| 摘要 |
The present invention is related to electric and/or telecommunications cables having retro-reflective integral covers to be used in harsh environments with low or null visibility and the manufacturing process thereof. Cables of the present invention comprise a core capable of incorporating a plurality of electric and/or telecommunications conductors, reinforcement elements and/or filler elements; a first protective cover layer wrapping the core; at least one reflective tape including visible external light retro-reflective elements, and wrapping the first protective cover layer, which constitutes a second cover layer; and a third protective cover layer wrapping the second cover layer, constituted by the reflective tape having retro-reflective elements and the first protective cover layer. The first protective cover layer, the reflective tape with retro-reflective elements forming the second protective cover layer and the third protective cover layer, once formed, together form an integral cover surrounding the core. |
