Further, middle sheath is provided between the sheath and the outer jacket, the middle sheath is made using armouring aluminium strip.
Further, waterproof layer is provided between the middle sheath and the outer jacket, the waterproof layer is made using water blocking yarn.
Further, oxidation prevention layer is provided between the middle sheath and the sheath.
Further, the mounting framework that 3 installation cavitys are divided into for the circular space for surrounding which is provided with the sheath.
Further, three aluminium alloy cores are located in three installation cavitys respectively.
Further, also include the little core for arranging is corresponded with the aluminium alloy core, the external diameter of the little core is less than the external diameter of the aluminium alloy core, and the little core is made using aluminium alloy, and the little core is externally provided with using insulating barrier made by mica tape.
Further, the little core is arranged in the installation cavity that the corresponding aluminium alloy core is located.
The beneficial effects of the present invention is：
The aluminium alloy cable of the present invention, by sheath and outer jacket are arranged outside cable core, and sheath is made using mica tape, outer jacket is made using low-smoke halide-free fireproof composite polyolefine material, filled glass fiber packed layer and include arranging mica belt outside aluminium alloy core in the sheath, the structural strength of aluminium alloy cable can either be strengthened, its fire resistance can be strengthened again.
