Insulators for overhead lines with a nominal voltage above 1000 V - Part 1: Ceramic or glass insulator units for a.c. systems - Definitions, test methods and acceptance criteria

This part of IEC 60383 applies to insulators of ceramic material or glass for use on a.c. overhead power lines and overhead traction lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to insulators for use on d.c. overhead electric traction lines.
This part applies to string insulator units, rigid overhead line insulators and to insulators of similar design when used in substations.
lt does not apply to insulators forming parts of electrical apparatus or to parts used in their construction or to post insulators which are covered by IEC 60168: Tests on indoor and outdoor post insulators of ceramic material or glass for systems with nominal voltages greater than 1 000 V.
Tests on insulator strings and insulator sets (for example, wet switching impulse voltage) are dealt with in part 2 of IEC 60383.
The object of this part is:
- to define the terms used
- to define insulator characteristics and to prescribe the conditions under which the specified values of these characteristics shall be verified
- to prescribe test methods
- to prescribe acceptance criteria.
This part does not include requirements dealing with the choice of insulators for specific operating conditions.
Specific requirements on the use of coatings on ceramic or glass insulators are described in the informative Annex C.
NOTE A guide for the choice of insulators under polluted conditions has been published, see IEC 60815-1 and -2.
Numerical values for insulator characteristics are specified in IEC 60305, IEC 60433 and IEC 60720.

179 FOREWORD
180 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
181 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
182 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
183 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
184 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
185 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
186 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
187 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
188 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
189 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
190 consensus of opinion on the relevant subjects since each technical committee has representation from all
191 interested IEC National Committees.
192 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
193 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
194 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
195 misinterpretation by any end user.
196 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
197 transparently to the maximum extent possible in their national and regional publications. Any divergence between
198 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
199 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
200 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
201 services carried out by independent certification bodies.
202 6) All users should ensure that they have the latest edition of this publication.
203 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
204 members of its technical committees and IEC National Committees for any personal injury, property damage or
205 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
206 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
207 Publications.
208 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
209 indispensable for the correct application of this publication.
210 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
211 rights. IEC shall not be held responsible for identifying any or all such patent rights.

213 This 5 edition cancels and replaces the 4 edition published in 1993. This edition constitutes
214 a technical revision.

217 a) The complete document has been revised and updated. The layout of the document has
218 been changed in order to increase the readability.
219 b) RIV test has been added (clause 14)
220 c) Impulse puncture test in air has been added (clause 15.1)
221 d) Residual strength test has been added (clause 21)

240 INTRODUCTION
241 This standard deals with four different types of insulators:
242  Pin insulators
243  Line post insulators
244  String insulator units
245  Insulators for overhead electric traction lines
246 The user of this part need only refer to the clause dealing with the type of insulator to be tested
247 and to the general requirements and relevant test.
