TECHNICAL APPROACH IN EVALUATING OF THE CHARACTERISTICS OF MULTI-CORE BALANCED NONQUADDED CABLES FOR DIGITAL COMMUNICATION SYSTEMS

Abstract

The article proposes a variant of the technical approach in evaluating of the characteristics of multi-core balanced nonquadded cables for digital communication systems.
 The list of modern standards of the International Electrotechnical Commission, and also the National standards of Ukraine and the international standards which are created on their basis is presented. The proposed standards define the general requirements for communication cables, offer verifying methods for the design, structural dimensions, and materials of elements, marking and packaging. In addition, the provisions of these standards define the methods of testing the electrical characteristics, survivability and resistance of the cable to climatic and mechanical factors.
 A list of proposed cable characteristics, i.e. electrical, survivability and resistance to environmental influences, is sufficient to assess the cable for compliance with the stated requirements. The list of considered characteristics is not exhaustive and can be supplemented or changed depending on requirements of the customer.
 On the example of using the automatic measuring system AESA 9500 made in Sweden to measure electrical characteristics, the possibilities of optimizing the process of evaluating the characteristics of the cable through the use of modern automatically controlled measuring systems, which will significantly reduce the time and cost of evaluation are considered.
 The approach presented in the article to the evaluation of the characteristics of multi-core balanced nonquadded cables for digital communication systems can be used during the testing of the cable planned for delivery to the Armed Forces of Ukraine.
