The cable is usually a rope-like cable made of several or several groups of wires, each group of at least two wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is wrapped with a highly insulating covering layer. The multi-layer co-extrusion method of the cable insulation layer can improve the efficiency of cable production.

[0003] After searching, Chinese patent announcement number CN219476397U discloses a multi-layer co-extruded cable insulation layer extruder, including an extrusion box, a first feed port is fixedly installed at the middle position of one side of the upper end face of the extrusion box, a second feed port is fixedly installed at the middle position of the upper end face of the extrusion box, the first feed port and the second feed port output ends are both through the upper end face of the extrusion box and the ends are through-connected with an extruder, and the inner side wall of the extruder is located between the first feed port and the second feed port and is fixedly connected with a first trapezoidal hollow column. The extruder is designed with a first trapezoidal hollow column and a second trapezoidal hollow column, and the first trapezoidal hollow column and the second trapezoidal hollow column can make the insulation material evenly laid on the outside of the cable, and the insulation material on the outside of the cable is blown dry and cooled by the refrigerator to avoid the possibility that the traditional water cooling may not be flat on the outside of the insulation, and the movable plate is designed to achieve the clamping of cables of different sizes between the first turntable and the second turntable for work.
