Xaiv Phau Ntawv Qhia
- Load tam sim no: Xaiv qhov loj me ntawm tus neeg xyuas pib siv tus qauv tsim tam sim no, tiv thaiv- ntaus ntawv ntsuas thiab siv tau lub rooj teeb tsa ampacity.
- Txoj kev txhim kho: Siv cov txheej txheem derating kom raug rau cov tais, cov kav dej, cov kav dej, faus, pawg lossis cov txheej txheem thermally insulated.
- Voltage poob: Txheeb xyuas qhov ntev ntawm lub voj voog, pib tam sim no thiab tso cai qhov hluav taws xob poob. Kev khiav mus ntev yuav xav tau tus neeg xyuas pib loj dua li ampacity ib leeg.
- Luv-circuit withstand: Txheeb xyuas tus neeg xyuas pib thermal tiv thaiv qhov kev ua txhaum tam sim no thiab tiv thaiv- lub sijhawm tshem tawm cov khoom siv.
- Ib leeg -core AC kev npaj: Nruab peb-theem conductors nyob rau hauv ib tug sib npaug tiaj tiaj los yog trefoil tsim thiab ua kom cov theem ntev thiab routing tej yam kev mob.
- Mechanical exposure: YJV yog unarmoured. Siv cov kav dej, duct, cable tais npog los yog lwm txoj kev tiv thaiv uas muaj kev cuam tshuam, crushing los yog siab rub quab yuam.
- Cov kev xav tau hluav taws kub: Txheem PVC sheath tsis yog qhov tsawg - pa taws xoom - halogen siv. Xaiv cov nplaim taws tshwj xeeb-retardant lossis LSZH cable qhov twg qhov project xav tau nws.
Cov lus nug nquag
YJV txhais li cas?
YJV txheeb xyuas cov tooj liab- tus neeg xyuas pib fais fab cable nrog XLPE rwb thaiv tsev thiab PVC txheej txheej. Nplooj ntawv no tsuas yog siv rau qhov tsis muaj armoured nkaus xwb -core 0.6/1 kV kev tsim kho.
YJV cable puas tuaj yeem faus ncaj qha?
Cov kab hluav taws xob tuaj yeem siv rau hauv kev tiv thaiv hauv av hauv qhov chaw uas txoj kev tsis tuaj yeem ua rau puas tsuaj rau lub zog. Cov kav dej, npog lossis lwm yam khoom siv- txoj kev tiv thaiv yog qhov tsim nyog vim tias tus qauv YJV tsis muaj armoured.
Ib -core YJV cable siv tau rau peb-theem AC fais fab?
Yog lawm. Ib lub cable yog siv rau txhua theem, nrog nruab nrab thiab tiv thaiv conductors ntxiv raws li qhov xav tau. Theem conductors yuav tsum tau teem nyob rau hauv ib tug sib xws trefoil los yog tiaj tus tsim.
Vim li cas cov hlau nplaum yuav tsum zam ib ncig ntawm ib qho -core AC cable?
Hloov tam sim no tsim ib qho kev hloov magnetic teb. Lub voj kaw ferrous nyob ib ncig ntawm ib tus neeg xyuas pib tuaj yeem txhim kho eddy-tam sim no thiab hysteresis poob, ua rau muaj cua sov hauv zos txaus ntshai.
YJV puas yog qis- pa taws xoom-halogen cable?
Tsis yog. Standard YJV siv PVC sheath. Cov haujlwm uas xav tau cov pa luam yeeb tsawg thiab halogen- kev ua haujlwm pub dawb xav tau kev tsim kho LSZH cable tshwj xeeb.
Yuav ua li cas xaiv tus neeg xyuas pib qhov loj?
Siv cov qauv tsim tam sim no, kev txhim kho ampacity, pab pawg thiab qhov kub thiab txias derating, voltage poob, luv luv -circuit tiv taus thiab txiav kev txwv. Cable hnyav los yog sab nraud txoj kab uas hla yuav tsum tsis txhob siv los xaiv hluav taws xob muaj peev xwm.
Puas yog cov npe teev muaj tseeb?
Lawv yog cov khoom siv nominal. Qhov kawg qhov ntev thiab qhov hnyav tuaj yeem sib txawv hauv kev tsim kev kam rau siab thiab nrog kev xaiv tus neeg xyuas pib.
