Investigation of the Qualitative Characteristics of Marine Cable Products

A characteristic feature of modern electrotechnical complexes and systems characterized by a large functional diversity is a wide quantitative range of different types of cable products related to their interface devices. The reliability of cables has a direct impact on the quality of functioning of electrical products, the safety of their operation during technical use and maintenance, and in some cases during repairs. It is obvious that increased climatic, mechanical, chemical and other loads worsen the quality characteristics of cables, causing increased scientific and practical interest in the trends of their changes, which have a direct impact on the deadlines for the normal operation of cable products. In such typical operating conditions, marine electrical equipment, in particular, including a large number of its cables, functions, since many vessels can be in various, significantly different climatic conditions at relatively short intervals of operation. The deterioration of the quality characteristics of marine cable products is also influenced by significantly varying mechanical loads, mainly caused by vibration of electrical equipment during operation of the main engines. The projected increase in the degree of electrification of ships, as well as electrical complexes and systems of many other branches of economic and household activity, increases the relevance of the research topic. Based on in-depth data collection and qualitative analysis, studies of the technical condition of shipboard cable products based on the principles of modern statistics have been carried out, the results of which should be used as initial data when building effective models for diagnosing the quality of cable products and predicting its residual service life, preventing premature cable replacement.
