Lightning protection aluminum wire Ø10, 4.76m = 1kg /20kg/ FI10 AL.

Application in Lightning Protection Systems

This aluminum conductor with a diameter of 10 mm is a key component of lightning protection systems, designed to safely conduct lightning current to ground. Thanks to the use of pure aluminum (Al 99,7), the product ensures high electrical conductivity while maintaining a relatively low self-weight, facilitating installation on building facades or roofs. Its construction allows for the safe transmission of high current intensities during atmospheric discharges, protecting infrastructure from damage.

It is important to note the specific characteristics of this material – although aluminum is lighter than copper, it requires proper handling at points of contact with other metals to avoid galvanic corrosion. In the case of this wire, its 10 mm thickness corresponds to the protection class required for standard lightning protection installations, as confirmed by standards PN-EN 62305-3:2011 and PN-EN 62561-2:2018-04. For the installer, this means certainty that the material meets rigorous safety and durability requirements.

Benefits and Construction Features

Choosing an aluminum wire with a cross-section of 10 mm brings specific benefits both during installation works and in the long-term operation of the system:

• Optimal weight-to-strength ratio – with a mass of approximately 0.21 kg per running meter (yielding approx. 4.76 m per kilogram), the material is easy to transport and lay, without excessively loading roof or wall structures.
• Compliance with standards – the product has been manufactured in accordance with European standards for lightning protection systems (LPS), which is essential during installation inspections by fire safety experts.
• Material durability – the high purity of aluminum (99.7%) ensures resistance to atmospheric conditions and surface oxidation, which forms a protective layer.
• Dimensional precision – a cutting tolerance of +/-3% allows for accurate planning of segment lengths required for project implementation without significant material waste.

Parameters such as a conductor diameter of 10 mm and material Al 99,7 are crucial for the proper functioning of the system. The linear weight slightly exceeds 0.2 kg/m (exactly approx. 0.21 kg/m), meaning that from one kilogram of material, approximately 4.76 meters of wire are obtained. The entire product has been designed in accordance with the requirements of standards PN-EN 62305-3:2011 and PN-EN 62561-2:2018-04.

Installation and Practical Usage Aspects

During wire installation, it is necessary to maintain electrical continuity and secure the conductor with insulating supports at intervals specified by relevant standards. Thanks to its 10 mm diameter, this conductor is sufficiently rigid to maintain a straight line even over larger spans between mounting points, simplifying the installer's work and improving the aesthetics of the finished installation. However, it does not require specialized cutting tools – standard pliers or metal shears are sufficient for precisely cutting segments to the required length.

This material is typically sold per running meter or in net kilograms (depending on the chosen sales unit), facilitating cost calculation for the entire lightning protection project regardless of the building size. Thanks to this solution, the quantity of purchased material can be easily adjusted to the actual needs of new construction or the modernization of existing installations.
