1. Kev sib piv ntawm cov hom phaj cable
Daim duab kab ntawv no pab koj xaiv cov cable uas tsim nyog tshaj plaws rau cov phiaj xwm tshwj xeeb xws li tshav kub dissipation, thauj khoom muaj peev xwm, thiab hom cable.
| Yam zoo | Lawb Tais | Perforated / trough tais | Khoom hauv qab tais | Hlau Mesh / Pob tawb Tais |
| Lub tsev | Muaj ob sab kev tsheb ciav hlau sib txuas los ntawm cov series ntawm rungs, zoo ib yam li tus ntaiv. | Nta cov khoom siv cov khoom haum nrog cua qhib (qhov chaw lossis qhov). | Ib tug tag nrho cov tais nrog ib qho khoom siv, puag txuas ntxiv thiab tsis muaj qhib. | Ib daim phiaj - zoo li cov qauv tsim los ntawm welded steel hlau. |
| Qhov Zoo | 1. Kev kub kub zoo heev. 2. Cov load siab tshaj plaws - bearing muaj peev xwm. 3. Yooj yim kom muaj kev ruaj ntseg cable nrog kev sib txuas lossis ua ke. |
1. Cov cua sov zoo tsis txaus. 2. Muab kev txhawb nqa txuas ntxiv rau cov cables. 3. Muaj kev tiv thaiv ntau dua li tus ntaiv tais. |
1. Muab kev tiv thaiv siab tshaj rau cov kab sib txawv. 2. Zoo emi / rfi tiv thaiv. |
1. Kev hloov tau yooj yim; Yooj yim khoov, txiav, thiab cov duab ntawm - chaw. 2. Lub teeb yuag thiab nrawm rau nruab. |
| Tsis zoo | Muab kev txhawb nqa tsis zoo rau me me - txoj kab uas hla, uas tuaj yeem soag ntawm rungs. | Muaj cov cua sov tsawg dua thiab ua kom muaj peev xwm piv rau cov tais tais. | 1. Tsis muaj cua sov tshaj plaws. 2. Noo noo thiab cov khib nyiab tuaj yeem nthuav tawm sab hauv. |
1. Tus nqi qis tshaj plaws - cov kabmob muaj peev xwm. 2. Muab cov ntsiab lus tsis zoo rau cables. |
| Zoo tshaj plaws rau | Lub zog hluav taws xob, loj - dexeter tswj cable, thiab cov ntawv thov uas xav tau ntev spans thiab cov khoom hnyav. | Kev sib xyaw ua ke ntawm me me rau nruab nrab - Txoj hau hluav taws xob thiab tswj cov cable tsis muaj txiaj ntsig. | Rhiab cov cuab yeej, fiber ntau optic, lossis cov ntaub ntawv xaim uas xav tau kev tiv thaiv ntau tshaj plaws thiab tiv thaiv los ntawm kev cuam tshuam. | Cov ntaub ntawv cov chaw, cov chaw rau neeg rau zaub mov, lub teeb {{{{{} Lub luag lus qhib kev sib tham hauv xov tooj, thiab kev teeb tsa nrog cov kev coj ua. |

2. Cov Cable Cable Installation yuam kev & Kev Tiv Thaiv
Cov npe no qhia txog cov teeb meem nquag pom thaum nrhiav chaw thiab txais kev lees paub, pab koj txhim kho txoj haujlwm zoo thiab kev nyab xeeb los ntawm kev daws lawv tau ua.
Yuam kev 1: Tsis raug lossis ntau dhau kev txhawb nqa
Qhov tseem ceeb:Cov tais zaum nruab nrab ntawm kev txhawb nqa, tshaj nws cov kev txwv tsis pub cuam tshuam. Sijhawm dhau sijhawm, qhov no tuaj yeem ua rau muaj kev nkees nkees thiab tsis ua tiav.
Kev tiv thaiv:
Nruj me ntsis ua raws cov chaw tsim khoom thauj cov vs. Charur scort tshwj xeeb thaum tsim qauv thiab txhim kho kev txhawb nqa.
Yuav tsum muaj kev txhawb nqa ntxiv nyob rau hauv 30-60 cm (1-2 ft) ntawm ib qho haum, xws li luj tshib, tees, lossis hla.
