\n SiHF \u00b7 HIGH-TEMPERATURE SILICONE RUBBER FLEXIBLE CABLE\n <\/div>\n

SiHF Silicone Rubber Flexible Cable 300\/500 V<\/h2>\n

SiHF<\/strong> is a flexible silicone rubber cable for connecting movable electrical equipment under low mechanical stress and high ambient temperatures. It features finely stranded tinned copper conductors (Class 5), silicone rubber insulation and a silicone rubber outer sheath.<\/p>\n

Suitable for industrial equipment, steelworks and cold environments. The insulation and sheath are resistant to oils, greases, acids, alkalis and oxidising agents. Available as SiHF-J (with protective conductor) and SiHF-O (without protective conductor).<\/p>\n <\/div>\n\n
