Annotation of standard text IEC 62896-ed.1.0 :
IEC 62896:2024 applies to hybrid insulators for AC and DC applications greater than 1 000 V AC and 1 500 V DC consisting of a load-bearing insulating solid or hollow core consisting of ceramic or glass, a housing (defined geometry, outside the insulating core) made of polymeric material and end fittings permanently attached to the insulating core. Hybrid insulators covered by this document are intended for use as suspension/tension long rod and cap and pin type insulators, line post insulators, station post insulators and hollow core insulators for apparatus. The object of this document is to: - define the terms used; - prescribe test methods; - prescribe acceptance criteria This document does not include requirements dealing with the choice of insulators for specific operating conditions. This first edition cancels and replaces the IEC TS 62896 published in 2015. This edition includes the following significant technical changes with respect to the previous edition: - modifications of terms and definitions; - modifications of tests procedures included in IEC TR 62039 and IEC 62217 (Hydrophobicity transfer test); - harmonization of Table 1 (Tests to be carried out after design and type changes) with other product standards and IEC 62217. L’IEC 62896:2024 s’applique aux isolateurs hybrides pour applications en courant alternatif et en courant continu superieures a 1 000 V en courant alternatif et 1 500 V en courant continu, constitues d’un noyau isolant supportant la charge mecanique, plein ou creux, fabrique en matiere ceramique ou en verre, d’un revetement (de geometrie definie, a l’exterieur du noyau isolant) en materiau polymere et d’armatures d’extremite fixees de facon permanente au noyau isolant. Les isolateurs hybrides couverts par le present document sont destines a etre utilises comme isolateurs de suspension/d’ancrage de type a long fut et de type capot et tige, isolateurs rigides a socle, isolateurs supports et isolateurs a noyau creux, pour l’appareillage. Le present document a pour objets: - de definir les termes employes; - de prescrire des methodes d’essai; - de prescrire les criteres d’acceptation. Cette premiere edition annule et remplace l’IEC TS 62896 parue en 2015. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: - modifications des termes et definitions; - modifications des procedures d’essai incluses dans l’IEC TR 62039 et l’IEC 62217 (Essai de transfert d’hydrophobicite); - harmonisation du Tableau 1 (Essais a realiser apres les modifications de conception et de type) avec d’autres normes de produit l’IEC 62217.
