Problems solved by technology

However, the cable industry has been facing a series of problems such as short service life of cables and energy shortage.
The application number is 201310127354.8, which discloses a photovoltaic cable and its production process. The photovoltaic cable is characterized in that it is processed through the steps of regular stranding, extruded electrical insulation layer, flame-retardant insulation layer and sheath. The cable has Excellent heat resistance, cold resistance, ultraviolet resistance, ozone resistance and weather resistance, low smoke and halogen free, low toxicity, flame retardant, but the cable is easy to corrode, has a short service life, low applicability, and is not easy to promote and use

Embodiment 1

[0022] The production process of a kind of electric cable of present embodiment, its process step is as follows:

[0023] (1) Material selection; aluminum wire, cross-linkable polyolefin base material, FPV series cross-linkable polyolefin base material, epoxy-phenolic paint;

[0024] (2) Twisted wires; every 4 copper wires selected in step (1) are twisted together in a normal concentric strand twisting method to make a conductor core;

[0025] (3) armoring; wrapping a layer of steel strip outside the conductor core obtained in step (2);

[0026] (4) Extrude the electrical insulation layer and the flame-retardant insulation layer; use the extruder to simultaneously extrude the electrical insulation layer and the flame-retardant insulation layer on the outer surface of the wire core processed in step (3), and keep the temperature at 150°C. The components and mass percentages of the flame-retardant insulating layer are: 60% of cross-linkable polyolefin base material; 10% of ultr...

Embodiment 2

[0029] Example 2: The rest is the same as that of Example 1, except that in step (4), the temperature is kept at 170°C, the thickness of the electrical insulation layer in step (4) is 1.5mm, the thickness of the flame-retardant insulation layer is 3mm, and the radiation According to the thickness of the cross-linked flame-retardant polyolefin sheath is 5 mm, in step (4), the flame retardant is magnesium hydroxide.

[0030] Example 1 Example 2 Example 3 extrusion time 30min 25min 15min Heat resistance 100℃ 110℃ 113.5℃

[0031] Through the above three examples, it can be seen from the three sets of data in the above table that when the temperature is controlled at 180°C, the cable extrusion molding time is the shortest, the thickness of the electrical insulation layer is 3mm, the thickness of the flame-retardant insulation layer is 5mm, and the irradiation cross The thickness of the joint flame-retardant polyolefin sheath is 1Omm, and th...

Abstract

The invention discloses a production technology of a cable. The technical steps of the production technology of the cable are material selection; wire twisting; armoring; extrusion of an electrical insulating layer and a flame-retardant insulating layer; brush coating of anticorrosion material; and manufacturing of a sheath. The production technology of the cable is reasonable and concise in technology. The cable is corrosion-resistant, oxidation-resistant, long in the service life and suitable for various severe environments without the phenomenon of electric leakage so that safety performance is high.

Description

Technical field [0001] The invention involves the production process of electrical machinery and equipment manufacturing, especially the production process of a cable. Background technique [0002] The wire and cable industry is the second largest industry in China after the automotive industry. The satisfaction rate of product variety and domestic market share exceeded 90%.In the world, the total output value of China's wire and cable has exceeded the United States and has become the world's largest wire -cable producer.With the rapid development of China's wire and cable industry, the number of new companies has continued to rise, and the overall technical level of the industry has been greatly improved.However, the cable industry has always faced a series of problems such as short life life and shortage of energy.The application number was 201310127354.8 an open photovoltaic cable and its production process. The photovoltaic cables are characterized by the processed systemExce...
