Patent number: 6063998Abstract: A cable head, in which ends of cable cores, made of a plurality of individual stranded conductors, are inserted into the bore holes of a cable lug. The cable cores are fixed in position in the bore holes by radial pressing and deformation of the bore holes. The bore holes are located on divided circles which are concentric relative to each other, the bore holes on the inner divided circle being staggered with respect to the bore holes on the outer divided circle. Cooling-water grooves between the bore holes located on the outer divided circle extend, with a depth, into the proximity of the bore holes arranged on the inner divided circle. They are connected to a central cooling-water channel in the cable head.Type: GrantFiled: June 30, 1998Date of Patent: May 16, 2000Assignee: KM Europa Metal AGInventors: Thomas Rolf, Christof Dratner
