BS EN 50423-3 applies to overhead lines with nominal voltage exceeding AC 1kV up to and including AC 45 kV and a maximum operating voltage of 52 kV according to ÖVE EN 60071-1. Hereinafter the latter will be described as high voltage overhead lines, group I.
BS EN 50423-3 on overhead electrical lines is helpful for:
Having access to reliable guidelines is essential to prepare and use quality overhead electrical lines. BS EN 50423-3 provides manufacturers with the construction and maintenance requirements along with the electrical requirements which allows them to effectively manufacture and test overhead electrical lines.
BS EN 50423-3 provides users with efficient and standardized overhead electrical lines.
