Product Overview
Specially engineered for extreme temperature environments, the H05SS-F and H05SST-F silicone rubber cables deliver reliable performance up to 180°C. Featuring flexible silicone rubber insulation and sheath, these multicore cables withstand thermal stress, mechanical shock, and chemical exposure in industrial settings. The H05SST-F variant includes polyester fiber braiding for enhanced mechanical protection.
