The current research aims to study the influence of loading of aluminum oxide (Al2O3) and titanium dioxide (TiO2) nanoparticles on the mechanical, electrical, dielectric, thermal and dielectric breakdown strength properties of high density polyethylene (HDPE) specially used for the main insulation in power cables. The HDPE/Al2O3 and HDPE/TiO2 nanocomposites were prepared by melt blending technique with different ratios of nanoparticles. A modifier was used to reduce the agglomeration of TiO2 and Al2O3 nanoparticles inside the HDPE matrix. There are improvement in tensile strength (35% and 47.2%), tensile modulus (37.9% and 40.8%), flexural strength (18.8% and 23.1%), flexural modulus (11.2% and 12.4%), impact strength (11.8% and 13.9%), electrical conductivity (102 and 104), dielectric constant (80% and 224%), dielectric breakdown strength (35% and 41%), thermal stability (43°C and 34°C), melting point (5.5°C and 5.9°C), hardness (7.3% and 9.4%), and crystallization temperature (3.3°C and 4.2°C) of HDPE/Al2O3 and HDPE/TiO2 nanocomposites, respectively, after certain loading of both fillers compared to neat HDPE. The elongation at break and crystallinity were reduced after the addition of both nanofillers within the HDPE matrix. Except thermal stability, the titania based nanocomposites exhibited good performance compared to alumina based nanocomposites. Overall, this substantial improvement in results showed that both composites can be used for high voltage cable application.

Partial discharges occur the biggest failure problem in power cable insulation due to distortion of electrical stress. In this paper, it has been investigated on the effect of spherical nanoparticles of Barium titanate (BaTiO3) and Clay for enhancing electrostatic field distribution in single and three-core power cables. It has been applied new strategies of nanotechnology techniques for designing innovative polyvinyl chloride insulation materials by using nanocomposites and multi-nanocomposites. Moreover, it has been studied the electrostatic field distribution within power cable nanocomposites insulation in presence of air voids, water voids and cupper impurity voids. The electrostatic field distribution in power cable insulation has been calculated by finite element method (FEM). A comparative study has been investigated on the effect of nanocomposite insulation for enhancing electric field stress in power cables.
