1. Nkag siab XHHW Cable: LAWV THIAB COV NYIAJ
XHHW (Cross-txuas Polyethylene muaj kev tiv thaiv cov khoom siv hluav taws xob ntau ntxiv los ntawm nws lub peev xwm los tiv thaiv ntau dua (txog li 90 degree). Tus rwb thaiv tsev XLPE muab kev tiv thaiv zoo tshaj plaws rau cua sov, noo, kev puas tsuaj rau cov ib txwm ua hluav taws xob cov tshuaj uas rhaub kom zoo li PVC.
Cov Nta Tseem Ceeb Ntawm Xhhw Rwb Thaiv Tsev
Thermoset Khoom: Tsis zoo li thermoplastic cov ntaub ntawv, XLPE tsis yaj nyob rau hauv siab, ua rau nws zoo rau ib puag ncig hnyav.
Dej tiv: Tus "W" nyob hauv XHHW kos npe rau nws cov haum rau cov chaw ntub, suav nrog cov khoom noj hauv qab lossis sab nraud hauv qee yam.
Yam ruaj khov: Xhhw cov tuab rwb thaiv tsev txheej tiv thaiv cov kev ntxhov siab, UV hluav taws xob, thiab ib puag ncig kev tsis pom zoo.
Qhov kev sib xyaw no ntawm cov khoom ua rau XHhw tus neeg sib tw ua rau kev sib tw hauv av, tab sis cov txheej txheem tshwj xeeb yuav tsum tau ua raws li kev nyab xeeb thiab ua raws.
2. XHHW hauv kev nqis tes: kev coj ua zoo tshaj plaws rau kev siv hauv av
Txhim kho XHHW hauv kev conduit yog ib txoj kev feem ntau rau cov ntawv thov hauv av. Conduits tiv thaiv cov kab mob lub cev, cov dej noo, thiab cov kev ntxhov siab ib puag ncig.
Qhov Zoo ntawm Cov Tshuab Cias
Kev Tiv Thaiv Txhua Yam: Conduits Shield XHHW los ntawm kev tsoo, nas kev puas tsuaj, thiab kev txav hauv av.
Thaum tshav sov tsis kam: Cov cerked kom zoo yog ua kom muaj kev phom sij, txo qhov kev pheej hmoo ntawm overheating. NEC Cov lus qhia pom zoo tshaj plaws sau 40% rau ib leeg.
Kev ceev kev cai: CONDUKS Kev Txhim Kho Kom Ua Haujlwm Zoo Ua Si nrog rau cov qauv hluav taws xob hauv tebchaws (NEC) cov qauv, uas feem ntau yuav tsum tau siv rau cov xaim hauv av muaj kev pheej hmoo.
Kev sib tw
Tus nqi thiab ua haujlwm: CARTUS Installation yuav tsum tau cov ntaub ntawv ntxiv thiab ua haujlwm piv txwv rau kev faus neeg.
Kev pheej hmoo corrosion: Cov khoom siv hlau hlau hauv cov av hauv cov xeb yuav txwv tsis dhau sijhawm, tsim nyog tsis yog xim hlau lwm txoj kev zoo li PVC.
Rau xhhw hauv cov conduit system, xyuas kom cov conduit yog ntsuas rau kev siv hauv av thiab ua raws li cov lej hauv zos.
3. Yuav siv xhhw siv rau kev faus yuam kev?
Cov lus nug ntawm"Xhhw Hlau Ncaj Ncees"hinges ntawm lub cable siv thiab cov cai hauv zos. Thaum tus qauv XHHW tsis muaj kev sib cav sib ceg rau kev ncaj qha faus, nws txhim kho kev sib txawv,Xhhw -2, yog tsim meej meej tsim rau lub hom phiaj no.
Xhhw -2 thiab lwm yam qauv XHHW
Qhov Ntsuas Kub: Xhhw -2 tswj tau 90 qhov kev ntsuam xyuas qib 90 degree hauv ob qho chaw ntub thiab qhuav, whereas cov qauv xhhw yuav muaj cov kev ntsuas ntub dej.
Rwb Thaiv Tsev Thickness: Xhhw -2 Ntau zaus thicker xlpe rwb thaiv tsev, txhim kho kom av acidity thiab noo noo.
Ntawv muaj: Saib rau UL-sau xhhw -2 luables, uas sib ntsib nruj rau cov qauv kev nyab xeeb hauv av.
Cov txheej txheem kev coj ua ncaj qha
Qhov tob yuav tsum: Bury cables tsawg kawg 18-24 nti kom tob, nyob ntawm cov lej hauv zos.
