Towers
Towers
When choosing towers as lightning conductor supports, ‘Self-supporting’ type towers are preferred.
This choice should take into account the following parameters :
The exact location of the installation in order to determine the wind region (department and canton): from region 1 to region 5 and the qualification of the site: Normal or exposed.
Guyed towers are also available, made of hot-dip galvanised metal lattice girders with a triangular cross-section 175 mm apart and round tube members 22 mm in diameter.
Self-supporting towers
All self-supporting towers are fitted with a base plate to be embedded at the same time as the concrete foundation. The sections are connected by bolted plates. The height and number of sections will depend on the height of the tower. All parts of the tower are made of hot-dip galvanised steel.
The choice of material depends on the following parameters and the size of the structure :
-The installation site and therefore the wind region.
-Site characteristics: normal or exposed.
-Type of ground.
The force exerted on the aerials (total force to which the tower is subjected).

Guyed towers
Guyed towers are made of hot-dip galvanised metal lattice girders with a triangular cross-section 175 mm apart and round tube ribs 22 mm in diameter.
They are supplied in 3-metre sections. The sections will be bolted together and fitted with guy wires.
