A properly selected and constructed lightning protection system protects against electrical discharges and their negative consequences such as fire or electric shock. An important role is played by the lightning wire, which is available in many variants. Find out more about it and see the overview of lightning wires offered by the Onninen installation wholesaler .

What is a lightning wire?
Lightning wire is the basic component used in lightning protection installations. It can function as both a horizontal and vertical air terminal, as well as a discharge air terminal. Additionally, you should pay attention to the very simple construction. Of course, you need to choose models that are durable and resistant to mechanical damage. You can choose models made of galvanized or stainless steel, as well as those made of copper or aluminum alloy. Moreover, it is worth paying attention not only to the price, but above all to the durability of the coating. For example, electrogalvanizing is cheaper than hot-dip galvanizing. The latter provides, for example, greater protection of the installation and resistance to oxidation of the material.
Functions of lightning wire
The lightning wire plays an extremely important role. First of all, it enables the creation of air terminals that protrude above the outline of the protected object. Their task is to directly receive lightning discharges, which is to prevent fires, but also damage to electrical equipment or shocks. You need to know that they can take different forms. These include masts, spiers and even nets or lines. In addition, lightning wire is used for horizontal air terminals. They are used on flat roofs or those with a slight slope. Most often, their diameter is 8 mm. However, vertical air terminals create a protection zone. However, discharge air terminals should provide protection against the impact of surge current. The minimum number of down conductors must correspond to the value resulting from dividing the circuit length by 15. Please remember that the circuit length is expressed in meters, and the number of conductors used cannot be less than 2.
Overview of lightning wires in the Onninen offer
Noteworthy is the ELKO-BIS FI8 aluminum wire . It is a single-core wire with a cross-section of 50.24 mm and a diameter of 8 mm. It is made of semi-hard aluminum. Please note that it does not have high voltage insulation. It can be used both indoors and outdoors, provided it is protected against moisture and corrosion. This wire is suitable for low voltage installations and lightning protection installations, but cannot be used in potentially explosive areas. Through appropriate processing, it can be adapted to the user's needs. Aluminum wire has an advantage over copper wire because it provides the same performance, but is lighter, which is why it works well in modern electrical and lightning protection installations.
You can also choose the ELKO-BIS 3m Terra-Grom earthing electrode , which enables innovative connection of rods via a brass connector. Hot-dip galvanized rods press into the corrugated interior of the sleeve, creating an unbreakable connection. This model uses hot-dip galvanizing to protect the surface.
In the case of a lightning wire mounted on the wall of a facility, you should select a mounting element, i.e. a wire holder with an ELKO-BIS pin . It is attached to the surface by screwing. For horizontal air terminals, it is worth using the ELKO-BIS wire holder with an OC fire rebate . It is used to guide the lightning wire along the lap joints of the roofing sheets.
If it is necessary to straighten the lightning wire manually, use the ELKO-BIS OC wire straightening holder . When installing a lightning wire on the tops of roofs covered with tiles or metal tiles, you will need the ELKO-BIS spring universal ridge tile holder . The wire is attached to the carboy, and the use of a flexible handle allows it to be adapted to most types of carboy. This holder is compatible with 8 mm lightning wire.
The Onninen installation wholesaler's offer also includes lightning wires of smaller and larger diameters. These include Fi 10, Fi 7 or Fi 6 lightning wire. You can choose aluminum or additionally galvanized models. Choosing a model with a raw surface, such as the above-mentioned Elko-Bis wire, will be the best choice due to the possibility of processing and adapting to your needs.
