In DC transmission line construction design, current national standard of economicalcurrentdensity will under predictcd conductor section, resulting in large loss.
According to the viewpoint of economic effect of induStrial enterpriSe, Several expreSSionS of economicalcurrentdenSity for overhead line conductorS are derived in thiS paper.
