Line resistance

Considering the same length of the cable, the line resistance is greater in DC than in AC

The resistivity increases linearly with the temperature in the working range

Standard conductors have a lower resistance than solid ones

Conductors arranged in bundles have a better behavior against skin effect

The correction factor in the expression of the line resistance is within the range of 0≤k≤1

At high frequency, line resistance and internal inductance tend to the same value

Overhead lines are based on Aluminum conductors
