SCK0 - Gas Insulated Substations

WGK7 – HV Bushings (>1kV) for CBs and GIS (Joint with Switchgear Committee)

Scope: This standard is applicable to bushings intended for use in high-voltage circuit breakers and gas- insulated switchgear. These bushings areintended for indoor and outdoor use, operating on alternating current with a rated voltage greater than 1000 V and a frequency of 50 Hz or 60 Hz. These bushings are usually a part of an apparatus and tested according to the apparatus of which they form part. Insulators or bushings 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.
This standard does not apply to the following:
a) High-voltage cable terminations
b) Bushings for instrument transformers
c) Bushings for test transformers
d) Bushings for power transformers
e) Bushings for oil-filled circuit breakers
f) Oil-filled bushings in general
g) Capacitor bushings

Standard: IEEE C37.017-2010 – IEEE Standard for Bushings for High-Voltage [over 1000 V (ac)] Circuit Breakers and Gas-Insulated Switchgear
