Research of the metal wire electrical disruption conducted. Calculations were carried out in the scope of the molecular dynamic method. Interatomic potentials were described in terms of embedded atom method. It was shown that electrical pulse dispersion process had characteristic stages, which had 3 phases. The influence of heat loading rate on dynamics of metal wire dispersion was investigated. It was revealed that heating rate increase leads to the decrease of average cluster size and increase cluster number. It was shown that the following investigation of metal wire dispersion based on molecular dynamics requires taking into account technological parameters and environmental properties.
