the lines which transmit power from these substation
consumers is called distrubution...

A very high voltage is transmitted to reduce losses...

The main thing we consider transmission or distrubution
is "SAG"calculation... sag of line directly propotional to
the weight of the conductor,distance between the poles etc..
