Helukabel SiF Silicone Cable 1x1.5mm² Black 300/500V

The Helukabel SiF 1x1.5mm² silicone cable is a high-performance single-core conductor engineered for demanding industrial environments where thermal stability is critical. Featuring a finely stranded tinned copper conductor and robust silicone insulation, this cable provides exceptional flexibility and long-term reliability. It is specifically designed to maintain its electrical and mechanical properties in settings subject to extreme temperature fluctuations and exposure to various chemical agents.

Advantages

This cable stands out due to its superior resistance to environmental stressors, including ozone, oxygen, and various chemical substances such as alcohols, dilute acids, and saline solutions. Its halogen-free construction ensures safety in the event of fire, as it produces minimal corrosive gases and is flame-retardant. The use of tinned copper strands enhances corrosion resistance, while the high-quality silicone insulation allows for consistent performance in high-heat applications where standard PVC cables would fail.

Suitable for

• Iron, steel, and rolling mills
• Foundries and metal processing plants
• Cement, glass, and ceramic manufacturing facilities
• Aircraft construction and maintenance
• Shipbuilding and marine electrical systems

This cable is not suitable for applications requiring mechanical protection against heavy impact or abrasion, as the silicone insulation is softer than standard thermoplastic materials. It should not be used in direct burial installations or submerged in liquids for extended periods without appropriate protective conduit.

Key specifications

• Cross-section: 1.5 mm²
• Voltage rating: 300/500V
• Conductor material: Tinned copper, finely stranded
• Insulation material: Silicone
• Temperature resistance: High-temperature rated
• Fire safety: Halogen-free and flame-retardant
• Chemical resistance: Resistant to oils, fats, alcohols, and saline solutions

How to use

The Helukabel SiF cable is intended for fixed installations. When installing, ensure the cable is placed in open, ventilated pipe or duct systems. This ventilation is essential when operating in environments exceeding 90°C, as the absence of air circulation can negatively impact the mechanical integrity of the silicone insulation over time. Ensure that the bending radius is respected during installation to prevent damage to the fine strands.

What to consider before purchase

• Verify the current-carrying capacity requirements for your specific application.
• Ensure the installation environment allows for adequate airflow if temperatures are expected to exceed 90°C.
• Confirm that the cable will not be subjected to sharp edges or high mechanical abrasion.

Usage recommendations

For optimal longevity, avoid installing this cable in airtight enclosures where heat can accumulate. Always use appropriate cable glands and support systems to prevent mechanical strain on the connection points.
