1. To taub XHHW Hlau: Cov Lus Qhia Tshwj Xeeb thiab Cov Qauv
XHHW (Cross-txuas Polyethylene muaj kev tiv thaiv cov dej kub siab-resistant) hlau yog qhov ntsuas dav hlau tsim rau cov chaw nyob thiab cov ntawv thov kev lag luam. TusXhhw -2 Kab hlau specificationKev txhais tau ib qho kev hloov kho tshiab nrog cov khoom siv cua sov thiab cov neeg kho mob, ua rau nws zoo rau cov chaw sib tw zoo li cov nce siab.
Cov Ntsiab Lus Tshwj Xeeb ntawm XHHW -2 xaim hlau
Rwb thaiv tsev ntaub: Hla nrog polyethylene (xlpe) ua kom zoo dua li ntawm 90 degree hauv cov kev mob thiab 75 degree hauv cov chaw ntub dej).
Kev Ntsuas Hluav Taws Xob: Feem ntau ntsuas rau 600V, haum rau lub zog thiab teeb pom kev zoo ncig ua lag luam hauv cov tsev lag luam.
Tus saib xyuas: Muaj nyob rau hauv tooj liab lossis txhuas, nrog stranded lossis cov khoom tsim kho rau kev hloov pauv thiab siv zog.
Kev ceev kev cai: Ntsib UL 44, UC 83, thiab Code hluav taws xob hauv tebchaws (NEC), kom muaj kev nyab xeeb thiab kev nyab xeeb.
TusXhhw -2Kev sib txawv yog tsim los kom tau cov kev mob siab dua thiab txias dua li cov qauv XHHW, yog qhov uas kub ua kom sov thiab noo noo qhov tshwm sim yog ib qho.
2. Kev ua tau zoo ntawm xhhw lub tsev hlau
High-aw vaj tse xav tau txoj kev siv hluav taws xob uas sib npaug kev nyab xeeb, thanevity, thiab ua tau zoo. Ntawm no yog li casXhhw tus cwj pwmExcel:
A. Thermal stability thiab hluav taws tsis kam
XLPE rwb thaiv tsev hauv xhhw -2 hlau muaj cov tshwj xeeb tiv thaiv kev cuam tshuam thermal. Cov cuab yeej no tseem ceeb heev nyob rau hauv high-nce ntau zaus khiav los ntawm cov riser safts muaj kev sib tw ua kom sov. Tsis zoo li PVC-insulated xov hlau, xhhw tswj hwm kev ncaj ncees txawm nyob rau ntawm cov kub, txo cov kev pheej hmoo kub.
B. Ya noo thiab Tshuaj Lom Zem
Lub tsho tiv thaiv dej-resistant ntawm xhhw hlau ua kom cov hlau xaim txhim khu kev qha nyob rau hauv Dowamp ib puag ncig, cov chav tsev ua ke. Tsis tas li ntawd, nws txoj kev tiv taus roj, cov kuab tshuaj, thiab cov kua qaub ua rau nws haum rau cov ntu muaj kev lag luam.
C. kev siv hluav taws xob
Kev teeb tsa siab xav tau cov xov hlau uas tuaj yeem ua kom lub cev muaj kev ntxhov siab thaum thiab tom qab kev teeb tsa. XHhw rwb thaiv tsev tsis yeem tiv thaiv kev puas tsuaj, kev tsoo, thiab kev cuam tshuam, txo qhov kev pheej hmoo ntawm kev puas tsuaj hauv kev ua kom zoo.
D. Yooj Thiab Yooj Yim Ntawm Kev Teeb
Stranded Xhhw tus cwj pwm muaj kev hloov pauv, qhov yooj yim los ntawm cov chaw txav nruj-ib qho kev sib tw hauv cov vaj tse ntau. Qhov no txo cov nqi zog thiab sijhawm ua haujlwm.
