ABSTRACT:
A bushing for insulating a conductor in a high-voltage electrical transmission system is fabricated of paper and metallic foil disposed as coaxial layers about the conductor. At one end of the bushing, the paper is impregnated with oil. At the opposite end of the bushing, the paper is impregnated with a resin which cures to a solid form. The paper, oil and resin serve as electrical insulators, while the metallic foil serves to disperse uniformly the electric field. A mounting flange is positioned on an enclosing casing for setting the resin end of the bushing into the housing of an electrical apparatus to which the bushing may be mounted so as to prevent contamination of the interior of the housing with the oil.
