Kev xaim hluav taws xob hauv tsev yog qhov tseem ceeb zais qhov project hauv tsev kho dua tshiab, thiab kev xaiv kom raug ntawm cov kab lus tshwj xeeb ncaj qha txiav txim siab hauv tsev neeg hluav taws xob kev nyab xeeb, khoom siv ua haujlwm ruaj khov, thiab kev pab cuam lub neej ntawm hluav taws xob circuits. Siv cov xov hlau uas nyias dhau tuaj yeem ua rau muaj hluav taws xob ntau dhau, overheating, tripping, lossis hluav taws kub; conversely, siv cov xov hlau tuab heev ua rau cov khoom siv thiab cov nqi pov tseg.
Lub hauv paus ntsiab lus tseem ceeb rau kev xaiv nyob hauv Cable
Tsis muaj qhov yuav tsum tau ua qhov muag tsis pom kev loj dua cov ntsuas hluav taws xob thaum xaiv cov cables rau tsev. Hloov chaw, kev txiav txim siab yuav tsum tau ua raws li plaub yam tseem ceeb: kev nyab xeeb, kev ua raws, kev ua tau zoo, thiab kev lag luam.
1. Cov ntsiab lus tseem ceeb ntawm cov khoom siv: Siv tsuas yog lub teb chaws tus qauv tooj liab ntshiab - cov tub ntxhais cables rau kev xaim hauv tsev. Aluminium-core lossis tooj liab-clad aluminium cables raug txwv nruj heev. Copper conductors muaj kev ruaj ntseg conductivity, siab -kub tsis kam, oxidation tsis kam, thiab txaus tam sim no - nqa peev xwm, ua rau lawv zoo tagnrho rau ntev - tsev neeg siv. Rau cov xaim hluav taws xob nyob hauv cov tsev siab- nce siab, qis- pa taws, qis- nplaim hluav taws kub toxicity- cov kab hluav taws xob tau pom zoo los txhim kho kev nyab xeeb hluav taws.
2. Fais fab sib piv txoj cai: Hlau gauge yuav tsum tau txiav txim los ntawm tag nrho cov hwj huam load ntawm txhua tus ib tug Circuit Court. High- cov khoom siv hluav taws xob yuav tsum tau ua ke nrog cov kab hluav taws xob tsim nyog, tshem tawm cov kev coj ua tsis zoo ntawm kev siv cov xov hlau tsis zoo rau siab - daim ntawv thov load.
3. Independent Circuit Principple: High-cov khoom siv hluav taws xob xws li cua txias, lub rhaub dej, thiab cov khoom siv hauv chav ua noj yuav tsum muaj cov khoom siv hluav taws xob thiab cov hluav taws xob sib cais. Nws yog txwv tsis pub sib koom circuits ntawm ntau lub siab -cov khoom siv hluav taws xob los tiv thaiv Circuit Court overload, kev laus ntxov ntxov, thiab nquag mus.
4. Reserve Capacity Principple: Nco ntsoov khaws 20% -30% muaj peev xwm ntxiv thaum lub sij hawm xaim kom haum rau yav tom ntej ntxiv cov khoom siv lossis cov khoom siv kho dua tshiab, zam qhov kev xav tau rov ua dua tom qab.
Hom Kev Siv Hluav Taws Xob Hluav Taws Xob thiab lawv cov ntawv thov
Tus qauv tooj liab- cov tub ntxhais cables siv hauv tsev xaim hluav taws xob poob rau hauv peb pawg tseem ceeb, txhua qhov tsim nyog rau kev teeb tsa sib txawv, ua kom pom tseeb thiab ncaj qha xaiv:
- BV Ib Leeg-Core Rigid Copper Wire: Insulated, corrosion-resistant, thiab zoo li qub, qhov no yog qhov kev xaiv tseem ceeb rau kev zais phab ntsa. Qhov zoo tshaj plaws rau tag nrho - cov xaim hauv tsev.
- BVR Multi-strand Flexible Copper Wire: Muab cov kev hloov pauv tau zoo thiab ua haujlwm rau kinking lossis tawg. Haum rau kev sib txuas ntawm lub davhlau ya nyob twg ntawm cov khoom siv kawg thiab qhov chaw nruj. tuaj yeem hloov BV xaim hauv kev zais zais, txawm tias kim dua me ntsis.
- YJV Hla- txuas Polyethylene Cable: Thaum tshav kub kub-resistant, siab-resistant, thiab nrog superior rwb thaiv tsev zog. Feem ntau siv rau cov kab nkag thiab hauv pem teb - theem kab hluav taws xob, tuav tag nrho cov khoom hluav taws xob ntawm tag nrho qhov chaw nyob.
Standard Tam sim no-Kev Muaj Peev Xwm Ntawm Cov Cables Loj thiab Tag Nrho-Cov Lus Qhia Hauv Tsev Zoning
Tus qauv hluav taws xob hauv tsev yog 220V, thiab cov ntsuas hluav taws xob sib txawv sib haum rau qhov ruaj ntseg tam sim no - nqa lub peev xwm thiab txwv kev thauj khoom. Hauv qab no yog ib daim ntawv qhia kev xaiv zoning uas siv tau thoob plaws cov tsev.
