Abstract
1,129,995. Insulators. MICANITE & INSULATORS CO. Ltd. 8 Dec., 1965 [8 Dec., 1964], No. 49909/64. Heading H2C. An electric insulating bushing is made by winding side-by-side on to a former or the like at least two sheets of flexible insulating material, e.g. paper, which initially overlap a distance W and are then cut by a reciprocating cutter in this overlapping region as they are fed forward together on to the former to produce complementary abutting serrated or tapered edges, as shown in the Figure. The pitch of the serrations is so related to the circumferential length of the layers that the abutting edges of adjacent layers are displaced laterally from one another, Fig. 4 (not shown). Layers of foil may be interleaved with the insulating sheeting to reduce electric stress. The insulation may be increased by impregnating the bushing material with, for example, an insulating oil or gas, or a plastics resin that may be cured during fabrication of the bushing by using heated rollers. Figs. 1 and 2 (not shown) illustrate the arrangement of the rollers and sheeting in the apparatus used in the method.
