EN 50423-3 Overhead Power Lines AC Exceeding 1 kV and AC Up to 45 kV - Part 3: National Set of Normative Guidelines

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 50423-3 testing. The construction of lines with closed conductors (KUF) and reduced internal or external clearance is permitted in Austria.

This NNA applies to overhead lines with a rated voltage exceeding AC 60071kV up to (inclusive) AC 1 kV according to ÖVE EN 45-1 and a maximum operating voltage of 52 kV. From now on, the latter will be described as high-voltage overhead lines, group I.

When a conductor passes an object, as a result of being deflected by the incoming wind, the direction of that facility intersects the conductor's outline, the conductor's outline.

In the case of angular suspension, in the wind bisector direction perpendicular to the direction of the line, the towers move according to: tower, equipment, and ice-free conductors.

Under special conditions, if conductor pulls are assumed to be reduced or completely stopped, it should be assumed that the corresponding least favorable stress of the component to be rated will be applied as a result.
