High-temperature resistant silicone cable HELUTHERM SiHF 7G1.5 mm² brick red, conductor identification acc. to DIN VDE 0293-308 23018

High-temperature silicone cable – reliability in extreme conditions

This multi-core HELUTHERM SiHF cable, with insulation made of special silicone, is designed to operate in demanding industrial environments and applications where standard cabling fails. It is characterized by exceptional resistance to high and low temperatures, making it an ideal choice for applications requiring reliability and safety. This cable is particularly valued in industries such as metallurgy, cement plants, power plants, and the shipbuilding industry.

Construction and properties

The HELUTHERM SiHF 7G1,5 mm² cable has a construction that ensures flexibility and durability. It consists of seven stranded and twisted copper cores, providing good flexibility. Each core is insulated with special silicone, resistant to extreme temperatures – from -60°C to +180°C (short-term up to +220°C). The cores are twisted in layers around a center, and the whole is surrounded by an outer silicone coating in brick red color. Additionally, the cable is halogen-free, which increases safety and minimizes the emission of toxic substances in the event of a fire.

Applications and benefits

This cable finds wide application where standard cables do not meet temperature or chemical requirements. It is ideal for:

• Heavy industry: steel, glass and ceramics plants, cement plants – everywhere where high temperatures and an aggressive environment occur.
• Power plants: energy installations requiring high reliability and resistance to environmental conditions.
• Shipbuilding industry: marine applications exposed to moisture, salt and extreme temperatures.
• Heating devices: connecting heating elements operating at high temperatures.
• Industrial lighting: powering lighting fixtures exposed to high temperatures.

By choosing the HELUTHERM SiHF cable you gain:

• Exceptional thermal resistance: continuous operation in the range of -60°C to +180°C and short-term resistance up to +220°C guarantees reliable operation even in the most extreme conditions.
• Safety: halogen-free construction minimizes the risk of toxic gas emissions during a fire.
• Flexibility: stranded core construction provides easy installation and adaptation to various installation configurations.
• Chemical resistance: the cable is resistant to oils, vegetable and animal fats, alcohols and many other chemicals.
• Compliance with standards: the cable meets the requirements of DIN VDE 0250 part 1 and DIN VDE 0285-525-2-83 / DIN EN 50525-2-83, confirming its high quality and safety.

The 1.5 mm² core cross-section makes this cable versatile and can be used in many different electrical applications requiring flexibility and high temperature resistance. Core identification according to DIN VDE 0293-308 facilitates correct connection of the wires during installation.
