Embodiment Construction
[0014] The production method of pre-twisted conductor twisted into cable of the present invention, first twist and twist several conductor cores (single wire cores) into fan-shaped or tile-shaped wire cores in advance according to the cable pitch, and then extrude insulation on the fan-shaped or tile-shaped wire cores layer, and then the fan-shaped or tile-shaped cores after the insulation layer are cabled and twisted into a cable core, and finally the outer sheath is extruded outside the cable core.
[0015] The conductor adopts the pre-twist process. When producing the fan-shaped or tile-shaped cable cores that divide the conductors, the fan-shaped or tile-shaped cable cores can be smoothly combined into a round cable when the cable is formed, and the conductors are eliminated during the cable core compression process. The stress generated by stranding and extension, in the process of compacting and forming the cable core, pre-twisted the formed cable core through the pre-twi...
