The silicone hose cable SIHF-JB 5G2,5 from böhm Kabel is a heat-resistant cable for movable connection applications in environments with high temperatures. It is used in industries such as metallurgy, steel and rolling mill technology, packaging machinery, safety technology, control, measurement and regulation technology, as well as in cement, glass and ceramic processing. It is also suitable for use in sauna construction and in heating, cooling and climate technology due to its thermal resistance. The cable is characterised by its high flexibility and mechanical durability, making it designed for dynamic operating conditions.

Applications
This cable is intended for applications where high ambient temperatures occur. It is particularly suitable for movable connections, such as those found in industrial machines, heating systems or process automation. Its applications range from metalworking industries to glass and ceramic production, and extend to food processing plants where high temperatures and mechanical stress occur simultaneously.

Functions and equipment in detail
The cable consists of tinned copper strands of category 5, ensuring high flexibility and longevity. The conductors are insulated with silicone rubber, providing high heat resistance and chemical resistance. Conductor identification follows VDE 0293-308; from six conductors onwards, black conductors are numbered, with the protective conductor marked green-yellow. The sheath is also made of silicone rubber and is coloured reddish-brown, enabling good visibility and identification.

Technology explained simply
The silicone hose 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 moving applications and -40 °C to +180 °C for stationary applications. The cable can withstand temperatures up to +250 °C for short periods, making it suitable for extreme thermal loads. 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 method B according to IEC 332-1, indicating flame-retardant and self-extinguishing properties. The cable is halogen-free, meaning lower smoke and gas emission in case of fire.

Compatibility and accessories
The cable is designed for use in industrial plants where high thermal and mechanical loads occur. It can be combined with suitable connectors, cable lugs and protective conduits designed for silicone cables. Using accessories not specifically designed for silicone materials may lead to premature ageing or failure.

Installation and mounting
During installation, the specified bending radii must be observed to ensure the cable's service life. For movable installation, a bending radius of 12 times the cable diameter must be maintained. The cable should not be excessively loaded or kinked to avoid mechanical damage. The connection technique must meet the requirements of the specific application, especially under high temperatures.

Advantages in operation
The cable offers high thermal resistance, is cold-flexible, and has good weather resistance. Its halogen-free composition reduces the formation of toxic gases in case of fire. The silicone insulation ensures high mechanical and chemical resistance, extending service life in demanding environments. The combination of flexibility and heat resistance makes the cable a reliable solution for movable connections in high-temperature environments.
