Poly Aryl Ether Ketone based Novel nano composites as dielectric material for power equipment

Power Sector and its need for superior dielectric material is ever growing. In India exponential growth in the installed capacity is expected. During the 12^th 5 year plan period it is expected to touch 3 GW installed capacity. Proposals are on the anvil go in for very high voltage transmission system (1200 kV) and very high voltage Director current system (HVDC) to meet the requirements of power. HVAC and HVDC systems put special demand on the dielectric material used in these power equipment. Novel polymeric nano composite system has been developed which has shown apart from good dielectric properties, good thermal conductivity characteristics. Nano fillers having 25-35 nm developed in house by combustion synthesis were used. The filler compositions were such that apart from improving the dielectric properties the thermal conductivity characteristics were improved. Inherently superior polymeric matrix based on Poly Aryl Ether Ketone was used in development of the composite dielectric. Dilectric loss Factor, Dielectric strength and Capacitance characteristics showed encouraging results. This insulation is proposed for use in power equipment as novel insulation system in place of conventionally used mineral oil and cellulosic paper based insulation.
