Lightning conductors

The lightning conductors purpose is to protect buildings and open areas against direct impact of lightning.
The conduction of the electric discharge to earth avoids the damage, linking the flow of current through its own structure.
Predominantly there are three different types of installations:

	Active Lightning Conductors (ALC).
	Meshed Cage lightning conductor (Faraday).
	Taut wire lightning conductors.

Active Lightning Conductors (ALC).

The Active Lightning Conductor is an improved version of the single lightning rod benefiting from the latest developments in lightning protection, conform to IEC-ENV 61.024.

The ALC used by our company, in collaboration with research centres, and first producers, is built by a single rod equipped with a structure that generates the upward leader that shall meet the lightning.

Its autonomy and simplicity of mounting, more precise and controlled, its wider protection radius, place them on a privileged position to be chosen before others.

Conforming to the specific standards IEC-ENV 61.024, an installation is composed by:

One Active Lightning Conductor (ALC) accredited conform to standards, mounted on an elevation pole.
One or two down conductors linking the Active Lightning Conductor to earth.
One or two earthing points to channel and dissipate the lightning current.


Buildings	Industrial plants	Dangerous materials tanks	Transmission towers	Open areas

Meshed Cage lightning conductor (Faraday).

The Meshed Cage consists of a conductive network situated on the external part of the building to protect

A conductive cage is situated on the roof with a series of small Franklin rods.

It is connected to the ground by down conductors. Each down conductor has its own separate earthing point, and these in turn are interconnected by an under-soil ring.

The number of down conductors and earthing points gives this system a great protection guarantee against electromagnetic fields.

This installation must be conform to IEC-ENV 61024 standards.

Taut wire lightning conductors.

This system of taut wires is used for singular buildings with a strange or irregular architecture or in open areas.

Qualified us “isolated” of the protected structure, consists in stretching a number of conductive wires over the area to be protected fixed on independent posts.

The dimension of the netting is defined by application of the electromagnetic model (theory of the fictitious sphere).

The different dispositions to apply must be conform to IEC-ENV 61024 standards.
