This Technical Specification is applicable to capacitance graded outdoor bushings with values of highest voltage for equipment (Um) from 52 kV up to 420 kV and with values of rated current (Ir) up to 3 150 A and frequencies from 15 Hz up to 60 Hz for oil immersed transformers. The major insulation of these bushings consists either of oil-impregnated or resin-impregnated paper or other suitable insulating systems. This Technical Specification establishes essential details and dimensions to ensure interchange ability and adequate mounting of the bushings.
