Single-core wire with fiberglass braiding, resistant to very high temperatures HELUTHERM® 400 1x1.5 beige, nickel-plated conductor 50954

Extreme durability in harsh conditions – HELUTHERM® 400 cable

This single-core cable with a fiberglass braid is a solution for demanding applications where standard cables fail. The HELUTHERM® 400 cable is distinguished by its exceptional resistance to very high temperatures, making it indispensable in specialized industries. The use of a nickel core ensures excellent conductivity and stability in difficult conditions.

Construction and application – from aerospace to metallurgy

This cable was designed for extreme environments. Its construction, based on a multi-strand nickel core surrounded by a special, heat-resistant fiberglass fabric, guarantees reliability even at temperatures up to +400°C (short-term up to +450°C). This makes it suitable for demanding industries:

• Aerospace and astronautics – where temperature and reliability are critical.
• Nuclear power plants – ensuring safety and continuity of operation in critical systems.
• Chemical industry – resistance to aggressive substances and high temperatures.
• Steelworks and foundries – durability in extreme thermal and mechanical conditions.
• Applications requiring radiation resistance.

Key features and benefits

The HELUTHERM® 400 cable is not only temperature resistant, but also offers a number of other advantages:

• Wide operating temperature range: from -60°C to +400°C (short-term up to +450°C) – ensures reliable operation in all conditions.
• Exceptional chemical resistance: ideal for environments with aggressive substances.
• Radiation resistance: allows use in applications exposed to ionizing radiation.
• Nickel core: guarantees high conductivity and electrical stability.
• Multi-strand core construction (class 2): provides flexibility and facilitates installation.
• Rated voltage 500V: allows use in various electrical installations.
• Minimum bending radius 15 x outer diameter: makes it easy to lay the cable even in tight spaces.

This cable complies with the CE standard (LVD 2014/35/EU), which confirms its safety and quality of workmanship. Additionally, an option with a Kapton foil is available for even greater protection. However, please note that at temperatures above 200°C, the impregnation varnish may degrade, leaving only the glass fibers as insulation - this is a natural process related to the high temperature resistance of the material.
