FIELD: railway transport. SUBSTANCE: device has flexible steel-copper conductor forming an open ring in vertical in place of connection to rail. Head of conical connecting pin is provided with slot in which conductor divided into several strands is placed and welded. Pin in place of contact with rail has copper belt and additional cylindrical bushing with conical hole. Steel bus is found from other side of conductor. Contact surface of bus is covered with layer of corrosion- resistant metal featuring higher thermal expansion coefficient than that of steel, for instance, copper. EFFECT: enhanced reliability of energy transmission from choke-transformed to rails. 4 cl, 5 dwg
