PURPOSE: An apparatus for alarming an approach to a power cable is provided to lengthen a lifetime of a transmission and reception power cable by preventing an accident due to the power cable. CONSTITUTION: An apparatus for alarming an approach to a power cable includes a transmission unit and a reception unit. The transmission unit includes a sensor portion(14), a signal processing portion(24), a micro computer control portion(18), and the first RF transmission and reception module. The sensor portion generates a sense signal when a crane approaches a power cable. The signal processing portion amplifies the sense signal and removed the noise from the sense signal. The micro computer control portion generates the distance data by analyzing and processing the distance between the sensor portion and the power cable. The first RF transmission and reception module modulates the distance data to a wire signal or a wireless signal. The reception unit includes the second RF transmission and reception module, a CPU, a sound source output portion, and a lamp indication portion.
