“…The goal of this paper is to analyze the dielectric constant of new multi-nanocomposites that are formed for enhancing electrical insulation of three core belted power cables. In case of using individual nanoparticles inside polymer matrix, power law relationships used in dielectric modeling of composite systems; the composite system have three components (matrix and nanoparticle) and an interphase region [1,2]. Furthermore, the interphase region volume fraction is dependent upon the nanoparticle volume fraction, the nanoparticle surface area and the thickness of the interphase region surrounding each nanoparticle particle [3].…”

This paper presents an investigation on the enhancement of electrical insulations of power cables materials using a new multi-nanoparticles technique. It has been studied the effect of adding specified types and concentrations of nanoparticles to polymeric materials such as PVC for controlling on electric and dielectric performance. Prediction of effective dielectric constant has been done for the new nanocomposites based on Interphase Power Law (IPL) model. The multi-nanoparticles technique has been succeeded for enhancing electric and dielectric performance of power cables insulation compared with adding individual nanoparticles. Finally, it has been investigated on electric field distribution in the new proposed modern insulations for three-phase core belted power cables. This research has focused on studying development of PVC nanocomposite materials performance with electric field distribution superior to the unfilled matrix, and has stressed particularly the effect of filler volume fraction on the electric field distribution.

“…Dielectric spectroscopies in time and frequency domains are useful tools for evaluating and diagnosing electrical insulation and understanding the dynamics of complex solid polymer systems [5][6][7]. Metal oxide nanoparticles in polymers have been studied as alternative materials for electrical applications [8][9][10][11]. Studies have demonstrated that the incorporation of nanoparticles in similar systems can have both positive and negative effects on breakdown strength [12][13][14].…”

Poly-Vinyl Chloride (PVC) is a commonly used material used in cable insulation sheaths, but its dielectric properties can be negatively impacted by electric aging. This study investigates the use of nano-fillers, specifically alumina (Al2O3), titanium dioxide (TiO2), calcium carbonate (CaCO3), and barium titanate (BaTiO), in order to improve the dielectric properties of PVC. Films of PVC were doped with nano-fillers and were then exposed to an alternating voltage of 15kV for various time periods (1, 2, and 3 hours). The dielectric properties of PVC were measured using an impedance analyzer, and the results indicated that the use of these nano-fillers had a positive effect on the dielectric characteristics of PVC.
