With a continual progress in polymer nanocomposites, this
research depicts the effects of types and concentration of costless
nanoparticles in electrical properties of power cables insulation
materials. Also, the current research focus on the electric break-
down failure of low and high polyethylene as a matrix base for var-
ious costless nanoparticles added (clay, and fumed silica). All
experimental results have been investigated and discussed to
detect all effects of nanofillers on electrical properties of nanocom-
posite Polyethylene (PE) power cables materials.
