The effect of polarity on implosion of wire liners on the Angara-5-1 facility has been investigated. The electrode configuration provided creation of a radial electric field of up to 5000 kV/cm and of different direction on various sections of initial wires. The plasma production process was found to proceed in a distinctive manner in the wire sections where the radial electric field has different direction. The polarity effect at implosion of the wire liners on the Angara-5-1 facility becomes notable at increasing the rate of rising the electric field strength.
