Description

An anti-stretch anti-interference insulated control cable

technical field

The utility model relates to the field of cables, in particular to an anti-stretching and anti-interference insulated control cable.

Background technique

At present, with the development of science and technology, industry and other fields are also developing rapidly. As equipment that is often used in industry, cables are widely used by people. Cables refer to materials used for power, communication and related transmission purposes. With the increase of power, the requirements for cables are getting higher and higher. However, the cables used in the industry have poor anti-interference ability due to their unreasonable structural design, and the cables cannot work normally in harsh environments. work, which brings great losses to the enterprise.

Utility model content

In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a stretch-resistant and anti-interference insulated control cable.

The utility model is realized by adopting the following technical solutions: an anti-stretching and anti-interference insulated control cable, which includes a cable body, the cable body includes a conductor, a shielding layer and an outer sheath, and the inside of the cable body is provided with multiple An isolation bracket; a plurality of conductors are arranged inside the isolation bracket; and a reinforcement layer is arranged outside the conductor; a plurality of polyolefin elastomers are arranged outside the isolation bracket; a shielding layer is arranged outside the isolation bracket ; The shielding layer is extruded with a wear-resistant layer; the wear-resistant layer is extruded with a layer of anti-pressure layer; the anti-pressure layer is extruded with a protective layer; and the protective layer is tightly extruded An outer sheath.

In the above-mentioned stretch-resistant and anti-interference insulated control cable, the cross-section of the isolation bracket provided inside the cable body is a cross-shaped structure.

In the above-mentioned tensile and interference-resistant insulated control cable, a plurality of temperature-measuring optical fibers are arranged inside the wear-resistant layer.

detailed description

As shown in Figure 1, a tensile anti-interference insulated control cable, it includes a cable body 1, the cable body 1 includes a conductor 2, a shielding layer 7 and an outer sheath 12, the inside of the cable body 1 is provided with multiple An isolation bracket 4; a plurality of conductors 2 are arranged inside the isolation bracket 4; and a layer of reinforcement layer 3 is arranged outside the conductor 2; a plurality of polyolefin elastomers 5 are arranged outside the isolation bracket 4; the isolation A layer of shielding layer 7 is arranged outside the support 4; a layer of wear-resistant layer 8 is extruded outside the shielding layer 7; a layer of anti-pressure layer 10 is extruded outside the wear-resistant layer 8; A protective layer 11; and a layer of outer sheath 12 is tightly extruded outside the protective layer 11.

The cross-section of the plurality of isolation brackets 4 provided inside the cable body 1 is a cross-shaped structure, which can fix the conductor 2, prevent the conductor 2 from shifting, and make it more stable; the shielding layer 7 is tin-plated Copper wire and aluminum foil composite tape are mixed and braided, so that the cable has the advantages of small working capacitance, low capacitance unbalance and small distributed inductance; the wear-resistant layer 8 can effectively improve the softness of the cable, so that the cable has a wide range frequent movement; the temperature-measuring optical fiber 9 can send corresponding alarms according to changes in temperature, making the use of the cable safer; the pressure-resistant layer 10 is made of polyurethane foam plastic, thereby forming a plastic foam filling layer, so that The internal structure of the cable is more compact, and it will not break even if it is squeezed; the protective layer 11 can further enhance the twist resistance of the cable body 1, and greatly reduce and disperse the torsional stress of the cable, effectively protecting the The internal structure of the cable body 1.

The above are the embodiments of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of application of the utility model are included in the scope of the patent application of the utility model.
