Electrical cable price calculation
The cost of electric wire and cable consists of three parts:
1. the cost of copper or aluminium
2. PVC (outer material) cost
3. labor costs
 
Cable cost calculation
1. Conductor dosage:(Kg/Km)=d2 × 0.7854 × G × N × K1 × K2 × C 
d=Copper wire diameter G=Copper specific gravity N=number K1=Copper wire twist rate K2=Cored wire
2. Insulation dosage:(Kg/Km)=(D2 - d2)× 0.7854 × G × C × K2
D=Insulation outside diameter d=Conductor Outside Diameter G=Insulation specific gravity K2=Copper wire twist rate C=Number of insulated wire
3.amount of outer:(Kg/Km)= ( D12 - D2 ) × 0.7854 × G
D1=overall diameter D=Outside diameter G=Insulation proportion
4.Package tape:(Kg/Km)= D2 × 0.7854 × t × G × Z
D=Outside diameter t=package tape thiness G=package tape proportion Z=Overlap ratio(1/4Lap = 1.25)。
5.Winding dosage:(Kg/Km)= d2 × 0.7854 × G × N × Z
d=copper wire diameter N=number G=proportion Z=wire twist rate
6.Knitting dosage:(Kg/Km)= d2 × 0.7854 × T × N × G / cosθ
θ = atan( 2 × 3.1416 × ( D + d × 2 )) × mesh number / 25.4 / T
d=Braided copper wire diameter T=Spindle number N=number of every spindle G=copper proportion
