A properly selected and executed lightning protection system protects against electrical discharges and their negative consequences in the form of fire or electric shock. An important role is played by the lightning protection wire, which is available in many versions. Learn more about it and get to know the overview of lightning protection wires in the offer of the Onninen installation wholesaler .

What is a lightning wire?
The ground wire is a basic component used in grounding systems. It can function as both a horizontal and vertical air terminal, as well as a discharge terminal. In addition, it is important to note its very simple construction. Of course, you need to choose models that are durable and resistant to mechanical damage. You can choose models made of both galvanized and stainless steel, as well as those made of copper or aluminum alloy. In addition, 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 material oxidation.
Functions of grounding wire
The ground wire plays an extremely important role. First of all, it allows for the construction of air terminals that protrude beyond the outline of the protected object. Their task is to directly receive the lightning discharge, which is to prevent fires, but also damage to electrical equipment or electric shocks. It is important to know that they can take various forms. Among them, we can distinguish masts, spires or even nets or ropes. In addition, the ground 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. Vertical air terminals, on the other hand, create a protection zone. On the other hand, downstream air terminals should provide protection against the impact of surge current. The minimum number of downstream conductors must correspond to the value resulting from dividing the length of the circuit by 15. It is important to remember that the length of the circuit is distinguished in meters, and the number of conductors used cannot be less than 2.

The ELKO-BIS FI8 aluminum wire is worth noting. 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. It should be noted that it does not have high-voltage insulation. It can be used inside a building, but also outside, provided that it is protected against moisture and corrosion. This wire is suitable for low-voltage and lightning protection installations, but it cannot be used in explosion-hazard zones. It can be adapted to the user's needs through appropriate processing. Aluminum wire has an advantage over copper 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 grounding rod , which allows for innovative connection of rods via a brass connector. Hot-dip galvanized rods are pressed into the corrugated interior of the sleeve, creating an inseparable connection. In this model, hot-dip galvanizing is used to protect the surface.
In the case of a ground wire mounted on the wall of the object, a mounting element should be selected, i.e. the ELKO-BIS wire holder with a pin . It is attached to the substrate by screwing. For horizontal air terminals, it is worth using the ELKO-BIS wire holder for a fire OC rebate . It is used to guide the ground wire along the overlap joints of roofing sheets.
If manual straightening of the ground wire is necessary , the ELKO-BIS OC wire straightening holder should be purchased. In the case of mounting the ground wire on the tops of roofs covered with tiles or metal roof tiles, the ELKO-BIS universal spring ridge tile holder will be necessary. The wire is attached to the ridge tile, and the use of a flexible holder allows it to be adapted to most types of ridge tile. This holder is compatible with a ground wire with a cross-section of 8 mm.
In the offer of the Onninen installation wholesaler you can also find grounding wires of smaller and larger diameter. Among them, you can distinguish grounding wire Fi 10, Fi 7 or Fi 6. You can choose aluminum or additionally galvanized models. Choosing a model with a raw surface such as the aforementioned Elko-Bis wire, due to the possibility of processing and adapting to needs, will be the best choice.
