High temperature resistant silicone cable HELUTHERM SiHF 8G2.5 mm² brick red, conductor identification acc. to DIN VDE 0293-308 23140

High-temperature silicone cable – reliability in extreme conditions

This 8-core HELUTHERM SiHF cable, with a cross-section of 2.5 mm², is a specialized solution for applications requiring resistance to very high and low temperatures. The use of silicone insulation and sheathing ensures reliable operation in harsh industrial conditions where standard cables fail. The cable complies with DIN VDE 0250 part 1 and DIN VDE 0285-525-2-83 / DIN EN 50525-2-83 standards, guaranteeing its safety and quality.

Construction and properties

The cable is characterized by a flexible construction with a multi-strand copper core (class 5 according to DIN VDE 0295). The cores are insulated with special silicone, resistant to extreme temperatures – from -60°C to +180°C, and briefly up to +220°C. The core color scheme complies with DIN VDE 0293-308 (up to 5 cores – colored, above 6 – black with white numbering), and the protective core (available in a version with a protective core) is yellow-green. The outer jacket made of silicone provides additional protection and resistance to external factors. The cable is halogen-free, which increases safety in the event of a fire – during combustion, SiO₂ insulation remains.

Applications and benefits

The HELUTHERM SiHF cable finds application in a wide range of industries where extreme thermal conditions prevail:

• Power plants: Due to the high ignition temperature and resistance to atmospheric conditions.
• Steelworks and foundries: Resistance to high temperatures and an aggressive environment.
• Shipbuilding industry: Resistance to moisture, salt water and variable temperatures.
• Cement plants: Resistance to dust and high temperatures.
• Chemical industry: Resistance to oils, greases, acids and other chemicals.
• Heating installations: Safe routing of cables near heat sources.

Additional advantages:

• High flexibility: Facilitates installation and routing of cables in tight spaces.
• Chemical resistance: Ensures long-term operation in an aggressive environment.
• Halogen-free: Increases fire safety.
• Wide temperature range: Guarantees reliability in extreme conditions.
• Good dielectric properties: Ensure stable operation of the electrical installation even at elevated temperatures.

The cable is available in brick red (ruddy) color and is supplied in meter lengths. The outer diameter of the cable is approximately 13.6 mm with a permissible rated voltage U equal to 500V.
