Abstract
1,263,465. Electrical insulators. CENTRAL ELECTRICITY GENERATING BOARD. 1 April, 1969 [1 April, 1968; 19 Dec., 1968], Nos. 15576/68 and 60467/68. Heading H2C. In an electrical insulator having a plurality of sheds of N different diameters arranged in a repeating pattern of 2<SP>(N-1)</SP> sheds, where N is equal to or greater than 3, and wherein the shed size number is given by the highest power of 2 that is exactly divisible into the position number in the repeating pattern, the total length of the creepage path between the ends of the insulator is at least 4 times the axial length. The uppermost shed has the largest diameter and a line touching the outer extremity of a shed at an angle of 30 degrees to the insulator axis intercepts only a shed of the same or larger diameter. The sheds may be inclined at an angle of about 50 to 65 degrees with the insulator axis and have flat curved or tapered surfaces, which may further be corrugated or stepped. The body of the insulator may be formed integrally with the sheds as a single porcelain element or formed as moulded resin insulators on a resin-bonded glass fibre core.
