Additional properties of natural esters and nanoesters for industrial use

Abstract

Along with the fact that organic esters are increasingly used in electrotechnical devices as electrical insulation and cooling element, additional requirements for improving their performance are also growing. Several studies in the past have already demonstrated the dielectric properties of these liquids, but also other advantages such as nonflammabilityor biological degradability and renewability. However, problems with electrical strength at very high voltages associated with space charge, higher viscosity, lower oxidation stability, not yet know compatibility issue with technological parts of electrical devices such as seals or sedimentation of nanoparticles need to be further studied. In this article is addressed the compatibility test and modification by nanoparticles of titanium and silicon dioxide.
