Abstract

Application is examined liquid-metal and composition materials, as one of methods decline of losses of electric energy in high-current connections. As a result of interfusion of intermetallic powder of FеGа4 with an eutecticum alloy Ga-In-Sn, electroconductive appears heat-resistant plastic material, possessing stability of the homogeneous state in the wide interval of temperatures and enhanceable viscidity. It is shown that application of the worked out plastic electroconductive material on the basis of eutecticum alloy allows: substantially to reduce transitional resistance in pin pair copper-copper, copper-steel, steel-graphite; to promote reliability and productivity of work of electrolysis equipment; due to the decline of power failure on pin transitions to provide the economy of electric power.
