Abstract
The paper presents the results of a study on the use of high dielectric constant silicone housing compositions on composite bushings to shape the electric stress in the vicinity of the mounting flange, thereby eliminating the need for separate grading rings or capacitor foils. The materials studied are various mixtures of barium titanate and aluminum powder in a two-part RTV silicone yielding a dielectric constant of 15, and sufficiently low in concentration as not to affect the molding properties of the silicone.