Xyuas kom txhua tus txhawb txhua tus tau teeb tsa nyob rau tib lub dav hlau kom tiv thaiv kev ntxhov siab ntawm lub tais.
Yuam Kev 2: Tsis raug lossis tsis raug teeb tsa tus neeg dhia dhia
Qhov tseem ceeb:Cov hluav taws xob txuas ntxiv ntawm lub tais kab tawg, muab cov av nyab xeeb rau qhov tsis muaj kev nyab xeeb. Thaum lub sij hawm ua txhaum kev mob, lub tais tuaj yeem ua energized ntawm kev phom sij hluav taws xob tsis tau ua kom muaj kev nyab xeeb rau hauv av.
Kev tiv thaiv:
Qhia kom meej rau hauv cov ntaub ntawv teeb tsa uas "Bonding Jumpers yuav tsum tau txhua qhov tsis - Welded kev twb kev txuas txuas cov ntsiab lus."
Thaum soj ntsuam, kuaj tsis yog tsuas yog tias cov chaw sib tiv toj tau tshem tawm cov xim thiab cov nyom tau ruaj khov.
Siv qhov qis -}} Tsis kam Ohmmeter ntsuas qhov tsis kam ntawm ob qho chaw nyob deb ntawm lub tais; Tus nqi yuav tsum nyob ze rau xoom.
Yuam Kev 3: Txiav cov npoo sab laug tsis kho tom qab ntawm -}} chaw ntawm fabrication
Qhov tseem ceeb:Rau galvanized steel cov tais, txiav cov ntawv nthuav tawm cov hlau raw thiab rhuav tshem cov txheej tiv thaiv zinc. Qhov tsis muaj kev tiv thaiv ntug dhau los ua qhov pib rau xeb thiab xeb, uas tuaj yeem kis tau thiab txo cov tais lub neej ua haujlwm.
Kev tiv thaiv:
Yuav tsum muaj tus tswv lag luam los thov tsawg kawg yog ob lub tsho tiv no ntawm cov xim zinc {0} galvanizing tshuaj txau) rau txhua daim teb- luas lossis drilled chaw.
Qhia tshwj xeeb tag nrho cov kev txiav, qhov, thiab kev hloov kho rau kev tsim kho kom raug rau kev kho mob corrosion thaum lub sijhawm kuaj xyuas zoo thaum zoo.
Yuam Kev 4: Siv cov neeg ceev ceev thiab cov fittings
Qhov tseem ceeb:
Cov khoom siv tsis zoo:Siv cov thawv hlau bolts rau ntawm cov hlau nplaum lub tais nplaum yuav ua rau cov galvanic corrosion.
Tsis muaj zog:Siv cov qauv -}}}}- Lub zog} Lub zog tau ua rau muaj kev cuam tshuam cov qauv kev sib raug zoo ntawm kev sib txuas.
Kev tiv thaiv:
Yuam kev uas txhua daim hlau splice, bolts, neeg rau, thiab fittings yuav tsum tau muab los ntawm cov khoom siv tais qub lossis qib ua cov tais nws tus kheej.
Txheeb xyuas cov ntaub ntawv pov thawj cov ntaub ntawv rau cov fasteners thiab cov khoom siv hluav taws xob thaum lub sij hawm tau txais kev kuaj xyuas.
Yuam kev 5: disorganized thiab interttwined cable pw
Qhov tseem ceeb:
Kev cuam tshuam ntawm kev cuam tshuam rau (crosstalk) tshwm sim thaum lub hwj chim thiab cov ntaub ntawv xov xwm khiav mus ze, sib npaug sib thooj.
Cov cua sov tsis zoo dissipation txo cov ampacity (tam sim no - nqa muaj peev xwm) ntawm lub peev xwm nqa tau.
Yav tom ntej txij nkawm, tshem tawm, lossis kev sib ntxiv ntawm cov kab ke tau nyuaj heev.
Kev tiv thaiv:
Tsim cov kev npaj meej rau kev teeb tsa ua ntej kev teeb tsa teeb tsa.
Siv cable cleats rau bundling fais fab ua kom zoo thiab cable sib zog tswj cov cables hauv txheej lossis pawg pawg.
Siv lub ntsej muag "hauv qab {-} {-}}}} Kev sim ua kom muaj kev txhim kho thoob plaws hauv kev khiav.
