Εναέριες ηλεκτρικές γραμμές πάνω από 1 kV εναλλασσόμενου ρεύματος και μέχρι 45 kV εναλλασσόμενου ρεύματος - Μέρος 1: Γενικές απαιτήσεις - Κοινές προδιαγραφές

This standard applies to bare and covered conductor overhead lines and overhead insulated cable systems with nominal voltage exceeding AC 1 kV up to and including AC 45 kV and with rated frequencies below 100 Hz. In general the requirements in EN 50341-1 apply. This standard specifies additional requirements and simplifications that apply only for this voltage range. In connection with EN 50341-1, this standard specifies the general requirements that shall be met for the design and construction of new overhead lines to ensure that the line is suitable for its purpose with regard to safety of persons, maintenance, operation and environmental considerations. This standard does not apply to: – overhead electric lines inside closed electrical areas as defined in HD 637 S1; – catenary systems of electrified railways unless explicitly required by another standard.
