 Different from the traditional copper cable, aluminum cable aluminum alloy material with high elongation, by joining in pure aluminum, iron and other materials, and compact-stranded craft and special annealing pr ocessing, the gap "in the aluminum alloy extrusion pressure "clean, reducing the cross-sectional area and has good flexibility; insulating materials using self-developed flame-retardant silane cross-linked polyethylene outer layer of the metal chain armored structure.

Cables for domestic use of such technology developed rare.steel cable clamps

According to experts, the aluminum alloy safety performance is better than copper cable, when the surface in contact with air, will form a thin, solid oxide, corrosion-resistant. Added to iron to produce high strength creep properties, even in a long time overload and overheating, but also to ensure that the connection stable. In addition, this aluminum cable rebound performance than copper cable is 40% smaller, flexible performance 24% higher than the copper cables. Because the weight of aluminum cable, only 50% of the copper cable, but also effectively reduce the cost of installation.steel clip

Achieve the same electrical properties, aluminum cable direct procurement costs 40% lower than the copper cables, general construction and installation of construction cost savings of more than 20%. Aluminum cable in copper resources are gradually depleted, cable demand is constantly increasing, not only can save a lot of investment will also have an invaluable role to create a conservation-minded society.metal cable clamp
