Electrical equipment buildings at the end the low-voltage cables are particular risk of damage caused surges. Suitable lightning and surge protection devices are used compensate the energy from the lightning pulse the entry the building. A direct lightning strike into low- voltage exposed cable data cable can couple high partial light- ning currents adjacent building.TBS Blitzschutz-Leitfaden 2018 / en / 2020/01/10 14:42:40 14:42:40 (LLExport_02613) / 2020/01/10 14:42:54 14:42:54 Danger: lightning impulse and partial lightning currents along wires S3: Direct lightning strike into supply line A direct lightning strike into low-voltage data cable can couple high partial lightning currents an adjacent building.

Distinctions are made between exposed and underground wires, and according the way which the shielding connected the equipotential bond- ing
