GB/T 12944-2011 High-voltage ceramic wall bushings
Abstract
This standard specifies the technical requirements, test requirements, structural types, dimensions, and characteristics of high-voltage wall-penetrating porcelain bushings.
This standard applies to indoor and outdoor wall-penetrating porcelain bushings (hereinafter referred to as "bushings") used in power stations and substations of three-phase AC systems with a nominal voltage of 6 kV to 35 kV and a frequency of 15 Hz to 60 Hz.
The bushings are suitable for horizontal installation, and indoor bushings can be installed vertically.
This standard does not apply to bushings used under conditions that can reduce the performance of the bushings or when the surface of the indoor end of the bushings condenses with dew.
