Summary:866,265. Inserting conductors into resilient sheaths. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 30, 1957 [Oct. 8, 1956], No. 30633/56. Class 108(3). [Also in Groups XXXV and XXXVI] A solid electrical conductor or group of solid electrical conductors, e.g. a dynamoelectric machine armature bar, is insulated by a method in which a tube of silicone rubber or other electrically insulating material having similar elastic properties is collapsed on to the conductor(s) after expansion by air pressure only, by applying over one end of the conductor(s) the end of the tube remote from that connected to an air pressure source, controlling the air leakage from the tube whilst moving the remote end thereof along the conductor(s), and then releasing the air pressure so that the tube immediately contracts down on to the conductor(s). The leakage may be controlled by finger pressure or a short tubular member slidable along the conductors, the tube movement may be eased by a compatible lubricant e.g. silicone rubber paste, and the tube expansion may be limited by an enclosing sleeve. The insulation may be mechanically protected by a lapped tape of, e.g., glass reinforced silicone rubber, fused to the tube.
