Production Quality of Steel Core Aluminium Strand Wire

The galvanized steel wire for steel-cored aluminum stranded wire is an important metal material for the cable reinforcing core, and is mainly used for long-distance overhead transmission lines of the electric power industry. In recent years, the demand for this product in China has increased. 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.

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 enterprises do not use water-cooled steel wire after the zinc pot, the thickness of iron-zinc alloy is thick, which affects the service life of galvanized steel wire. Many factories do not have a clear understanding of the welding joint problem. Some companies are welding after breaking one line, do not carry out the technical parameter table of steel core aluminum strands, and some enterprises do not cool the drawing die in the drawing process. This also has a greater impact on product quality.

Some factories pay insufficient attention to the quality of testing products, and the testing items are incomplete. Errors in error judgments occur frequently; some enterprises pay insufficient attention to product packaging, do not pack according to the standard, damage the inner and outer packaging, expose the steel wire, and the items on the sign are incomplete. , the number of bundles is too small, and so on.
