Section: claims

1. An electrically conductive textile yarn for the production of protective garments for conducting maintenance on live high-voltage wires, wherein the said yarn comprises:a first element comprising one or more electrically conductive threads, each of the electrically conductive threads comprising a core composed of polyamide covered with a layer of silver; anda second element, which is different from the said first element, and comprises one or more threads provided with good resistance to fire, the second element not comprising metallic or mineral fibres;the yarn being produced by twisting together one or more threads of the second element with one or more electrically conductive threads of the first element;wherein the fraction by weight of the electrically conductive threads of the first element compared with the weight of said yarn is approximately 30%-35%. 2. The electrically conductive textile yarn according to claim 1, wherein the said second element consists substantially of fibres selected from the group comprising: aramide fibres, meta-aramide fibres, and flame-retardant cotton. 3. The electrically conductive textile yarn according to claim 2, wherein the second element also has anti-static properties and/or anti-bacterial properties, and/or properties of resistance to acids or bases and/or of resistance to temperatures higher than 200° C. 4. The electrically conductive textile yarn according to claim 1, wherein the second element also has anti-static properties and/or anti-bacterial properties, and/or properties of resistance to acids or bases and/or of resistance to temperatures higher than 200° C. 5. A garment comprising a layer created by a yarn according to claim 1 wherein a surface area of the said layer is substantially equal to the surface area of the garment.
