Single-core FEP wire, resistant to high temperatures HELUFLON®-FEP-6Y 1x4 mm² blue, conductor: tinned copper 25583

High-temperature single-core wire – reliability in extreme conditions

This HELUFLON®-FEP-6Y single-wire cable is a specialized solution for installations requiring resistance to high temperatures and aggressive chemical environments. Made of tinned copper and insulated with FEP fluoropolymer, it ensures reliable operation even in the most extreme conditions. The cable is ideal for both professional installers and end-users looking for a durable and safe solution.

Construction and application

This cable stands out with its construction designed for demanding applications. The copper core, coated with tin, guarantees good conductivity and corrosion resistance. The FEP (fluoropolymer) insulation provides exceptional thermal resistance – from -100°C to +205°C (short-term up to +230°C) – and chemical resistance. This makes it suitable for:

• installations in furnaces, brickworks and heating devices,
• kitchen and measuring devices,
• chemical industry (resistant to alkalis, acids, food, oils and gasoline),
• construction of switchgear cabinets in difficult industrial conditions.

Additionally, the cable is characterized by low dielectric losses and is flame retardant, which increases safety.

Key features and benefits

• Exceptional thermal resistance: temperature range from -100°C to +205°C (short-term up to +230°C) allows the cable to be used in high-temperature applications.
• Chemical resistance: FEP insulation provides resistance to a wide range of chemicals, including alkalis, acids, oils and gasoline.
• High quality workmanship: tinned copper core guarantees good electrical conductivity and long-lasting reliability.
• Safety: flame retardant insulation minimizes the risk of fire.
• Flexibility: class 5 core (multi-strand flexible) makes installation and routing of cables in tight spaces easier.
• Minimum bending radius: flexible 10x cable diameter, stationary 4x cable diameter facilitates installation even in difficult conditions.
• Compliance with standards: the cable meets the requirements of the Low Voltage Directive 2014/35/EU.

The core cross-section of 4 mm² and the rated voltage of 600 V (U/U0) make this cable suitable for many electrical applications requiring high reliability and safety. The outer diameter of the cable is approximately 3.4 mm.
