Aluminum-core low-smoke halogen-free flame-retardant medium-voltage flame-resistant cable

The utility model discloses an aluminum-core low-smoke halogen-free flame-retardant medium-voltage flame-resistant cable. A core of the cable is formed by three phases of metal shielding wire cores in a twisting mode, a filler layer is arranged in the gap of the cable core, an inner taped covering, a flame-resistant layer, an outer taped covering and a sheath layer are sequentially arranged outside the cable core and the filler layer, and each metal shielding wire core is sequentially composed of an aluminum conductor, a conductor shielding layer, an insulation layer, an insulation shielding layer and a metal shielding layer from inside to outside. The aluminum-core low-smoke halogen-free flame-retardant medium-voltage flame-resistant cable has the advantages of being flame-resistant, light in weight, high in transmission voltage, high in flame-retardant performance, low-smoke, free of halogen, low in price and cost, and long in flame-resistant time, thereby being suitable for being used in stations, squares, hospitals, hotels, stadiums, metros, high-rise buildings and other public places requiring low-smoke halogen-free flame-retardant flame-resistant power transmission.
