Dab tsi yog cov khoom muaj peev xwm tam sim no ntawm XHHW hlau?

1. Kev ntsuas ntawm XHHW hlau

Xhhw sawv rau "Hla Polyethylene siab kub-resistant waterproof." Nws muaj tus cross-txuas polyethylene (xlpe) rwb thaiv tsev, uas yog 75 degree rau noo noo, tshuaj lom neeg, thiab kev puas tsuaj rau lub cev. Qhov no ua rau nws haum rau siv nyob rau hauv conduits, cable cov tais, thiab qhia ncaj qha faus cov ntawv thov.

Cov yam ntxwv tseem ceeb muaj:

Kev Ntsuas Hluav Taws Xob: Feem ntau yog rated rau 600V lossis 1000V, nyob ntawm Rwb thaiv tsev tuab thiab daim ntawv thov yuav tsum tau ua.

Cov Ntawv Qhia Cov Ntawv: Muaj nyob rau hauv tooj liab lossis txhuas. Aluminium XHHW yog sib dua thiab ua tau zoo dua tab sis yuav tsum tau tus neeg xyuas tsiaj ntau dua kom phim tooj liab lub peev xwm tam sim no.

Xhhw -2 variant: Tsim rau cov cua kub siab dua (txog li 90 degree hauv ntub lossis qhuav cov xwm txheej), ua rau nws zoo tagnrho rau qhov chaw hnyav.

2. Tam sim no-nqa muaj peev xwm: yam tseem ceeb

Cov khoom muaj peev xwm tam sim no ntawm XHHW hlau nyob ntawm ntau yam hloov pauv:

A. Tus neeg saib xyuas loj thiab cov khoom siv

AWG (American Hlau Galai): Me AWG lej qhia txog cov neeg saib xyuas loj. Piv txwv li,8 AWG XHHWMuaj ib thaj chaw loj dua li 10 odg, tso cai ntws tshiab dua.

Tooj liab vs. Aluminium: Tooj coj hluav taws xob muaj hluav taws xob ntau dua, muaj kwv yees li 61% ntau dua kev ua haujlwm tshaj txhuas. Yog li, txhuas cov cooj txwv yuav tsum muaj ntsuas loj dua kom ua tiav qhov muaj peev xwm tam sim no. Piv txwv li, muaj 8 AWG Aluminium XHHW hlau yuav muaj cov ampac nyob hauv qis dua piv rau nws cov counper tooj liab.

B. Voltage ntsuam xyuas

600V vs. 1000V: Cov rwb thaiv rwb thaiv cov tuab nce ntxiv rau cov kev ntsuas siab dua. Thaum lub sijhawm no tsis ncaj qha rau ampacity, nws ntseeg tau kev nyab xeeb hauv kev ntxhov siab hauv qib hluav taws xob ntau dua. Piv txwv li,8 AWG XHHW Cable 1000VTej zaum yuav muaj cov rwb thaiv tsev tuab dua li 600V variant, tab sis nws cov peev xwm tam sim no tseem khi rau tus neeg saib xyuas loj thiab cov khoom siv.

C. Cov huab cua sov thiab cov teeb meem installi

Kub: Kev nce siab ambient kub txo txoj hlua cable muaj peev xwm los ua kom muaj cua sov dissipate, tsim nyog tau muab kho kom sov, tsim nyog tau muab kho kom muaj cua sov, tsim nyog muab nqis los. Xhhw -2, ntsuas rau 90 degree rau txhua qhov xwm txheej, outperforms txheem Xhhw hauv qhov chaw siab.

Txoj kev teeb tsa: Bundling ntau cov cables lossis muab lawv rau hauv cov khoom noj uas txwv tsis pub muaj huab cua, nce cov thermal tiv thaiv thiab txo cov pa thermal tsis kam thiab txo cov ampacity. Piv txwv li, NEC cov lus 310.16 qhia meej derating cov lus qhia txog kev sib sau ntau.

D. Cov Qauv Kev Cai

NEC (National Electrical Code): Muab cov ntawv ampacity rooj raws li cov khoom siv coj, qhov loj me, thiab hom thaiv thaiv thaiv. Rau8 AWG Tooj Liab Xhhw, Nec-ntsuas ampacity feem ntau yog 50A ntawm 75 degree, thaum txhuas XHHW yuav nyob qis qis dua.

3. Tam sim no-nqa lub peev xwm ntawm 8 AWG XHHW hlau

A. tooj liab xhhw

Kev thov 600v: Ntawm 75 degree, 8 Awg Tooj Liab XHHW txhawb nqa nce txog 50a. Qhov no foob cov kab nruab nrab hauv tsev, HVAC tshuab, thiab kev lag luam tshuab.

1000V Daim Ntawv Thov: Qhov kev ntsuas siab ntau dua tsis hloov Ampacity tab sis ua kom ua raws li cov kev ua tiav cov kab ke yuav tsum muaj kev sib koom ua ke ntau.

B. Aluminium Xhhw thiab Xhhw -2

Aluminium XHHW: Vim muaj ntau dua resistivity, 8 AWG Aluminium XHHW feem ntau nqa 40a ntawm 75 degree, yuav tsum tau ua tib zoo thauj khoom kom tsis txhob muaj kev kub ntxhov.

Aluminium Xhhw -2: Nrog cov cua sov ua kom tsis kam, cov kev tswj hwm ruaj khov nyob hauv ib puag ncig muaj kev ruaj khov, ua rau nws haum rau hnub teb ua liaj ua teb thiab kev teeb tsa hnub ci thiab sab nraum zoov.

4. Kev sib piv: tooj liab thiab Aluminium XHHW

5. Kev txiav txim siab ua rau kev teeb tsa

Tso tseg: Txhuas ntau dua resistivity disticity voltage poob dhau qhov kev ncua deb. Them los ntawm kev siv cov neeg saib xyuas loj dua lossis cov neeg luv dua.

Kev txiav: Aluminium yuav tsum muaj cov tshuaj tiv thaiv oxidant kom tiv thaiv corrosion ntawm cov ntsiab lus sib txuas.

Environmentalency: Rau sab nraum zoov lossis cov chaw ntub dej, XHHW -2 '}'} '}'} '}
