High-temperature resistant silicone cable HELUTHERM SiHF-OB 4x0.75 mm² brick red, core identification according to DIN VDE 0293-308 23105

Silicone cable for extreme conditions

This 4-core HELUTHERM SiHF-OB cable with a cross-section of 0.75 mm² is a reliable solution for applications requiring high thermal resistance and flexibility. The cable is designed to operate in a wide temperature range, from -60°C to +180°C (short-term up to +220°C), making it an ideal choice for installations in harsh industrial environments. Manufactured by HELUKABEL, it meets DIN VDE 0250 part 1 and DIN VDE 0285-525-2-83 / DIN EN 50525-2-83 standards, guaranteeing safety and reliability.

Construction and properties

The cable is characterized by a multi-core construction with special silicone insulation. The copper cores are twisted, which ensures flexibility and facilitates installation. Color identification of the cores according to DIN VDE 0293-308 makes correct connection easier. The outer jacket made of silicone provides additional protection against external factors. The cable is halogen-free, which increases safety in the event of a fire – during combustion, SiO₂ is released instead of toxic gases. The rated voltage is 300/500V, and the outer diameter is approximately 7.6 mm.

Applications and benefits

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

• Heavy industry: power plants, steelworks, foundries, cement plants.
• Shipbuilding industry: ship installations requiring resistance to moisture and corrosion.
• Food industry: applications where resistance to vegetable and animal oils and fats is required.
• Heating installations: underfloor or industrial heating systems where high temperatures occur.
• Industrial automation: connections in machines and devices operating in difficult environmental conditions.

Thanks to its construction, this cable offers:

• Exceptional thermal resistance: the ability to operate at extreme temperatures without loss of insulation properties.
• Flexibility: facilitates installation and routing of cables in tight spaces.
• Safety: the absence of halogen in the composition minimizes the risk of toxic gas formation in the event of a fire.
• Durability: high quality materials guarantee a long service life of the cable.
• Chemical resistance: resistant to many oils, fats, acids and alkalis.
