Single-core PTFE wire HELUFLON®-PTFE-5Y 1xAWG18/7 (0.90 mm²) black, 1000 V 25421

High-temperature cable for extreme conditions

This specialized HELUFLON-PTFE-5Y T.EE cable, catalog number 25421, is a reliable solution for installations requiring resistance to extreme temperatures, aggressive chemicals, and harsh environmental conditions. Made from high-quality materials, it ensures safe and long-lasting operation in the most demanding applications. The cable is designed to operate at a voltage of 1000V.

Construction and properties

The cable is characterized by a construction that provides exceptional durability and reliability. Its copper core is silver-plated, which improves conductivity and corrosion resistance. The insulation made of PTFE (polytetrafluoroethylene) – HELUFLON® – guarantees resistance to high temperatures (up to +260°C, briefly even +300°C) and aggressive chemical substances, such as acids, alkalis, solvents, oils and gasoline. Additionally, PTFE provides excellent dielectric properties and minimal water permeability. The cable is non-flammable and resistant to the development of fungi and microorganisms.

• Silver-plated copper core ensures excellent conductivity and connection durability.
• PTFE-HELUFLON® insulation guarantees resistance to extreme temperatures and aggressive chemicals.
• Wide operating temperature range from -190°C to +260°C (briefly +300°C) allows use in the most difficult conditions.
• High resistance to radiation up to 1 x 10⁵ cJ/kg (up to 1 Mrad).
• Minimum bending radius 10 x cable diameter facilitates installation even in tight spaces.
• Self-extinguishing and flame-retardant material – meets standards DIN VDE 0482-332-1-2, DIN EN 60332-1-2 and IEC 60332-1.
• Silicone and cadmium free ensures safety for the environment and health.

Applications

The HELUFLON-PTFE-5Y T.EE cable finds wide application in various industries:

• Installations in furnaces and heating devices: thanks to its high temperature resistance, it is ideal for operation in the immediate vicinity of heat sources.
• Chemical industry: resistance to aggressive chemicals makes the cable indispensable in environments exposed to acids, bases and solvents.
• Construction of switchgear cabinets: ensures safe and reliable connections in electrical installations operating in difficult industrial conditions.
• Measuring devices: stability of electrical parameters guarantees precise measurements even at extreme temperatures.
• Food industry: materials used in production are neutral to food and do not contain harmful substances.

Available cable colors: black (standard), red, blue, brown, white, transparent, two-color and others – on request (please add the appropriate symbol to the catalog number). The core can be bare or tinned/nickel-plated (on request).
