Karakteristikat e izolatorëve mbështetës për përdorim të brendshëm dhe të jashtëm për sisteme me tensione nominale me të mëdha se 1 kV

Characteristics of indoor and outdoor post insulators for systems with nominal voltages greater than 1 kV

Scope

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.
