2、ent A11:1999 has the status of a British Standard ICS 29.080.10BS EN 60383-1:1998 This British Standard, having been prepared under the directionof the Electrotechnical Sector Board, was published underthe authority of the Standards Board and comes intoeffect on 15October1998 BSI 02-2001 ISBN 0 580
3、30505 8 National foreword This British Standard is the English language version of EN60383-1:1996 including amendmentA11:1999. It is identical with IEC60383-1:1993. The UK participation in its preparation was entrusted by Technical Committee PEL/36, Insulators for power systems, to Subcommittee PEL/
4、36/2, Line insulators, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European devel
5、opments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. From1January1997, all IEC publications have the number60000 added to the old number. For instance, IEC27-1 has been renumbered as IEC60027-1. For a period of t
6、ime during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with thei
7、r corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electr
8、onic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This doc

The first five sections cover general clauses, including general requirements and relevant test procedures. Sections 6 to 9 deal with four different types of insulators: Section 6: Pin insulators Section 7: Line post insulators Section 8: String insulator units Section 9: Insulators for overhead electric traction lines. Sections6, 7 and8 begin with a cross-reference table giving the tests applicable to the insulators
