This work aims to investigate the density and microstructure impact on DC performance of pure polyethylene. Plaques of PE-based materials, characterized by different densities namely LLDPE, LDPE and HDPE were investigated through DC electrical tests. These latter include space charge and conductivity tests performed at high electric fields (40 and 20 kV / mm, respectively). Results show that electrical properties decrease as material density increases, defining a dependance between the microstructural arrangement within the polymer matrix and the conduction properties of the insulation system.
