US 2013/0280420 A1 · COMPOSITE CABLE

Abstract

A method for manufacturing a composite cable comprises providing a number of electrical conductors which are each covered by insulation, providing a number of fibres for strength, coating the fibres with a liquid thermosetting or thermoplastic resin to form a fibre-resin matrix comprising a number of resin-coated fibres, combining the resin-coated fibres and the conductors to form the cable, and pulling the resultant cable through a curing station to cure the fibre-resin matrix. Before the curing station, the resin-coated fibres are passed through a pre-shaper stage where the fibres are arranged with an orientation parallel to each other and to the conductors and are guided through two guiding plates and at least one pre-shaper element.

e) pulling the resultant cable through a curing station to cure the fibre-resin matrix;
wherein the resin-coated fibres pass through a pre-shaper stage prior to the curing station where the fibres are arranged with an orientation parallel to each other and to the conductors;
wherein in the pre-shaper stage the resin-coated fibres are guided through two guiding plates and at least one pre-shaper element;
and
wherein the amount of fibres in the finished cable is above 60%.
