Some regions have an extremely cold winter and the phenomenon that wires freeze becomes universal, leading to the high rates of accidents, especially frequently happens during the prime time of cold waves, which caused great trouble to the maintenance personnel. Acoustic power is ultrasonic de-icing equipment. After the wires freeze, the tilt angle of wires becomes larger due to the gravity of snow and ice. This variation, however, can be perceived by the Acoustic power through the built-in tilt sensor, therefore transmit high-energy ultrasound to eliminate the stability of the structure of ice on the wires.
