The role of silicone rubber in electrical accessories

The role of silicone rubber in electrical accessories mainly includes insulation, high temperature resistance, fire resistance and aging resistance. Silicone rubber is a synthetic elastomer made by heating and pressurizing linear polysiloxane and reinforcing fillers to vulcanize. It has excellent electrical insulation properties, especially when the temperature and frequency change or when it is damp. Its electrical properties are slightly affected, and its corona and arc resistance are particularly excellent. In addition, silicone rubber also has high heat resistance and cold resistance, excellent fire resistance and insulation, and can maintain the integrity and reliability of transmission lines under direct flame combustion conditions.
