Examining and Comparing the Signal of Ceramic and Silicon Insulators in Medium Pressure Voltage

Abstract

The review article discusses the use of ceramic and silicone rubber (SiR) insulators in high voltage (HV) applications over the past thirty years. It highlights the need for detailed characterization and aging analysis to enhance the long-term performance of SiR insulators under various environmental, mechanical, and electrical stresses. The article focuses on silicon applications, the chemistry and polymerization of SiR, and the enhancement of their properties through fillers and ceramic materials. It also covers engineering requirements for polymer insulants and provides an overview of HV electrical insulators and their aging processes. The influence of micro/nano-sized fillers on the physical, thermal, mechanical, and electrical properties of SiR insulators is analyzed, including aspects like tensile strength, thermal degradation, and dielectric strength. The article concludes that further research is necessary to optimize SiR blends with fillers for specific applications.
