The degree risk depends how the lines are
routed.
A direct lightning strike into low-
voltage exposed cable data
cable can couple high partial light-
ning currents adjacent
building. Suitable lightning and surge protection devices
are used compensate the energy from the lightning
pulse the entry the building.TBS
