30、rial (resin insulators) or two or several insulating materials (composite insulators). The insulating materials are generally cross-linked organic materials synthesised from carbon or silicon chemistry and form the insulating body. Insulating materials can be composed from organic materials containi

31、ng various inorganic and organic ingredients, such as fillers and extenders. End fittings are often used at the ends of the insulating body to transmit mechanical loads. Despite these common features, the materials used and the construction details employed by different manufacturers may be widely d

32、ifferent. The tests given in this standard are those which are, in general, common to a great majority of insulator designs and materials, whatever their final application. They have been regrouped in this standard to avoid repetition in the relevant product standards and drift between procedures as

33、 the various product standards are drafted or revised. The majority of these tests have been grouped together as “Design tests“, to be performed only once for insulators of the same design. The design tests are intended to eliminate insulator designs, materials or manufacturing technologies which ar

34、e not suitable for high-voltage applications. The influence of time on the electrical properties of the complete polymeric insulator and its components (core material, housing, interfaces etc.) has been considered in specifying the design tests in order to ensure a satisfactory lifetime under normal

35、 operating and environmental conditions. Pollution tests, according to IEC 60507 or IEC 61245, are not included in this document, the applicability of their methodology to composite insulators not having been proven and still requiring study by CIGRE. The results of such pollution tests performed on

36、 insulators made of polymeric materials do not correlate with experience obtained from service. Specific pollution tests for polymeric insulators are still under consideration. The 1 000 hour salt-fog tracking and erosion test given in this second edition of IEC 62217 is considered as a screening te

37、st intended to reject materials or designs which are inadequate. This test is not intended to predict long term performance for insulator designs under cumulative service stresses. For more information, see Annex C. The first edition of IEC 62217 (2005) included two other alternative tracking and er

38、osion tests (a 5 000 hour multi-stress test and a tracking wheel test) which were based on tests developed by CIGRE and 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 erosio

39、n tests. The 5 000 hour multi-stress test and a tracking wheel test are described in IEC/TR 62730 (2012). Composite insulators are used in both a.c. and d.c. applications. In spite of this fact a specific tracking and erosion test procedure for d.c. applications as a design test has not yet been def

40、ined and accepted. The 1 000 hour a.c. tracking and erosion test described in this standard is used to establish a minimum requirement for the tracking resistance of the housing material. IEC Guide 111 has been followed wherever possible during the preparation of this standard. BS EN 62217:201362217

41、 IEC:2012 7 POLYMERIC HV INSULATORS FOR INDOOR AND OUTDOOR USE GENERAL DEFINITIONS, TEST METHODS AND ACCEPTANCE CRITERIA 1 Scope and object This International Standard is applicable to polymeric insulators whose insulating body consists of one or various organic materials. Polymeric insulators cover

42、ed by this standard include both solid core and hollow insulators. They are intended for use on HV overhead lines and in indoor and outdoor equipment. The object of this standard is to define the common terms used for polymeric insulators; to prescribe common test methods for design tests on polymer

43、ic 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 (see Clause 5). This standard shall only be applied in conjunction with the relevan

44、t product standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
