There are too many wires in the line tube, which are prone to heat, causing short circuit and not easy to whip, which is not conducive to subsequent maintenance.
Supervisor reminds that when the wire is used, it will generate a lot of heat. If there is not enough space inside the bushing and there is not enough space for heat dissipation, it will cause potential safety problems. In general, the cross-section of the wire in the sleeve must not exceed 40% of the diameter of the sleeve.
