Multiple enhancement of PVC cable insulation using functionalized SiO 2 nanoparticles based nanocomposites

Recent Advances in Polymer Nanocomposites Based on Polyethylene and Polyvinylchloride for Power Cables

“…Figure 8 shows some results for PVC/TiO 2 nanocomposites, with and without vinyl silane-based surface modification of the TiO 2 nanoparticles [ 60 ]. Similar decreases in dielectric loss following the addition of SiO 2 nanocomposites functionalized by amino silane to PVC have been observed [ 64 ], but only at frequencies below 1 kHz. LDPE/MgO nanocomposites also exhibited a lower dielectric loss than either base LDPE or LDPE microcomposites [ 94 ].…”

“…Many experimental studies of the breakdown strength of nanocomposites have been reported [ 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 ]. In most cases, the measurements were carried out under a uniform electric field or semi-uniform electric field using sphere-to-sphere electrode or sphere-to-plane electrode, respectively, as shown in Figure 3 .…”

Surface‐modification effect of MgO nanoparticles on the electrical properties of polypropylene nanocomposite

“…Polymeric composite materials have been extensively applied in electrical insulation [1][2][3][4][5][6]. As the polymeric matrix, low-density polyethylene (LDPE) and cross-linked polyethylene (XLPE) were widely used in high-voltage direct current (HVDC) cable insulation because of their low permittivity and dielectric loss, high resistivity, decent mechanical flexibility and low cost [7][8][9][10].…”

Enhancing the High Voltage XLPE Cable Insulation Characteristics Using Functionalized TiO<sub>2</sub> Nanoparticles

“…One method for enhancing polymeric insulators behavior is using the concept of composite, inorganic particles were incorporated inside polymer matrix to produce what is called polymer composites [6,7]. In the previous decade, the design of composite materials involving either micro-scaled or nanoscaled inorganic and inorganic particles has gained great attention at power engineering to improve the properties of insulators dielectric, mechanical, and thermal [8][9][10][11][12][13][14][15][16][17][18][19]. The polymer composites were identified by their low working temperature, sensitivity to moisture and radiation also they have a high thermal expansion coefficient [20].…”
