Compression and mechanical connectors for power cables - Part 1-3: Test methods and requirements for compression and mechanical connectors for power cables for rated voltages above 1 kV (Um = 1,2 kV) up to 36 kV (Um = 42 kV) tested on non-insulated conductors

This part of EN 61238 applies to compression and mechanical connectors for power cables for rated voltages above 1 kV (Um = 1,2 kV) up to 36 kV (Um = 42 kV), for example buried cables or cables installed in buildings, having a) conductors complying with EN 60228 having nominal cross-sectional areas between 2,5 mm2 and 1 200 mm2 for copper and between 16 mm2 and 1 200 mm2 for aluminium, excluding Milliken conductors; b) a maximum continuous conductor temperature not exceeding 90 °C. This document is not applicable to connectors for overhead line conductors nor to connectors with a sliding contact. The object of this document is to define the type test methods and requirements which apply to compression and mechanical connectors for power cables with copper or aluminium conductors. The reference method is to perform the tests on unused conductors.

Pressverbinder und Schraubverbinder für Starkstromkabel - Teil 1-3: Prüfverfahren für und Anforderungen an Pressverbinder und Schraubverbinder für Starkstromkabel für Nennspannungen über 1 kV (Um = 1,2 kV) bis zu 36 kV (Um = 42 kV), geprüft an nicht isolierten Leitern

Raccords sertis et à serrage mécanique pour câbles d’énergie - Partie 1-3: Méthodes et exigences d’essai relatives aux raccords sertis et à serrage mécanique pour les câbles d’énergie de tensions assignées supérieures à 1 kV (Um = 1,2 kV) jusqu’à 36 kV (Um = 42 kV) soumis à essai sur des conducteurs non isolés

L’IEC 61238-1-3:2018 est applicable aux raccords sertis et à serrage mécanique pour câbles d'énergie de tensions assignées supérieures à 1 kV (Um = 1,2 kV) jusqu’à 30 kV (Um = 36 kV), par exemple pour les câbles enterrés ou ceux installés à l'intérieur des bâtiments, ayant a) des âmes conformes à l’IEC 60228, de section nominale comprise entre 2,5 mm2 et 1 200 mm2 pour le cuivre et entre 16 mm2 et 1 200 mm2 pour l’aluminium, à l’exception des âmes Milliken; b) une température maximale de fonctionnement en service permanent au plus égale à 90 °C. Le présent document n'est pas applicable aux raccords pour conducteurs de ligne aérienne ni aux raccords équipés d’un contact glissant. L'objet du présent document est de définir les méthodes d'essais de type et les exigences qui s’appliquent aux raccords sertis et à serrage mécanique utilisables sur les câbles d'énergie à conducteurs en cuivre ou en aluminium. La méthode de référence consiste à réaliser les essais sur des conducteurs neufs. Cette première édition, conjointement avec l'IEC 61238-1-1 et l'IEC 61238-1-2, annule et remplace l'IEC 61238-1:2003. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC 61238-1:2003: a) Le domaine d’application a été élargi afin de couvrir les raccords de connexion pour âmes jusqu’à 2,5 mm2 (précédemment 10 mm2); il a été limité à 1 200 mm2 pour les âmes en cuivre et en aluminium car les expériences et applications d’essai des raccords à perforation d’isolant sont rares pour les âmes de fortes sections. b) Une nouvelle classe mécanique a été introduite pour répondre à la demande concernant les raccords soumis à des forces mécaniques supérieures à celles spécifiées dans la Classe 1 pour les âmes de fortes sections. c) Pour l’essai électrique, un courant de chauffage élevé maximal a été défini afin d’éviter l’apparition de densités de courant irréalistes pendant l’essai, qui peuvent modifier les propriétés des raccords en essai. d) Pour l’essai de court-circuit, la méthode de calcul et les exigences ont été mises à jour. e) Pour l’essai mécanique, les méthodes et exigences ont été mises à jour. f) Une proposition d’essai électrique sur les cosses d’extrémité de câble a été introduite pour les applications de connecteurs séparables.

Stisljivi in vijačni konektorji za električne kable - 1-3. del: Preskusne metode in zahteve za stisljive in vijačne konektorje za električne kable za naznačene napetosti nad 1 kV (Um = 1,2 kV) do 36 kV (Um = 42 kV), preskušene na neizoliranih vodnikih (IEC 61238-1-3:2018)

Ta del standarda EN 61238 se uporablja za stisljive in vijačne konektorje za električne kable za naznačene napetosti nad 1 kV (Um = 1,2 kV) do 36 kV (Um = 42 kV), na primer za v zemljo položene kable ali kable, vgrajene v stavbah, ki imajo:
a) vodnike, ki so skladni s standardom EN 60228 ter imajo nominalni premer med 2,5 mm2 in 1200 mm2, če so bakreni, ter med 16 mm2 in 1200 mm2, če so aluminijasti, razen segmentnih vodnikov.
b) največjo enakomerno temperaturo vodnika, ki ne presega 90 °C.
Ta dokument se ne uporablja za konektorje vodnikov nadzemnih vodov ali za konektorje z drsnimi kontakti.
Namen tega dokumenta je opredeliti metode in zahteve tipskih preskusov, ki se uporabljajo za stisljive in vijačne konektorje za električne kable z bakrenimi ali aluminijastimi vodniki. Referenčna metoda je namenjena za izvajanje preskusov na neuporabljenih vodnikih.