3. Cov ntawv thov nyob rau hauv cov tsev siab
Qhov tshwj xeeb xav tau ntawm high-nce-sawv kev faib khoom, kev nyab xeeb kev nyab xeeb, thiab txuag hluav taws xob-ua xhhw {} xaim xaiv ib qho kev xaiv xhhwred.
A. Ntsug Riser Systems
High-nce toj siab rau cov kab ke ntsug los faib lub zog ntawm cov plag tsev. XHHW lub teeb liab tseem tsis tau muaj cov qauv siv nyiaj txiag uas ua rau cov neeg tua hluav taws thiab xoom cov ntaub ntawv (LSZH)
B. Thaum muaj xwm ceev thiab lub neej nyab xeeb
Lub tswb hluav taws kub, teeb pom kev zoo thaum muaj xwm ceev, thiab cov pa hluav taws xob hauv siab xav tau cov xaim uas tseem ua haujlwm thaum muaj xwm txheej ceev. Xhhw -2 '}' Tsis muaj peev xwm ua haujlwm nyob rau hauv siab kub ua kom muaj kev nyab xeeb, tseem ceeb rau kev nyab xeeb nyob hauv siab.
C. Zog-txuag hluav taws xob
Niaj hnub niaj hnub ntau-nce ntxiv ua ntej lub zog txuag hluav taws xob. XHHW lub impedance qis txo lub zog poob dhau qhov kev ncua deb, txhawb nqa cov hom phiaj tsim nyog. Qhov no ua raws li cov qauv no hauv kev nce qib siab, xws li cov uas pom hauv cov tsev txias-cheeb tsam uas muaj zog noj yog qhov tseem ceeb.
4. Ua txoj cai nrog cov cim kev ua haujlwm siab
Hluav taws xob hauv cov hluav taws xob yuav tsum ua raws li cov lis dej num nruj, xws li NEC, txoj cai tsim tsev thoob ntiaj teb (thiab cov cai hauv zos. Xhhw -2 xaim xaim sib ntsib los yog tshaj li cov kev xav tau no:
Nec tsab xov xwm 310: Qhia cov kev ntaus kub thiab cov rwb thaiv tsev rau cov tais hauv tsev, uas xhhw -2 txaus.
Cov Qauv Kev Nyab Xeeb Kev Nyab Xeeb: Ua raws li NFPA 70 thiab 72 rau hluav taws kub uas siv hluav taws xob hauv nruab xwm ceev.
Seismic kev ua tau zoo: Thaum hos tsis muaj feem cuam tshuam nrog xaim, siab nyob hauv av qeeg hauv av qeeg yuav tsum tau hloov tau thiab ruaj khov. XHhw lub tshuab thev naus laus zis txhawb cov qauv kev ruaj khov thaum lub sijhawm pom kev tshwm sim.
5. Kev Tshawb Fawb Kev Lag Luam thiab Kev Lag Luam Tiam
Thaum lub sij hawm cov ntaub ntawv tshwj xeeb ntawm XHHW hauv cov nce siab yog txwv, dav dav dav hauv kev xaiv cov xaim xaim xaiv nws cov khoom siv loj hlob:
Kev Ua Lus Qhia thiab Cov Qauv Siv: Cov txuj ci ceev ceev cov tswv yim, raws li pom hauv cov phiaj xwm zoo li C-Tsev, tau txais txiaj ntsig los ntawm XHHW qhov yooj yim ntawm kev sib koom ua ke.
Cov tsev ntse: Qhov nce ntawm iot-enabled cov tshuab nyob rau hauv high-rises xav tau txhim khu kev qha wireing rau cov ntaub ntawv thiab kev sib xyaw ua ke. Xhhw lub suab nrov-resistant cov khoom txo qis dua hluav taws xob cuam tshuam hluav taws xob.
Kev Txhawb Nqa Kev Ncaj Ncees: Xhhw dlhos nrog cov hom phiaj leds los ntawm kev txo cov khoom siv hluav taws xob thiab siv cov khoom siv rov ua dua tshiab.
