A line trap is a set of physically-large inductors often seen hanging from transmission towers at the end of a high-voltage transmission line, where the line terminates at a substation. As transmission lines often carry data signals, which operate at frequencies very much higher than the 50-Hz (or 60-Hz) power frequency, the high inductive reactance* of the line traps act to prevent these signals from continuing beyond the end of that section of transmission line, while having an insignificant effect on the power-frequency load current.

(*Inductive reactance is directly proportional to frequency)
