High temperature resistant silicone cable HELUTHERM SiHF 4x0.5 mm² brick red, core identification acc. to DIN VDE 0293-308 22941

High-temperature silicone cable – reliability in extreme conditions

This 4-core HELUTHERM SiHF cable with a cross-section of 0.5 mm² is the ideal solution for applications requiring high temperature resistance and flexibility. The cable is characterized by exceptional durability and reliability, making it an excellent choice for both professional installers and end users. The use of silicone insulation and sheathing ensures safety and long-term operation even in the most demanding environments.

Construction and properties

The cable is designed for extreme working conditions. Its construction is based on stranded copper conductors, twisted according to DIN VDE 0295 cl. 5, which ensures high flexibility and resistance to bending. Silicone rubber insulation guarantees resistance to temperatures from -60°C to +180°C (short-term up to +220°C), as well as to oils, greases, chemicals and radiation. The cores are colored according to DIN VDE 0293-308, which facilitates identification during installation. Additionally, the cable is halogen-free, which increases safety in the event of a fire – during combustion, SiO₂ is released instead of toxic gases.

Applications and benefits

The HELUTHERM SiHF cable finds application in a wide range of industries where elevated temperatures or chemical resistance are present. It is ideal for:

• Heavy industry: power plants, steelworks, foundries, cement plants, shipbuilding industry.

• Heating devices: industrial furnaces, heating systems.

• Laboratory equipment: measuring devices, research equipment.

• Automotive: electrical connections in engines and other components exposed to high temperatures.

• Industrial installations: where high flexibility and resistance to external factors are required.

Thanks to its construction, this cable offers a number of benefits:

• Wide operating temperature range: from -60°C to +180°C (short-term up to +220°C).

• Chemical resistance: to oils, greases, acids, alkalis and other chemicals.

• Halogen-free: increased fire safety.

• Flexibility: facilitates installation even in tight spaces.

• Durability: ensures long-lasting and reliable operation.

• Compliance with standards: DIN VDE 0250 part 1 and DIN VDE 0285-525-2-83 / DIN EN 50525-2-83

The cable has an outer diameter of approximately 6.4 mm and a rated voltage of U/Uo 300/500 V. The insulation resistance is at least 200 MOhm x km at a test voltage of 2000 V and a breakdown voltage of at least 5000 V. The minimum bending radius is 7.5 x cable diameter for flexible bending and 4 x cable diameter for stationary bending.
