适用范围：This Technical Specification applies to- ceramic and glass hollow insulators intended for general use in electrical equipment;- ceramic hollow insulators intended for use with a permanent gas pressure in switchgear and controlgear.They are intended for indoor and outdoor use in electrical equipment, operating on alternatingcurrent with a rated voltage greater than 1 000 V and a frequency not greater than 100 Hz orfor use in direct current equipment with a rated voltage greater than 1 500 V.This specification specifies the dimensional and mechanical characteristics of the hollowinsulator, which are essential for interchangeability of the hollow insulator of the same type. Itis not the object of this specification to prescribe electrical characteristics because they aredependent on the apparatus of which the hollow insulator ultimately forms a part. However,standard lightning impulse withstand voltage which is provided in IEC 60071-1 is describedonly for reference for classification purpose.This specification applies to hollow insulators for use in electrical equipment in clean areas orlightly polluted areas, where seismic qualification is not required. For use in areascharacterised by heavy pollution levels and for other particular or extreme environmentalconditions such as seismic force, it may be necessary for certain dimensions to be changed.The hollow insulators covered by this specification are:a) straight type hollow insulators with metal fittings on both ends;b) taper type hollow insulators with metal fittings on both ends;c) straight type hollow insulators without metal fittings;d) taper type hollow insulators without metal fittings.The hollow insulators are intended for use in electrical equipment, for example:- circuit-breakers;- instrument transformers;- surge arresters;- bushings;- cable sealing ends;- switch-disconnectors;- disconnectors;- earthing switches;- capacitors.There may be some cases that hollow insulators whose design can strongly be influenced byother components of specific equipment, for example, active parts of circuit-breakers. Forsuch cases, the hollow insulators can be separately designed, depending on respectiverequirements of such equipment and not be covered by this specification.NOTE 1 Hollow insulators not prescribed in this specification can also be applied to electrical equipment,depending on specific requirements of the equipment. However, if similar insulators are available in thisspecification, it is preferable to apply them.NOTE 2 For general recommendations for design and tests of the hollow insulators, see IEC 62155NOTE 3 For characteristics of hollow insulators for use in polluted areas, reference can be made to IEC 60815-1and IEC 60815-2.
