“…Nanosilica/XLPE nanodielectrics, thanks to their improvements in several key dielectric properties, have been suggested as potential candidates for MV and HV power cables (Roy et al, 2007;Roy, 2005;Tanaka et al, 2011). However, silica nano-fillers usually suffer from the aforementioned agglomeration and water-affinity problems, and are thus commonly subjected to surface modifications.…”

Finally, I would like to thank those who can never be thanked enough, my family, for their endless concern, selfless love, and unwavered supports. COMPOSITES À BASE DE POLYÉTHYLÈNE AVEC ADDITIFS DE POLYHEDRAL OLIGOMERIC SILSESQUIOXANES : ISOLATION ÉLECTRIQUE POUR DES CÂBLES DE PUISSANCEMeng GUO Globalement, les résultats expérimentaux indiquent qu'aucune méthode de fabrication n'est efficace pour fabriquer des nanodiélectriques de PE/solide-POSS. Relativement aux propriétés thermiques, l'addition de POSS a pu entraîner une augmentation de la conductivité thermique jusqu'à 8%. De plus, il a été observé que l'ajout de POSS ne modifie pas la stabilité thermique du PE dans une atmosphère d'azote et ne cause que peu de changements dans le comportement de fusion du PE, le comportement de cristallisation du PE et le degré de cristallinité du PE. En ce qui concerne les propriétés diélectriques, tous les composites PE/POSS ont des résistances à l'érosion face aux décharges partielles qui sont bonifiées, s'améliorant de 6% à 61%. Cette amélioration renforce l'isolation envers des dommages cumulatifs provoqués par la dégradation électrique dans les conditions de service. De plus, la présence du POSS n'affecte que peu les réponses diélectriques à la température ambiante : les constantes diélectriques et les pertes diélectriques pour les composites sont, respectivement, 2.25-2.35 et généralement 10 RÉSUMÉ, soit des valeurs semblables aux valeurs associées au PE. Conséquemment, ces valeurs sont encourageantes pour une application dans les câbles, qui nécessitent de faibles pertes et de faibles constantes diélectriques. À des températures élevées, l'influence des POSS sur les réponses diélectriques du PE demeurent faible, excepté pour quelques augmentations des pertes dans PE/IO1 (E) et PE/OM5 (E) à des fréquences plus basses que 10 Hz, et pour des transports de charges (la diffusion et la conduction) renforcées dans PE/IO5 (E). À l'inverse des performances d'amélioration relative à la résistance à l'érosion, l'utilisation des POSS n'améliore presque pas la tension de claquage à court terme du PE; au mieux, les tensions de claquage des composites PE/POSS demeurent semblables à celles du PE.Parmi les trois méthodes employées, le broyage mécanique a été plus efficace pour disperser 5 wt% OibPOSS, la dissolution chimique et l'extrusion ont été plus efficaces pour disperser 1 wt% OibPOSS, et l'extrusion a été plus efficace pour disperser IoPOSS. Il a été observé que les méthodes de fabrication ont peu d'effet sur la conductivité thermique et les réponses diélectriques, excepté lorsque les distributions résultantes sont particulières, comme dans les cas PE/IoPOSS : il semblerait que de l'alignement possible dans le cas PE/IO1 (XSB) et la quasi-connexion possible dans le cas PE/IO5 (E) pourrait expliquer l'augmentation de la conductivité thermique pour PE/IO1 (XSB) et l'intensification du transport de charges pour XI PE/IO5 (E). Cependant, il a été trouvé que la méthode de fabrication avait un effet sur la résistance à l'érosion : l...

“…XLPE-based nanodielectrics containing silica nanoparticles can present improvements in several key dielectric properties over neat XLPE, such as increased dielectric breakdown strength, enhanced voltage endurance, enhanced partial-discharge resistance and reduced space charge accumulation [12][13][14][15][16]. As a result, they have been suggested as a potential insulation material candidate in MV and HV power cables [17].…”

High-energy ball milling was tested as a method for producing Ultra High Molecular Weight Polyethylene (UHMWPE)-based nanodielectrics containing 1 wt% and 5 wt% OctaIsoButylPOSS (OibPOSS). Qualitative and quantitative evaluations were used to explore the compatibility between OibPOSS and PE. Several ball milling variables were optimized in a bid to achieve UHMWPE/OibPOSS nanodielectrics. The morphology, as well as the thermal and the dielectric properties of the samples, were characterized by scanning electron microscopy, thermogravimetric analysis, broadband dielectric spectroscopy, and progressive-stress breakdown tests. The results showed that (i) ball milling was an effective method for producing UHMWPE/OibPOSS dielectric composites, but appeared ineffective in dispersing OibPOSS at the nanoscale, and (ii) the resulting UHMWPE/OibPOSS dielectric composites presented thermal and dielectric properties similar to those of neat UHMWPE.

“…In addition, XLPE is not recyclable and its processing is quite energy intensive and complex. Regarding space charge suppression, or reduction, it has been shown already that space charge injection can be minimized by controlling polymer morphology and crystallinity, and accumulation can be minimized working on charge mobility adding nanoparticles able to create low-energy trapping sites at the nanoparticle surface and on the interaction zones between the nanoparticle and the polymer matrix [3]- [5]. Different space charge accumulation choosing a PP/SiO2 nanocomposite over XLPE could contribute to solve major issues coming from long term or single polarity switching event.…”

Abstract-This paper presents the scientific background of a new European project, GRIDABLE, which was launched at the beginning of 2017 and has to deliver results in manufacturing and characterization of LV-MV capacitors and MV-HV cables for DC application. The innovation is in the development of nanostructured materials based on polypropylene and silica, and the relevant capacitor and cable manufacturing procedures. The initial results regarding the electrical properties of PP-SiO2 materials, which have brought to the proposal of this project, are presented in this paper, focusing on breakdown strength and space charge measurements performed on nanofilled PP films for capacitors.
