Single-core PTFE wire HELUFLON®-PTFE-5Y 1xAWG18/7 (0.90 mm²) red, 1000 V 25422

Durable PTFE cable for extreme conditions

This red HELUFLON-PTFE-5Y T.EE cable is a specialized solution for installations requiring the highest resistance to temperature, chemicals and harsh environmental conditions. Made with a silver-plated copper core and PTFE (polytetrafluoroethylene) insulation, this cable ensures reliable operation even in the most demanding applications. Ideal for both professional installers and end-users looking for a durable and safe solution.

Construction and properties

The cable is characterized by a unique construction that guarantees its long-term operation. The silver-plated copper core provides excellent conductivity, and the PTFE insulation – resistance to extreme temperatures (from -190°C to +260°C, briefly up to +300°C) and aggressive chemicals. Additionally, this material is flame retardant, resistant to microorganisms and fungal growth, making it an ideal choice for use in the chemical industry, bakeries, as well as in kitchen and measuring devices. The cable meets IEC 60332-1-2 standards regarding fire resistance.

• Wide operating temperature range allows operation from -190°C to +260°C (briefly up to +300°C) in extreme conditions.
• Exceptional chemical resistance protects against acids, alkalis, solvents, oils and gasoline – ideal for industrial environments.
• High insulation with a minimum resistance of 1 GOhm x km ensures safe use.
• Low water permeability (approx. 0.18 mg/cm2 over 24 hours) protects against corrosion.
• Radiation resistance up to 1 x 10⁵ cJ/kg (up to 1 Mrad) increases the cable's durability in exposed locations.
• Self-extinguishing material meeting DIN VDE 0482-332-1-2, DIN EN 60332-1-2 and IEC 60332-1 standards increases the fire safety of the installation.

Applications and specifications

The HELUFLON-PTFE-5Y T.EE cable with a cross-section of 1 x AWG 18/7 and a working voltage of 1000V is primarily used in control cabinet installations operating in difficult thermal conditions and in the chemical industry. Thanks to its properties, it is also perfect for use in furnaces, brick factories, as well as in kitchen and measuring devices. The minimum bending radius is 10 x cable diameter, which facilitates installation even in tight spaces. Available in red color (symbol "2" with the catalog number). To order a different color, add the appropriate symbol to the catalog number: 1 = black, 3 = blue, 4 = brown, 5 = white, 6 = transparent, 7 = two-color or 8 = other colors on request. The core can be supplied bare or tinned/nickel-plated on request.
