The silicone hose cable SIHF-JB 4G2,5 from böhm Kabel is a heat-resistant cable for movable connection applications in environments with high temperatures. It is used in industrial sectors such as metallurgy, steel and rolling mill technology, packaging machinery construction, 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 features a reddish-brown silicone rubber sheath and is designed for use in harsh environments.

Applications

The cable is specifically designed for movable connections where high thermal loads occur. It is suitable for applications in industrial manufacturing, where machines and devices are operated under high temperatures. The fields of application also include heating and cooling technology as well as safety technology, where high reliability and thermal stability are required. The cable is suitable for outdoor use, as it exhibits good weather resistance.

Functions and Equipment in Detail

The cable consists of tinned copper strands of class 5, which ensure high flexibility. The conductors are insulated with silicone rubber, ensuring high heat resistance and chemical resistance. Conductor identification follows VDE 0293-308, with black conductors being numbered from six conductors onwards and the protective conductor being green-yellow. The sheath is also made of silicone rubber and is reddish-brown, enabling good visibility and identification.

Technology Explained Simply

The cable is halogen-free, meaning that no toxic halogen hydrogen compounds are released in the event of a fire. It is heat-resistant and can withstand temperatures from -25 °C to +180 °C for movable use and from -40 °C to +180 °C for non-movable use. Short-term temperatures up to +250 °C are possible. The bending strength is designed for free installation with a minimum bending radius of 6 times the cable diameter and for flexible use with 12 times the cable diameter. The burning behaviour corresponds to test method B according to IEC 332-1, indicating flame-retardant and self-extinguishing properties.

Compatibility and Accessories

The cable is designed for use in industrial plants and machines where high thermal and mechanical loads occur. It is compatible with standard cable glands and connectors designed for silicone cables. Use in combination with other heat-resistant components is possible, provided the respective standards and requirements are met.

Installation and Mounting

Installation is typically carried out by qualified personnel. The cable can be installed exposed, with the minimum bending radius being observed. For flexible use, a larger bending radius is required. Connections to devices are made using suitable connectors or cable glands designed for silicone cables.

Operational Advantages

The cable offers high thermal resistance, enabling a long service life even under high temperatures. Cold flexibility ensures safe operation even at low temperatures. The halogen-free composition increases safety in the event of fire. Good weather resistance makes the cable suitable for outdoor use. Self-extinguishing and flame-retardant properties reduce fire risk.

Protection Rating

Weather resistance is achieved through material selection (silicone rubber), although no specific IP rating is assigned.

Operating Voltage

The rated voltage is 300/500 V, typical for use in industrial plants and machines. The test voltage of 2000 V ensures electrical insulation under high voltage loads.

Temperature Range

The cable can withstand temperatures from -25 °C to +180 °C for movable use and from -40 °C to +180 °C for non-movable use. Short-term temperatures up to +250 °C are possible, making it suitable for short-term thermal peak loads.

Bending Radius

The minimum bending radius is 6 times the cable diameter for free installation and 12 times the cable diameter for flexible use, ensuring safe and durable bending.

Burning Behaviour

The burning behaviour corresponds to test method B according to IEC 332-1, indicating flame-retardant and self-extinguishing properties. This reduces fire risk during operation.

Material

The cable consists of tinned copper strands of class 5, silicone rubber as conductor insulation and sheath material. The silicone rubber is halogen-free, heat-resistant and cold-flexible.

Colour
