| description | The utility model relates to the technical field of power cables, in particular to a 0.6-1kV super-large-section buried low-smoke halogen-free flame-retardant power cable. The cable comprises a wire core with a super-large cross section, and is characterized in that the wire core is formed by twisting a plurality of layers of circular copper conductors or special-shaped copper conductors, a steel strand core is arranged in the wire core, an inner insulating layer is arranged on the outer layer of the wire core, a low-smoke halogen-free flame-retardant layer is arranged outside the inner insulating layer, a water-blocking wrapping tape layer is arranged outside the inner insulating layer, and a water-blocking wrapping tape layer is arranged outside the water-blocking wrapping tape layer. An inner sheath is arranged outside the water-blocking wrapping tape layer, an armor layer is arranged outside the inner sheath, a glass fiber composite layer is arranged outside the armor layer, and an outer sheath is arrange |
