A direct lightning strike into low-
voltage exposed cable data
cable can couple high partial light-
ning currents adjacent
building. Electrical equipment buildings at
the end the low-voltage cables are particular risk
of damage caused surges.TBS

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.
The degree risk depends how the lines are
routed. Distinctions are made between exposed and
underground wires, and according the way which
the shielding connected the equipotential bond-
ing. Suitable lightning and surge protection devices
are used compensate the energy from the lightning
pulse the entry the building
