The article deals with the issues of improving the reliability of cable operation and conductor products, due to its quality improvement. Research work was carried out on the example of a МF-100-grade contact wire, which is used in the operation of electrified railway and urban transport in the Republic of Uzbekistan and in other countries. The solution of the issue of improving reliability in the operation of the above-mentioned wire is reduced to improving the manufacturing technology, as well as making changes to the method of calculating the drawing route. The result of the work is the improvement of the performance parameters of the contact wire. Improving the quality of the contact lead is not the only advantage of this method; when replacing the number of wolves from 5 to 3 passes, it led to significant savings in the production process, and also made it possible to increase the reliability of the wire by an average of 1.2%.
