Overhead lines are supported by sections of transmission towers.
Electricity pylons are used for the higher tension lines.
A drveni ili betonski stupovi obično se koriste za vodove manje napetosti.
This is because higher tension lines (linija najveće napetosti) mora biti instaliran na velikoj visini, jer zahtijevaju veći sigurnosni razmak.
Only electrical pylons can afford to carry lines of tens of tons.
