The SIHF-JB 3G0.75 from böhm Kabel is a heat-resistant silicone hose cable designed as a movable connection cable for devices in environments with high temperatures. It is particularly used in the metallurgical, steel, and rolling mill industry, in packaging machinery, in 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 control technology due to its thermal resistance. The cable features a tinned copper stranded conductor of class 5 as the conductor, insulated with silicone rubber. The sheath is also made of silicone rubber and is finished in a reddish-brown colour. The core identification follows VDE 0293-308, with black cores numbered from six cores onwards and the protective conductor marked green-yellow.

Applications
This cable is designed for applications where high ambient temperatures occur. It is suitable for movable connections in industrial machines and plants, where mechanical stress and thermal load occur simultaneously. Its fields of application range from metalworking industry to packaging technology and extend to plants in the glass and ceramic industry. It is also used in thermal technology, for example in saunas or heating systems, due to its heat resistance.

Functions and Equipment in Detail
The SIHF-JB 3G0.75 is characterised by its high thermal resistance. It is halogen-free, heat-resistant, and cold-flexible, making it suitable for operating conditions over a wide temperature range. Its good weather resistance also allows outdoor use. The cable is flame-retardant and self-extinguishing, according to test method B (IEC 332-1), which increases safety in the event of fire hazards. The core insulation and sheath made of silicone rubber ensure high mechanical and chemical resistance.

Technology Explained Simply
The rated voltage is 300/500 V, which is sufficient for most industrial applications. The test voltage of 2000 V ensures electrical strength. The temperature range extends from -25 °C to +180 °C for moving use, from -40 °C to +180 °C for stationary use, and up to +250 °C for short-term use. The minimum bending radius is 6 times the cable diameter for free installation and 12 times for flexible use, taking into account mechanical stress under movement. The silicone insulation ensures high flexibility at low temperatures and stable performance at high temperatures.

Compatibility and Accessories
The cable is designed for use in industrial machines and plants, where it can be combined with appropriate connectors, cable lugs, or cable glands. The core identification according to VDE 0293-308 enables clear assignment of cores, especially in multi-core applications. The reddish-brown colour of the sheath is typical for silicone cables and supports visual identification.

Installation and Mounting
Installation is carried out in movable connection cables, with the bending radius for flexible use limited to 12 times the cable diameter. The cable is designed for free installation, taking into account mechanical stress from bending and pulling. Connection techniques use suitable cable lugs or connectors designed for the rated voltage and cross-section.

Advantages in Operation
The cable offers high thermal and mechanical load capacity, extending its service life in demanding environments. The halogen-free composition reduces the formation of toxic gases in the event of fire. Cold flexibility allows use at low temperatures without the cable becoming brittle. Self-extinguishing and flame-retardant properties increase operational safety. Good weather resistance also makes the cable suitable for outdoor applications.
