On the other hand, when at least one of the first sensor unit 61, the second sensor unit 62, and the seventh sensor unit 67 is sensed simultaneously or sequentially, the control unit 90 controls the other side cleaning nozzle based on the initial reference position. Only the portion 34 is moved (eg in the negative direction). Accordingly, by allowing the two catenary lines 200 to be positioned between each washing nozzle part 34 in the crossing section, washing of each catenary line 200 can be performed.

In addition, the control unit 90 controls the washing heating unit 36 to heat the washing water in the catenary washing process as described above, thereby spraying high-temperature washing water onto the catenary 200 or insulator, or the washing detergent unit 37.
