step three, cabling is assembled; arranging two control wire core groups 200 and three power wire cores 100 according to five equal parts, filling a central reinforcing member 300 in the middle, enabling the cabling pitch diameter ratio to be not more than 10 times, and uniformly coating talcum powder in the cabling process to form a cable core;
step four, extruding the inner sheath 400 outside the cable core; the inner sheath 400 is made of polyurethane elastomer material with high and low temperature resistance, acid and alkali resistance, oil resistance, flame retardance, super wear resistance and tensile strength, and the thickness is 1.0-1.5 mm. Extruding the inner sheath 400 by adopting an extruding machine, wherein the fixed diameter length of an extrusion die sleeve is 3mm, and the angle difference between die core die sleeves is more than 45 degrees, so that the inner sheath material can be completely extruded into a gap of a cable core, and the cable is more compact and is not easy to deform in the moving and winding process; because the polyurethane elastomer material is easy to absorb water and damp, after being damped, the polyurethane elastomer material is extruded out and easily generates a large number of air holes, and the tensile property of the inner sheath is influenced. Therefore, the raw materials are dried before production, the drying temperature is 80 ℃, and the time is not less than 4 hours. Because the melting temperature of the insulating layer of the wire core is equivalent to the melt temperature of the inner sheath, the phenomenon that the inner sheath and the insulating layer are adhered together is easily generated after extrusion, and therefore, the static powder coating device is required to be adopted to coat the talcum powder once again before the cable core enters the extruder. The electrostatic powder coating device can blow away fine talcum powder particles in the air and make the talcum powder particles carry static electricity, and the talcum powder is uniformly adsorbed on the surface of the cable due to the electrostatic action when the cable core passes through, so that the inner protection layer and the insulating layer of the cable cannot be adhered on the one hand, and on the other hand, the bulge and the broken hole caused by the excessive inner protection process of the talcum powder coating are avoided.
Step five, weaving a reinforcing layer 500 outside the inner sheath 400; the reinforced layer adopts a high-speed braiding machine to braid the aramid fiber wire braided layer, the braiding density is not less than 60%, and the integral tensile and torsion resistance of the cable is improved.
And step six, extruding the outer sheath 600 outside the reinforcing layer 500. The outer sheath 600 is made of a polyurethane elastomer material with high and low temperature resistance, acid and alkali resistance, oil resistance, flame retardance, super wear resistance and tensile strength, the thickness is 2.5-4.0 mm, the outer sheath 600 is extruded by a plastic extruding machine, the fixed diameter length of an extrusion die sleeve is 4mm, the angle difference between the die core die sleeves is larger than 45 degrees, and in order to reduce aramid fiber yarn traces on the surface of a finished cable, the size of the die sleeve is required to be consistent with the outer diameter of a finished product.
And because the processing temperature zone of the polyurethane elastomer material is narrower, the higher the temperature is, the better the melt flow is, when the temperature is too high, the outer sheath extruded on the cable core is easy to droop to cause the core deviation or the out-of-round of the cable sheath when the outer sheath is not cooled. Therefore, the extrusion temperature must be strictly controlled during extrusion, and the extrusion temperature in each zone is as shown in Table 1.
