The silicone hose cable SIHF-JB 5G10 from böhm Kabel is a heat-resistant cable for movable connection applications in technical installations exposed to high thermal loads. It is particularly suitable for applications such as metallurgical, steel, and rolling mill technology, packaging machinery construction, safety technology, control, measurement, and regulation technology, as well as cement, glass, and ceramic processing. It is also used in sauna construction and in heating, cooling, and climate technology due to its thermal resistance. The cable is designed for use in environments with high temperatures, and is also durable under movement and flexible use.

Applications

The cable is designed for movable connection lines used in industrial and technical installations where high ambient temperatures occur. It is used, for example, in metalworking, machine construction, and process automation, where high mechanical and thermal load capacity is required. The application areas also include thermal technology, particularly in saunas, as well as in the glass and ceramic industry, where high temperatures and mechanical stress occur simultaneously.

Functions and Equipment in Detail

The cable consists of tinned copper strands of class 5, ensuring high flexibility and mechanical load capacity. The conductors are insulated with silicone rubber, providing high heat resistance and chemical resistance. Conductor identification follows VDE 0293-308; from six conductors, the black conductors are numbered, with the protective conductor marked green-yellow. The sheath is also made of silicone rubber and is coloured reddish-brown. This material combination ensures high mechanical strength and thermal stability.

Technology Explained Simply

The cable is rated for a nominal voltage of 300/500 V and has a test voltage of 2000 V, ensuring high electrical insulation performance. The temperature range is -25 °C to +180 °C for movable use, and -40 °C to +180 °C for non-movable use, with short-term temperatures up to +250 °C permitted. The minimum bending radius is 6 times the cable diameter for free installation and 12 times for flexible use, ensuring mechanical durability under movement. The burning behaviour corresponds to test type B (IEC 332-1), indicating flame-retardant and self-extinguishing properties. The cable is halogen-free, heat-resistant, and cold-flexible, making it suitable for use in harsh environments.

Compatibility and Accessories

The cable is designed for use in industrial and technical installations where high thermal and mechanical loads occur. It is compatible with standard connection terminals and plug connectors rated for a nominal voltage of 300/500 V. Conductor identification according to VDE 0293-308 enables clear assignment of conductors, especially in multi-conductor applications. The standard reddish-brown colour of the sheath serves visual identification.

Installation and Mounting

The cable can be installed in movable and non-movable systems. For movable use, a bending radius of at least 12 times the cable diameter must be maintained; for free installation, the minimum bending radius is 6 times. Installation follows standard procedures for flexible cables, taking into account mechanical and thermal loads. The cable is suitable for indoor and outdoor use, with good weather resistance ensuring long-term functionality even under moisture and UV radiation exposure.

Operational Advantages

The cable is characterised by its high heat resistance and mechanical flexibility. The use of silicone rubber for insulation and sheathing ensures high chemical resistance and weather resistance. The halogen-free composition reduces the formation of toxic smoke gases in case of fire. The combination of cold-flexible and heat-resistant properties enables use over a wide temperature range, expanding application possibilities. The self-extinguishing and flame-retardant properties increase operational safety.
