  This paper focuses on the behavior of conduction particles motion in the insulating (Sulphurhexafluoride) SF6 gas under the impulse voltage. These conducting particles play an important part on the reduction of the dielectric strength of the SF6. The drag force based on the viscosity of insulating gas is taken into account. The effect of the particle shape, configuration of the gap, atmospheric conditions and the dimensions of the contamination particles are investigated. The software program is carried out to simulate the motion of the contamination particles in insulating gas.
