Paper Title - Perfection Characteristics of Nano Materials for Electrical Insulators
Insulating materials play a vital role in the design and performance of electrical power systems for both steady state
and transient state conditions. The last decade has witnessed significant developments in the area of nano dielectric materials.
Significant effects of nano scale fillers on electric, thermal and mechanical properties of polymeric materials have been
observed. The electrical and mechanical properties are more important for the insulating materials used in high voltage
applications. The present review article represents a comprehensive study on polymer nano materials that are used in high
voltage insulation. The study goals are to determine the impact of filler size, type and distribution of the particles into the
polymer matrix on the electrical and mechanical properties of the polyester nano materials compared to the neat polymer and
traditionally materials used as insulation systems in high voltage engineering. Experimental results showed that the nano
materials [polyester loaded with nano titanium dioxide (TiO2) and nano silicon dioxide (SiO2)] improved the electrical and
mechanical properties compared with the standard polymeric materials, and concluded that, the nano materials polyeste r
loaded with 5% nano SiO2 give the insulating materials the ability to be used for heavy electrical applications in dry and
various coastal environmental pollutions. Mechanical properties were also studied and described in this paper. The composite
materials with polyester properties were mechanically evaluated by conducting the mechanical tests which include
compressive and tensile strength. Results of compressive and tensile strength tests confirmed that the best enhancement up to
3% vol. of SiO2 then the strength decreases.