1. 5mm² Copper Cable
Kev nyab xeeb tam sim no - nqa peev: 10–12A
Haum rau kev thauj khoom mus txog 2,000W
Muab rau cov teeb pom kev zoo thoob plaws hauv lub tsev, sib haum nrog txhua hom teeb pom kev hauv tsev. Hauv cov xwm txheej txheem, 1.5mm² cables ua tau raws li lub teb chaws tus qauv. Tsuas yog nyob rau hauv loj - daim ntawv thov teeb pom kev zoo (piv txwv li, dav dav ambient teeb pom kev zoo) nws yuav tsum tau hloov mus rau 2.5mm², ua ke nrog 10A lossis 16A Circuit Court breaker.
2. 2.5mm² Copper Cable
Kev nyab xeeb tam sim no - nqa peev: 16-20A
Haum rau kev thauj khoom mus txog 4,000W
Tsim tshwj xeeb rau - lub hom phiaj lub qhov hluav taws xob. Zoo tagnrho rau chav nyob, chav pw, thiab chav noj mov, txhawb cov khoom siv xws li TVs, khoos phis tawj, thiab cov khoom siv me me. Ib lub voj voog ib zaug yuav tsum tsis pub tshaj 10 qhov hluav taws xob thiab yuav tsum tau tiv thaiv los ntawm 20A Circuit Court breaker.
3. 4mm² Copper Cable
Kev nyab xeeb tam sim no - nqa peev: 25-32A
Haum rau kev thauj khoom mus txog 5,500W
Npaj rau nruab nrab - mus rau siab - cov khoom siv fais fab. Pom zoo rau chav ua noj circuits, cia- hom hluav taws xob rhaub dej kub, 1–1.5 horsepower phab ntsa- mounted cua txias, microwaves, thiab lwm yam. Kitchen circuits yuav tsum tau ntsia nws tus kheej thiab tsis sib koom nrog dav - lub hom phiaj qhov hluav taws xob. Yuav tsum tau ua ke nrog 25-32A Circuit Court breaker.
4. 6mm² Copper Cable
Kev nyab xeeb tam sim no muaj peev xwm ntawm 32-40A, haum rau kev thauj khoom mus txog 7000W, sib haum nrog siab- cov khoom siv hluav taws xob thoob plaws hauv tsev, suav nrog 2-3 horsepower cua txias, hauv nruab nrab cua txias, instant dej rhaub, ua- hauv cov khoom siv hauv chav ua noj, thiab cov qhov cub hluav taws xob siab. Tag nrho cov khoom siv hluav taws xob siab yuav tsum muaj kev sib koom ua ke thiab ua ke nrog 32-40A Circuit Court breakers.
5. 10mm² tooj liab- tub ntxhais cable
Muaj kev nyab xeeb tam sim no muaj peev xwm ntawm 45-60A, siv los ua cov khoom siv hluav taws xob tseem ceeb rau cov tsev nyob, nqa tag nrho cov khoom hluav taws xob ntawm tag nrho lub tsev. Txheem 10mm² YJV cable raug pom zoo rau cov tsev peb lossis plaub chav pw; Cov chav loj lossis chav nyob nrog cov chaw them nyiaj hauv tsev tuaj yeem hloov kho mus rau 16mm², nrog rau tag nrho tsev neeg lub zog hluav taws xob ntsuas ntawm 63A.
Key Wiring Details thiab Standards
1. Qhov nruab nrab, nyob, thiab hauv av hlau sib tw: Cov xov hlau nyob thiab nruab nrab hauv cov qauv hluav taws xob yuav tsum muaj tib qho kev sib tw - cheeb tsam. Rau cov kab hluav taws xob siv 2.5mm² lossis cov xaim me me, cov xaim hauv av yuav tsum tsis pub tsawg dua 2.5mm²; rau 4mm² thiab 6mm² circuits, hauv av hlau yuav tsum tsis pub tsawg tshaj 4mm². Kev txo qis hauv av hlau loj arbitrarily yog nruj me ntsis txwv tsis pub.
2. Thaum tshav kub kub dissipation yuav tsum tau thaum lub sij hawm installation: Thaum xaim los ntawm conduits nyob rau hauv cov phab ntsa, tag nrho cov ntoo khaub lig-sectional cheeb tsam ntawm cables yuav tsum tsis pub tshaj 40% ntawm cov conduit nyob rau hauv lub cheeb tsam los tiv thaiv overcrowding, tsis zoo cua sov dissipation, thiab txo tam sim no - nqa peev xwm. Rau cov kab hluav taws xob ntev tshaj 50 meters los yog ntsia rau hauv siab - qhov kub thiab txias, lub ntsuas hluav taws xob yuav tsum tau nce kom tsim nyog kom tsis txhob muaj teeb meem hluav taws xob poob thiab kub dhau.
3. Circuit Segmentation Standards: Teeb pom kev zoo, dav dav - lub hom phiaj qhov hluav taws xob, thiab siab - cov khoom siv hluav taws xob yuav tsum tau xaim ntawm cov hluav taws xob sib cais, kev ywj pheej los tiv thaiv kev cuam tshuam. High- cov khoom siv fais fab yuav tsum ua raws li "ib lub cuab yeej, ib lub voj voog" txoj cai kom txo qis kev pheej hmoo ntawm kev ua txhaum.
