FIELD: electricity.
SUBSTANCE: current-transmitting surface of dismountable contact connection (DCC) is cleaned and degreased. After application of liquid flux the surface is heated up to a temperature of 65-70°C. After mechanical treatment and removal of flux excess bismuth-based alloy with melting temperature of 47-60°C and thickness less than 0.1 mm is applied to the current-transmitting surface. In result of contact hybrid melting the coating is formed. In 3-4 minutes after application of the alloy to the current-transmitting surfaces they are cooled up to a temperature of 40°C.
EFFECT: reduction of transient electric resistance for DCC, stabilisation of its value at the level of initial assembly within the whole period of its service life, expansion of the scope of DCC efficient application.
