112 provides a set of practical procedures related to the lightning protection, earthing and bonding of radio base stations (RBSs). When lightning strikes a tower, the surge of electricity must be directed away from sensitive equipment and structural. Grounding/earthing, lightning protection and surge protection are critical parts of a telecommunications facility installation. The next few slides are from the papers on their website. Protected lines should not be parallelly. ABB Soulé located in Bagnères-de-Bigorre (South West of France) has several decades of experience, and uses its technological expertise to provide protection against lightning and overvoltage.
