The invention provides a flame retardant aluminium alloy power cable, relating to the technical field of cable manufacture. The cable comprises four groups of insulated cable cores. A double-layer flame-retardant glass fiber belt layer and a low-smoke halogen-free polyolefin sheath layer are orderly arranged outside the four groups of insulated cable cores which are twisted together. Each group of insulated cable cores comprises an aluminum alloy conductor, and a double-layer flame-retardant mica belt layer and a cross-linked polyethylene insulating layer are orderly arranged outside the aluminum alloy conductor. The flame retardant aluminium alloy power cable has the advantages of simple and reasonable structure, high safety performance, good electrical performance and flame retardant properties.
Description
technical field [0001] The present invention relates to the technical field of cable manufacturing. Background technique [0002] With the development of economic science and the promotion of industry, most cables currently use copper conductors. Due to the high cost of copper conductors, aluminum alloy cables are recognized by the national grid in developed countries. Compared with aluminum alloy cables and copper core cables, Its advantages are: 1) Under the same cross-section, the current-carrying capacity of the aluminum alloy cable conductor is twice that of the copper conductor; 2) The creep resistance of the cable ensures the continuous and stability of the cable when it is overloaded and overheated; 3) The aluminum alloy cable is light and convenient in construction; 4) the practical life of the cable is longer than that of the copper cable; 5) the aluminum alloy cable is lower in cable cost. As a result, people began to use aluminum alloy cables to replace copper c...
