1.Thiab Xhhw hlau: muaj pes tsawg leeg thiab cov ntawv thov
XHHW (Cross-txuas Polyethylene muaj kev kub siab-resistant dej-resistant) hlau yog ib puag ncig ntub thiab qhuav. Nws cov rwb thaiv tsev muaj cov polyethylene (xlpe), uas muaj cov xwm txheej ntub dej (XLPE) Cov khoom no ua rau nws xaiv tau rau lub zog faib rau kev ua lag luam, kev lag luam, thiab vaj tse.
Cov ntawv thov feem muaj xws li:
Kev Pabcuam Kev Ua Haujlwm Saib Xyuas
Vaj huam sib luag cov neeg ua haujlwm
Ceg Npe
Muaj Machinery
Tab sis ua qhov no txhais lus rau kev sib tham?
2.telecomermunications infrastructure: tshwj xeeb yuav tsum tau
Cov xov tooj sib txuas lus ua ntej lub cim kev ncaj ncees, hluav taws xob cuam tshuam (EMI) tsis kam, thiab ua raws li cov qauv tsawg-voltage. Tsis zoo li cov xov hluav taws xob hluav taws xob ntau zaus nqa cov ntaub ntawv lossis lub suab cim qhia ntawm qhov hluav taws xob hauv qab 50v, yuav tsum tau tiv thaiv thiab kho kom haum.
Cov kev txiav txim siab tseem ceeb rau Telecom Xov:
Daim thaiv: Txhawm rau txo qis EMI los ntawm cov kab ze ntawm lub hwj chim.
Kev Ntsuas Hluav Taws Xob: Feem ntau 300v lossis tsawg dua rau cov ntawv thov tsawg.
Yooj yooj: Yooj yim ntawm kev teeb tsa hauv cov chaw nruj.
Qauv Ua Haujlwm: NEC tsab xov xwm 800 (kev sib txuas lus ncig) thiab arti / tia -568}} rau kev sib txuas.
Muab cov kev xav tau no, XHhw lub luag haujlwm XHHW tseem ceeb hauv kev sib tham hauv Telecom tau muab lub zog ncaj qha rau cov khoom siv sib txuas lus dua li xa cov paib.
3.xhhw xaim hauv Telecom: Siv cov ntaub ntawv thiab cov kev txwv
Thaum XHHW tsis tsim rau cov ntaub ntawv kis, nws plays lub luag haujlwm tseem ceeb hauv kev txhawb nqa xov tooj cua:
3.1 Cov Khoom Siv Hluav Taws Xob
Telecom Hubs, cov chaw zov me nyuam, thiab xov tooj ntawm tes xav tau kev txhawb nqa lub zog hluav taws xob txhim khu kev qha. Xhhw cables zoo li1aj 2awg Xhhwthiab3 / 0 xhhw tooj liab 600vyog qhov zoo tagnrho rau:
Backup Generator Sib txuas
Uninterruptible zog mov (ups) tshuab
Cov Khoom Noj Kub Tam Sim No Tam Sim No Rau Telecom Khoom
Piv txwv li,4 / 0 xhhw hlau(A {0000 AWG Tooj Liab Tus Thawj Coj) tuaj yeem ua rau 260A ntawm 75 degree, ua nws haum rau hnyav-zog cirity nyob rau hauv cov chaw loj hauv xov tooj.
3.2 Sab nraum zoov thiab hauv av conduits
Telecom kev teeb tsa feem ntau koom nrog sab nraum zoov lossis faus cov khoom noj. XHHW cov dej-tiv taus XLPE rwb thaiv tsev ua kom muaj kev ua kom muaj kev ua kom ntub dej hauv qhov chaw ntub dej. Txhuas Kev Xaiv Zoo li500mcc xhhw txhuasMuab cov tshuaj zoo rau kev daws teeb meem rau kev deb-deb lub zog sau vim yog txhuas lub teeb yuag.
3.3 Hybrid Hwj Chim-Cov ntaub ntawv nruab
Hauv cov chaw ua ke ua ke ua ke nrog lub zog thiab cov kab hluav taws xob tsawg, XHHW tuaj yeem ua ke yog tias cov lus qhia txog cov ntaub ntawv (piv txwv li} nti nti) tau ua raws li tiv thaiv kev cuam tshuam.
