Single-core PTFE wire HELUFLON®-PTFE-5Y 1xAWG20/7 (0.57 mm²) black, 1000 V 25401

Durable PTFE cable for extreme conditions

This specialized HELUFLON-PTFE-5Y cable is a reliable solution for installations requiring resistance to high temperatures, aggressive chemicals, and harsh environmental conditions. The cable is characterized by exceptional durability and flexibility, making it an ideal choice for both professional installers and end-users looking for a safe and long-lasting solution.

The cable is made of silver-plated copper core, ensuring excellent conductivity and corrosion resistance. PTFE (polytetrafluoroethylene) insulation guarantees resistance to temperatures ranging from -190°C to +260°C (short-term up to +300°C), as well as resistance to chemicals, oils, gasoline, and radiation. This makes it suitable for use in furnaces, brickworks, kitchen appliances, measuring devices, and the chemical industry.

Construction and properties

The cable's construction is based on a combination of high-quality materials and precise production technology. The silver-plated copper core provides excellent electrical conductivity, and the PTFE-HELUFLON® insulation guarantees reliable protection against external factors. Additionally, the cable is characterized by:

• High insulation resistance – minimum insulation resistance is 1 GOhm x km.
• Low electrical losses – which translates to energy efficiency of the installation.
• Non-flammability – self-extinguishing and flame-retardant material, tested according to DIN VDE 0482-332-1-2, DIN EN 60332-1-2 and IEC 60332-1 standards.
• Resistance to microorganisms and fungal growth – ensuring hygiene and safety of use.
• Complete resistance to ozone and weather conditions – guaranteeing long-term reliability in all conditions.
• Minimal water absorption and permeability – protecting against moisture damage.

The cable meets the requirements of the Low Voltage Directive 2014/35/EU (CE marking), which confirms its safety and compliance with European standards. Available in black color (symbol 1 in the catalog number). Other colors available on request (red - 2, blue - 3, brown - 4, white - 5, transparent - 6, two-color - 7 and other colors - 8). The core can be supplied bare or tinned/nickel-plated on request.
