High-temperature resistant silicone cable HELUTHERM SiHF 2x0.5 mm² brick red, conductor identification acc. to DIN VDE 0293-308 22989

Silicone cable for extreme conditions

HELUTHERM SiHF 2x0.5 mm² cable is a flexible cable with silicone insulation, designed to operate in a wide temperature range – from -60°C to +180°C (short-term up to +220°C). Its construction and materials ensure reliable operation even in the most demanding industrial environments. This cable is particularly recommended for applications where standard wiring fails due to high temperature or extreme chemical conditions.

Construction and properties

The cable is characterized by a multi-strand, twisted copper conductor construction, which provides high flexibility. The silicone insulation guarantees resistance to high temperatures, chemicals, oils and radiation. The conductors are color-coded according to DIN VDE 0293-308 (brown and blue for 2x0.5 mm² cross-section), which facilitates identification during installation. The outer diameter of the cable is 5.6 mm. It should be noted that despite its high thermal resistance, this cable has limited mechanical strength – therefore, its proper protection against damage is important.

Applications and benefits

HELUTHERM SiHF cable finds application in many industries, including:

• Power industry: installations in power plants and substations.
• Metallurgy: wiring of furnaces and industrial equipment.
• Chemical industry: applications requiring resistance to aggressive substances.
• Food industry: devices operating at high temperatures (e.g. bakeries).
• Lighting: connections in lighting fixtures exposed to high temperatures.
• Aerospace: specialized applications requiring high reliability and thermal resistance.

Thanks to its properties, this cable provides:

• Safety: halogen-free insulation minimizes the risk of toxic gas formation in the event of a fire (compliant with IEC 60332-1-2 standard).
• Durability: resistance to extreme temperatures and chemicals extends the life of the cables.
• Flexibility: facilitates installation and routing of cables in tight spaces.
• Reliability: ensures a stable electrical connection even in difficult working conditions.
• Versatility: possibility of use in a wide range of voltages (300/500 V).
