Overview
This International Standard is applicable to polymeric insulators whose insulating body consists of one or various organic materials. Polymeric insulators covered by this standard include both solid core and hollow insulators. They are intended for use on high voltage overhead lines and in indoor and outdoor equipment. The purpose of this standard is - to define the general terms used for polymeric insulators; - to prescribe common test methods for design tests on polymeric insulators; - to prescribe acceptance or failure criteria, if applicable. These tests, criteria and recommendations are intended to ensure a satisfactory life-time under normal operating and environmental conditions. This standard may only be applied in conjunction with the relevant product standard. The following significant technical change has been made with respect to EN 62217:2006: EN 62217:2006 included two other alternative tracking and erosion tests (a 5 000 hour multi-stress test and a tracking wheel test) which were based on tests developed by CIGRE and electric utilities. These tests are no longer given as normative alternatives following the results of a study/questionnaire by TC 36 on the relative merits of all three tracking and erosion tests. The 5 000 hour multi-stress test and a tracking wheel test are described in IEC/TR 62730:2012. The responsible committee is DKE/K 451 "Isolatoren" ("Insulators") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
