BS EN 50341-2-8:2017

What is BS EN 50341-2-8 - Overhead electrical lines about? 

BS EN 50341-2-8 is a European standard that discusses overhead electrical lines exceeding AC 1kV. Overhead lines are designed on the principle of one or more overhead wires situated over rail tracks. 

BS EN 50341-2-8 applies to the new overhead line as defined in 1.1/FR.2 "Definition of a new overhead line". A new overhead line denotes any new overhead electrical line exceeding AC 1 kV built on new foundations and: 

• Flanked by two substations or two terminal towers preceding said substations or 
• Flanked by a substation or a terminal tower at one end and in a branch situation (including branch tower) or tapping situation at the other end. 

Note: BS EN 50341-2-8 does not apply to existing overhead lines exceeding AC 1 kV in France. 

Who is BS EN 50341-2-8 - Overhead electrical lines for? 

BS EN 50341-2-8 on overhead electrical lines applies to: 

• Manufacturer of overhead electrical lines 
• Electrical engineer 
• Quality testing personnel 

Why should you use BS EN 50341-2-8 - Overhead electrical lines? 

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. 

BS EN 50341-2-8 provides guidance regarding the wind forces on insulators sets where the wind pressures are to be taken into on insulators sets which shall be stipulated in the project specification. 

BS EN 50341-2-8 provides you with comprehensive information which is useful for the overhead electrical line exceeding AC 1 kV. 

What’s changed since the last update? 

BS EN 50341-2-8:2017 supersedes BS EN 50423-3:2005 and BS EN 50341-3:2001, which is withdrawn.
