Cable bundling is a process requirement. The cross section and position of the circuit routing should be paid special attention when laying cables, because the cross section of the cable will change due to the change of the cable route. If the cable position is incorrect, it will cause the cable to be laid unsmoothly, affecting the neatness and appearance. In addition, the turns of the relay should be smooth and the curvature radius should be greater than 60mm. If it is less than 60mⅡ, it is easy to damage the cable core wire, especially the large-logarithm cable.
