Unlike traditional copper cable, AAAC conductors with high elongation aluminum alloy, in aluminum by adding iron and other materials, and pressed through a special process and stranded annealed alloy aluminum voids "squeeze pressure "clean, reducing the cross-sectional area and having good flexibility. Insulating materials with flame-retardant silane-crosslinked polyethylene independent research and development, the outer layer of a metal chain armor structures.
Currently, the use of such technology is developed for the domestic rare cable.
According to experts, the aluminum safety performance is better than copper core cable, when its surface is in contact with air, will form a thin oxide layer of rugged, corrosion-resistant. Because the added iron produces high strength and creep resistance, even after prolonged overload and overheating, but also ensures a stable connection. In addition, the rebound properties of this aaac conductor are 40% smaller than copper cable, and flexible performance is 24% higher than copper cable. Because the weight of aaac conductor is only 50% of copper cables, but also a cost-effective installation.
To achieve the same electrical performance, aaac conductor direct procurement costs 40% lower than copper cables, and general construction and installation of construction costs can save more than 20%. The gradual depletion of copper resources, increasing the demand for cable in, aaac conductor can not only save a lot of investment but to create a conservation-oriented society will also have an invaluable role.
