EVS-EN 50341-3-20:2007

EE.1 Application to existing overhead lines This Part 3-x is applicable for new high voltage overhead transmission lines only, not for existing lines in Estonia. In other cases (i.e. major revisions of existing lines) the applicability of this Part 3-x shall be determined case by case in each project by the line owner or the competent authority. EE.2 Application of covered conductors Requirements for the design and construction of overhead lines with application of covered conductors will be specified in the Project Specification. EE.3 Application of cables for telecommunication This Part 3-x is not valid for constructions of conductors or cables with integrated optical fibres independent from their function which do not have simultaneously the function of a conductor or an earth wire. EE.4 Application to mounting of telecommunication equipment This Part 3-x is not applicable for fixing of structural elements for telecommunication (e.g. dishes), if these are mounted on power line supports (towers). Mounting of telecommunication equipment will be specified in the Project Specification and the requirements of ENV 1993-3-1 (Towers and Masts) have to be taken into account, too.
