i need software or file to explain how to calculate the cross section of cables with loss voltage,temperature effect and cable wrapping together.

hi
Calculation of the cross section , entering the diameter d = 2 r:
Formula calculate cross-sectional area from diameter
r = radius of the wire or cable
d = 2 r = diameter of the wire or cable
Calculation of the diameter d = 2 r, entering the cross section :
Formula calculate diameter from cross-sectional area
Hi
Cross section is just a two-dimensional view of a slice through an object.
An often asked question: How can you convert the diameter of a round wire d = 2 × r to the
circle cross section surface or the cross-section area A (slice plane) to the cable diameter d?
Why is the diameter value greater than the area value? Because that's not the same.
Resistance varies inversely with the cross-sectional area of a wire.
The required cross-section of an electrical line depends on the following factors:
1) Rated voltage. Net form. (Three-phase (DS) / AC (WS))
2) Fuse - Upstream backup = Maximum permissible current (Amp)
3) On schedule to be transmitted power (kVA)
4) Cable length in meters (m)
5) Permissible voltage drop (% of the rated voltage)
6) Line material. Copper (Cu) or aluminum (Al)
