Abstract

772,054. Insulators. COOKE & FERGUSON, Ltd. Sept. 13, 1955 [June 18, 1954], No. 17997/54. Drawings to Specification. Class 36. An insulating bushing comprising a homo. geneous mass of cast resin has continuous cylindrical stress-distribution layers of predetermined diameters embedded therein. The insulator may be built up from a number of tubes of resin fitting within one another, the conducting cylinders being arranged in the spaces between the tubes which are subsequently filled with casting resin which is allowed to cure or set. The cylinders may be formed on the outside of the tubes as by painting, spraying or dipping. Alternatively, a tube of resin is cast around a former and coated with conductive material, further tubes being cast therearound and coated. In a third method, thin-walled conductive tubes are arranged inside one another and surrounding a former in a mould which is then filled with casting resin which is allowed to cool or set.
