PRODUCT DESCRIPTION

SiHF is a flexible, heat-resistant silicone rubber cable with finely stranded Class 5 tinned copper conductors, silicone rubber core insulation and a silicone rubber outer sheath. Designed for connections to movable electrical equipment under low mechanical stress, especially in industrial environments exposed to high temperatures or cold conditions. The insulation and sheath are resistant to oils, greases, acids, alkalis and oxidising agents. Available as SiHF-J with a protective conductor and SiHF-O without a protective conductor. Rated voltage: 300/500 V. Maximum permissible conductor temperature: +180°C.
