Helukabel SiHF Silicone Cable 2x0.75mm²

The Helukabel SiHF 2x0.75mm² silicone cable is a high-performance electrical conductor engineered for environments subject to extreme temperature fluctuations. Featuring a robust silicone insulation and a tinned copper core, this cable maintains its mechanical and electrical integrity in both freezing conditions and high-heat industrial settings. Its flexible design and halogen-free composition make it a reliable choice for demanding power supply and control applications where standard PVC cables would fail.

Advantages

The primary advantage of this cable lies in its exceptional thermal resilience, allowing it to function reliably at temperatures as low as -60°C and in high-heat environments. The silicone material is inherently resistant to ozone, oxygen, weathering, and various chemical agents, including alcohols, dilute acids, and animal or vegetable fats. Furthermore, the cable is halogen-free and flame-retardant, ensuring that it remains safe in the event of fire by leaving an insulating layer of SiO2, which prevents short circuits. Its finely stranded tinned copper construction provides excellent flexibility, facilitating easier installation in complex industrial machinery.

Suitable for

• Power stations and energy distribution systems
• Steel, glass, ceramic, and cement manufacturing plants
• Aviation and shipbuilding industries
• Industrial heating equipment and lighting systems
• Environments with high exposure to ozone or weathering

When it may not be suitable

This cable is not recommended for direct burial or installation in closed, non-ventilated conduits when operating at temperatures consistently above 90°C. In such conditions, the lack of air circulation can negatively impact the mechanical properties of the silicone insulation over time.

How to use

The Helukabel SiHF cable is designed for flexible connection and fixed installation. When installing, ensure the cable is routed through open, ventilated pipe or duct systems to maintain optimal performance, especially in high-temperature environments. The cores are colour-coded for easy identification during wiring. Ensure that the bending radius is respected during installation to maintain the integrity of the silicone insulation and the stranded copper conductors.

What to consider before purchase

• Verify the current and voltage requirements of your specific application.
• Ensure the installation environment allows for proper ventilation if operating above 90°C.
• Confirm the required length, as this cable is supplied in a drum format.
• Check that the chemical exposure in your facility is compatible with the resistance profile of silicone.

Usage recommendations: Always handle the cable with care to avoid mechanical damage to the silicone sheath. For fixed installations in high-temperature zones, prioritize ventilated cable trays to ensure the longevity of the insulation material.
