Overhead electrical lines exceeding AC 1 kV up to and including AC 45 kV - General requirements. Common specifications not-for-sale Entities involved in fire safetyBS EN 50423 1: 2005 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
