Effect of Filler Materials in Silicone Rubber for the Electrical Insulation Applications: A Review

The chief focus of manufacturers over a diversification of industries is on eco-friendly materials. It is aimed at manufacturing electrical and electronic appliances. These material solutions are required to refine the insulators' performance and functionality as they become progressively smaller, lighter in weight, and more reliable. Silicone rubber is an excellent insulator for high-voltage equipment, transformers, and other electrical components. Silicone rubber not only steadily sustains its electrical properties while subjected to environmental conditions such as moisture and temperature fluctuations, but it is also safer and cleaner than its competitors. This review mainly focuses on the mechanical, thermal, electrical, and chemical properties of incorporating various fillers into a silicone rubber matrix for recommended electrical insulation applications.
