Abstract

La présente invention concerne une corde en résine synthétique comprenant des brins constitués de fibres en résine synthétique et fibres conductrices torsadées, les fibres en résine synthétique étant retirées à leur extrémité afin de laisser apparaître la résine conductrice qui est ensuite intégrée à un adhésif conducteur permettant sa solidification, et est sertie par un métal d'extrémité, ce qui permet de garantir une connexion électrique entre le métal d'extrémité au niveau de l'extrémité et les fibres conductrices internes.
