Problems solved by technology

For example, the state has made it clear that copper conductors should be used in new residential buildings. There are many types of cables on the market, many specifications, and prices are chaotic. It is very difficult for consumers to choose. As for the quality and length, it is even more difficult for consumers to judge.

Embodiment 1

[0023] A cable production process, comprising the steps of:

[0024] 1) Drawing: At 650°C, the metal conductor is drawn into a wire with a diameter of 1mm;

[0025] 2) Annealing: annealing is carried out through an annealing furnace, the annealing temperature is 550°C, and the annealing time is 50 minutes, to make a monofilament;

[0026] 3) Twisting system: use 3 monofilaments to perform concentric multi-twisting to form a conductive wire core, and use a compactor to interweave and compress the wires in a clockwise direction;

[0027] 4) Coating: The wire core uses an extruder to simultaneously extrude the electrical insulation layer and the flame-retardant insulation layer on the outer surface;

[0028] 5) Brush anti-corrosion material: brush a layer of anti-corrosion material on the outer surface of the cable obtained in step (4), and let it stand for 0.5 hours;

[0029] 6) Forming: 3 conductive wire cores are twisted into a cable without back-twisting, and the cabled cab...

Abstract

The invention discloses a cable production process, and relates to the field of machinery and equipment manufacturing. The cable production process comprises the nine steps of drawing, annealing, stranding, coating, brush coating of anti-corrosion materials, forming, filling, and wrapping. According to the cable production process, the mechanical strength, chemical corrosion resistance, humidity resistance, waterproof performance, flame retardancy and the like of the cable are improved.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a cable production process. Background technique [0002] The cable is made of one or more mutually insulated conductors and an outer insulating protective layer. The wire that transmits power or information from one place to another is a device used to transmit electric energy or control signals. The cable is mainly used for Control device wiring. With the rapid development of power cable buried laying projects, higher requirements are put forward for cables. It is hoped that cables have good insulation performance, high chemical stability, no rust, no aging, and high properties that can adapt to harsh environments, so they are widely used. application. For example, the state has made it clear that copper conductors should be used in new residential buildings. There are many types of cables on the market, many specifications, and prices are chaotic. It is very difficult for ...
