ABSTRACT

Basic requirements about reliability, security and safety conditions of the overhead electrical lines are presented in accordance with European Code EN 50341-1:2001. Actions on overhead lines and load cases on supports have been classified. Basic design assumptions used in analysis of lattice steel towers are announced and limit state method has been consistently introduced to structural design of overhead electrical lines.

 

KEYWORDS
