Electrical and/or telecommunications cables with retro-reflective integral covering for use in aggressive environments with little or zero visibilty and the method for the production thereof

A process for manufacturing electric and/or telecommunications cables having retro-reflective integral covers to be used in harsh environments with low or null visibility, characterized by comprising a first drying step of the polymeric material or composition with or without a pigment to be processed;

• once the material is dried, the polymeric composition is fed for the body of the first cover layer with or without the pigment to an extrusion equipment and it is subjected to an extrusion step wherein the material is processed at a temperature from 85° C. to 225° C. and at a pressure at the extrusion header from 105 bar to 245 bar (1500 psi to 3500 psi);
• once the first cover layer has been extruded, the obtained product is fed to a taping step in order to incorporate at least one reflective tape with retro-reflective elements on the first cover layer, for which a taping machine incorporating at least one retro-reflective tape on the first cover layer according to the required array is used;
• once the product already has at least one tape applied, it is subjected to a final extrusion step together with a transparent polymeric composition, to carry out the extrusion of the third cover layer at temperatures in the extruder from 85° C. to 225° C. and at a pressure in the extrusion header from 105 bar to 245 bar (1500 psi to 3500 psi).
