Annotation of standard text IEC 62677-3-102-ed.1.0 :
IEC 62677-3-102:2018 is applicable to heat shrinkable medium voltage moulded shapes in a range of configurations suitable for insulation, environmental sealing, mechanical protection, strain relief for power cable terminations, joints and stop ends. These moulded shapes have been found suitable for use for temperatures between -40 °C and 100 °C. The moulded shapes can be supplied with a pre-coated adhesive. A guide to adhesive compatibility and temperature performance is given in Annex A. The manufacturers/suppliers can be consulted for options. Materials which conform to this document meet established levels of performance. However, the selection of a material by a user for a specific application will be based on the actual requirements necessary for adequate performance in that application and will not be based on this document alone. 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 IEC 60502 (all parts), EN 50393 and HD 629. Keywords: Heat-shrinkable, polyolefin, anti-tracking moulded shapes for medium voltage applications IEC 62677-3-102:2018 est applicable aux profiles thermoretractables moyenne tension dans une gamme de configurations adaptees a l’isolement, aux elements d’etancheite contre les intemperies, a la protection mecanique, aux dispositifs compensateurs de traction pour extremites de cables de puissance, aux joints et aux extremites darret. Ces profiles sont juges adaptes pour des utilisations dans la plage de temperatures de -40 °C a 100 °C. Les profiles peuvent etre fournis avec un adhesif prerevetu. LAnnexe A fournit un guide sur la compatibilite des adhesifs et la performance en temperature. Les fabricants/fournisseurs peuvent etre consultes pour les options. Les materiaux conformes au present document satisfont a des niveaux etablis de performance. Cependant, le choix d’un materiau par un utilisateur, pour une application specifique, sera fonde sur les exigences reelles necessaires pour obtenir une performance adequate pour lapplication concernee, et ne sera pas fonde sur ce seul document. Les essais specifies sont concus pour controler la qualite des profiles, mais il est reconnu quils sont concus pour etre utilises dans des accessoires de cables basse et moyenne tensions et, a ce titre, la performance electrique sera prouvee dans le cadre de lassemblage. Des exemples sont developpes dans lIEC 60502 (toutes les parties), lEN 50393 et le HD 629. Mots cles: Profiles thermoretractables anticheminement en polyolefine pour applications moyenne tension
