“…Polyvinyl Chloride (PVC) is the most widely used of any of cables, thermoplastics, polymerized vinyl chloride and is produced from ethylene and anhydrous hydrochloric acid. PVC is stronger and more rigid than other general-purpose thermoplastic materials, tough, strong, resist water, abrasion, and are excellent electrical insulators [16]. Clay nanoparticles are used to reduce the density of product [17].…”

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.

“…Quite wide classes of guest components, such as ions, atoms, molecules, and complex molecular clusters are well known today. They could exist in between quantum layers of matrices in 3 main phases lattice gas [1,2], quasiliquid [3,4], and solid phase [5][6][7][8]. But the 4th type of phase, the quasiplasma state of the encapsulated guest component, has been not investigated yet and it could be a field for wide spectrum of novel properties and, as a consequence, novel application ideas.…”

The current work represents results for the encapsulation of 1-Allyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ionic liquid (IL) in the cavities of the SBA-15 mesoporous dielectric matrix for the first time to our knowledge. Obtained SBA-15<IL> clathrate is a structure with a nanodimensional phase of IL matrix-ordered and isolated by dielectric SiO2. The character of frequency dependent impedance, loss tangent, and dielectric constant for obtained clathrate was investigated under normal conditions, under illumination, and in constant magnetic field. Current-voltage characterisation revealed the capacitive properties of the obtained nanohybrid structure and Cole-Cole diagrams confirmed the Jonscher mechanism of charge relaxation in it. The conditions of the synthesised SBA-15<IL> accumulating the electric energy at a quantum level were determined. The results presented in this work are unique and they prove that the synthesised substance is promising for application in quantum accumulators.

The solid-state transformer (SST) in the renewable energy grid is developing in the way of high voltage and high frequency, which often results in a sharp increase in heat production of the equipment and accelerates the failure of the insulating materials. Epoxy resin (EPR) is commonly used as an insulation material for SST due to its excellent electrical insulating properties, processing performance (viscosity), and low price. However, the thermal conductivity of EPR is only about 0.2 W/(m·K), which leads to poor insulating performance under high frequency and temperature. To enhance thermal conductivity, a substantial quantity of highly thermally conductive particles is incorporated into the EPR, accompanied by a severe increase in electrical insulation defects and viscosity. This study utilized a multi-scale particle-filled approach to investigate the thermal conductivity, processing characteristics, and high-frequency electrical insulation performance of composites. The composite, filled with 25 µm BN and 5 µm SiO2 particles, enhances thermal conductivity to 0.732 W/(m·K) and demonstrates superior electrical insulating properties at both 10 kHz and 20 kHz bipolar square waves (with an increase of 131.76% and 163.97% in relative EPR, respectively), as well as good processability. Meanwhile, it is found that the dielectric loss, thermal conductivity, and electric field distribution of the composite are the main factors affecting the electrical insulating properties from 10 to 20 kHz under high voltage.
