Single-core PTFE wire HELUFLON®-PTFE-5Y 1xAWG26/19 (0.14 mm²) white, 1000 V 25355

Durable PTFE cable for extreme conditions

The HELUFLON-PTFE-5Y cable is a specialized solution for installations requiring high resistance to temperature, chemicals, and harsh environmental conditions. It is ideal for building switchgear cabinets, furnaces, brick factories, kitchen appliances, measuring devices, and in the chemical industry. Its construction and materials guarantee reliability and safety in demanding applications.

Construction and properties

The cable is characterized by a silver-plated copper core, which ensures excellent conductivity and corrosion resistance. The PTFE (polytetrafluoroethylene) insulation – a material with exceptional properties – guarantees resistance to high temperatures (up to +260°C, briefly even +300°C) and aggressive chemicals such as acids, alkalis, solvents, oils, and gasoline. Additionally, PTFE is non-flammable and resistant to microorganisms and fungal growth. Complete resistance to ozone and atmospheric conditions ensures that the cable retains its properties for a long time.

• Wide operating temperature range: from -190°C to +260°C (briefly up to +300°C), allowing use in extreme conditions.
• High chemical resistance: ideal for environments exposed to aggressive substances.
• Low electrical losses: ensures efficient energy transmission.
• Non-flammability: increases installation safety.
• Radiation resistance: enables use in specific industrial applications (up to 1 x 10⁵ cJ/kg).
• Minimal water absorption: ensures stable electrical parameters even in humid environments.
• Compliance with standards: the product meets the requirements of the Low Voltage Directive 2014/35/EU (CE marking).

User parameters and installation

The HELUFLON-PTFE-5Y cable with a cross-section of 1xAWG26/19 (white) has a working voltage of 1000V (EE type) and a test voltage of 5kV. The minimum bending radius is 10 x cable diameter, which facilitates installation even in tight spaces. The core is available in a bare version or tinned/nickel-plated on request – it is worth considering this when choosing a cable for a specific application. To order the cable in a color other than white, add the appropriate symbol to the catalog number: 1 = black, 2 = red, 3 = blue, 4 = brown, 5 = white, 6 = transparent, 7 = two-color or 8 = other color.
