High temperature resistant silicone wire HELUTHERM SiHF 8G1 mm² brick red, core identification according to DIN VDE 0293-308 23133

High-temperature silicone cable – reliability in extreme conditions

This multi-core HELUTHERM SiHF cable, with insulation made of durable silicone, 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 solution for a wide range of industrial applications. This cable is particularly valued for its flexibility and safety – it is halogen-free, minimizing the risk of toxic gas formation in the event of a fire.

Construction and properties

The cable is constructed of multi-strand copper conductors, twisted to ensure maximum flexibility. Each conductor is insulated with a special silicone mixture, guaranteeing resistance to temperatures up to +180°C (short-term up to +220°C) and low temperatures down to -60°C. The conductors are twisted in layers around a core, and the whole is surrounded by a durable, brown silicone coating. The conductor color scheme complies with DIN VDE 0293-308, which facilitates identification and improves installation safety. Radiation resistance up to 20 x 10⁶ cJ/kg (up to 20 Mrad) further expands the range of applications.

This cable also boasts good dielectric properties at elevated temperatures and resistance to oils, greases, alcohols and many other chemicals. This is crucial in industrial environments exposed to contact with aggressive media.

The HELUTHERM SiHF cable finds application in many industries, such as:

• Power plants
• Steelworks and foundries
• Shipbuilding industry
• Cement plants
• Heating installations
• Industrial lighting
• Industrial automation
