适用范围：This standard applies to hollow insulators made of ceramic material, with their fixing devices, intended for use with a permanent gas pressure greater than 0.5 bar having an internal volume equal to or greater than 1 litre (1000cm3). They are intended for use in electrical equipment operating on alternating current with a rated voltage greater than 1000 V and a frequency not greater than 100 Hz or for use in direct current equipment with a rated voltage greater than 1500 V.The hollow insulators covered by this standard consist of hollow insulator bodies, open from end to end, with or without sheds.Note 1 : The gas can be: dry air. inert gases, e.g. sulphur hexafluoride or nitrogen or a mixture of such gases.Note 2 : The hollow insulators are intended for use in electrical equipment, for example :- Circuit-breakers,- Switch-disconnectors,- Disconnectors.- Earthing switches,- Instrument transfomners.- Surge arresters.- Bushings,- Cable sealing ends.This standard supplements, and modifies if necessary, HD 329 (IEC 233) which applies to the body of hollow insulators.
