1. To taub XHHW hlau thiab nws cov ntawv thov
XHhw hlau yog tsim nrog cov polyethylene txuas nrog polyethylene (XLPE) thiab tiv thaiv dej nyob rau hauv cov xwm txheej ntub dej) thiab ua rau dej qhuav) thiab kev tawm tsam dej, tshav ntuj, thiab puas tsuaj. Nws cov kev sib txawv, xws liXhhw -2, tau ntsuas rau kev ncaj qha faus thiab cov muaj ib puag ncig zoo, ua rau lawv haum rau cov kev teeb tsa hauv av.
Cov Nta Tseem Ceeb
Ya raws tsis kam: XLPE rwb thaiv tsev txwv tsis pub cov dej ingress, tseem ceeb rau cov chaw ntub dej zoo li cov hauv paus, thiab sab nraum zoov.
Yam ruaj khov: Tsis txhob tawm ntawm kev txwv los ntawm roj, tshuaj lom neeg, thiab UV kis.
Tus nqi txiav txim siab: XHhw Hlau NqeTej ntsuas kev sib txawv raws cov ntsuas cua, ntev, thiab tooj / txhuas muaj pes tsawg leeg. Piv txwv li, tooj tus neeg tshaj tawm feem ntau los ntawm {{0}}}}}}}}}}}.
2. Kev ceev faj rau cov chaw ntub dej
A. Ua raws li cov cim hluav taws xob
Nec ua raws li: Ua raws cov xov xwm hluav taws xob hauv tebchaws (NEC) tsab cai 310, uas ua rau cov rwb thaiv tsev tshwj xeeb thiab cov hau kev teeb tsa rau cov chaw ntub dej. Piv txwv li,Xhhw -2yog pom zoo rau kev pom zoo ntub thiab qhuav, nyob rau tus qauv XHHW yuav xav tau kev tiv thaiv ntxiv.
Kev Siv GFCI Kev Tiv Thaiv: Hauv cov cheeb tsam tau mus rau qhov raug mob
B. Qhov kev xaiv kev xaiv kom tsim nyog thiab kev sib khi
Cov tshuaj tiv thaiv dej tsis muaj dej: Siv cov khoom siv nruj hlau hlau (RMC) lossis PVC Conduits ntsuas ntsuas rau kev siv hauv av. Ua kom ntseeg tau cov pob qij txha tau sib khi nrog cov dej sib txuas tsis muaj dej tsaws tsag los tiv thaiv kev ua dej noo.
Direct Hais Qhov Tsis Txaus Siab: RauXHhw Hlau Underground, Bury cables tsawg kawg 18-24 nti kom tob, nyob ntawm cov lej hauv zos. Siv cov lus ceeb toom kab xev saum toj no cov trench kom tsis txhob muaj kev sib tsoo.
C. Ib puag ncig thiab kev tiv thaiv txhua yam
Zam kev puas tsuaj lub cev: Tiv thaiv kom tsis txhob muaj ntawm kev ua paug uas siv lub tes tsho condenuit hauv cov chaw siab. Piv txwv li, Industrial-qib Cables zoo liTC-ER XHHW HLAU(Tais cable, raug khiav) suav nrog cov khaub ncaws uas txhawb zog rau cov neeg kho tshuab nyiaj.
Kev Tswj Kub: Xyuas kom ntseeg tau huab cua kub tsis tshaj li tus ntaus ntaus nqi thermal. Hauv cov chaw uas ua ke, muab qhov cua tso rau kom muaj cua sov dissipate.
D. Cov tswv yim noo noo ntawm cov tswv yim
Kev tiv thaiv kev ua xeb: Siv Dielectric roj rau kev sib txuas los tiv thaiv oxidation, tshwj xeeb tshaj yog cov av noo lossis chaw ntug dej hiav txwv.
Nce mounting: Nruab hnub sib tshuam ua ke thiab kho kom haum rau theem dej muaj peev xwm saum toj no. Piv txwv li, lub teeb ci nthab ntaus nqi rau cov chaw ntub dej yuav tsum tau teeb tsawg kawg 12 ntiv taw saum toj no cov dej sawv ntsug.
3. Cov kev txiav txim siab tshwj xeeb rau kev teeb tsa hauv av
Txhim KhoXHhw Hlau UndergroundYuav tsum tau cov kev tiv thaiv ntxiv vim av acidity, thiab av ua si.
A. trenching thiab backfilling
Qhov tob yuav tsum: Ua raws NEC rooj 300.5 rau tsawg kawg kev faus neeg tob. Piv txwv li, cov voj voog vaj tse yuav tsum muaj 18 ntiv tes npog thaum siv PVC conduit.
Cov Khoom Siv Khoom Noj Khoom Haus: Siv xuab zeb lossis pob zeb rau Cushion lub cable thiab txhim kho cov kua dej, txo cov dej hydrostatic siab.
B. Rodent thiab Kev Tiv Thaiv Hauv Paus
Armored Cables: Xaiv rauXhhw -2Nrog hlau-braided armor nyob rau thaj chaw kis rau nas kev puas tsuaj.
Lub hauv paus thaiv kev: Nruab lub cev thaiv kev nyob ze ntoo kom tiv thaiv cov hauv paus nkag mus rau hauv cov khoom.
4. Tus nqi thiab cov khoom siv ua kom zoo
Kev to taubXHhw Hlau Nqeyam yuav pab sib npaug nyiaj txiag thiab kev ua tau zoo:
Tooj liab vs. Aluminium: Tooj liab muaj cov kev coj zoo dua tab sis cov nqi 2-3 zaug ntau dua txhuas. Rau ntev sau, txhuas yuav yog kev lag luam.
Ntsig Kev Yuav Khoom: Cov chaw muag khoom uas zoo li tsim cov nyiaj cheb-Suav rau kev txiav txim siab tshaj 500 meters, txo cov nqi ib-.
5. Txawv XHHW, XHHW -2}, thiab tc-er xhhw
Xhhw -2: Rated rau 90 degree nyob rau hauv ob qho tib si ntub thiab qhuav cov xwm txheej, zoo tagnrho rau kev ncaj thiab ib puag ncig zoo.
Tc-er xhhw: Tais cable (raug khiav) variant tsim rau cov tais khoom, muab tau yooj yim thiab zuaj tsis kam.
Hauv Asmeskas cable lag luam,Dongguan Ntau Ntau Hlau & Cable Co., Ltd.Tus nqi nqe thiab ntawv pov thawj zoo yog qhov tseem ceeb.
