Environment-friendly, high-temperature-resistant and anti-shielding industrial control cable

Abstract

The invention discloses an environment-friendly, high-temperature-resistant and anti-shielding industrial control cable, comprising a cable body that includes conductors, an insulating layer, a shielding layer, an inner sheath and an outer sheath. The conductor is arranged inside the cable body; the section of the conductor is circular in shape; a copper foil layer is extruded outside the conductor; the insulating layer is tightly extruded outside the copper foil layers; the gap part between the insulating layer and the copper foil layers is filled with fillers; the shielding layer is tightly extruded outside the insulating layer; a plurality of uniformly arranged drainage cores are arranged inside the shielding layer; a resin bonding layer is arranged between the shielding layer and the insulating layer; a metal coating is arranged on the outer surface of the shielding layer; a reinforcing layer and a refractory layer are arranged outside the metal coating from inside to outside; the inner sheath is arranged on the outer surface of the refractory layer; the outer sheath is tightly extruded on the surface of the inner sheath. The environment-friendly, high-temperature-resistant and anti-shielding industrial control cable has the advantages of reasonable structural design, long service life and good shielding resistance.

Description

technical field [0001] The invention relates to the field of cables, in particular to an environment-friendly, high-temperature-resistant, and shielding-resistant industrial control cable. Background technique [0002] At present, wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, even in the high-end fields of space and ocean, and cables will be used. With the development of social economy, the varieties of cables are constantly updated and improved, and the production volume It is also increasing continuously. Because of the application of cables in different fields, people's requirements for them are also increasing. The existing cables cannot meet the needs of the industry due to material or structural problems. The Chinese patent literature discloses an application No. CN201320340894.X is a high-temperature-resistant high-shielding environment-friendly cable, which is composed of a conductor, a rubbe...

[0002] At present, wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, even in the high-end fields of space and ocean, and cables will be used. With the development of social economy, the varieties of cables are constantly updated and improved, and the production volume It is also increasing continuously. Because of the application of cables in different fields, people's requirements for them are also increasing. The existing cables cannot meet the needs of the industry due to material or structural problems. The Chinese patent literature discloses an application No. CN201320340894.X is a high-temperature-resistant high-shielding environment-friendly cable, which is composed of a conductor, a rubber insulating layer and an outer sheath. The shielding layer made of zinc-copper wire braided network pipe, but this kind of structural cable cannot meet the needs of existing people due to its unreasonable structural design. In some areas with relatively harsh environments, this structure cannot be well adapted. The service life is short, which brings a lot of inconvenience to the maintenance of the cables in the later stage, and the cost of the enterprise is also greatly increased.
