In the past, ceramic materials were exclusively used as transmission insulators for high voltage. However, due to the drawbacks of ceramic materials, including their heavy weight, challenging production, and poor toughness, high-voltage transmission insulators are now being replaced by polymeric materials. The majority of the issues with ceramic insulators are addressed by polymeric insulators. This study aimed to enhance the toughness and insulating properties of an epoxy composite developed SiO2 nanoparticles obtained from rice husk. The samples were produced by the solution stir cast method. The microstructure, impact strength, fracture toughness, and insulation properties of the developed composite were determined. The toughness and insulating properties that have been reported are within the acceptable range for high-voltage insulators. The developed composite insulator was found to be capable of withstanding voltages of up to 14.9 kV. The developed composite might be utilized to produce electrical insulators with great toughness and good insulating properties.
