[0028] In this embodiment, when the cables are sprayed through the liquid collecting box 26, the excess insulating paint falls on the inner wall of the spray box 11, and then flows along the inner wall of the spray box 11 to the inner bottom thereof, and the insulating paint can be transported to the liquid collecting box 26 for collection through the connecting pipe;

[0029] The side of the liquid collecting box 26 is connected with a third connecting pipe 24, one end of the third connecting pipe 24 is connected with the first connecting pipe 15, and valves 8 are provided on the first connecting pipe 15 and the third connecting pipe 24;
