Selection of Conductor Size and Type For MV Line Design

 Selection of Conductor Size and Type For MV Design

Factors influencing selection include:

a) Load current and whether the line is 'backbone' or a spur;

b) Line voltage and voltage profile along the line;

c) Fault levels and line rating;

d) Environmental conditions – ambient temperature, vegetation, wildlife, pollution or salt spray;

e) Compatibility with existing adjacent electrical infrastructure;

f) Required span lengths and stringing tension; and

g) Future requirements with respect to distribution system planning.
