High-temperature resistant silicone cable HELUTHERM SiHF 3G2.5 mm² brick red, conductor identification acc. to DIN VDE 0293-308 23028

High-temperature silicone cable – reliability in extreme conditions

This flexible silicone cable HELUTHERM SiHF 3G2,5 mm² is an ideal solution for applications requiring resistance to very high and low temperatures. The cable is designed to operate in harsh industrial conditions, ensuring the reliability and safety of installations. Its construction based on special silicone guarantees long-term operation even in the most demanding environments.

Construction and properties

The cable is characterized by a multi-core construction with insulation made of special silicone, which ensures high thermal resistance in accordance with DIN VDE 0250 part 1 and DIN VDE 0285-525-2-83 / DIN EN 50525-2-83 standards. It withstands operating temperatures from -60°C to +180°C, and briefly up to +220°C. Additionally, the cable is resistant to low temperatures down to -60°C. The copper cores are stranded, flexible (class 5), which facilitates assembly and ensures connection flexibility. The core color scheme complies with DIN VDE 0293-308, and the protective conductor is yellow-green (from 3 cores).

This cable is halogen-free, which increases safety in the event of a fire – during combustion, SiO₂ insulation is released, which does not spread flames. It is also resistant to oils, vegetable and animal fats, alcohols, acids, alkalis, and atmospheric conditions and UV radiation.

Applications

The HELUTHERM SiHF 3G2,5 mm² cable finds application in a wide range of industrial sectors:

• Power plants
• Steelworks and foundries
• Shipbuilding industry
• Cement plants
• Heating installations
• Industrial furnaces
• High-temperature lighting
• Laboratory equipment
• Wherever high thermal and chemical resistance is required

Thanks to its properties, it works perfectly where standard cables fail. This is particularly important in applications exposed to extreme temperatures or an aggressive chemical environment. Its flexibility makes it easy to route in tight spaces and provides convenience during installation.
