This standard is applicable to indoor, outdoor-indoor wall-through porcelain bushings (abbreviated as bushings) and bushings used in three-phase AC system power stations and substation power distribution devices with a rated voltage of 6-35kV and a frequency of 15-60Hz. The ambient temperature of the installation site should be -40～+40℃. See Appendix A of GB4109 for the use of bushings when the ambient temperature exceeds +40°C. The casing is suitable for horizontal installation, and the indoor casing can be installed vertically. This standard does not apply to bushings used under conditions sufficient to degrade bushing performance and to condensation on parts of the interior of the bushing.
