Anelectrical conduitis lub raj siv los tiv thaiv thiab txoj kab hluav taws xob thaiv lub tsev lossis cov qauv. Hluav taws xob hluav taws xob tuaj yeem ua cov hlau, yas, fiber ntau, orfired av nplaum. Yuav luag txhua qhov kev sib cav sib ceg sib zog, tab sis yoog tau siv rau qee yam.
Conduit feem ntau nruab los ntawm xaiv qhov chaw ntawm kev teeb tsa ntawm cov khoom siv hluav taws xob. Nws siv, daim ntawv, thiab cov ntsiab lus qhia txog kev teeb tsa feem ntau tau hais tseg los ntawm cov kev cai xov hluav taws xob, xws li USNational Hluav Taws Xob (NEC) thiab lwm cov kev cai tsim.
Cov hluav taws xob hluav taws xob tiv thaiv tau zoo tiv thaiv rau cov neeg ua hauj lwm ntawm kev cuam tshuam los ntawm kev cuam tshuam, ya raws, thiab vapors tshuaj. Hloov cov lej, qhov ntau thiab tsawg thiab hom ntawm tus neeg xyuas pib yuav rub rau hauv ib qho kev sib nkag siab, uas yooj yim tsim qauv thiab kev tsim kho piv rau ntau qhov sib txawv ntawm cov xaim hluav taws xob lossis cov nuj nqis ntawm cov kev sib koom ua ke cable. Cov xaim hluav taws xob hauv cov tsev yuav raug rau kev hloov mus los ntau zaus. Cov kev hloov pauv ntawm cov hluav taws xob tau hloov tau yooj yim dua thiab muaj kev nyab xeeb dua los ntawm kev siv hluav taws xob, vim tias tus neeg xyuas pib tam sim no tuaj yeem raug rho tawm thiab cov thawj coj tshiab tau teeb tsa, nrog kev cuam tshuam me me ntawm txoj kev ntawm txoj kab ke.
Lub kaw lus xuas hluav taws xob tuaj yeem ua rau dej tsis ntub lossis tsis tuaj yeem. Kev siv hlau ua hluav taws xob tuaj yeem siv los tiv thaiv cov hluav taws xob tsis zoo ntawm cov khoom siv hluav taws xob, thiab tseem tuaj yeem tiv thaiv kom tsis txhob muaj kev cuam tshuam ntawm cov kev cuam tshuam zoo li no los ntawm lub zog hluav taws xob. Cov hlau tsis muaj kab uas tiv taus corrosion thiab yog lub teeb-hnyav, txo cov nqi nruab zog.
Thaum ntsia nrog cov fittings sealing tsim nyog, ib qho kev sib nkag siab yuav tsis tso cai rau qhov ntws tawm ntawm cov pa roj thiab vapors, uas muab kev tiv thaiv los ntawm cov hluav taws thiab tawg txaus ntshai nyob rau hauv cov chaw tuav cov tshuaj tsis haum.
Qee hom conduit raug pom zoo rau kev nkag ncaj qha rau hauv pob zeb. Qhov no nquag siv hauv cov tsev lag luam txhawm rau tso cai hluav taws xob thiab kev sib txuas lus tau nruab rau hauv nruab nrab ntawm qhov chaw qhib loj. Piv txwv li, khw muag khoom tawm rooj sib hais cov ntaub ntawv thiab cov chaw ua haujlwm siv cov thawv ntim hauv pem teb kom txuas tau lub zog thiab cov xaim hluav taws xob.
Ob qho tib si hlau thiab cov yas ua ke tuaj yeem khoov rau ntawm qhov chaw ua haujlwm kom tso cai rau lub chaw dai kom zoo uas tsis muaj ntau tus naj npawb ntawm cov fittings. Qhov no yog qhov tshwj xeeb tshaj yog thaum ua raws cov lus tsev tsis xwm yeem lossis nkhaus. Kev nthuav dav tshwj xeeb khoov dab tsi yog siv los khoov lub qhov txuas yam tsis muaj kinking lossis tsoo nws.
Tus nqi ntawm conduit installation yog siab dua lwm txoj hauv kev siv xov tooj vim yog tus nqi ntawm cov khoom siv thiab tus neeg ua haujlwm. Hauv cov ntawv thov xws li thaj chaw tsim kho, qib siab ntawm kev tiv thaiv kev tiv thaiv lub cev tej zaum yuav tsis xav tau, yog li cov nqi ntawm conduit tsis tuaj yeem lav. Cov kab hluav taws xob uas ntsia tau rau hauv cov hluav taws xob tsis tuaj yeem tiv thaiv cov cua sov tau yooj yim ib yam li cov teeb tsa hauv cov xov hluav taws xob qhib, yog li tam sim no cov khoom siv ntawm txhua tus neeg xyuas pib yuav tsum tau txo (derated) yog tias muaj ntau qhov nruab rau hauv ib qho txuas. Nws yog qhov tsis yooj yim, thiab txwv tsis pub ua los ntawm cov kev tswj kab hluav taws xob, kom muaj ntau dua 360 qib ntawm tag nrho cov khoov hauv kev khiav ntawm qhov sib dhos, yog li cov qhov hluav taws xob tshwj xeeb yuav tsum tau muab tso rau cov neeg tswj xyuas ntsia tsis muaj kev puas tsuaj nyob rau hauv cov kev khiav no.
Qee hom hlau txuas kuj tseem siv tau ua kev sib raug zoo ntawm tus coj rau grounding (earthing), tab sis cov cai tswj kav hluav taws xob kuj tseem yuav sau cov qauv kev ua haujlwm lossis cov kev cai ntxiv ntawm kev mus rau qee yam. Thaum hlau hlau txuas qee zaum siv los ua cov kav hluav taws xob puag ncig, qhov ntev ntawm txoj haujlwm Circuit Court yog qhov tsawg. Piv txwv li, lub sijhawm ntev ntawm kev sib tw raws li tus kav lub hauv av yuav muaj qhov siab dhau hluav taws xob tsis kam, thiab tsis tso cai rau kev ua haujlwm ntawm cov khoom siv hluav taws xob ntau dhau ntawm kev txhaum.
