Single-core PTFE wire HELUFLON®-PTFE-5Y 1xAWG20/7 (0.57 mm²) brown, 1000 V 25404

Durable PTFE cable for extreme conditions

This brown HELUFLON-PTFE-5Y T.EE cable, with a cross-section of 1xAWG20/7, is a specialized solution for installations requiring the highest resistance to external factors. Made with a silver-plated copper core and PTFE (polytetrafluoroethylene) insulation, it ensures reliable operation even in the most demanding industrial and temperature conditions. The cable is designed for operation at 1000V and is characterized by high resistance to radiation, chemicals, and fire.

Construction and properties for professionals

The cable construction is based on silver-plated copper cores, which increases its conductivity and corrosion resistance. PTFE insulation – a material with exceptional dielectric properties – guarantees high temperature resistance (from -190°C to +260°C, briefly up to +300°C) and excellent electrical parameters. This makes the cable perfect for installations exposed to extreme temperatures, such as furnaces, brickworks, or kitchen appliances. Additionally, PTFE provides resistance to aggressive chemicals – acids, bases, solvents, oils, and gasoline – making it an ideal choice for the chemical industry. The cable meets the requirements of DIN VDE 0881 and IEC 60673 standards.

Applications and benefits

The HELUFLON-PTFE-5Y cable is widely used in:

• Distribution board installations: especially in places exposed to high temperatures.
• Chemical industry: as a cable resistant to aggressive environments.
• Heating devices: furnaces, dryers, kitchen appliances.
• Measurements: where precision and stability of electrical parameters are required.
• Applications requiring high fire resistance: thanks to the IEC 60332-1-2 certificate confirming its self-extinguishing and flame-retardant properties.

Additional advantages:

• High insulation resistance: minimizes the risk of breakdown and ensures safe use.
• Low electrical losses: translate into energy efficiency of the installation.
• Resistance to microorganisms and fungi: ensures hygiene and durability in difficult conditions.
• Complete resistance to ozone and weather conditions: guarantees reliability in outdoor applications.
• Minimal water absorption: protects against corrosion and loss of insulating properties.

To order the cable in a color other than brown, please add the appropriate symbol to the catalog number: 1 = black, 2 = red, 3 = blue, 5 = white, 6 = transparent, 7 = two-color or 8 = other colors. The core can be supplied bare or tinned/nickel-plated on request.
