Product Overview
SIAF and SIAF-GL series silicone rubber cables deliver exceptional thermal resilience (-60°C to +180°C) for extreme environments. Featuring tinned copper conductors and halogen-free insulation, they maintain flexibility in critical applications like steel mills, power plants, and industrial ovens. The SIAF-GL variant adds glass fiber braiding for enhanced mechanical protection where conduit isn't feasible.
