This paper is aimed at the experimental study of creeping discharges and flashover of cylindrical epoxy solid insulators with and without barrier. The effect of pressure and the shape of insulators surface are discussed. It is shown that the position of barrier with respect to the high voltage electrode affects the flashover voltage unlike its thickness.
