chikamu-zita
1 Enameled Copepr Wire- uremu uye kureba kushandura fomula L/KG L1=143M/(D*D )
2 Rectangular Wire- uremu uye kureba kushandura formula g/L Z=(T*W-0.2146*T2)*8900*1000/1000000
3 Muchinjikwa-chikamu nzvimbo yeRectangular Wire mm2 S=T*W-0.2146*T2
4 Litz Wire-huremu uye kureba shanduko formula L/KG L2=274 / (D*D*2* Mitambo)
5 Kupokana kwerectangular wire Ω/L R=r*L1/S
6 Formula 1:Kupokana kweLitz Wire Ω/L R20=Rt ×α×103/L3
7 Formula 2:Kupokana kweLitz Wire Ω/L R2(Ω/Km)≦ r×1.03 ÷s×pa×1000
L1 Urefu(M) R1 Kuramba(Ω/m)
L2 Kureba(M/KG) r 0.00000001724Ω*㎡/m
L3 Urefu(KM) R20 Conductor kuramba pa 1km pa20°C (Ω/km)
M Huremu (KG) Rt Kuramba pa t°C (Ω)
D Dhayamita(mm) αt Temperature Coefficient
Z Huremu(g/m) R2 Kuramba(Ω/Km)
T Hukobvu(mm) r Kupokana kwe 1 mita imwe-strand enameled copper waya
W Upamhi(mm) s Strands (pcs)
S Muchinjikwa-chikamu (mm2)
