1. Scope ntawm daim ntawv thov: Nws yog qhov tsim nyog rau kev sib txuas ntawm cov khoom siv nruab nrab thiab lub teeb txawb (cov khoom siv hauv tsev, cov cuab yeej hluav taws xob, thiab lwm yam), cov cuab yeej siv, thiab lub teeb pom kev zoo; Qhov ua haujlwm voltage yog AC 750V thiab qis dua, thiab feem ntau yog AC 300C.
2. Vim tias cov khoom yuav tsum tau txav mus los, khoov, twisted ntau zaus, thiab lwm yam, cov hlua fais fab yuav tsum yog mos, ruaj khov hauv cov qauv, tsis yooj yim rau kink, thiab muaj qee yam hnav tsis kam; cov yas sheathed roj hmab fais fab qaum tuaj yeem tso ncaj qha rau hauv av.
3. Cov xaim hauv av txais cov xaim daj-ntsuab ob-xim xaim, thiab lwm cov hlau cores hauv cov roj hmab fais fab qaum tsis raug tso cai siv cov hlau daj-ntsuab.
4. Thaum siv rau txoj kab txuas hluav taws xob ntawm cov khoom siv hluav taws xob cua sov, braided roj hmab insulated cords lossis roj hmab insulated cords yuav tsum tau siv raws li qhov tsim nyog.
5. Cov qauv yuav tsum ua kom yooj yim thiab lub teeb.
6. Qauv
1) Conductive fais fab core: Nws txais cov tub ntxhais tooj liab, cov qauv hloov tau yooj yim, thiab nws yog twisted los ntawm ntau cov hlua ib leeg; tus neeg xyuas pib hloov tau yooj yim feem ntau siv 5th lossis 6th hom conductor qauv.
2) Rwb thaiv tsev: Cov khoom siv insulating feem ntau yog ua los ntawm ntuj styrene-butadiene roj hmab, polyvinyl chloride lossis mos polyethylene yas.
3) Lub cable suab ntau yog me me.
4) Cov txheej tiv thaiv txheej yog woven nrog paj rwb xov kom tsis txhob overheating thiab scalding lub insulating txheej.
5) Txhawm rau kom yooj yim rau kev siv thiab ua kom yooj yim rau cov txheej txheem tsim khoom, cov qauv peb-core tshuav nyiaj li cas tau txais, uas tuaj yeem txuag lub sijhawm ntau lawm thiab txhim kho kev tsim khoom.
