Overhead lines - Requirements and tests for Aeolian vibration dampers

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. Key words: Overhead Lines, Aeolian Vibration Dampers

IEC 61897:2020 est disponible sous forme de IEC 61897:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. IEC 61897:2020 s'applique aux amortisseurs de vibrations éoliennes pour conducteurs uniques ou câbles de garde, ou aux faisceaux de conducteurs lorsque les amortisseurs sont directement reliés à chaque sous-conducteur. L'acheteur peut adopter un ou plusieurs fragments du présent document lors de la spécification d'exigences concernant des câbles différents de ceux mentionnés ci-dessus, par exemple les câbles de garde optiques (OPGW, Optical Ground Wire) ou les câbles optiques autoporteurs entièrement diélectriques (ADSS, All Dielectric Self-Supporting). Dans certains cas, les procédures et valeurs d'essai sont convenues entre l'acheteur et le fournisseur et sont indiquées dans le contrat d'approvisionnement. L'annexe A contient les informations techniques minimales à convenir entre l'acheteur et le fournisseur. Dans le cadre du présent document, le mot "conducteur" est utilisé lorsque l'essai s'applique aux amortisseurs pour conducteurs ou câbles de garde.
