High temperature resistant silicone wire HELUTHERM SiHF 25G0,75 mm² brick red, core identification according to DIN VDE 0293-308 23132

High-temperature silicone cable – reliability in extreme conditions

This multi-core cable with silicone insulation is designed to operate in demanding environments where standard cabling fails. It is characterized by exceptional resistance to high and low temperatures, making it an ideal choice for industrial and specialized applications. The cable meets the standards DIN VDE 0250 part 1 and DIN VDE 0285-525-2-83 / DIN EN 50525-2-83, guaranteeing safety and reliability.

Construction and properties

The HELUTHERM SiHF cable consists of flexible, multi-strand tinned copper conductors, class 5 (according to PN-EN 60228). Each core is insulated with special silicone rubber, providing excellent dielectric and thermal properties. The cores are twisted in layers in the center, and the whole is surrounded by a silicone rubber coating in brick red color. This construction provides not only protection against external factors but also flexibility and ease of installation. Core identification is done using colors (according to DIN VDE 0293-308).

Applications and benefits

This cable is widely used in the metallurgical industry, glass and ceramics factories, cement plants, aviation, and in lighting devices and installations. Its resistance to extreme temperatures (from -60°C to +180°C, briefly up to +220°C) as well as chemical resistance and oil resistance make it an ideal solution where other cables fail. Additionally, the cable is halogen-free, which increases safety.

• Wide operating temperature range: Enables use in extreme thermal conditions – both high and low.
• Exceptional flexibility: Thanks to the multi-strand core construction, the cable is easy to install and route.
• Chemical resistance: Ensures long-term operation in aggressive environments.
• Halogen-free: Increases fire safety and minimizes the emission of toxic substances during combustion.
• Compliance with standards: Meets the requirements of DIN VDE 0250 part 1 and DIN VDE 0285-525-2-83 / DIN EN 50525-2-83, guaranteeing quality and safety.
• Rated voltage: Designed to operate at voltages up to 500 V (U) / 300 V (U0).

The HELUTHERM SiHF cable is an investment in reliable cabling that can handle even the most demanding tasks. Its durability and resistance to extreme conditions ensure long-lasting and safe operation.
