Protection against lightning
Effective, fully secure installations
For 10 years, Bodet Campanaire has worked in lightning protection using surge arresters and lightning rods. Today, hundreds of sites have been protected by our experts. Each intervention is a unique experience for the towns and villages using our services.
How does lightning form?
When there is instability and humidity in the air, thunderstorms form. This phenomenon is linked to one type of cloud in particular: cumulonimbus. Even a small thunderstorm can lead to rain and lightning strikes.
Static electricity accumulates in the cumulonimbus clouds. A difference in potential then exists between the cloud and the earth.
A downward lightning bolt with several streamers forms.
A very high-voltage electrical discharge forms, and passes through the air to meet the ground via the shortest route possible.
The current dissipates into the ground.
The sound of thunder is caused by the sudden heating of the air.

Average discharge current: 35,000 A
Maximum allowable current for humans: 0.03 A
Impact temperature of a lightning bolt: 27,000 °C
