1.4 Ntsiab Lus

Ua ke cov khoom lag luam zoo thiab xhlpe rwb thaiv tsev, XHhw hlau ua kom muaj kev nyab xeeb thiab ruaj khov rau sab hauv / sab nraud, tshwj xeeb tshaj yog nyob rau hauvxhhw nyob hauv avthiabncaj qha fausCov dej num .

2. voltage ntsuam xyuas ntawmXhhwHlau piav qhia

2.1 Txheem Volfage Ntsuas

XHhw Hlau feem ntau yog ntsuas rau ob theem voltage tseem ceeb: 600 v) thiab 1 kilitolt (1 kl) {{} Kuv cov khoom siv ntau:

Ntsuam xyuas 600V:Feem ntau siv nyob rau hauv thaj chaw thiab teeb muaj cov tshuab hluav taws xob .

1000V ntsuam xyuas:Haum rau kev lag luam hnyav, lag luam vaj tse, thiab cov khoom siv hluav taws xob siab {}}

Cov kev ntsuas uas ua tau raws li North American NEC (National Electrical Code) Cov Qauv) Cov Qauv Txheej Txheem thiab Ulu (Underuring Kev Nyab Xeeb, kom ntseeg tau thiab ntseeg tau .

2.2 Qhov sib txawv ntawm XHHW thiab XHHW -2

Muaj ob hom ntawm XHHW Hlau:

Xhhw:Rated rau 90℃nyob rau hauv qhuav ib puag ncig thiab 75℃nyob rau hauv cov chaw ntub dej, nrog voltage kev ntsuas ntawm 600v lossis 1000v {}}

Xhhw -2:Ib qho kev hloov kho tshiab tsim rau 90℃nyob rau hauv ob qho chaw qhuav thiab ntub kev haum, thaum tswj hwm 600V thiab 1000v voltage ntaus {}}

Yog li, hauvXhhw Hlau Ncaj Nceeslossisxhhw nyob hauv avKev txhim kho, XHHHW -2 feem ntau pom zoo vim nws qhov kev hloov kho tshiab thiab ib puag ncig kev hloov kho.

2.3 Cov Qauv thiab Cov Ntawv Pov Thawj

Lub voltage ratings thiab kev ua tau zoo ntawm xhhw xaim yog tswj hwm los ntawm:

Nec code:Qhia cov kev siv thiab voltage txwv ntawm XHHW hlau, tshwj xeeb tshaj yog hais txog ntub thiab av applicions .

UL Ntawv Pov Thawj:Ua kom cov xov hlau sib ntsib peb cov qauv kev nyab xeeb, lav kev rwb thaiv tsev thiab cov tshuab ua kom muaj zog ntawm kev ntsuas hluav taws xob {}}

Cov qauv no kom paub tias txawm ntsia liXhhw hlau hauv conduitlossis faus rau hauv av, XHHW hlau ua haujlwm muaj kev nyab xeeb thiab ntseeg tau .

{{03. qhov tseem ceeb ntawm cov hluav taws xob ntsuas hluav taws xob hauv kev siv

3.1 Xaiv cov kev ntsuas hluav taws xob tsim nyog

Xaiv qhov ntsuas hluav taws xob raug rau XHHW hlau yog qhov tseem ceeb hauv cov khoom siv hluav taws xob kom tsis txhob muaj cov cuab yeej siv hluav taws xob, lossis phom sij:
