The utility model relates to the technical field of electric wires and cables, in particular to a low-smoke halogen-free flame-retardant super-A cable, comprising a skin, a triangular skeleton and a plurality of conductive wires, wherein the skin wraps the triangular skeleton, and the triangular skeleton is A plurality of cavities are opened inside, and a plurality of the conductive wires are evenly distributed in each cavity. From the outside to the inside, there are a sheath layer and a copper tape. The material of the sheath layer is a silane type low-smoke halogen-free flame retardant polyolefin. The utility model is provided with a triangular skeleton, and the triangular skeleton is made of silica gel, and the silica gel has It has good flexibility and can be easily bent and wound. When the cable is impacted or under pressure, the triangular skeleton can play a good buffering role; at the same time, the design of the bee triangle, the triangle has good stability, and can also improve the overall compression resistance of the triangular skeleton. strength. |
