High temperature resistant silicone wire HELUTHERM SiHF 12G1 mm² brick red, core identification according to DIN VDE 0293-308 23135

High-temperature silicone cable – reliability in extreme conditions

This multi-core HELUTHERM SiHF cable, with insulation made of special silicone, is designed for operation in demanding industrial environments and applications where standard cabling fails. It is characterized by exceptional resistance to extreme temperatures, both high and low, making it an ideal choice where other cables degrade. This cable complies with DIN VDE 0250 part 1 and DIN VDE 0285-525-2-83 / DIN EN 50525-2-83.

Construction and properties

The cable is constructed of multi-strand copper conductors, twisted for flexibility and durability. Each conductor is insulated with special silicone, which guarantees resistance to temperatures up to +180°C (short-term up to +220°C) and low temperatures down to -60°C. Additionally, the silicone insulation provides excellent dielectric properties and chemical resistance to oils, greases and many other substances. The cable has 12 cores with a cross-section of 1 mm², allowing for use in various electrical installations. The outer jacket made of silicone in brick red color provides additional mechanical and chemical protection.

Applications and benefits

The HELUTHERM SiHF cable finds application in a wide range of industries, including:

• Metallurgical and foundry industry: Resistance to high temperatures makes it ideal for working near furnaces and other heat-generating equipment.
• Glass and ceramics industry: Resistance to extreme thermal conditions guarantees reliable operation in difficult production processes.
• Cement plants: Resistance to abrasion and mechanical damage ensures long-term operation in demanding working conditions.
• Aerospace industry: Lightweight construction and flexibility facilitate installation in limited space.
• Power plants: Non-halogenated material increases the fire safety of installations.
• Lighting installations: Provides safe and reliable connections in lighting systems exposed to high temperatures.

Thanks to its properties, this cable is particularly recommended for applications requiring high flexibility and resistance to external factors. It is an ideal solution for installers looking for reliable cabling for difficult applications and for end-users expecting long-lasting and safe operation. This cable is also characterized by the absence of halogen in its composition, which increases safety in the event of a fire – during combustion it releases SiO2 (silicon dioxide), not toxic gases.
