Single-core PTFE wire HELUFLON®-PTFE-5Y 1xAWG22/7 (0.35 mm²) blue, 600 V 25183

PTFE wire for extreme conditions

This specialized HELUFLON-PTFE-5Y T.E wire, with a cross-section of 0.35 mm² and an outer diameter of approximately 1.47 mm, is designed for operation in demanding environments. It is characterized by high temperature resistance – from -190°C to +260°C (short-term up to +300°C) – making it an ideal choice for industrial applications such as furnaces, brickworks, kitchen appliances or measuring devices. This wire is also resistant to chemicals, oils, gasoline and radiation.

Construction and properties

The wire is made of silver-plated copper core, ensuring good conductivity and durability. PTFE (polytetrafluoroethylene) insulation guarantees exceptional resistance to external factors and ensures safe use. PTFE is a material with low water permeability and high chemical resistance – these are key features in applications exposed to an aggressive environment. Additionally, the wire is non-flammable and resistant to the development of microorganisms and fungi.

• Silver-plated copper core ensures reliable connection.
• PTFE insulation guarantees high thermal and chemical resistance.
• Low electrical losses minimize voltage drop on the cable.
• Radiation resistance allows use in environments exposed to ionizing radiation.
• Meets the requirements of IEC 60332-1-2 standard in terms of fire resistance.

Application and compliance with standards

The HELUFLON-PTFE-5Y T.E wire is used in installations and construction of switchboard cabinets operating in extreme conditions, as well as in the chemical industry, where resistance to aggressive chemicals is required. This is a product compliant with the Low Voltage Directive 2014/35/EU (CE marking). The rated voltage U0/U is 600 V, making it suitable for many industrial and commercial applications. The minimum bending radius is 10x the cable diameter, which facilitates installation even in tight spaces.
