Single-core PTFE wire HELUFLON®-PTFE-5Y 1xAWG28/7 (0.09 mm²) blue, 1000 V 25333

PTFE cable for extreme conditions

This high-quality HELUFLON-PTFE-5Y cable, catalog number 25333, is a specialized solution for applications requiring exceptional resistance to external factors. This cable is distinguished by a wide range of operating temperatures and resistance to aggressive chemicals, making it an ideal choice for harsh industrial conditions.

Construction and properties

The cable is characterized by a construction that ensures reliability and durability. Its copper core is silver-plated, which improves conductivity and corrosion resistance. Insulation made of PTFE (polytetrafluoroethylene) – HELUFLON® – guarantees excellent dielectric properties, thermal resistance and chemical resistance. PTFE meets the requirements of DIN VDE 0207 part 6 and MIL-W 16878 standards. In addition, the materials used in production do not contain silicone, cadmium or substances that interfere with painting.

It is worth paying attention to a number of important properties of this cable:

• High insulation resistance minimizes the risk of breakdown and ensures safe use.
• Low electrical losses translate to energy efficiency of the installation.
• The non-flammability of the cable increases fire safety.
• Resistance to microorganisms and fungal growth ensures hygiene and durability in demanding environments.
• Complete resistance to ozone and atmospheric conditions guarantees reliability in outdoor applications.
• Minimal water absorption protects against damage caused by moisture.

Applications and technical parameters

The HELUFLON-PTFE-5Y cable is used in installations and construction of switchgear cabinets operating in extreme thermal conditions, such as furnaces, brick factories, kitchen and measuring devices. It is also ideal in the chemical industry due to its resistance to flames, acids, alkalis, solvents, oils and gasoline. It meets the requirements of the Low Voltage Directive 2014/35/EU (CE marking).

Key technical parameters:

• Operating temperature range: from -190°C to +260°C (short-term up to +300°C).
• Operating voltage: type E = 600V; type EE = 1000V.
• Test voltage: type E = 3.4kV; type EE = 5kV.
• Insulation resistance: min. 1 GOhm x km.
• Minimum bending radius: 10 x Ø cable.
• Radiation resistance: up to 1 x 10⁵ cJ/kg (up to 1 Mrad).

Available cable colors are indicated by symbols added to the catalog number: 1 – black, 2 – red, 3 – blue (as in this particular product), 4 – brown, 5 – white, 6 – transparent, 7 – two-color and 8 – other colors on request. The core can also be supplied bare, tinned or nickel-plated (on request).
