Izolatorët e kalimit për tensionet alternative mbi 1 kV

Insulated bushings for alternating voltages above 1 kV

Scope

Specifies the characteristics and tests for insulated bushings. Is applicable to bushings, as defined in clause 2, intended for use in electrical apparatus, machinery, transformers, switchgear and installations for three-phase alternating current systems, having rated voltages above 100 V and power-frequencies of 15 Hz up to and including 60 Hz. Special requirements and tests for transformer bushings in this standard apply also to reactor bushings. This standard may also be used analogously for bushings for use in other than three-phase systems, e.g. for rectifiers, testing transformers, or for terminals for power cables (potheads) and capacitors.
