1、BRITISH STANDARD BS EN 62155:2003 Incorporating Corrigendum No. 1 Hollow pressurized and unpressurized ceramic and glass insulators for use in electrical equipment with rated voltages greater than 1000 V The European Standard EN 62155:2003 has the status of a British Standard ICS 29.080.10 BS EN 621

2、55:2003 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 October 2003 BSI 26 July 2004 ISBN 0 580 42838 9 National foreword This British Standard is the official English language version of EN 62155:2003. It is identical with IEC 62155:2003

3、. It supersedes BS 4963:1973 and BS EN 61264:1999, which will be withdrawn on 2006-05-01.

These insulators are intended for indoor and outdoor use in electrical equipment, operating on alternating current with a rated voltage greater than 1 000 V and a frequency not greater than 100 Hz or for use in direct-current equipment with

11、a rated voltage of greater than 1 500 V. The hollow insulators are intended for use in electrical equipment, for example: circuit-breakers, switch-disconnectors, disconnectors, earthing switches, instrument transformers, surge arresters, bushings, cable sealing ends, capacitors. It is not the object

12、 of this standard to prescribe dielectric type tests because the withstand voltages are not characteristics of the hollow insulator itself but of the apparatus of which it ultimately forms a part. 1.2 Hollow insulators or hollow insulator bodies intended for general use Hollow insulators or insulato
