The present invention relates to an apparatus for preventing theft of a temporary cable for preventing the theft of the temporary cable to be installed temporarily at a construction site. According to the present invention, the apparatus for preventing theft of the temporary cable includes: a first branch line (BL1) which is connected to a power interruption detecting unit (10); and a second branch line (BL2) which is connected to a battery charging unit (20). The present invention maintains a charging state that a first switch (11b) of a relay (11) is turned on and a second switch (11c) is turned off by applying an AC power to a solenoid unit (11a). An alarm circuit connected to the second switch (11c) forms a closed circuit as the first switch (11b) of the relay (11) is turned off and the second switch (11c) is turned on if the current to be supplied to the solenoid unit (11a) of the relay (11) is blocked. |
