The operation of conductors and contact connections in electric circuits transmitting megaampere-current pulses with durations of tens of microseconds is considered. The permissible conductor-current density is determined from the condition of thermal stability of the high-voltage polymeric insulation. Operating conditions of demountable contact connections for megaampere pulse currents are described, and design examples of such connections operating at a linear current density as high as 80 kA/cm are given. Methods for providing mechanical stability against the action of electrodynamic forces that occur during the passage of megaampere-current pulses are considered.
