ČSN EN 50341-2-2

This NNA has to be read in conjunction with Part 1 (EN 50341-1). All clause numbers used in this NNA correspond to those of Part 1. Specific subclauses, which are prefixed "BE", are to be read as amendments to the relevant text in Part 1. Any necessary clarification regarding the application of this NNA in conjunction with Part 1 shall be referred to the Belgian NC who will, in co-operation with CLC/TC11, clarify the requirements. Where no reference is made in this NNA to a specific subclause, then Part 1 applies. In case of "boxed values" defined in Part 1, amended values (if any), which are defined in this NNA shall be taken into account in Belgium. However, any boxed value, whether in Part 1 or this NNA, shall not be amended in the direction of greater risk in a Project Specification. The national Belgian standards/regulations related to overhead electrical lines exceeding 1 kV (AC) are listed in subclauses 2.1/BE.1 and BE.2. Only significant extracts and summaries of the Belgian national regulations are presented in the A-deviations. They must be read in conjunction with the Belgian national regulations identified in 2.1/BE.1 which is in any case the relevant document.
