BS PD IEC/TS 62896:2015 applies to hybrid insulators for a.c. and d.c. applications consistingof 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 fittingspermanently attached to the insulating core.
Hybrid insulators covered by this technical specification are intended for use assuspension/tension line insulators, line post insulators, station post insulators and hollow coreinsulators for apparatus.
The object of this technical 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), boostersheds, shed extenders and rain deflectors are not within the scope of this technicalspecification.
This technical specification does not include requirements dealing with the choice of insulatorsfor specific operating conditions.
