Ifomula

Ifomula Yokubalwa Kwedatha

isigaba-isihloko
1 I-Enameled Copepr Wire- ifomula yokuguqula isisindo nobude L/KG L1=143M/(D*D )
2 Intambo Ewunxande- ifomula yokuguqula isisindo nobude g/L Z=(T*W-0.2146*T2)*8900*1000/1000000
3 Indawo ephambanayo ye-Rectangular Wire mm2 S=T*W-0.2146*T2
4 I-Litz Wire-weight nefomula yokuguqula ubude L/KG L2=274 / (D*D*2*Imigqa)
5 Ukumelana nocingo oluwunxande Ω/L R=r*L1/S
6 Ifomula 1:Ukumelana ne-Litz Wire Ω/L R20=Rt ×α×103/L3
7 Ifomula 2:Ukumelana ne-Litz Wire Ω/L R2(Ω/Km)≦ r×1.03 ÷s×at×1000
L1 Ubude(M) R1 Ukumelana(Ω/m)
L2 Ubude(M/KG) r 0.00000001724Ω*㎡/m
L3 Ubude(KM) R20 Ukumelana ne-conductor nge-1km ngayinye ku-20°C (Ω/km)
M Isisindo(KG) Rt Ukumelana ku-t°C (Ω)
D Ububanzi(mm) αt I-Temperature Coefficient
Z Isisindo(g/m) R2 Ukumelana(Ω/Km)
T Ubukhulu(mm) r Ukumelana nemitha eyi-1 yocingo lwethusi olunomucu owodwa
W Ububanzi(mm) s Imicu (ama-pcs)
S Indawo Ehlukene (mm2)
