Test requirements on accessories for use on power cables of rated voltage from 3,6/6(7,2) kV up to 20,8/36(42) kV - Part 1: Cables with extruded insulation
This standard specifies performance requirements for type tests for cable accessories for use on extruded insulation power cables as specified in HD 620. Formerly, approvals of such products have been achieved on the basis of national standards and specifications and/or the demonstration of satisfactory service performance. The publication of this CENELEC standard does not invalidate existing approvals. However, products approved to such earlier standards or specifications shall not claim approval to this CENELEC standard unless specifically tested to it. It is not necessary to repeat these tests, once successfully completed, unless changes are made in the materials, design or manufacturing process, which might affect the performance characteristics. Accessories for special applications such as submarine cables, ships cables or hazardous situations (explosive environments, fire resistant cables or seismic conditions) are not included. Test methods are included in EN 61442.
Prüfanforderungen für Kabelgarnituren für Starkstromkabel mit einer Nennspannung von 3,6/6(7,2) kV bis 20,8/36(42) kV - Teil 1: Kabel mit extrudierter Kunststoffisolierung
Diese Norm gilt für die Anforderungen bei Typprüfungen für Kabelgarnituren in Verbindung mit extrudierten Kunststoffkabeln wie in HD 620 beschrieben. In der Vergangenheit erfolgte die Zulassung von Garnituren auf der Basis nationaler Normen und Bedingungen und/oder dem Nachweis hinreichender Betriebsergebisse. Durch die Veröffentlichung dieser CENELEC Norm werden bestehende Zulassungen nicht ungültig. Jedoch gelten Gernituren, typgeprüft nach früheren Normen oder Bedingungen, nicht als nach dieser CENELEC-Norm typgeprüft, solange sie nicht diesem entsprechend geprüft wurden. Nachdem diese Prüfung erfolgreich bestanden wurde braucht diese nicht wiederholt werden, es sei denn, Änderungen in Material, Konstruktion oder Herrstellprozess welche die Betriebseigenschaften beeinflussen können, wurden vorgenommen. Diese Norm gilt nicht für Garnituren für spezielle Anwendungsbereiche, z.B. Seekabel, Schiffskabel oder für den Einsatz unter gefährlichen Bedingungen (explosive Umgebung, feuerbeständige Kabel oder Erdbebengefährdung). Die Prüfverfahren sind in EN 61442 enthalten.
Prescriptions relatives aux essais sur les accessoires des câbles d'énergie pour des tensions assignées de 3,6/6(7,2) kV à 20,8/36(42) kV - Partie 1: Câbles à isolation extrudée
Le présent Document d'Harmonisation définit les prescriptions fonctionnelles concernant les essais de type sur les accessoires de câbles d'énergie à isolation extrudée spécifiés dans le HD 620. Auparavant, les agréments de ces accessoires ont été réalisés sur la base de normes ou spécifications nationales et/ou sur la base d’une démonstration d’une expérience en service satisfaisante. La publication de cette norme CENELEC n’invalide pas les agréments existants. Cependant, des accessoires agréés sur la base de normes ou spécifications antérieures ne peuvent revendiquer un agrément suivant la présente norme CENELEC tant qu’ils n’ont pas subit les essais de celle-ci. Une fois ces essais effectués, il n'est pas nécessaire de les répéter sauf si des changements intervenant dans les matériaux, la conception ou le procédé de fabrication, sont susceptibles d'affecter les caractéristiques de fonctionnement. Les accessoires pour usages spéciaux tels que les câbles sous-marins, les câbles de bord ou pour situations dangereuses (environnements explosifs, câbles résistant au feu ou aux conditions sismiques) ne sont pas traités par cette norme. Les méthodes d’essais sont décrites dans la EN 61442.

SIST HD 629.1 S2 : 2006
1 Področje uporabe
1.1 Splošno
Ta standard določa tehnične zahteve za preskuse tipa za kabelski pribor za uporabo elektroenergetskih
kablov z ekstrudirano izolacijo, kot je predpisano v HD 620.
Odobritve za take proizvode so bile nekdaj pridobljene na podlagi nacionalnih standardov in specifikacij
in/ali predstavitve zadovoljive obratovalne zmogljivosti. Objava tega standarda CENELEC ne
razveljavlja obstoječih odobritev. Vendar pa za proizvode, ki so bili odobreni na podlagi takih prejšnjih
standardov ali specifikacij, ni mogoče zahtevati odobritve po tem standardu CENELEC, razen če niso
posebej preskušeni po tem standardu.
Teh preskusov ni treba ponavljati, potem ko so uspešno končani, razen če niso bile izvedene
spremembe v materialih, zasnovi ali proizvodnji, ki bi lahko vplivale na tehnične karakteristike.
Vključen ni pribor za posebno uporabo, kot so podmorski kabli, ladijski kabli ali kabli za nevarne situacije
(eksplozivna okolja, ognjeodporni kabli ali potresni pogoji).
Preskusne metode so vključene v EN 61442.
1.2 Vrsta pribora
Pribor, ki ga obravnava ta standard, je naveden spodaj:
a) notranji in zunanji končniki vseh izvedb, vključno s končniškimi omaricami,
b) (navadne) spojke, odcepne spojke in slepi končniki vseh izvedb, primerni za uporabo v zemlji ali
zraku,
c) zaslonjeni ali nezaslonjeni vtični ali vijačni ločljivi konektorji, primerni kot vmesniki s skoznjiki, kot
je določeno v EN 50180 in EN 50181.
OPOMBA: Spojke za spajanje kablov z ekstrudirano izolacijo (HD 620) in kablov s papirno izolacijo (HD 621) niso vključene.
Zahteve za ta pribor obravnava HD 629.2.
