Production Quality of Steel Core Aluminum Stranded Wire

The galvanized steel wire for steel-core aluminum stranded wire is an important metal material for the cable reinforcing core, which is mainly used in the long-distance overhead transmission line of the electric power industry. Since the cable has been listed as an important electromechanical product, at the same time, in order to increase the span of the cable erection and prolong the service life, the power industry has put forward higher and higher requirements on the quality of the cable. As the galvanized steel wire of the cable core, The quality of its quality will directly affect the quality of the cable. After 30 years of hard work in China, galvanized steel wire for steel-cored aluminum stranded wire has been improved in both production and quality.

Some factories are not able to strictly enforce the operating procedures. The surface treatment of the steel wire before galvanizing is poor, which affects the firmness of the zinc layer and reduces the winding performance. A few companies do not use water cooling after the steel wire is out of the zinc pot. The thickness of the iron-zinc alloy affects the service life of the galvanized steel wire. Many factories do not know the problem of welding joints clearly. Some enterprises cut off the wire after drawing, and do not implement the technical parameter table of steel-cored aluminum strands. Some enterprises do not cool the wire drawing die during drawing, which has a great impact on the quality of the products.
