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.
