An additional mechanism of electroconductive channel evolution due to electronic heat conductivity in nonequilibrium plasma is considered in the work. Two-temperature models of stationary arcs are considered, the condition of the models application to simulating the arc phase of a spark discharge is validated. The given condition is based on ionization equilibrium time estimation. A mathematical model of electroconductive region expansion through mechanism of electronic heat conductivity is presented. Influence of the gas-discharge medium pressure, the plasma heavy component temperature gradient, the electric field strength on the electroconductive region evolution dynamics is investigated.
