The Italian NC ha
29、s prepared this Part 2-13 (EN 50341-2-13) listing the Italian National Normative Aspects (NNA) under its sole responsibility and duly passed it through the CENELEC and CLC/TC 11 procedures. NOTE: The Italian NC takes sole responsibility for the technically correct co-ordination of this NNA with EN 5
30、0341-1. It has performed the necessary checks in the frame of quality assurance/control. However, it is noted that this quality control has been already made in the framework of the general responsibility of a standards committee under the national laws/regulations. 3. This NNA is normative in Italy
31、 and informative for other countries. 4. 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 “IT”, are to be read as amendments to the relevant text in Part 1. Any necessary clarif
32、ication regarding the application of this NNA in conjunction with Part 1, shall be referred to the Italian NC who will, in co-operation with CLC/TC 11, clarify the requirements. When no reference is made in this NNA to a specific subclause, then Part 1 applies. 5. In the case of “boxed values” defin
33、ed in Part 1, amended values (if any), which are defined in this NNA, shall be taken into account in Italy. However, any boxed value, whether defined in Part 1 or in this NNA, shall not be amended in the direction of greater risk in a Project Specification. 6. The national Italian standards/regulati
34、ons related to overhead electrical lines exceeding 1 kV (AC) are listed in subclause 2.1/IT.1 and 2.1/IT.2. NOTE: All national standards referred to in this NNA will be replaced by the relevant European Standards as soon as they become available and are declared by the Italian NC to be applicable an

36、oltages above 1kV AC. This standard is not applicable to overhead lines pre-existing before its coming into force and shall not be applied to maintenance or reconductoring; the standard can be applied in case of significant modifications of existing lines. 1.2 Field of application (ncpt) IT.1 Field
37、of application This standard specifies the general safety requirements, clarifies the actions that shall be carried out in the project and their relevant combinations, defines the characteristics of materials, products and any other aspects relevant to safety of electrical overhead lines as reported
38、 in the following clause 2. With reference to structural safety aspects, in absence of specific indications, and as an integration to this standard, the dispositions reported in “Norme tecniche sulle costruzioni” apply (see subclause 2.1). For what concerns structural aspects this standard applies a
39、lso to D.C. overhead lines. For details concerning the application of this standard to telecommunication systems involving optical fibres either incorporated in or wrapped around earth-wires or conductors or suspended from overhead line supports, reference should be made to the Project Specification
