Dear all, 

what is the compacting ratio of copper conductor?
How to calculate the area of sector conductor?
For power cable how much percentage to be increased the drawn wire size from the standard wire size.?

what is the compacting ratio of copper conductor?

1. it is defined IEC 60228 and it is about %4 lover than stranded wire.

How to calculate the area of sector conductor?

2. you can check here

For power cable how much percentage to be increased the drawn wire size from the standard wire size.?

3. it depends on you equipment , because standards give us only max. conductor resistance.

Dear all,
    Copper compacting ratio is 0.95-0.97%,but this is suitable for solid conductor only,if am using this ratio in circular stranded conductor also minor air gaps will takes place,so obviously CR will go higher side,so kindly let me the solution regarding this problem.
1)we need increse the wire size in drawing section?
2)How much compacting ratio will keep in stranding circular conductor?
