Experiment § Medium- and Low-Voltage Cold-Shrink Silicone Cable Insulation Components We have developed FX301-14, an electrical-grade liquid silicone rubber (LSR) for insulation applications. This product is a two-component, dark gray, paste-like, tear-resistant LSR, specifically designed for injection molding (Fig 1,2). It offers excellent resistance to yellowing, outstanding elastic recovery, superior thermal aging resistance, and ease of processing. In power system applications, FX301-14...