4.Key brheyw cov khoom lag luam rau kev txhawb nqa
Cia peb tshuaj xyuas qhov tseeb tias UHW cov khoom lag luam nrog kev xav tau telecom:
4. {{1 1 AWG 2Wg Xhhw
Cov Ntawv Thov: Lub zog thib ob faib rau kev sib tw sib tw, cov chaw me me.
Qhov Zoo: Compact loj, 600V ntsuam xyuas, thiab yoog raws rau conduit bends.
Kev txwv: Tsis thaiv cov ntaub ntawv kis.
4. {{2 3 / 0} xhhw tooj liab 600v
Cov Ntawv Thov: High-basing beeders, cov tshuab hluav taws xob govours.
Qhov Zoo: Tooj liab lub siab (100% ICS) ua kom muaj zog heev tshaj plaws.
Nec ua raws li: Rated rau 225a ntawm 75 degree (NEC rooj 310.16).
4. {{{3 4 / 0 xhhw hlau
Cov Ntawv Thov: Kab hwj huam tseem ceeb rau Telecom Hubs.
Lub peev xwm: 260A ntawm 75 degree, haum rau loj-teev nruab.
4. {{4 500 mcm xhhw txhuas
Cov Ntawv Thov: Nqi siv hluav taws xob kom zoo tshaj li 200+ ko taw.
Cov txiaj ntsig: Aluminium tus nqi qis thiab hnyav vs. tooj liab.
Kev txiav txim: Yuav tsum tau cov khoom loj dua vim yog txhuas qhov qis dua.
5.pliance thiab kev txiav txim siab nyab xeeb
Thaum XHHW HLAU PIAV NOJ RAU NECTEMS RAU COV NTAUB NTAWV HAIV NEEG (Tshooj 310), Telecom Instuments thov kom muaj dua CODE:
Sib cais los ntawm cov ntaub ntawv cables: NEC 800.133 (A) Mes Ua kom lub cev sib cais lossis kev thaiv ntawm cov kab mob fais fab thiab kev sib txuas lus.
Kev txwv feem ntau: XHhw tiam 600V tshaj qhov chaw telecom voltages tab sis tseem nyab xeeb rau lub zog muaj zog.
Kev Ntaus Ib Puag Ncig: Xhhw -2 (UL-rated rau cov chaw ntub) yog qhov nyiam rau kev sib tw hauv xov tooj cua.
6.CoCov thiab Aluminium hauv Telecom Hwj Huam
Xaiv ntawm tooj liab thiab txhuas XHHW nyob ntawm cov phiaj xwm:
| Yam tseem ceeb | Tooj liab (piv txwv li, 3 / 0 xhhw) | Aluminium (xws li, 500mcm xhhw) |
|---|---|---|
| Kev coj ua | Siab dua (zoo dua rau kev sau luv luv) | Qis dua (yuav tsum tau txais lub ntsuas cua loj) |
| Tus nqi | Kim dua | Kev Siv Nyiaj Txiag |
| Qho hnyav | Hnyav dua | Lub teeb yuag |
| Kev txiav hlo | Yooj yim sib txuas | Yuav tsum muaj cov kab mob antioxidant |
Rau Telecom thaub qab cov tshuab ua ntej kev cia siab, tooj liab feem ntau nyiam. Rau kev tawm ntawm kev hle, cov nqi txhuas kev txuag nyiaj yuav ua pov thawj nws siv.
7.Installation kev coj ua zoo tshaj plaws
Txhawm rau ua kom tiav XHHW cov txiaj ntsig zoo hauv kev sib tw:
Siv nws yog xim hlau conduits rau EMI kev thaiv.
Sau npe rau lub zog thiab cov ntaub ntawv cables kom meej meej kom tsis txhob muaj kev ntxhov siab.
Ua raws li cov torque specifications rau cov nyom los tiv thaiv txoj kev sib txuas xoob.
Ntsuas rwb thaiv tsev rwb thaiv tsev tsis kam tshaj tawm tom qab (ib qho ansi / neta atts -2017).
