Anotation

Applies to post insulators and post insulator units of ceramic material or glass for indoor and outdoor service in electrical installations or equipment operating on alternating current with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. Notes: -May also be regarded as a provisional standard for insulators for use on d.c. systems, see IEC 60438. -When considering hollow insulators, see IEC 60233. -Tests on indoor post insulators of organic material will be covered by a future publication: Tests on indoor post insulators of organic material for systems with nominal voltages greater than 1 000 V up to but not including 300 kV. -For artificial pollution and radio-interference tests, see IEC 60437 and 60507. -For numerical values for insulator characteristics and for selection of insulators for specific operating conditions, see IEC 60273. Sapplique aux supports isolants et elements de supports isolants dinterieur et dexterieur, en matiere ceramique ou en verre, destines a lequipement dinstallations ou dappareils electriques fonctionnant en courant alternatif a une tension nominale superieure a 1 000 V et a une frequence au plus egale a 100 Hz. Notes: 1. Cette norme peut aussi etre consideree comme sappliquant provisoirement aux supports isolants destines aux reseaux fonctionnant en courant continu, voir CEI 60438. 2. Lorsquil sagit disolateurs creux, voir CEI 60233. 3. Les essais des supports isolants dinterieur en matiere organique feront lobjet dune future publication: Essais des supports isolants dinterieur en matiere organique destines a des installations de tension nominale superieure a 1 000 V jusqua 300 kV non compris. 4. Pour les essais de pollution artificielle et de perturbations radioelectriques, voir CEI 60437 et 60507. 5. Pour les valeurs numeriques de caracteristiques disolateur et pour la selection dun isolateur en fonction du service quil doit assurer, voir CEI 60273.
