Quality control of ACSR cables

Chemical composition control

Black wire surface contains a large amount of aluminum and its elements are inseparable, as also long-term exposure to lead in the air, and easy chemical and biochemical reactions. Therefore, during the selection of the wire must strictly control the content of its various chemical components in the production process to ensure the quality of the wire based on rational allocation of its chemical composition, which can improve lead quality to some extent.

Temperature Control

Aluminum elements are a very active metal element, it is easy to react chemically with oxygen in the air element. If the temperature inside the holding furnace is too high, it will accelerate the reaction of aluminum and oxygen, thereby generating aluminum oxide, having a serious impact on the quality of the wire. Too high a temperature will result in the holding furnace water being decomposed into hydrogen and oxygen, wherein oxygen is adsorbed, chemically react with aluminum at high-temperature catalysis to produce alumina, which seriously reduces the tension of the wire, the impact the normal use of wires.

Production process control

Aluminum scrap is immediately removed, ensure lubricating oil in the process of drawing fully into the work area to ensure roundness and surface smoothness of the wire, to avoid scratches, scratches, etc. generated in the production process, should be strictly optimized wire production process to ensure quality leads.

Environment Control

Activity so that elemental aluminum is very vulnerable to external factors or microorganisms such as atmospheric oxidation, resulting in the wire surface being black, largely affecting the use of effects and properties of the wire. Thus, the control wire environment is particularly important, which is to ensure the use of functional life and lead to a strong guarantee.

The optimization of the production process and selection of ACSR cable overcomes many of the shortcomings of its own, so in practice more and more popular. We deal with future problems encountered in everyday use, to sum up, and as a basis for a more in-depth study of how to produce and use good ACSR cable to further improve its performance, and expand its use.
