Abstract
Abstract The temperature dependence of dielectric processes was investigated of PVC cable insulation. For the investigation voltage response measurement was used, since this method ensures the independent investigation of conductive and polarisation processes. From the results of the measurement activation energies have been calculated to conductivity and polarisation conductivity of the material, the results are in 105.4 kJ/mol…133.8 kJ/mol and 32.1 kJ/mol…51.8 kJ/mol ranges, respectively. These results suggest that different charge carrier distribution mechanisms act main role in dc conductivity and slow polarisation processes in PVC cable insulating material.
