Annotation of standard text IEC 60840-ed.5.1+Amd.1-CSV :
IEC 60840:2020+AMD1:2023 CSV specifies test methods and requirements for power cable systems, cables alone and accessories alone, for fixed installations and for rated voltages above 30 kV (Um = 36 kV) up to and including 150 kV (Um = 170 kV). The requirements apply to single-core cables and to individually screened three-core cables and to their accessories for usual conditions of installation and operation, but not to special cables, such as submarine cables and their accessories, for which modifications to the standard tests or the setup of special test conditions can be necessary. This document does not cover transition joints between cables with extruded insulation and paper insulated cables. This fifth edition cancels and replaces the fourth edition, published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Gas immersed cable terminations for use at rated voltages above 52 kV are required to be designed, type and routine tested in accordance with IEC 62271-209 in addition to the routine and type tests specified in this document. - Requirements are introduced for composite outdoor termination insulators. - The test cylinder diameters specified for the bending test (type and prequalification tests) have been modified in line with IEC TR 61901:2016. - A low smoke halogen free oversheath material, designated ST12 is introduced. - Additional tests under fire conditions are introduced: vertical flame spread, smoke density, acidity and conductivity, which shall be applied according to the fire performance declared for the cable. - A test for water penetration in the conductor is added. - In addition to tests on the outer protection of joints, type tests on the screen sectionalizing insulation of all accessories have been introduced. The contents of the corrigendum of February 2021 have been included in this copy. LIEC 60840:2020+AMD1:2023 CSV specifie les methodes et les exigences dessai applicables aux systemes de cables denergie, cables seuls et accessoires seuls, pour installations fixes, pour des tensions assignees superieures a 30 kV (Um = 36 kV) et jusqua 150 kV (Um = 170 kV) inclus. Les exigences sappliquent aux cables unipolaires, aux cables tripolaires a ecran individuel et a leurs accessoires, pour des conditions habituelles dinstallation et de fonctionnement, mais pas aux cables speciaux, tels que les cables sous-marins et leurs accessoires, pour lesquels il peut etre necessaire dapporter des modifications aux essais normaux ou delaborer des conditions dessai particulieres. Les jonctions assurant le raccordement des cables a isolant extrude aux cables isoles au papier ne sont pas couvertes par le present document. Cette cinquieme edition annule et remplace la quatrieme edition parue en 2011. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - il est exige que les extremites de cable immergees dans du gaz pour une utilisation a des tensions assignees superieures a 52 kV soient soumises a des essais de type et des essais individuels de serie conformement a lIEC 62271-209 en plus des essais individuels de serie et des essais de type specifies dans le present document; - les exigences relatives aux isolateurs composites pour extremites de cable exterieures ont ete introduites; - les diametres des cylindres dessai specifies pour lessai denroulement (essais de type et de prequalification) ont ete modifies conformement a lIEC TR 61901:2016; - un materiau de gaine exterieure sans halogene a faible degagement de fumee, appele ST12 a ete introduit; - les essais supplementaires des cables soumis au feu (propagation verticale de flammes, densite de fumees, acidite et conductivite) qui doivent etre appliques conformement aux performances de resistance au feu declarees pour le cable ont ete introduits; - un essai de penetration deau dans lame a ete ajoute; - en plus des essais des protections externes des jonctions, les essais de type de larret decran ont ete etendus a tous les accessoires. Le contenu du corrigendum de fevrier 2021 a ete pris en consideration dans cet exemplaire.
