Heat shrinkable low and medium voltage moulded shapes - Part 2 Methods of test

IEC 62677-2:2017 gives methods of test for heat shrinkable low and medium voltage moulded shapes in a range of configurations and materials suitable for insulation, environmental sealing, mechanical protection and strain relief for connector/cable terminations and multi-way transitions. The tests specified are designed to control the quality of the moulded shapes but it is recognized that they are designed to be used in low and medium voltage cable accessories and as such electrical performance will be proven as part of the assembly. Examples of this are described in EN 50393, HD 629.1 and IEC 60502-4.

Profilés thermorétractables basse et moyenne tensions - Partie 2: Méthodes d’essai

IEC 62677-2:2017 décrit des méthodes d'essai des profilés thermorétractables basse et moyenne tensions dans une gamme de configurations et de matériaux adaptés à l’isolement, aux éléments d’étanchéité contre les intempéries, à la protection mécanique et aux dispositifs compensateurs de traction pour les connecteurs/extrémités de câbles et aux transitions à conducteurs multiples. Les essais spécifiés sont conçus pour contrôler la qualité des profilés, mais il est reconnu qu'ils sont conçus pour être utilisés dans des accessoires de câbles basse et moyenne tensions et, à ce titre, la performance électrique sera prouvée dans le cadre de l'assemblage. Des exemples sont développés dans l'EN 50393, le HD 629.1 et l'IEC 60502-4. Mots clés: profilés thermorétractables basse et moyenne tensions

Toplotno skrčljive nizko- in srednjenapetostne ulite forme - 2. del: Metode preskušanja (IEC 62677-2:2017)

Ta del IEC 62677 opisuje metode preskusov za toplotno skrčljive nizko- in srednjenapetostne oblikovance v različnih konfiguracijah in iz različnih materialov, primernih za izolacijo, zaščito pred okoljskimi vplivi, mehansko zaščito in razbremenitev za ozemljitve priključkov/kablov in večsmernih prenosov.
Opisani preskusi so namenjeni nadzoru nad kakovostjo oblikovancev, pri čemer se upošteva, da so zasnovani za uporabo z nizko- in srednjenapetostnimi kabli, zato se kot del sestava preverja tudi električna zmogljivost. Primeri tega so opisani v standardih EN 50393, HD 629.1 in IEC 60502-4.
