Single-core PTFE cable HELUFLON®-PTFE-5Y 1xAWG16/19 (1.23 mm²) black, 600 V 25241

Highly durable PTFE cable for extreme conditions

This specialized HELUFLON-PTFE-5Y T.E 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 safety, making it an ideal choice for both professional installers and end users.

This cable finds wide application in installations and construction of switchgear cabinets operating in extreme temperatures – for example, in furnaces, brick factories, or kitchen appliances. It will also be useful in the chemical industry, where it is exposed to flames, acids, alkalis, solvents, oils, and gasoline.

Construction and properties

The cable construction is based on a silver-plated copper core, providing excellent conductivity and corrosion resistance. PTFE (polytetrafluoroethylene) insulation guarantees exceptional thermal resistance – the cable withstands temperatures from -190°C to +260°C (short-term up to +300°C). Additionally, PTFE provides excellent dielectric properties and chemical resistance.

It is worth noting the following features:

• High insulation resistance: minimizes the risk of breakdown and ensures safe operation.
• Low electrical losses: translate into efficient energy use.
• Non-flammability: increases installation safety in the event of a fire.
• Resistance to microorganisms and fungal growth: ensures hygiene and durability in demanding conditions.
• Complete resistance to ozone and weather conditions: allows the cable to be used outdoors.
• Minimal water absorption and permeability: protects against moisture damage.
• No silicone, cadmium, or substances that interfere with painting: guarantees compatibility with various materials.

The cable meets the requirements of DIN VDE 0881 and IEC 60673 standards, and also has a certificate of conformity with the Low Voltage Directive 2014/35/EU (CE). Tests confirm its self-extinguishing and flame-retardant properties in accordance with DIN VDE 0482-332-1-2, DIN EN 60332-1-2 and IEC 60332-1 standards.

Technical parameters

The HELUFLON-PTFE-5Y T.E cable with a cross-section of 1.23 mm² (AWG 16) has an approximate outer diameter of 2.24 mm. It is designed to operate at a voltage of 600V (type E) or 1000V (type EE), and the test voltage is 3.4kV or 5kV, respectively. Insulation resistance is at least 1GOhm x km, and the minimum bending radius is 10 x cable diameter. The cable is radiation resistant up to 1 x 10⁵ cJ/kg (up to 1 Mrad). The operating temperature range of the core depends on the core material: copper +130°C, tinned copper +180°C, silver-plated copper +200°C and nickel-plated copper +260°C.
