taws xob kom tiv thaiv hluav taws xob thiab khoom siv tsis ua haujlwm. Xhhw hlau txiav nrog cov qauv no los ntawm:
Kev muab GFCI (Av ua txhaum Circuit Interrupter) sib xyaw rau cov hluav taws xob ze rau dej.
Kom ntseeg tau tias rwb thaiv tsev rwb thaiv tsev rau cov chaw ntub dej ntub dej / Damp.
Txhawb kev cog grounding los ntawm nws cov kev tsim kho ruaj khov.
6. Sib piv XHHW rau lwm tus (Thwn / Thwn, UF-B)
Thaum thahn / Thwn thiab UF-B cov xov xwm nyob rau sab nraum zoov tej yaam num, XHHW Outperforms lawv hauv pas dej teeb:
Thhn / thwn: Yuav tsum muaj Conduit rau kev faus thiab tsis muaj XHHW lub tshav kub tiv thaiv.
UF-b: Haum rau kev faus neeg ncaj tab sis muaj cov kev ntsuas kub tsawg thiab ampacity.
7. Txhim kho cov kev coj ua zoo tshaj plaws rau xhhw hauv pas dej
Txhawm rau kom ntseeg tau tias kev ua tau zoo tshaj plaws:
Kev siv1 / 0 xhhw 1000hw 1000rau high-voltage pub.
Tiv thaiv cov av saum toj saud nrog UV-resistant conduit.
Ua raws li cov lej hauv zos rau qhov tob ntawm qhov tob (feem ntau 18-24 nti).
