IEC 60273:1990

March 1990

International standard Current

Characteristic of indoor and outdoor post insulators for systems with nominal voltages greater than 1000 V

Applies to post insulators and post insulator units of ceramic material or glass intended for indoor or outdoor service, and to post insulators of organic material intended for indoor service in electrical installations or equipment operating on alternating current systems with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It may also be regarded as a provisional standard for insulators for use on direct current systems.
