bushings intended for use in high voltage
circuit breakers and gas insulated switchgear.
These bushings are intended for indoor and
outdoor use, operating on alternating current
with a rated voltage greater than 1000
V and a frequency of 50 or 60 Hz. These
bushings are usually a part of an apparatus
and tested according to the apparatus of

used as an element of metal-enclosed
switchgear assemblies, or in reclosers,
sectionalizers, or similar equipment, are not
included in the scope of this document.