Kev pw thiab backfill: Siv xuab zeb lossis cov av zoo rau Cushion lub cable thiab tsis txhob muaj pob zeb ntse.
Kev cim: Nruab daim ntawv ceeb toom saum toj no rau kev tiv thaiv kev puas tsuaj rau kev puas tsuaj thaum lub sijhawm excavation.
4. XHHW MC CABLE: Ib qho kev daws teeb meem rau cov hluav taws xob hauv av
Hlau-Clad (MC) Cable sib koom ua ke XHhw tus nais nrog cov hlau tiv thaiv, muab cov tshuaj tiv thaiv zoo rau qhov chaw nyuaj.
Cov txiaj ntsig ntawm XHHW MC cable
Kev Tiv Thaiv Txhim Kho: Cov hlau sib tsoo tiv thaiv kev cuam tshuam, kev xeb, thiab hluav taws xob hluav taws xob (EMI).
Yooj yooj: MC cable tuaj yeem siv rau hauv ob chav conduit thiab ncaj dua cov ntawv thov faus, tab sis yuav tau ntxiv ntxiv rau tom kawg.
EMI Tiv Thaiv: Qhov zoo tagnrho rau cov chaw muaj kev lag luam nrog cov tshuab hnyav, qhov twg EMI yuav cuam tshuam kev ncaj ncees.
Kev txwv
Tus nqi: MC cable yog kim dua tus qauv XHHW.
Kev teeb tsa nyuaj: Yuav tsum tau cov txuas tshwj xeeb thiab cov cuab yeej rau kev txiav.
5. Rwb thaiv tsev kev ua haujlwm: vim li cas xhhw excrels nyob hauv av
Tus"Xhhw rwb thaiv tsev"Puas yog nws txhais tau cov lus qhia, ua kom muaj kev txhim khu kev qha hauv cov chaw subterraneees.
XLPE thiab PVC RWB THAIV TSEV
Thermal ruaj khov: XLPE khaws nws cov qauv txheej txheem kev ntseeg siab dua ntawm qhov kub siab dua, txo txoj kev pheej hmoo ntawm rwb thaiv tsev rwb thaiv tsev.
Tshuaj Kuj: XLPE tiv cov roj, acids, thiab alkalis uas pom nyob hauv av.
Kev muaj peev xwm: Xhhw lub rwb thaiv tsev muaj lub neej ntev dua li pvc, ua rau nws muaj txiaj ntsig zoo sijhawm.
Kev Kawm Txog: UL-sau xhhw {{1} lingdao ua yeeb yam li xingdao ua ntej Xingdao Ua Raws Li Cov Qauv Nyuaj Siab, suav nrog UL 400 thiab NEC ua raws.
6. Ua raws cai thiab kev txiav txim siab nyab xeeb
Adhering rau cov xov tooj hluav taws xob yog qhov tseem ceeb rau kev teeb tsa hauv av. Cov ntsiab lus tseem ceeb muaj xws li:
Nec tsab xov xwm 310: Qhia cov kev ntsuas kub thiab kub thiab rwb thaiv tsev hom rau kev xaim hauv av.
UL daim ntawv pov thawj: Tswj cov cable daws teeb meem hluav taws thiab kev ua tau zoo.
Cov cai tswjfwm hauv zos: Ib txwm sab laj cheeb tsam cov cim rau qhov ua kom tob, thiab kev cog lus conduit.
7. Xhhw vs. sib tw cables: thhn thiab siv -2
Hwj chim
Zoo: Tus nqi qis, thinner rwb thaiv tsev kom rub tau yooj yim.
Nplij txwv: Txo qhov kub ntsuas (75 degree hauv cov chaw ntub) thiab cov rwb thaiv tsev tsawg.
Siv -2
Zoo: Tsim qauv rau ncaj qha faus thiab av cov kev pab nkag nyob hauv av.
Nplij txwv: Txwv tsis muaj yooj thiab tus nqi siab dua piv rau Xhhw -2.
Rau feem ntau cov haujlwm hauv av feem ntau, xhhw -2 strikes qhov zoo tshaj tshuav ntawm kev ua tau zoo thiab tus nqi.
8. Cov lus qhia cov lus qhia rau xhhw nyob hauv av
Conduit kev xaiv: Siv pvc lossis corrosion-resistant hlau conduits.
Kev cog lus: Ua kom muaj kev tsim nyog los tiv thaiv kev ua txhaum.
Kev kuaj: Ua cov rwb thaiv tsev tiv thaiv kev ntsuam xyuas tom qab kev teeb tsa kom pom kev puas tsuaj.
