Single-core PTFE wire HELUFLON®-PTFE-5Y 1xAWG26/19 (0.14 mm²) brown, 1000 V 25354

Highly durable PTFE cable for extreme conditions.

This single-core HELUFLON-PTFE-5Y cable is a specialized solution designed for operation in demanding environments. It is characterized by exceptional resistance to temperature, chemicals and radiation, making it an ideal choice for industrial applications, switchgear cabinets and installations exposed to extreme conditions. This cable is particularly valued in furnaces, brickworks, kitchen and measuring devices, as well as in the chemical industry.

Construction and properties

The HELUFLON-PTFE-5Y cable consists of a silver-plated copper core, ensuring good conductivity and corrosion resistance. The insulation made of PTFE (polytetrafluoroethylene) guarantees unsurpassed resistance to high and low temperatures – from -190°C to +260°C (short-term up to +300°C). PTFE also provides excellent dielectric properties and chemical resistance. In addition, this material is non-flammable, resistant to microorganisms and fungi, and completely resistant to ozone and atmospheric conditions. Water absorption is minimal, which translates to long-term reliability.

Application and compliance with standards

This cable finds wide application in electrical installations requiring high reliability and safety. This is particularly important in industrial environments where extreme temperatures, aggressive chemicals or exposure to radiation occur. It meets the requirements of the Low Voltage Directive 2014/35/EU (CE marking), confirming its compliance with European safety standards. Thanks to its properties, this cable is also suitable for building switchgear cabinets operating in difficult conditions.

• Wide operating temperature range: from -190°C to +260°C (short-term +300°C) – enables use in extreme thermal conditions.
• Exceptional chemical resistance: ideal for environments with the presence of acids, bases, solvents, oils and gasoline.
• Non-flammability: increases the safety of installations in places with increased fire risk.
• Radiation resistance: allows use in applications exposed to ionizing radiation (up to 1 x 10⁵ cJ/kg).
• High insulation: minimum insulation resistance of 1 GΩ x km ensures effective protection against short circuits and leakage currents.
• Silver-plated core: provides better conductivity and corrosion resistance than traditional copper.
• Minimum bending radius: 10 x cable diameter facilitates assembly even in tight spaces.
