Analysis of foreign trade operations of the Russian Federation cable market
The paper is devoted to the analysis of foreign trade operations of the Russian Federation cable market and discloses the problems associated with the import substitution of cable products. Import substitution has been effectively commenced (in 2015 the import of cable products to the RF decreased by 49, 6 %). An important task of expansion of domestic cable export was set.

Study into the feasibility of optical cable application under the exposure to ionizing radiation
The paper presents the results of the investigation of ionizing radiation pulse action on optical fibers of different types and from various manufacturers. The dependence of radiation- induced attenuation on the exposure dose of gamma rays is shown for different specimens of optical fibers and cables. The obtained results suggest the conclusion that standard optical fibers retain their operational capability after pulse action of ionizing radiation and optical cables with special fibers can be operated under long-term exposure to gamma radiation.

Influence of the vulcanizing group content on the properties of ethylene-propylene rubber based compounds for cable sheaths
The authors investigated the influence of the vulcanizing group content on the properties of ethylene-propylene rubber compounds. Technological and performance properties of compounds were studied. All the investigated rubber compounds can be used as cable sheathing materials according to their application with the cost of ingredients taken into account. It was established that rubbers with peroxide vulcanizing group with trimethylolpropane-trimethylacrylate co-agent had the highest resistance to thermal ageing.
