Cov kauj ruam rau Kev Txhim Kho thiab Routing THHN Hlau
Kauj ruam 1: Nruab lub Conduit System
THHN hlau yuav tsum tau muab tso rau hauv cov kav dej rau kev tiv thaiv thiab ua raws li NEC cov qauv.
Nruab lub Conduit:
Siv cov khoom siv tsim nyog, xws li PVC rau kev teeb tsa sab nraum zoov lossis EMT rau kev siv sab hauv tsev.
Ruaj ntseg cov conduits rau phab ntsa, qab nthab, los yog pem teb siv mounting brackets.
Xyuas Fittings thiab Connectors:
Xyuas kom tag nrho cov fittings yog nruj thiab kaw, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ntub.
Tshawb xyuas Txoj Kev Conduit:
Paub meej tias txoj kev no yog qhov tseeb ntawm cov khib nyiab lossis cov khoom thaiv.
Kauj Ruam 2: Rub lub THHN Hlau Los Ntawm Cov Conduit
Npaj Cov Hlau:
Txiav THHN xaim mus rau qhov ntev uas yuav tsum tau ua, tso cai ntxiv slack rau kev sib txuas.
Siv cov xov hlau sib txawv rau theem, nruab nrab, thiab hauv av sib txuas rau kev txheeb xyuas yooj yim.
Pub Cov Hlau:
Txuas lub THHN xaim rau ntses daim kab xev los yog lub tshuab rub tawm.
Lubricate cov xov hlau nrog lub xaim rub lub roj nplaum kom txo kev sib txhuam thaum lub sijhawm teeb tsa.
Rub Cov Hlau:
Maj mam rub cov ntses daim kab xev los ntawm cov kav dej, coj THHN hlau rau hauv qhov chaw.
Tsis txhob quab yuam ntau dhau los tiv thaiv kev puas tsuaj rau cov rwb thaiv tsev lossis nylon txheej.
Ruaj Ntseg Hlau:
Siv cov hlua khi los yog cov hlua khi los txhim kho thiab ruaj ntseg cov xov hlau hauv cov thawv sib txuas lossis cov khoom xa tawm.
Kauj Ruam 3: Ua Kev Sib Txuas
Tshem cov Hlau Xaus:
Siv cov hlau stripper tshem tawm cov nylon txheej thiab rwb thaiv tsev los ntawm qhov kawg ntawm THHN hlau, nthuav tawm cov neeg xyuas pib.
Txuas rau Terminals:
Ruaj ntseg lub stripped hlau xaus rau lub davhlau ya nyob twg blocks, keyboards, los yog receptacles siv screws los yog clamps.
Ua raws li cov kab kos duab rau kev sib txuas kom raug.
Sau cov kab:
Siv cov cuab yeej sau npe los txheeb xyuas txhua txoj haujlwm ntawm cov xaim (piv txwv li, theem, nruab nrab, hauv av).
Kev coj ua zoo tshaj plaws rau Routing THHN Hlau
1. Txo qhov khoov thiab lim
Tsis txhob muaj kev khoov ntse hauv cov kav dej kom tsis txhob muaj kev ntxhov siab ntawm THHN hlau.
Siv dav-radius khoov rau smoother routing.
2. Npog cov kab hlau tsim nyog
Thaum routing ntau cov xov hlau, khi lawv kom huv si kom tsis txhob tangling lossis neeg coob coob.
Cia qhov chaw txaus nyob rau hauv lub conduit kom tsis txhob overheating.
3. Tiv thaiv ib puag ncig yam
Siv cov kav dej kaw ntom nti thiab cov khoom siv tiv thaiv huab cua nyob rau sab nraum zoov lossis qhov chaw ntub dej.
Xyuas kom cov av tsim nyog txhawm rau txhim kho kev nyab xeeb thiab kev cia siab rau qhov system.
Kev kuaj thiab ua tiav kev teeb tsa
Ua Kev Ntsuas Hluav Taws Xob
Siv lub tshuab ntsuas ntau los ntsuas qhov txuas ntxiv, qhov hluav taws xob, thiab kev ua haujlwm ntawm THHN xaim.
Xyuas kom muaj av zoo thiab xyuas kom tsis muaj qhov luv luv.
Kev sib txuas ruaj ntseg
