Wire and cable material consumption calculation formula

Information Source:Henan Huadong Cable Co., Ltd Release date:2014-05-16

1 conductor dosage: (Kg/Km) =d^2 * 0.7854 * G * N * K1 * K2 * C d= copper wire diameter G= copper proportion N= number K1= copper stranding ratio K2= cored wire stranding ratio C= insulating core line numbers

2 insulating dosage: (Kg/Km) = (D^2 - d^2) * 0.7854 * G * C * K2

D= insulation diameter d= conductor conductor G= insulated proportion K2= cored wire stranding ratio C= insulating core line numbers

3 The amount of outside: (Kg/Km) = (D1^2 - D^2) * 0.7854 * G

D1= diameter D= diameter G= insulation process of proportion

4 bag usage: (Kg/Km) = D^2 * 0.7854 * t * G * Z

The D= process t= diameter thickness G= package bag with proportion of Z= overlap ratio (1/4Lap = 1.25)

5 winding dosage: (Kg/Km) = d^2 * 0.7854 * G * N * Z

The d= wire diameter N= number G= ratio Z= stranding ratio

6 The amount of: woven (Kg/Km) = d^2 * 0.7854 * T * N * G / cos 

Theta = atan (2 * 3.1416 * (D + D * 2)) * mesh / 25.4 / T

D= braided copper wire diameter T= spindle number N= per spindle number G= copper proportion

Proportion: copper -8.89 -10.50; silver; zinc nickel aluminum -2.70; -7.05; -8.90; -7.30; -7.80 steel; lead -11.40 Mylar foil paper; -1.80; -1.35;, -1.37

PVC-1.45; LDPE-0.92; HDPE-0.96 EF -0.65; FRPE-1.7 (foam); Teflon (FEP) 2.2; Nylon-0.97 P-0.97 U-1.21
