Embodiment 1

[0018] Example 1: A cable production process, characterized in that: comprising the following steps:

[0019] 1) Monofilament drawing, under the condition of 38°C, use a wire drawing machine to pass through a drawing die to draw the copper rod, and the diameter of the drawn wire is 0.5mm;

[0020] 2) Monofilament annealing, annealing by annealing furnace, annealing temperature 675°C, annealing time 52 minutes, to make monofilament;

[0021] 3) Twisting system, use 5 monofilaments to carry out concentric multi-twisting to form a conductive wire core, and use a compactor to compact the wire;

[0022] 4) Cabling, 4 conductive wire cores are twisted into cables without back twisting, and the cables after cabling are bound;

[0023] 5) Covering, covering the outer side of the cable with an insulating layer. The thickness of the insulating layer is 1mm. The inner side of the insulating layer is provided with an inner sheath. The inner sheath includes an extruded inner sheath and a...

Embodiment 2

[0024] Example 2: The rest is the same as in Example 1, except that in step 1), the temperature of monofilament drawing is 40 degrees Celsius, and the diameter of the drawn wire is 0.7mm; in step 2), the annealing temperature is 650°C, and the annealing time is 40 minutes , step 5), the thickness of the insulating layer is 1.5mm.

Embodiment 3

[0025] Example 3: The rest are the same as in Example 1, except that in step 1), the drawing temperature of the monofilament is 55 degrees Celsius, and the diameter of the drawing is 1 mm; in step 2), the annealing temperature is 680° C., and the annealing time is 60 minutes. In step 5), the thickness of the insulating layer is 2mm.

[0026] After the above process steps, the cable samples are taken out, and the tested performance is as follows:

[0027] In the above three embodiments, under room temperature conditions, the cable works for 1 hour, the temperature of the wire body is 20°C, and the temperature of the wire body is 25°C after 10 hours. The temperature is 55°C, the heat dissipation effect of this coaxial cable is better; the coaxial cable is subjected to crimping experiments, and the bending angles of this coaxial cable are 15°, 40°, and 20°, while the bending angle of ordinary coaxial cables is >55°, The outer sheath is damaged after crimping 20 times; use a li...

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a cable production process. Background technique [0002] The conventional production process of the insulation layer and outer sheath of the cable adopts the insulation extrusion / wrapping and sheath extrusion process. The production process is relatively complicated, the production process is difficult to control, and there are defects such as material loss and equipment investment. The production process is more complicated and difficult to control. The reason is that the conventional process is insulation and sheath extrusion. High temperature resistant materials such as polytetrafluoroethylene require a high temperature extrusion production line. The production process is complicated and difficult to control, and for larger diameter wires Cable production is more difficult, and large-diameter cables produced by extrusion are less flexible. [0003] In addition, the Chinese...
