High temperature resistant silicone cable HELUTHERM SiHF 3G16 mm² brick red, core identification according to DIN VDE 0293-308 23051

High-temperature silicone cable – reliability in extreme conditions

This multi-core HELUTHERM SiHF cable is a solution for demanding applications where standard cables fail. Designed to operate in a wide temperature range, from -60°C to +180°C (short-term up to +220°C), it is perfect for use in industry, energy, and anywhere where temperature is a challenge. This cable is distinguished not only by its resistance to high temperatures but also by its flexibility and durability.

Construction and properties

The cable is made of multi-strand copper conductors class 5, which provides it with high flexibility and resistance to mechanical fatigue. Silicone insulation guarantees excellent dielectric properties even at elevated temperatures and resistance to many chemical substances – oils, greases, acids, alkalis, and others. The outer jacket made of silicone provides additional protection of the cable against external factors. Brick-red color facilitates identification of the cores according to DIN VDE 0293-308 standard.

This cable is halogen-free, which increases safety and minimizes the emission of toxic substances in the event of a fire. It also features high resistance to UV radiation.

Applications and benefits

This cable finds application in many branches of industry:

• Energy: installations in power plants, energy distribution stations.
• Metallurgical industry: metallurgical furnaces, foundries.
• Chemical industry: installations exposed to aggressive chemical substances.
• Shipbuilding industry: wiring of machines and equipment operating in difficult atmospheric conditions.
• Cement plants: installations exposed to high temperatures and dust.
• Specialized applications: anywhere where high thermal and chemical resistance of cables is required.

Thanks to its construction and properties, the HELUTHERM SiHF cable provides:

• Safety: the absence of halogen in the insulation minimizes the risk of toxic gas formation during a fire.
• Durability: resistance to high temperatures, chemicals, and UV radiation ensures long-term operation.
• Flexibility: flexible conductors facilitate installation and laying of cables even in tight spaces.
• Reliability: high quality materials and precise workmanship guarantee stable operating parameters for a long time.

The cable has a rated voltage of U 500V and a conductor cross-section of 16 mm². Its approximate outer diameter is 19.3 mm. The insulation resistance is minimum 20 MOhm x km and the test voltage is 2000 V AC.
