Aluminum overhead conductor – reliability and durability in every installation

This aluminum conductor, with a cross-section of 120 mm², is a robust solution for overhead line construction. Made from aluminum, it features high conductivity and resistance to atmospheric conditions. Its design, based on concentrically stranded multi-wire cores, ensures flexibility and ease of installation, while also enhancing mechanical strength. This conductor is ideal for both professional installers and end customers seeking a reliable power supply solution.

Construction and application – key to efficient operation

The AL conductor is designed for electrical overhead lines. Its construction complies with standard PN-EN 1715-2:2000, guaranteeing safety and long-term operation. Strands twisted in opposite directions minimize the risk of delamination, while the outer layer twisted to the right provides additional protection against mechanical damage. The approximate outer diameter of the conductor is 14 mm, facilitating installation and routing.

Durability and specifications – why choose this conductor?

The AL 120 mm² conductor stands out with a high breaking strength of 17769 N, making it resistant to wind and ice loads. The calculated resistance per kilometer at 20°C is 0.250 Ω, minimizing energy losses during transmission. The conductor weighs approximately 321.2 kg/km – an important factor when planning transport and installation. The conductor structure consists of 19 wires, each with a diameter of 2.80 mm. The absence of an outer sheath or insulation makes this a typical overhead conductor designed for direct exposure to the environment – therefore, proper protection of connections is essential.
