Abstract
A method for producing a sector conductor for electric power cables is introduced, whereby a number of metal wires are joined closely together into a core (8) with a sector-shaped cross section. A lengthwise running metal strip is formed around the core (8) and its longitudinally abutting edges are welded into a tube (9), whose dimensions are reduced so that it lies closely against the core (8) and surrounds it.
Claims5
A method for producing a sector conductor for electric power cables, the method comprising the steps of:
- (a) providing a number of metal wires joined closely together into a core with a sector-shaped cross section;
- (b) forming a lengthwise running metal strip into a slotted tube around the core, the slotted tube having longitudinally abutting edges;
- (c) welding the longitudinally abutting edges to form a welded tube;
- and
- (d) reducing the welded tube so that it lies closely against the core and surrounds it so as to form a sector conductor which sustantially forms a sector of a circle.
