1. Txheeb xyuas "CCC" daim ntawv pov thawj
Cov khoom siv fais fab cable yog cov khoom siv tau ntawv pov thawj. Txhua lub tuam txhab yuav tsum tau txais daim ntawv pov thawj "CCC" los ntawm Tuam Tshoj Electrotechnical Product Certification Commission, thiab muaj "CCC" daim ntawv pov thawj ntawm daim ntawv pov thawj lossis cov khoom lag luam.
2. Tshawb xyuas daim ntawv tshuaj ntsuam xyuas
Raws li cov khoom lag luam cuam tshuam rau tib neeg thiab cov khoom ntiag tug, cov khoom siv hluav taws xob ib txwm tau teev tseg raws li qhov tseem ceeb ntawm tsoomfwv saib xyuas thiab tshuaj xyuas, thiab cov tuam txhab lag luam tsis tu ncua yuav raug tshuaj xyuas raws sijhawm los ntawm lub tuam tsev saib xyuas. Yog li ntawd, tus neeg muag khoom yuav tsum muaj peev xwm muab cov ntaub ntawv soj ntsuam ntawm lub chaw soj ntsuam zoo, txwv tsis pub, qhov zoo ntawm cov khoom siv fais fab cable yuav tsis muaj lub hauv paus.
3. Saib ntawm pob
Cov chaw lag luam niaj hnub uas tsim cov khoom lag luam uas ua tau raws li cov qauv siv tau zoo heev rau cov khoom ntim cov khoom siv hluav taws xob. Thaum yuav khoom, xyuam xim rau cov ntim khoom zoo, luam ntawv ntshiab, ua tiav cov qauv, specifications, lub Hoobkas lub npe thiab chaw nyob.
4. Saib koj lub ntsej muag
Cov tsos ntawm cov khoom yog du thiab puag ncig, thiab xim yog txawm. Rau cov tuam txhab fais fab cable uas nws cov khoom ua tau raws li tus qauv yuav tsum tau ua, txhawm rau txhim kho cov khoom zoo thiab xyuas kom meej tias cov khoom ua tau raws li tus qauv, lawv nruj me ntsis tswj kev yuav khoom ntawm raw khoom, cov khoom siv, cov txheej txheem ntau lawm, thiab lwm yam. cov khoom siv fais fab cable ua tau raws li tus qauv yuav tsum tau ua, uas yog du, puag ncig thiab txawm nyob hauv xim. Cov tsos ntawm cov khoom cuav thiab cov khoom tsis zoo yog ntxhib thiab lusterless. Rau cov roj hmab insulated saj zawg zog cables, cov tsos yuav tsum yog puag ncig, thiab cov ntaub qhwv, rwb thaiv tsev thiab tus neeg xyuas pib yuav tsum nruj thiab tsis yooj yim rau tev tawm. Cov khoom cuav thiab shoddy muaj cov tsos ntxhib, loj ovality thiab tsis muaj zog rwb thaiv tsev, uas tuaj yeem torn los ntawm tes.
5. Saib ntawm tus neeg xyuas pib
Tus neeg xyuas pib yog glossy, thiab DC tsis kam thiab tus neeg xyuas pib loj raws li tus qauv yuav tsum tau ua. Cov khoom siv hlau thiab cable uas ua tau raws li tus qauv yuav tsum tau ua, txawm tias txhuas lossis tooj liab conductors, yog ci thiab tsis muaj roj, yog li tus neeg xyuas pib DC tam sim no.
