Lub laj kab hluav taws xob yog cov kab uas muaj cov kab uas thaiv rau hauv ib lossis ntau qhov thaiv cov hnab riam. Nws lub hom phiaj yog ua kom muaj kev ntseeg tau thiab muaj kev nyab xeeb ntawm cov xaim hluav taws xob hauv kev tsim khoom thiab hauv lub neej txhua hnub. Muaj ntau lub hauv paus rau xav txog thaum xaiv txoj cai hluav taws xob cable los ntawm ntau yam khoom lag luam.
Cov Lus Qhia
Kauj ruam 1
Xaiv koj lub hwj chim cable raws li cov khoom neeg xyuas pib, uas tuaj yeem yog tooj liab lossis txhuas. Tooj liab muaj tus cwj pwm zoo thiab tsis tshua xeb tau rau xeb. Los ntawm kev nyab xeeb qhov hluav taws kub ntawm qhov pom, tooj liab cable tseem muaj peev xwm.
Kauj ruam 2
Xam tag nrho lub zog ntawm cov ntsaws rau ntawm cable. Txhawm rau ua qhov no, koj yuav tsum txiav txim siab lub zog ntawm txhua tus neeg tau txais kev pab ntawm cov khoom siv txuas, siv cov ntaub ntawv sau tseg hauv cov ntaub ntawv pov thawj cov cuab yeej ntawm cov cuab yeej no.
Kauj ruam 3
Xam cov kab kev hla ntu ntawm qhov chaw ntawm cov xov hlau (cov tub ntxhais) ntawm lub hwj chim cable raws li xam cov load load lub zog thiab lub zog tam sim no. Nws yooj yim los ua nws siv cov ntxhuav tshwj xeeb. Nco ntsoov tias ntawm tsawg amperage qhov tseem ceeb, qhov sib tshooj ntawm tus neeg xyuas pib tooj liab yuav tsum yog tsawg kawg 1 mm the, thiab txhuas ib qho - 2 mm².
Kauj ruam 4
Txhawm rau xaiv txoj cai hluav taws xob cable, koj yuav tsum ua kom pom daim ntawv lo ntawm nws ntawm ntau hom. Yog li, thawj tsab ntawv nyob hauv nws qhia qhov khoom siv tus neeg xyuas pib (piv txwv li, "A" - aluminium cable). Hauv kev kos cim ntawm lub tooj liab cable, tsab ntawv tsis yog muab tso rau.
Kauj ruam 5
Txheeb xyuas cov khoom rwb thaiv tsev los ntawm tsab ntawv thib ob hauv kab hluav taws xob kos. Nws tuaj yeem ua cov roj hmab (txhais los ntawm tsab ntawv "P"), polyvinyl chloride (txhais los ntawm "B"), polyethylene - "P". Yog hais tias lub cable npaj rau tso rau hauv cov kav dej, tsab ntawv "T" yog tam sim no nyob rau hauv cov cim, thiab "G" txhais tau hais tias lub cable muaj peev xwm hloov tau.
Kauj Ruam 6
Xaiv cov xaim nrog qhov yuav tsum tau rwb thaiv tsev nyob ntawm cov teeb meem tau teeb tsa. Yog li, yog tias nws yog qhov yuav tsum tau muab cov xov hluav taws xob tso rau hauv txoj hauj lwm ntsug, nws raug nquahu kom siv cov PVC rwb thaiv tsev (piv txwv, AVVG thiab VVG). Rau kev tso rau hauv qhov chaw sov qhov siab, ib txoj xov hlau nrog cov ntaub thaiv tshwj xeeb thiab txhuas ib rab phom yog qhov yuav tsum tau ua.
Kauj Ruam 7
Txheeb xyuas cov hluav taws xob hauv koj lub network (220 lossis 380 V) thiab siv pes tsawg ntu siv. Raws li qhov no, xaiv lub xaim xaim hluav taws xob raws li tus naj npawb ntawm cov neeg xyuas pib hauv nws. Yog li, rau qhov voltage ntawm 220 V thiab ib theem, ob lossis peb ntu yog qhov xav tau, rau qhov voltage ntawm 380 V thiab peb theem - peb lossis plaub. Tus naj npawb ntawm cov neeg xyuas pib thiab lawv cheeb tsam hla kev yuav tsum tau ntaus cim hauv kev ntaus cim. Yog li, piv txwv li, cov lej 3x1, 5 txhais tau hais tias lub cable yog peb-tub ntxhais, nrog ntu ntu ntawm txhua tus neeg xyuas pib ntawm 1.5 mm².
Kauj ruam 8
Xam cov kab uas yuav tsum tau ntev. Txhawm rau ua qhov no, koj yuav tsum paub qhov kev ncua deb ntawm qhov kis ntawm qhov khoom sib txuas mus rau qhov chaw ntawm kev teeb tsa ntawm cov neeg siv khoom. Laij tau qhov ntau npaum li cas ntawm cable yuav tsum "txiav" nws, uas yog, tso tawm los ntawm rwb thaiv tsev rau kev sib txuas, ntawm tus nqi ntawm 1 meter rau 1 tus neeg siv khoom. Ntxiv 8% rau cov txiaj ntsig ntawm txoj kev khoov, txij li lub xaim hluav taws xob yuav tsum tau pw tsis muaj nro. Nyob rau hauv txhua rooj plaub, nws yog qhov zoo dua yuav lub cable nrog cov npoo, thiaj li tsis tsim nws tom qab.
