Silicone cable OLFLEX HEAT 180 SiHF 5G2,5 00460223

High-temperature silicone cable for extreme applications

The OLFLEX HEAT 180 SiHF cable is an advanced solution for installations requiring resistance to high temperatures and flexibility in harsh conditions. Designed to operate in a temperature range from -50°C to +180°C, it is ideal for use in industry, furnaces, heating systems, and anywhere standard cables fail. The construction with silicone insulation and jacket ensures reliability and long-term operation.

Flexibility and safety in one

Made of copper, the OLFLEX HEAT 180 SiHF cable has five cores with a cross-section of 2.5 mm², which guarantees sufficient current capacity for various applications. The cores are tinned for better contact and corrosion resistance. Additionally, the presence of a protective conductor increases safety. Its B characteristic allows it to react slower to short current surges, therefore it tolerates starting motors well. The cable is identified by core colors, which simplifies installation and servicing. Thanks to its flexibility, installation is easier even in tight spaces.

Applications and construction features

OLFLEX HEAT 180 SiHF is an excellent choice for:

• Industry: Machines and equipment operating at high temperatures.
• Heating systems: Heaters, furnaces, heating elements.
• Lighting: Lighting fixtures exposed to high temperatures.
• Industrial automation: Powering sensors and controllers in harsh conditions.
• Medical devices: Applications requiring high chemical and thermal resistance (after consultation).

The cable construction is designed for durability:

• Core insulation: Silicone rubber (SIR) – provides excellent dielectric properties and thermal resistance.
• Outer jacket: Silicone rubber (SIR) – protects against external factors and ensures flexibility.
• Core material: Copper – guarantees good electrical conductivity and mechanical strength.
• Cable geometry: Round – facilitates routing and installation.
• Oil resistance: The cable is resistant to oils according to IEC 60811-404, which increases its versatility in industrial applications.

After combustion, it has insulating properties due to the remaining SiO2 ash on the cores - an additional advantage increasing safety in the event of a failure. The minimum bending radius in moving installations is 174 mm, and in fixed installations 46.4 mm - it is worth considering this during installation design.
