These 3 main parts are the components of the lightning protection
system.
This conductor will usually run outside the structure.Each fixing
should allow an eventual conductor dilatation.Bend radius have to
be inferior to 0.2 meters.Metalli-cal masses situated in the zone
of separation calculated beforehand will be interconnected
equipotentially to the lightning conductor.Each down conductor will
be equipped at the bottom with a control junction and a 2
meter-high mechanical protective tube.
The capturing device with its supporting mast and fixings. .The
down conductor composed of one or several tin-ned copper tape with
section in compliance with stan-dards in force,designed to flow the
lightning current of the lightning conductor to the earthing
system.
The earthing system with an adapted form in com-pliance with
standards in force has for aim to diffuse the lightning current to
the ground.An inspection pit will be installed to do the
equipotential connection with the nearest electrical earth netword
of the building. Installation quality of a lightning system is an
impor-tant element ofr the efficiency of a lightning protection
system. For each installation and in most of cases it will be
bet-ter to start with the installation of the earthing
sys-tems,then as direct as possible channels of each down
conductor,then finish with the lightning conductor and roof circuit
installation.
