Puas yog XHHW HLAU RATE rau cov chaw ntub dej?

1. Nkag siab XHHW thiab XHHHW -2 hires

XHHW (Cross-txuas Polyethylene siab kub-resistant dej-resistant) hlau yog ib hom hluav taws xob cable tsim rau kev siv hluav taws xob ib puag ncig. Nws rwb thaiv tsev muajHla-Txuas Polyethylene (XLPE), cov khoom siv uas paub nws zoo heev thermal ruaj khov, puas tsis kam, thiab noo noo tsis kam.

TusXhhw -2 xaim hlauyog ib qho kev hloov kho ntawm XHHW, muab cov kev ua tau zoo hauv huab. Ob qho tib si cables yog ntsuas rau600VCov ntawv thov, tab sis lawv cov kev haum rau cov chaw ntub nyob ntawm cov ntawv pov thawj thiab cov qauv tsim kho.

2. Cov kev ntsuas chaw ntub: XHHW vs. Xhhw -2

Xhhw xaim nyob rau hauv qhov chaw ntub

Txheem XHHW Hlau yogtsis yog thoob ntiaj teb rau cov chaw ntub dejCov. Raws li UL 44 cov qauv, XHHW yog kev pom zoo tshwj xeeb rauqhuav thiab damp ib puag ncig, nrog rau tus neeg coj ua siab tshaj plaws ntawm 90 degree hauv cov xwm txheej qhuav. Txawm li cas los xij, nws noo noo-resistant xlpe rwb thaiv tsev tso cai rau nws ua hauvCov chaw qhuav(piv txwv li, nyob sab hauv tsev nrog cov av noo qee zaus).

Xhhw -2 xaim: Cov tshuaj ntub kev daws teeb meem

Hauv kev sib piv,Xhhw -2 xaim hlauyog qhia meej rauNtub thiab cov chaw qhuavCov. Nws rwb thaiv tsev thiab Jacketing cov ntaub ntawv hla kev sib txuas ntxiv, ua rau nws tiv thaiv lub sijhawm ntub dej, av noo thiab cov kev hloov pauv. Cov ntsiab lus tseem ceeb muaj xws li:

Kev Ua Si Kub Kub: Rated rau 90 degree hauv ob qho chaw ntub thiab qhuav.

Tshav ntuj thiab noo noo tsis kam: UV-Deg Stidilized XLPE rwb thaiv tsev tiv thaiv kev ua kom tsis txhob muaj kev mob siab rau sab nraum zoov lossis hauv av.

Ua raws li UL 44 thiab NEC: Pom zoo rau Conduit, Kev faus ncaj qha, thiab cov ntawv thov Raceway ib zaug rau cov xov tooj hluav taws xob hauv tebchaws (NEC).

3. Kev qhia tshwj xeeb ntawm XHHW -2 xaim 600v

Xhhw -2 xaim cov kev tsim kho kom muaj kev cia siab hauv kev mob hnyav:

Cov Khoom Siv Ua: Muaj nyob rau hauv aluminium lossis tooj liab. Aluminium cov qauv (piv txwv li, 300 MCM, 2 AWG) yog tus nqi-ua tau zoo rau cov haujlwm loj, thaum tooj liab muaj kev ua haujlwm zoo dua.

Kev rwb thaiv tsev: XLPE muab tshem tawm tsam mus rau kev puas tsuaj, cua sov (txog li 90 degree), thiab tshuaj lom neeg.

Kev Ntsuas Hluav Taws Xob: 600V, Haum rau kev faib khoom siv, kev pabcuam nkag rau hauv cables, thiab photovoltaic tshuab.

Qauv Ua Haujlwm: Ntsib UL 44, UL 854, thiab UL 1581, ua kom muaj kev sib xyaw nrog peb thiab cov hluav taws xob hluav taws xob.

4Cov. Cov ntawv thov nyob rau hauv ib puag ncig ntub dej

Xhhw -2}} thiab chaw ntub qhov chaw tshaj tawm ua rau nws zoo tagnrho rau:

Cov Nruab Nruab Nruab Nruab Nruab Nruab Nruab Nrab: Ncaj nrees hauv cov conduits rau sab nraum zoov teeb pom kev zoo lossis cov dej khov kho.

Cov Chaw Muaj Cov Vaj Tse: Xaim rau hauv cov nroj tsuag tshuaj lom neeg, cov chaw kho dej kom tsis muaj dej, lossis cov chaw nres nkoj.

Hnub Ci Fais Tshuab: Photovoltaic (PV) arrays nthuav tawm los nag, daus, thiab av noo.

Lub tsev lag luam: Kev pabcuam nkag nkag thiab pub rau cov khoom noj nyob hauv cov av noo lossis cov tsev vov tsev.

5. Qhov sib txawv tseem ceeb ntawm XHHW thiab XHHW -2

6. Xaiv cov xaim hluav taws xob zoo rau cov chaw ntub dej

Thaum xaiv ntawm XHHW thiab XHHHW -2}, xav txog:

Kev kis tau ib puag ncig ib puag ncig: Rau qhov noo noo, XHHW -2 yog yuav tsum tau.

Nqi vs. thiav: Xhhw -2} tej zaum yuav muaj tus nqi nce siab dua tab sis txo cov kev pheej hmoo tu ncua ntev.

Ntawv muaj: Qhia txog cov npe thiab nec ua raws li koj cheeb tsam.

7. Kev Lag Luam Cov Qauv thiab Ntawv Pov Thawj

Xhhw -2 xaim xaim raws txoj hlua khi kom haum:

UL 44: GUGSS THICKOSET-INSULATED cov xov hlau rau 600V-2000V siv.

Nec tsab xov xwm 310: Qhia cov lus qhia teeb tsa cov chaw ntub dej.

CSA Cov Qauv: Tau lees paub hauv Canada rau cov ntawv thov sib xws.

8. Cov Chaw Tso Khoom Chaw Tso Cai: Txhim khu kev qha xhhw -2} qhov chaw

Cov neeg tsim khoom zoo liQingdao Qingcang Technology Co., Ltd.(Suav teb) thiabNassau National Cable(Teb Chaws Asmeskas) Muab Ul-lees paub XHHW -2 cable. Cov khoom tseem ceeb muaj xws li:

300 MCM Aluminium Xhhw -2: $ 130 rau 50-1000 ft ntev, zoo tagnrho rau cov tshuab nyiaj siab hyperage.

2 AWG Aluminium Xhhw -2: $ 80 rau 100-1000 ft, siv hauv kev faib khoom.
