In a bushing used on a 36 kV 3-phase line consisting of two different insulating layers with relative dielectric constants Ԑr1= 1 and Ԑr2= 4, the conductor diameter is 25 mm and the flange (pedestal) diameter is 200 mm. There is air in the first layer and its puncture strength is Ed1= 30 kV/cm. Calculate the smallest value of the thickness of the air layer so that there is no discharge.
