Lightning protection

Go to to devices that are part of the capture system of an LPS:
- Active electronic lightning rods with Early Streamer Emission (ESE) devices, to NFC 17-102, CTE SU8, UNE 21186.
- Air terminals (Faradization - passive) to IEC 62305.
- Masts and anchorages.

Use Nimbus® Project to work out what lightning rod you should install.

Early streamer emission (ESE) lightning rods

Lightning rod with streaming device (ESE). Early streamer: 15, 30, 45 and 60 μs. NF C 17-102:2011, UNE 21186:2011 y CTE SU 8.

Air terminals

Franklin type lightning air terminal rods, AISI 316 stainless steel (with adapt. piece).


Piece that connects the lightning rod to the down conductor.

Masts and mast anchorages

To give the lightning rod the necessary hight that ensures coverage of the required radius. Fixings for walls or bridges.
A down conductor system should be composed of all the necessary components to discharge lightning energy to ground in a controlled and safe way.


Cable brackets

To fix the down conductor in all its trajectory and avoid any movement.

Down conductors

Conducting element destined to conduct the lightning current from the rod to the ground.

Connecting sleeves

To disconnect the grounding system and measure the reistance.

Protection pipe

To avoid mechanical shocs against the down conductor.

Spark gaps

The grounding system is essential for the proper operation of the LPS and should be made up of all the components needed to dissipate lightning and surge currents.


Earth electrodes

Ground connection and equipotentiality

Earth enhancing compounds

Composites that increase the level of soluble salts in the ground.
It is essential to properly maintain all lightning protection systems. In fact, certain components may lose their effectiveness over time due to corrosion, inclement weather, mechanical shock and lightning strikes. To satisfy the requirements of the standards, the mechanical and electrical characteristics of a lightning protection system must be maintained over its entire life.

Lightning discharge counters

Lightning discharge counters.

Maintenance testers

Devices that check the status of the early streamer emission circuit as well as the equivalent degree of protection of the lightning rod
Nimbus lightning rod tester for testing the early streamer emission internal circuit as well as the level of protection of the lightning rods.
