Prospects for manufacturing electrical investigated products based on modified copper oxide (I) a novolac resin. It is shown that copper oxide modification improves the physico-mechanical, tribological, electrical properties, resistance to mechanical wear and oxidation products of the materials. Introduction of coke in the material increases its durability when operating on the worn contact network. Trial runs have shown a trolley parks that the contact insertion trolley manufactured using a modified copper oxide (I) novolak binder in performance on average 2-4 times higher than the commercial materials of different manufacturers
