Overhead electrical lines exceeding AC 1 kV - Part -2-7: National Normative Aspects (NNA) for FINLAND (based on EN 50341-1:2012)
SIST EN 50341-2-7:2024

1.1 General (ncpt) FI.1 Application of the standard in Finland In Finland the standard EN 50341-1 (Part 1) can only be applied using this NNA (EN 50341-2-7) containing National Normative Aspects for Finland. The requirements of the standard are applied also for low voltage (below 1 kV AC) overhead lines. The requirements of the structural design are applicable also for DC overhead lines, where the electrical requirements are given in the Project Specification. This standard is applicable for new overhead lines only. (ncpt) FI.2 Application for existing overhead lines Overhead lines complying with the mechanical and electrical requirements of its original date of construction can be operated and maintained, if they do not cause obvious danger. The reparation and overhaul of lines can be done according to the previous requirements. Reparation means that a component which has been damaged is substituted with a similar new one. Overhaul means a wider improvement of the line for extending its lifetime. The basic structure remains same as before. This standard should be used for all modification works on existing lines. In modification works earlier norms and standards may also be used. In that case it shall especially be verified that changes in actions do not have significant impact on the loads of lines. Modification work means e.g. relocation of some supports or an extension to a line when this supplement has been taken into account in the original design, e.g. addition of a circuit or changing of the conductors to existing supports. 1.2 Field of application (ncpt) FI.1 Application to covered conductors and aerial cables The standard includes requirements for the design and construction of overhead lines equipped with covered conductors and aerial cables. Additionally, the requirements of the equipment standards and manufacturers’ instructions shall be followed. (ncpt) FI.2 Application to cables for telecommunication The standard includes requirements for the application of telecommunication cables installed on common supports with electrical lines. (ncpt) FI.3 Installation of other equipment Only equipment belonging to the line (electric or telecommunication line) can be installed on the overhead lines. However, equipment serving communal services or environmental protection like telecommunication equipment, road signs, warning signs or warning balls may also be installed with the permission of the owner of the line. Other equipment than those mentioned above can also be installed on supports equipped with aerial cables with the permission of the owner of the line. If other equipment is installed on the supports, the requirements of safe working practices shall be taken into account. The installation height of equipment meant to be installed and maintained by an ordinary person shall be such that the work can be done without climbing the support and the distances of safe electrical work can be followed (see standard SFS 6002). The additional loads due to other equipment on the line supports shall be taken into account.

Overhead electrical lines exceeding AC 1 kV - National Normative Aspects (NNA) for Slovenia (based on EN 50341-1:2012)
SIST EN 50341-2-21:2023

SI.1 Definition of the new overhead power line
A new overhead power line is defined as a functionally completed installation for the
transmission of electricity between points A and B (i.e. the new construction of all
conductors, their supports together with foundations, earthing system, insulators,
accessories and fittings).
The overhead lines currently being designed (starting of a design to obtain a building
permit) or being under construction may be completed in accordance with the standards
in force at the time of the start of the design or construction of the overhead line.
In the case of maintenance and renovation works with major structural changes to
overhead lines, this standard shall be applied in accordance with the project
specification. E.g., for the construction of new support on new foundations in the existing
overhead line, the provisions of this standard shall be applied to support and foundations
but for the other elements of the overhead line don’t need to be complied with this
standard.
For the design and construction of DC overhead lines, the requirements of this standard
are also applicable to the design of structures, but not for electrical requirements, which
have to be specified in the project specification.

IEC 61897:2020 is available as IEC 61897:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61897:2020 applies to aeolian vibration dampers intended for single conductors or earth wires or conductor bundles where dampers are directly attached to each subconductor. The purchaser may adopt part(s) of this document when specifying requirements for cables different from those mentioned above (e.g. optical ground wires (OPGW), all dielectric self-supporting optical cables (ADSS)). In some cases, test procedures and test values are left to agreement between the purchaser and the supplier and are stated in the procurement contract. Annex A lists the minimum technical details to be agreed between purchaser and supplier. Throughout this document, the word “conductor” is used when the test applies to dampers for conductors or earth wires. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Consider, in addition to Stockbridge type aeolian vibration dampers, also spiral aeolian vibration dampers and elastomeric aeolian vibration dampers. b) Consider the application of dampers on high temperature conductors, specifying additional high temperature tests in clamp slip tests. c) Simplify the procedure of the damper effectiveness evaluation. d) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers. e) Include figures showing the test arrangements for the main mechanical tests.

IEC 61854:2020 is available as IEC 61854:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61854:2020 applies to spacers for conductor bundles of overhead lines. It covers rigid spacers, flexible spacers and spacer dampers. It does not apply to interphase spacers, hoop spacers and bonding spacers. This document is written to cover the line design practices and spacers most commonly used at the time of writing. There may be other spacers available for which the specific tests reported in this document may not be applicable. In some cases, test procedures and test values are left to agreement between purchaser and supplier and are stated in the procurement contract. The purchaser is best able to evaluate the intended service conditions, which should be the basis for establishing the test severity. In Annex A, the minimum technical details to be agreed between purchaser and supplier are listed. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Consider the application of spacers on high temperature conductors specifying additional high temperature tests in clamp slip tests and for the characterization of elastic and damping properties; b) Specify as far as possible test parameters and acceptance values; c) Avoid as far as possible the alternative procedures for the same test; d) Introduce a simpler test device for the simulated short circuit current test; e) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers; f) Prescribe a different procedure for subspan oscillation tests on spacers equipped with clamps having rod attachments; g) Modify the test procedure for the aeolian vibration tests; h) Prescribe a different procedure for aeolian vibration tests on spacers equipped with clamps having rod attachments; i) Re-edit all the figures in order to make them more clear and homogeneous; j) Introduce an additional test device for the simulated short circuit current test.
