Embodiment 1

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

[0019] 1) Monofilament drawing, under the condition of 38 ℃, using a wire drawing machine, through a drawing die, the copper rod is drawn, and the diameter of the drawing wire is 0.5mm;

[0020] 2) Monofilament annealing, annealing in an annealing furnace, annealing temperature 535 ℃, annealing time 52 minutes, to make monofilament;

[0021] 3) Twisting, use 5 monofilaments for concentric twisting to form a conductive core, and use a compression machine to compress the wire;

[0022] 4) For cabling, twist the 4 conductive cores into cables without back-twisting, and bind the cables after cabling;

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

Embodiment 2

[0024] Example 2: The rest is the same as in Example 1, except that in step 1), the temperature for drawing the monofilament is 30 degrees Celsius, and the diameter of the drawn wire is 0.7 mm, and in step 2), the annealing temperature is 450°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 temperature for drawing the monofilament is 45 degrees Celsius, and the diameter of the drawing wire is 1 mm, and in step 2), the annealing temperature is 580 degrees Celsius, and the annealing time is 60 minutes, In step 5), the thickness of the insulating layer is 2 mm.

[0026] After the above process steps, take out the cable sample, and the tested performance is as follows:

[0027] In the above three embodiments, under the condition of room temperature, the cable works for 1h, the wire body temperature is 20°C, and the wire body temperature is 25°C after 10h. When the temperature is 45°C, the heat dissipation effect of the coaxial cable is better; the curling experiment of the coaxial cable is carried out. The outer sheath is damaged after 20 times of crimping; burn the coaxial cable with a lighter, the coaxial cable will burn after 3 minutes, and the ordinary coaxial cable will catch...

Abstract

The invention discloses a cable production process which includes the steps of firstly, single wire drawing; secondly, single wire annealing; thirdly, stranding; fourthly, cabling; fifthly, coating. The production process is reasonable and simple, and the produced cables are resistant to corrosion and oxidation, long in service life, suitable for various severe environments, free of electric leakage and high in safety performance.

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...
