Classic: formula for calculating the amount of wire and cable materials

For example, 120 mm² calculation: 120*8.89 = 1066.8 kg/km

1 conductor usage: (Kg/Km) = d ^ 2*0.7854 * G * N * K1 * K2 * C

D = copper wire diameter G = copper proportion N = bars K1 = copper wire twisting rate K2 = core wire twisting rate C = insulation core wire number

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

D = Insulation Outer diameter d = conductor outer diameter G = insulation proportion K2 = core cable twisting rate C = number of insulation core wires

3 External usage: (Kg/Km) = (D1 ^ 2-D ^ 2) * 0.7854 * G

D1 = outer diameter D = outer diameter G = insulation proportion

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

D = outer diameter t = tape thickness G = tape proportion Z = overlap rate (1/4Lap = 1.25)

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

D = copper wire diameter N = number of bars G = proportion Z = twisting Rate

6. Weaving dosage: (Kg/Km) = d ^ 2*0.7854 * T * N * G/cos θ

θ = atan (2*3.1416 * (D + d * 2) * Number of projects/25.4/T

D = braided copper wire diameter T = number of ingots N = number of ingots G = copper proportion letter

Proportion: copper-8.89; Silver-10.50; Aluminum-2.70; zinc-7.05; nickel-8.90; Tin-7.30; Steel-7.80; Lead-11.40; aluminum foil-1.80; paper-1.35; Mara-1.37

PVC-1.45; LDPE-0.92; HDPE-0.96; ave (foam)-0.65; FRPE-1.7; Teflon (FEP) 2.2; Nylon-0.97; PP-0.97; PU-1.21
