High temperature resistant silicone cable HELUTHERM SiHF 5G10 mm² brick red, core identification acc. to DIN VDE 0293-308 23049

High-temperature silicone cable – reliability in extreme conditions

This multi-core HELUTHERM SiHF cable, with insulation made of special silicone, is designed to operate in demanding industrial environments and beyond. It is characterized by exceptional resistance to high and low temperatures, making it an ideal solution where standard cables fail. This cable complies with DIN VDE 0250 part 1 and DIN VDE 0285-525-2-83 / DIN EN 50525-2-83 standards, guaranteeing safety and reliability.

Construction and properties

The cable is made of multi-wire, stranded tinned copper conductors (class 5 according to PN-EN 60228). Each conductor is surrounded by flexible silicone insulation, available in various colors according to DIN VDE 0293-308 – up to 5 cores the colors are standard, above 5 cores – black with white numbering. The protective conductor (green-yellow) is available from 3 cores cross-section. The strands are twisted in parallel and surrounded by an outer silicone jacket in brick red color. This construction provides not only high flexibility but also resistance to chemical factors such as oils, vegetable and animal fats, alcohols, and many acids and alkalis.

This cable stands out with a wide range of operating temperatures – from -60°C to +180°C (short-term up to +220°C). Additionally, it is halogen-free (according to VDE 0482 part 267 / DIN EN 50267-2-2 / IEC 60754-2), which increases safety in case of fire – during combustion it leaves only SiO₂ insulation. The rated voltage is 300/500V, and the test voltage is 2000V.

Applications

The HELUTHERM SiHF cable finds application in many branches of industry:

• Power industry: Power plants, substations
• Metallurgy: Furnaces, induction furnaces
• Metal industry: Glass and ceramics factories
• Shipbuilding industry: Ship installations
• Cement plants: Production lines
• Lighting: Lighting devices and installations
• Other: all kinds of applications requiring high thermal and chemical resistance.

Thanks to its flexibility and resistance to extreme conditions, this cable is ideal for both fixed and mobile installations. The minimum bending radius for mobile installations is 7.5 x cable diameter, and for fixed installations – 4 x cable diameter. This cable is also radiation resistant up to 20 x 10⁶ cJ/kg (up to 20 Mrad).

This cable is a solid choice for professionals looking for a reliable solution in difficult conditions and for end customers expecting long-lasting and safe operation.
