RE: Transmition lost in Kw/m

sounds like a home work assignment...this is too basic a question to ask if you are assigned to design a tranmission line.

Ask your senior engineers..

Hint: kw loss= I^2*R. Calculate values per phase. Multiply by three for the total 3 phase loss. Refer to some basic text books, hand books etc.

There other more serious things to consider in tranmission line design. An when it is overhead line, like urs, mechanical, sturctural and civil engineering plays much greater role than electrical.
