Böhm Kabel 907009 3x1.0 mm² silicone hose cable content_copy

The silicone hose cable SIHF-JB 3G1,0 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 control technology due to its thermal resistance. The cable features a robust construction with tinned copper strands of class 5 as conductors, ensuring high flexibility and mechanical durability. The core insulation and sheath are made of silicone rubber, a material that is both heat- and cold-resistant and offers high weather resistance. The sheath color is reddish-brown, ensuring good visibility and identification during use.

Applications

The cable is designed for applications where the ambient temperature is elevated for extended periods. It is particularly suitable for movable connections, for example in machines with moving parts, in industrial processes with high thermal loads, or in plants operated outdoors. Its applications range from metalworking industries and packaging technology to installations in the food and chemical industries, where high temperatures and mechanical stresses occur.

Functions and Equipment in Detail

The cable is equipped with core identification according to VDE 0293-308. For more than five cores, the black cores are numbered, and the protective conductor is marked green-yellow, enabling clear identification of conductors during wiring. The use of silicone rubber for insulation and sheath ensures high chemical resistance against oils, fats and other industrial chemicals. The cable is halogen-free, meaning that in the event of fire, the smoke gases have lower toxicity, increasing safety during use.

Technology Explained Simply

The rated voltage is 300/500 V, indicating the maximum voltage at which the cable can be safely operated. The test voltage of 2000 V serves quality assurance and ensures that the insulation remains intact even under increased electrical stress. The temperature range extends from -25 °C to +180 °C for movable use and from -40 °C to +180 °C for fixed installation. The cable can withstand temperatures up to +250 °C for short periods, making it suitable for temporary thermal peaks. The minimum bending radius is 6 times the cable diameter for fixed installation and 12 times for flexible use, taking into account mechanical stress during movement. The burning behavior corresponds to test method B according to IEC 332-1, meaning the cable is flame-retardant and self-extinguishing.

Compatibility and Accessories

The cable is designed for use in electrical installations subject to high thermal and mechanical loads. It can be combined with appropriate connectors, cable lugs and other connection elements suitable for silicone cables. The use of matching cable lugs and screw terminals is recommended to ensure a secure and durable connection.

Installation and Mounting

Installation must be carried out by qualified electricians in accordance with applicable regulations. The cable can be installed fixed or used movably, with the bending radius complying with the technical data. For movable use, a larger bending radius is required to extend the cable's service life. Connection techniques should be chosen to avoid transferring mechanical stress to the cable. The use of cable lugs or other suitable connection elements is recommended.

Operational Advantages

The cable offers high thermal resistance, enabling safe use in environments with high temperatures. The combination of silicone rubber and tinned copper strands ensures long service life and high reliability. The halogen-free composition reduces fire hazard and the toxicity of smoke gases. The good weather resistance makes the cable suitable for outdoor use as well. The flexibility for movable use and high mechanical durability expand its application range in industrial applications.
