BS EN 50341-2-16 is part of the BS EN 50341 standard that discusses the national normative aspects for Norway for overhead electrical lines exceeding AC 1 kV. Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses and trains.
BS EN 50341-2-16 is applicable for new permanent overhead lines only and generally not for existing lines in Norway. If some planning/design or execution work on existing lines in Norway has to be performed, the degree of application of BS EN 50341-2-16 shall be agreed upon by the parties concerned and the authorities.
BS EN 50341-2-16 on overhead electrical line applies to:
Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses and trains. Overhead lines are designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along with the overhead line supply power from the high-voltage grid.
BS EN 50341-2-16 provides you with the guidance of various types of loads that helps in the action on lines which includes self-weight of supports, insulator sets, other fixed equipment and the conductors from the adjacent spans. Climate loads include wind, ice and combined wind and ice loads on conductors, insulator sets, lattice towers and poles. Security loads include wire breakage. Safety loads consider the safety of the linesmen and also prevent the collapse of the support by including load cases that may occur during construction and maintenance.
As a user of BS EN 50341-2-16, you can ensure the quality of the products by having a quality assurance and check by National Normative Aspects Norway for Overhead electrical lines.
