Cov yam ntxwv kub ntawm cov hluav taws xob cable sib txawv nyob ntawm seb hom cable thiab cov khoom siv rwb thaiv tsev, npog cov hauv qab no:
Rated Ua Haujlwm Kub:
- Txheem XLPE- insulated cables: 90 degree
- PVC- insulated cables: 70 degree
- Fluoroplastic-insulated, silicone roj hmab- sheathed cables: 180 degree
- Fluoroplastic- insulated thiab sheathed cables: 200 degree
- CE low{0}}kub fais fab cables: 120 degree
Luv -Circuit Temperature:
- Rau feem ntau cov fais fab cables, tus neeg xyuas pib kub thaum lub sij hawm luv luv Circuit Court (ntev tsis tshaj 5 vib nas this) tsis tshaj 250 degree
- Rau qee cov cables tshwj xeeb, xws li nplaim hluav taws- cov hluav taws xob hluav taws xob, qhov luv - qhov kub ntawm qhov hluav taws xob yog 160 degree
Installation Kub:
- Feem ntau, qhov kub thiab txias thaum lub sijhawm teeb tsa cable yuav tsum tsis txhob qis dua 0 degree
- High -cov kab hluav taws xob tiv taus kub tuaj yeem ntsia tau ntawm qhov kub thiab txias li -15 degree
- Tshwj xeeb qis-kub fais fab cables tuaj yeem siv rau hauv qhov chaw txias li -60 degree
Kev laus yam ntxwv:
- Cable lifespan yog cuam tshuam los ntawm qhov kub thiab txias thiab ua raws li Arrhenius nkhaus
- Kev ntsuas lub neej ntawm PVC cables yog kwv yees li 20 xyoo
- Qhov kub thiab txias ua kom cov kab laus laus thiab txo cov kev pab cuam lub neej
Ambient Temperature Effects:
- Tam sim no - nqa lub peev xwm yuav tsum tau hloov kho los ntawm kev kho cov xwm txheej raws li qhov kub thiab txias
- Rau kev teeb tsa hauv huab cua, qhov kho kom raug yog 1.00 ntawm qhov ntsuas kub ntawm 40 degree
- Rau kev faus ncaj qha, qhov kho kom raug yog 1.00 ntawm av kub ntawm 25 degree
Emergency Load Yam ntxwv:
- Cov kab hluav taws xob tuaj yeem tiv taus qhov xwm txheej ceev tshaj qhov ntsuas kub rau lub sijhawm luv
- Cov kev cai tiv thaiv overload txawv ntawm cov qauv (ANSI/IEEE vs. CENELEC/IEC)
Bending Radius Requirements:
- Ib leeg -cov tub ntxhais cables: Feem ntau 15–20 npaug ntawm cov kab hluav taws xob sab nraud
- Multi-cov tub ntxhais cables: Feem ntau 10–15 npaug ntawm cov kab hluav taws xob sab nraud
