Overhead electrical lines exceeding AC 45 kV - Part 3: Set of National Normative Aspects EN 50341-3:2001

Publication date:   Sep 12, 2003

Scope

Field of application:
AT.1 Notes 1, 2 and 3 are normative in Austria:

NOTE 1 The extent of the application of this standard is defined in Austrian „Elektrizitätsverordnung –
ETV“.

NOTE 2 The construction of lines with covered conductors (KUF) and reduced internal or external
clearance is not permitted in Austria. For KUF-lines the prescriptions for clearances as from 5.4.2.1 apply.

NOTE 3 In addition to the text from Part 1 the following applies:

These regulations also cover telecommunication lines which are carried on supports of OH high voltage
lines. These regulations are not valid for constructions of conductors or cables with integrated optical fibres
independent from their function which do not have simultaneously the function of a conductor or an earth
wire. For such constructions the normal additional load as from 4.3.3 and the exceptional additional loads
with minimum 12 N/m are to be considered.

For such constructions with metallic materials internal clearances as defined in 5.4.2.1 apply.
