Pipe-through cable capable of monitoring sinking

The utility model relates to a pipe-through cable capable of monitoring sinking. The pipe-through cable comprises a pipe-through cable body (1) and a conjunction box connected with the pipe-through cable body (1); and is characterized in that a micro stroke switch is mounted outside the conjunction box, the trigger end (3) of the micro stroke switch is connected with a standby core (2) in the pipe-through cable body (1), and the signal output end of the micro stroke switch is connected in series between a dc power supply and a voice alarm module, so that the micro stroke switch can emit voice prompt when being triggered. It is provided that sinking of the pipe-through cable can be effectively monitored, and damage on external insulation or loosening of the binding posts due to sinking can be timely discovered at an early stage, thereby improving operational reliability of equipment, and avoiding misoperation of a power system protector caused by sinking of the pipe-through cable.
