1. Taw qhia
Xaiv qhov chaw hla txoj cai rau lub vuam cable yog qhov tseem ceeb tshaj qhov koj xav. Nws cuam tshuam ncaj qha rau kev ua haujlwm ntawm koj lub tshuab vuam thiab ua kom muaj kev nyab xeeb thaum ua haujlwm. Ob yam tseem ceeb uas yuav tsum nco ntsoov thaum koj xaiv yog tus nqi tam sim no ntawm lub cable tuaj yeem tuav thiab qhov hluav taws xob poob ntawm nws qhov ntev. Tsis quav ntsej txog cov xwm txheej no tuaj yeem ua rau muaj cua sov, ua haujlwm tsis zoo, lossis txawm tias cov cuab yeej puas tsuaj loj.
Cia peb rhuav tshem yam koj yuav tsum paub hauv txoj kev yooj yim, ib kauj ruam dhau-kauj ruam.
2. Yam tseem ceeb uas yuav tau xav txog
Thaum xaiv ib lub welding cable, muaj ob qho kev txiav txim siab tseem ceeb:
- Tam sim no muaj peev xwm:
- Qhov no yog hais txog ntau npaum li cas tam sim no lub cable tuaj yeem nqa tau yam tsis muaj cua sov. Qhov luaj li cas ntawm cov kab hluav taws xob (qhov chaw hla ntu) txiav txim siab nws qhov ampacity.
- Rau cov cables luv dua 20 meters, feem ntau koj tuaj yeem tsom mus rau qhov ampacity ib leeg, vim tias qhov hluav taws xob poob yuav tsis tseem ceeb.
- Cov cables ntev dua, txawm li cas los xij, yuav tsum tau ua tib zoo saib xyuas vim tias qhov kev tiv thaiv ntawm cov kab hluav taws xob tuaj yeem ua rau poob rau hauv qhov hluav taws xob, uas cuam tshuam rau kev ua haujlwm ntawm koj lub vuam.
- Voltage poob:
- Qhov hluav taws xob poob ua ib qho tseem ceeb thaum lub cable ntev tshaj 20 meters. Yog hais tias lub cable nyias dhau rau qhov tam sim no nws nqa, qhov hluav taws xob poob nce, txo lub zog xa mus rau lub tshuab vuam.
- Raws li txoj cai ntawm tus ntiv tes xoo, qhov poob qis yuav tsum tsis pub tshaj 4V. Tshaj li 50 meters, koj yuav tsum tau kho cov kev suav thiab tejzaum nws yuav xaiv ib tug tuab cable kom tau raws li qhov yuav tsum tau.
3. Xam qhov Hla-Section
Cia peb saib ib qho piv txwv kom pom tias qhov no ua haujlwm li cas:
- Piv txwv tias koj qhov vuam tam sim no300 A, thiab lub sijhawm thauj khoom (ntau npaum li cas lub tshuab ua haujlwm) yog60%. Cov txiaj ntsig tam sim no suav nrog:
300A × 60% = 234A
- Yog tias koj tab tom ua haujlwm nrog qhov ceev tam sim no7A/mm², koj yuav xav tau ib tug cable nrog ib tug ntoo khaub lig-sectional cheeb tsam ntawm:
234A÷7A/mm2 = 33.4mm2
- Raws li qhov tshwm sim no, qhov kev sib tw zoo tshaj plaws yuav yog aYHH-35 roj hmab hloov tau cable, uas muaj thaj tsam ntawm 35mm².
Cov kab no yuav ua haujlwm tam sim no yam tsis muaj cua sov thiab ua haujlwm tau zoo tshaj qhov ntev txog li 20 meters.
4. Txheej txheem cej luam ntawm YHH Vuam Cable
YHH cable yog dab tsi?YHH welding cables yog tsim tshwj xeeb rau kev sib txuas ntawm ob sab hauv vuam tshuab. Cov cables no yog tawv, hloov tau, thiab zoo haum rau qhov hnyav ntawm vuam.
- Voltage Compatibility: Lawv tuaj yeem tswj AC qhov siab tshaj qhov hluav taws xob mus txog200 Vthiab DC peak voltages mus txog400 V.
- Ua haujlwm kub: Qhov siab tshaj plaws ua haujlwm kub yog60 ° C, kom ntseeg tau tias kev ua tau zoo txawm tias nyob rau hauv kev siv tas li.
Vim li cas YHH cables?Cov qauv tshwj xeeb ntawm YHH cables ua rau lawv yoog raws, yooj yim los tuav, thiab tiv taus hnav thiab tsim kua muag. Cov khoom no yog qhov tseem ceeb rau kev siv vuam uas nquag txav thiab qhov chaw nruj heev.
5. Cable Specification Table
Hauv qab no yog cov lus qhia tshwj xeeb rau YHH cables. Nws qhia txog cov ntsiab lus tseem ceeb, suav nrog cable loj, qhov sib npaug ntawm qhov chaw sib npaug, thiab tus neeg xyuas pib ua haujlwm.
Cable Size (AWG) | Qhov Loj (mm²) | Ib Core Cable Loj (mm) | Sheath Thickness (hli) | Txoj kab uas hla (mm) | Conductor Resistance (Ω/km) |
---|---|---|---|---|---|
7 | 10 | 322/0.20 Nws | 1.8 | 7.5 | 9.7 ib |
5 | 16 | 513/0.20 Nws | 2.0 | 9.2 ib | 11.5 |
3 | 25 | 798/0.20 Nws | 2.0 | 10.5 | 13 |

Lub rooj no qhia li cas rau peb?
- AWG (American Wire Gauge): Cov lej me me txhais tau tias cov xov hlau tuab dua.
- Sib npaug: Qhia qhov chaw seem hauv mm².
- Tus neeg xyuas pib Resistance: Tsawg kuj txhais tau hais tias tsawg dua voltage poob.
6. Cov lus qhia siv rau kev xaiv
Nov yog daim ntawv teev npe ceev los pab koj xaiv txoj cai cable:
- Ntsuas qhov ntev ntawm koj cov welding cable.
- Txiav txim siab qhov siab tshaj plaws tam sim no koj lub tshuab vuam yuav siv.
- Xav txog lub sijhawm thauj khoom ntev npaum li cas (lub tshuab siv ntau npaum li cas).
- Xyuas qhov hluav taws xob poob rau cov cables ntev dua (tshaj 20m lossis 50m).
- Siv cov lus qhia tshwj xeeb los nrhiav qhov zoo tshaj plaws match raws li tam sim no ceev thiab loj.
Yog tias tsis ntseeg, nws ib txwm muaj kev nyab xeeb dua mus nrog ib lub xov tooj me me. Ib lub cable tuab yuav raug nqi ntau dua, tab sis nws yuav muab kev ua haujlwm zoo dua thiab kav ntev dua.
7. Cov lus xaus
Xaiv qhov raug vuam cable yog txhua yam hais txog kev ntsuas qhov muaj peev xwm tam sim no thiab qhov hluav taws xob poob thaum khaws kev nyab xeeb thiab ua haujlwm hauv siab. Txawm hais tias koj siv 10mm² cable rau kev ua haujlwm sib zog lossis 95mm² cable rau kev siv hnyav, nco ntsoov ua kom phim cov cable rau koj cov kev xav tau tshwj xeeb. Thiab tsis txhob hnov qab mus sab laj cov lus qhia tshwj xeeb rau kev taw qhia meej.
