Multicore conductor or cable prodn. - uses tape wound on stranded filled cable cores, with lay shorter than that of cores

摘要

The multiple wire electrical cable cores are stranded, and a filler is placed between the outer strands. The strands and then the filling are wound with a textile tape in opposite directions with wide spacings. An outer sheath is extruded on the cable so prepared. The lay of the above winding is shorter than that of the cores (2). The outer sheath (8) is continuously extruded in the same operation, and is supplied with adhesive at the same time. The outer and inner sheaths are vulcanised after the adhesion process.
