Accordingly, when the copper bar 1 having the insulator 1a disposed on the outside moves adjacent to the hot air nozzle 32 and passes through the hot air nozzle 32, hot air is sprayed to the insulator 1a to insulate the insulator ( By heat-shrinking from one end to the other end of 1a), it is possible to prevent rapid heat-shrinking in the air outlet part to prevent air from being trapped inside the insulator 1a, and to sweep the air in one direction to the inside of the insulator 1a. air can be removed.

The vision camera 50 is disposed on the top of the heat shrinkable portion 30 into which the bus bar 1 is introduced, and can measure the color and length L of the plurality of insulators 1a. In addition, the vision camera 50 may be connected to the processor 9 and transmit the measured color and length L of the insulator 1a to the processor 9 .

Thereafter, the processor 9 determines the temperature and speed of the hot air sprayed through the hot air nozzle 32 based on the measured colors of the plurality of insulators 1a and the length L of the insulators 1a, and determines the determined The insulator 1a can be thermally contracted with respect to the bus bar 1 by spraying the hot air to the insulator 1a at the temperature and speed of the hot air.

Here, the determined temperature of the hot air is higher when the second insulator 1a-2 is higher than the first insulator 1a-1, and the determined speed of the hot air is higher than that of the first insulator 1a-1 in the second insulator 1a-2. ) can be faster.

Accordingly, efficient heat shrinkage of the insulator 1a can be implemented by providing hot air at a temperature and speed suitable for the insulator 1a of various colors and sizes according to the use environment of the copper subbar 1.
