Spatial distributions of mass and current inside current-driven wire array during implosion were investigated on Angara-5-1 facility. Radiography of dense cores of imploding wire array, measurements of internal azimuthal magnetic field in wire array and electron density measurements on the periphery of initial array position at the moment of stagnation give new experimental evidences of prolonged plasma production phenomenon. The measurement of current density inside the array shows that about half the current flows on the liner periphery at the moment of maximum compression. At this time up to 10% of the liner mass is present on the periphery of the initial wire array.
