Abstract:
1. Method for manufacturing an electrical cable system having an electrical cable containing a conductor core, and for installing said electrical cable system over a longitudinally expandable-contractible element, said method comprising the steps of: disposing a secondary element over said electrical cable, said secondary element being a radially expandable hose, so as to give said electrical cable substantially attached undulations thereby forming an additional length, said additional length formed by stranding said radially expandable hose around said electrical cable in a helical formation, where said electrical cable and said radially expandable hose are both twisted relative to one another; installing, by clamping at least at two points, said electrical cable system to said longitudinally expandable-contractible element; and handling said secondary element after said clamping so as to release the attachment of said undulations, thereby converting said additional length into a free to be used excess length.
