    Nanostructures in the Formation of the Properties of High-Current Sliding Electrical Contacts on the Electric Rolling Stock
    (Igor Sikorsky Kyiv Polytechnic Institute, 2019) Ustymenko, Dmytro V.; Mukha, Andrii M.; Baliichuk, Oleksii Yu.; Kurylenko, Olena Ya.; Romanov, Serhii; Sabiev, Tamerlan
    ENG: The paper presents the results of bench tests of wear resistance of contact inserts of current collector runners made of «ROMANIT-UVLSh» material and their effect on the wear of the copper contact wire is evaluated. This material is a composite with a high content of electrically conductive lubricants capable of forming a thin conductive transition layer in a friction pair. Low temperature in the contact zone, indirectly, indicates a low transition resistance and high energy performance of the sliding contact, and low wear of the contact wire confirms its high tribological and mechanical properties. The use of contact inserts runner’s current collectors made from this material is possible, both in alternating and direct current and can provide higher technical and economic indicators in comparison with traditional materials.
