The Helukabel SiHF 2x1mm² is a high-performance silicone-insulated cable engineered for environments subject to extreme temperature fluctuations. Featuring two finely stranded tinned copper conductors, this cable maintains its electrical integrity and flexibility in both freezing conditions as low as -60°C and high-heat industrial settings. Its robust silicone construction ensures long-term durability and resistance to various environmental stressors, making it a reliable choice for demanding professional applications.
Advantages
This cable offers exceptional resistance to ozone, oxygen, weathering, and various chemical agents, including alcohols, dilute acids, and animal or vegetable fats. Its halogen-free composition and flame-retardant properties provide enhanced safety, as it leaves an insulating layer of SiO2 when exposed to flames, preventing short circuits. The finely stranded tinned copper conductors ensure excellent flexibility, allowing for easy installation in complex machinery or tight spaces without compromising electrical performance.
Suitable for
- Heating equipment and industrial ovens
- Sauna installations
- Lighting systems in high-temperature areas
- Steel, glass, and cement production facilities
- Shipbuilding and aviation industry applications
This cable is not suitable for applications requiring mechanical protection against heavy impact or abrasion, as the silicone sheath is designed for flexibility rather than high mechanical robustness. It should also not be used in closed, non-ventilated conduits when operating at temperatures consistently above 90°C, as the lack of air circulation can degrade the mechanical properties of the silicone insulation over time.
Key specifications
- Conductor cross-section: 2 x 1mm²
- Conductor material: Tinned copper, finely stranded
- Insulation and sheath material: Silicone
- Temperature range: Down to -60°C
- Flame-retardant: Yes, according to IEC 60332-1-2
- Halogen-free: Yes
- Chemical resistance: Ozone, oxygen, alcohols, dilute acids, and fats
To use the Helukabel SiHF cable, ensure that the installation environment allows for adequate ventilation, especially if the operating temperature exceeds 90°C. Strip the silicone sheath carefully to avoid damaging the inner cores. When connecting, ensure that the cable is properly secured to prevent excessive tension on the terminals. The cable is designed for both fixed and flexible connections, but it should be routed to avoid sharp edges that could compromise the integrity of the silicone jacket.
What to consider before purchase
- Verify the required current capacity for your specific application
- Ensure the installation environment provides sufficient airflow for high-temperature use
- Confirm the cable length needed for your project
- Check if the chemical resistance profile matches your specific industrial environment
Usage recommendations
For fixed installations at temperatures exceeding 90°C, always install the cable in open, ventilated pipe or duct systems to maintain the mechanical integrity of the silicone insulation.
