The breakage of each single core on the cage twisting machine will directly affect the quality of the power optical cable, so a wire break detection mechanism will be installed at the outlet hole of the cage twisting machine. The common wire break detection mechanism of the cage twisting machine currently mainly makes the contact between the contact and the single core. Once the contact fails to contact the single core, an alarm will be triggered, thereby prompting the staff to handle it in time.
