The silicone cable SIAF 1.5 SW / SIF 1.5 SW from böhm Kabel is a flexible single conductor designed for use in industrial applications. It is used for internal wiring of luminaires, heating appliances, control panels, and distributors, particularly in sectors such as metallurgy, steel and rolling mill technology, industrial furnace and textile machinery construction, as well as lamp and electrical industry. The cable is characterised by its high heat resistance and halogen-free composition, making it suitable for demanding environments.

Applications
This cable is designed for flexible use in industrial plants where high temperatures, mechanical stress, or chemical influences may occur. It is commonly used in lighting technology, heating systems, and control panels where high thermal stability and durability are required. Its good weather resistance also makes it suitable for outdoor applications, provided that the mechanical and thermal loads in the intended application do not exceed the specified limits.

Functions and Features in Detail
The cable consists of a fine-stranded, tinned copper conductor, ensuring high flexibility and good electrical conductivity. The insulation is made of silicone rubber, a material known for its thermal and chemical resistance. The cable colour depends on the specific version, with black (RAL 9011) being a common variant. The cable is halogen-free, which reduces smoke development and toxic emissions in case of fire.

Technical Explanation
The rated voltage is 300/500 V, meaning the cable is designed for operating voltages up to 500 V in phase-to-conductor connections and up to 300 V in phase-to-neutral connections. The test voltage of 2000 V is used for quality control and ensures insulation strength. The temperature range extends from -25 °C to +180 °C for moving applications, from -60 °C to +180 °C for stationary applications, and up to +200 °C for short-term exposure. The minimum bending radius is 7.5 times the cable diameter, enabling flexible installation without damaging the insulation.

Compatibility and Accessories
The cable is designed for use in electrical installations requiring high thermal resistance. It can be combined with other silicone cables and wires, especially in systems exposed to high temperatures or mechanical stress. It can be used in conjunction with suitable connectors, terminals, or switching devices, provided these are also designed for the relevant operating conditions.

Installation and Mounting
Installation is carried out by securing the cable to appropriate supports or within cable ducts. Due to its flexible structure and small bending radius, installation is straightforward. The cable should be routed in such a way that the bending radius is not undershot to protect the insulation. During installation, ensure that the ambient temperature remains within the permissible range.

Operational Advantages
The cable offers high thermal stability, ensuring long service life and reliability in demanding environments. Its halogen-free composition reduces the formation of toxic smoke gases in case of fire. Good weather resistance allows outdoor use, provided no additional mechanical or chemical stresses are present. The flexibility of the fine-stranded copper conductor facilitates routing and installation in confined spaces.
