摘要 |
Power cables intended for working under extreme conditions of heat and temperature are prone to deterioration and/or destruction of their protective layers, and it is therefore extremely important, for safety reasons, that said cables be made of fire-resistant materials, which are flame-retardant in the event of a fire. The present invention proposes obtaining a power and/or telecommunications cable which includes at least: an electric and/or optical conductor element, covered with at least one electrically insulating layer, also optionally including a protective layer surrounding one or more insulated conductor elements, having the special feature that the cover and/or insulation of the cable includes: a) an extrusible organic polymer or a mixture of several extrusible organic polymers; b) an inorganic phosphate arranged hierarchically on phyllosilicates; and c) other secondary inorganic fillers. |
