This standard is applicable to ceramic insulated outdoor bushings for rated voltages of 24 kV and 36 kV, with rated currents of 5 kA and 8 kA and frequencies from 15 Hz up to 60 Hz for insulating liquid filled transformers. It establishes dimensions, to ensure interchangeability mounting of bushings. Two types of construction are specified, type A and type B, both types for rated voltages 24 kV and 36 kV and rated currents of 5 kA and 8 kA.
