High-temperature resistant silicone cable HELUTHERM SiHF 3G6 mm² brick red, conductor identification acc. to DIN VDE 0293-308 23041

High-temperature silicone cable – reliability in extreme conditions

This flexible, multi-strand silicone cable HELUTHERM SiHF is designed to operate in demanding environments where standard cables fail. It is characterized by exceptional resistance to extreme temperatures, both high and low, making it an ideal solution for a wide range of industrial applications. The cable is made of high-quality materials, ensuring long-lasting and safe operation.

Construction and properties

The HELUTHERM SiHF cable has a construction guaranteeing reliability and flexibility. It consists of multi-wire copper conductors, insulated with special silicone with high thermal resistance. The conductors are twisted in layers, and the whole is surrounded by a durable silicone coating in brick red color. This construction provides not only excellent electrical properties but also resistance to mechanical and chemical factors. Additionally, the cable is halogen-free, which increases safety and minimizes the emission of toxic substances in the event of a fire.

Applications and benefits

The HELUTHERM SiHF cable finds application in many industries, such as:

• Metallurgy and metalworking: Due to its resistance to high temperatures, it works perfectly in metallurgical environments.
• Glass and ceramics industry: Enables safe power supply to devices operating at high temperatures.
• Cement plants: Resistance to difficult working conditions and cement dust.
• Aerospace: Use in power and control systems requiring high reliability.
• Power plants: Safe connections in energy installations.
• Lighting: Powering luminaires exposed to high temperatures.

Thanks to its properties, this cable provides:

• Wide operating temperature range: from -60°C to +180°C (short-term up to +220°C).
• High flexibility: facilitates installation and routing of cables in tight spaces.
• Safety: the absence of halogen in the insulation minimizes the risk of toxic gas formation during a fire.
• Chemical resistance: the cable is resistant to oils, greases and many chemicals.
• Long-term operation: high-quality materials guarantee reliable operation for a long time.

The cable is available in various conductor cross-sections (e.g. 6 mm²) and number of conductors (3), allowing it to be adapted to specific installation needs. Remember that the minimum bending radius for flexible installations is 7.5 x cable diameter, and for fixed installations 4 x cable diameter – observing these rules will ensure proper cable operation for a long time.
