Built for the Heat – and the Cold
In demanding industrial environments, temperature extremes are more than a challenge—they're a constant. Whether in steel production, plastics processing, aviation, or manufacturing, cables must perform reliably under intense thermal conditions. That’s where HELUKABEL’s temperature-resistant cables come in.
Designed to thrive in both high-heat and sub-zero applications, our cables are engineered with precision materials like silicone, PTFE, and cross-linked insulation compounds. These robust constructions deliver long-term durability, electrical stability, and flexibility—without compromising safety or efficiency.
From flexible silicone cables for continuous movement at high temperatures, to rugged fixed-installation options that withstand freezing environments, HELUKABEL has the right solution to meet your operational demands.
Key Benefits of Our Temperature-Resistant Cables:
- Wide Operating Range: Suitable for use in temperatures from -60°C to +400°C, depending on the series.
- Exceptional Mechanical Strength: Maintains flexibility and integrity under dynamic conditions.
- Global Standards Compliance: UL, CSA, and VDE certified for peace of mind and easy integration.
- Versatile Applications: Perfect for use in heaters, ovens, cold storage, motor windings, and more.
Whether you’re retrofitting existing systems or designing new equipment, HELUKABEL’s temperature-resistant cables keep your systems running—no matter the climate.
