Short Review on Silicone Rubber Based Composites as High Voltage Insulation Material

Abstract

Silicone rubber (SiR) was established as one of the most favorable high voltage (HV) insulator for outdoor application. It possesses unlimited advantages such as undeniable heat resistance, lightweight and versatility in outside environment with outstanding electrical insulation behavior. The progress of SiR utilization as HV insulator was continuously advanced since its first establishment, seven decades ago. The manipulation of this functional macromolecules is diversified due to its customizable, manufacturability, easy processing, low-cost and modifiable. Extensive research has been performed all around the globe to discover the potential of SiR for various other applications. In this review, special attention to SiR types, modification using filler addition, SiR based nanocomposites, electrical insulation performance, and related issues on SiR as high voltage insulation materials were emphasized. This is significance to establish a standard guideline to optimize SiR potential for HV application.
