Hauv cov chaw uas muaj cov pa roj uas kub hnyiab thiab tawg, yuav tsum siv cov xov hlau uas muaj cov hlau rwb thaiv tsev thiab muab tso rau ntawm lawv tus kheej. Cov ntsia hlau rau kev txhim kho cov kab faib khoom thiab cov khoom siv yuav tsum tsis txhob vuam rau ntawm cov qauv hlau hauv tsev. Cov kab txuas av (PE) lossis cov kab txuas xoom (PEN) ntawm cov kab faib khoom hauv tsev yuav tsum tau txuas nrog cov kab sib txuas sib xws thiab yuav tsum tsis txhob txuas ua ke.
Cov kav dej hlau lossis cov ntoo uas muaj xov hlau yuav tsum tsis txhob vuam nrog cov xov hlau jumper ground, thiab yuav tsum tau jumper nrog cov chaw grounding tshwj xeeb. Yuav tsum ntxiv cov hlau casings qhov twg cov xov hlau grounding hla lub tsev thiab hauv pem teb, thiab cov casings yuav tsum tau grounded. Thaum cov xov hlau grounding hla lub deformation sib koom ua ke ntawm lub tsev, yuav tsum tau ua cov kev ntsuas them rov qab.
Qhov kev ncua deb ntawm cov chaw faib hluav taws xob hauv qab 100A siv hauv chav huv thiab cov khoom siv yuav tsum tsis pub tsawg dua 0.6m, thiab yuav tsum tsis pub tsawg dua 1m thaum nws ntau dua 100A. Lub switchboard, vaj huam sib luag tswj hwm, thiab lub thawv hloov pauv ntawm chav huv yuav tsum tau teeb tsa rau hauv. Qhov sib txawv ntawm lawv thiab phab ntsa yuav tsum ua los ntawm cov qauv roj thiab yuav tsum sib haum nrog kev kho kom zoo nkauj ntawm lub tsev. Lub qhov rooj nkag ntawm cov switchboards thiab cov txee tswj hwm yuav tsum tsis txhob qhib hauv chav huv. Yog tias lawv yuav tsum nyob hauv chav huv, qhov rooj kaw yuav tsum tau teeb tsa rau ntawm cov vaj huam sib luag thiab cov txee. Cov nplaim sab hauv thiab sab nraud ntawm cov txee tswj hwm yuav tsum du, tsis muaj plua plav, thiab yooj yim ntxuav. Yog tias muaj qhov rooj, qhov rooj yuav tsum kaw kom nruj.
Yuav tsum tau teeb tsa cov teeb rau chav huv rau saum qab nthab. Thaum teeb tsa lub qab nthab, txhua qhov uas hla dhau lub qab nthab yuav tsum tau kaw nrog cov sealant, thiab cov qauv ntawm qhov yuav tsum kov yeej qhov cuam tshuam ntawm cov sealant shrinkage. Thaum teeb tsa recessed, lub teeb yuav tsum tau kaw thiab cais tawm ntawm qhov chaw tsis huv. Yuav tsum tsis muaj bolts lossis screws hla dhau hauv qab ntawm unidirectional flow static plenum.
Cov khoom siv hluav taws kub, cov khoom siv cua txias uas rhiab heev rau qhov kub thiab av noo thiab lwm yam khoom siv hluav taws xob uas tau teeb tsa hauv chav huv yuav tsum huv thiab tsis muaj plua plav ua ntej lub tshuab cua txias huv tau pib siv. Cov khoom no yog siv rau hauv ib puag ncig uas xav tau kev ntxuav lossis tua kab mob ntau zaus nrog dej. Lub cuab yeej yuav tsum siv cov txheej txheem tiv thaiv dej thiab tiv thaiv xeb.
