Device for protecting electric systems, particularly telecommunication systems, against overvoltage pulses

摘要

Device for protecting electric systems, particularly telecommunication systems, against overvoltage, comprising the combination of a tube of conducting material and permitting a passage through the wall with an overvoltage protective circuit placed in the tube and comprising at least two diverting components, in such a way that a voltage peak, even with a steepness of 5kV/nsec, can be diverted step by step.
