Single-core FEP wire, resistant to high temperatures HELUFLON®-FEP-6Y 1x2.5 mm² brown, conductor: silver-plated copper 20324

Single-core FEP wire – reliability in extreme conditions

This brown HELUFLON®-FEP-6Y single-core wire with a cross-section of 2.5 mm² is a specialized solution for applications requiring high thermal and chemical resistance. Made of silver-plated copper, it provides excellent conductivity and long-lasting reliability even in the most demanding environments. This wire is used both in industrial installations and in the construction of switchboard cabinets, where standard cabling fails.

Construction and properties

The wire is characterized by an advanced construction using FEP (HELUFLON®) fluoropolymer insulation. This innovative insulation guarantees exceptional resistance to high temperatures – from -100°C to +205°C (short-term up to +230°C) – and to aggressive chemicals such as alkalis, acids, oils and gasoline. The core made of silver-plated copper provides not only excellent electrical conductivity but also increases resistance to corrosion. The wire has a core class of 5, which means it is a flexible stranded core – easy to install and adapting to the shape of the installation. Its outer diameter is approximately 2.8 mm.

Applications and benefits

The HELUFLON®-FEP-6Y wire is ideal for use in:

• Chemical industry: thanks to its resistance to aggressive chemicals.
• Furnaces, brickworks and heating devices: due to its high thermal resistance.
• Kitchen and measuring devices: where reliability and safety are required.
• Switchboard cabinets: in places exposed to extreme temperatures.
• Industrial installations: where standard cables fail.

Additional advantages:

• High insulation resistance: minimizes the risk of breakdown and ensures safe operation.
• Low dielectric losses: increase the energy efficiency of the installation.
• Flame retardant: increases the fire safety of the facility.
• Resistant to microorganisms and fungal growth: ensures hygiene and durability of the installation.
• Completely waterproof: allows use in humid environments.
• Silicone and cadmium free: ensures compliance with environmental standards.
• UV resistance: allows use outdoors (to a limited extent).

The wire meets the IEC 60332-1-2 standard regarding behavior in the event of a fire and has a rated voltage of 600V and a test voltage of 2500V. The insulation resistance is at least 2 GOhm/km, which confirms its high quality of workmanship. The minimum bending radius is 4x the cable diameter for stationary installation and 10x the cable diameter for flexible installation, making it easy to install even in tight spaces.
