Overview
This Technical Specification applies to hybrid insulators consisting of a load-bearing insulating solid or hollow core consisting of ceramic or glass, a housing (outside the insulating core) made of polymeric material and end fittings permanently attached to the insulating core. Hybrid insulators covered by this Technical Specification are intended for use as suspension/tension line insulators, post insulators and hollow core insulators for apparatus. The object of this specification is to - define the terms used; - prescribe test methods; - prescribe acceptance criteria. Silicone or other functional coatings (CIGRE Technical Brochure No. 478, Appendix B), silicone booster sheds, shed extenders and rain deflectors are not within the scope of this Technical Specification. This Technical Specification does not include requirements dealing with the choice of insulators for specific operating conditions. The responsible committee is DKE/K 451 "Isolatoren" ("Insulators") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
