BS EN 50423-1 is included on a CD containing: BS EN 50341 (Parts 1-3) - Overhead lines exceeding AC 45 kV and BS EN 50423 (Parts 1-3) - Overhead lines up to and including 45 kV. This CD is intended to be the definitive \'UK guide to standardisation for Overhead Electrical Lines?? [see attached supplementary info entitled \'BS EN 50423 (supplemenatry info)\'] and brings together the standards pertaining to above and below 45kV working. There is also the added benefit of providing purchasers with the latest combined NNAs for the UK Overhead Line industry whilst directing them to the correct referencing within each standard. The UK \'combined NNAs\' are located in BS EN 50423-3-9, and these NNAs replace BS EN 50341-3-9.
