Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable technology, specifically a composite high-temperature resistant control cable. Background Technology
[0002] As a critical transmission medium, control cables are experiencing rapid growth in demand across industries such as industrial automation, robotics, smart grids, rail transportation, and petrochemicals. However, traditional control cables have significant shortcomings in areas such as interference resistance, bending resistance, high-temperature resistance, corrosion resistance, and intelligent monitoring, making it difficult to meet the high standards required by modern industry.
[0003] The control cable products on the market today generally have several prominent technical bottlenecks. In terms of electromagnetic compatibility, traditional cables have insufficient anti-interference capabilities, making it difficult to meet the increasingly complex electromagnetic interference (EMI) protection requirements in modern industrial environments. Conventional cables have limited bending and torsional resistance, and are also insufficient in their ability to withstand harsh environments such as extreme temperatures, corrosive media, and ultraviolet radiation.
[0004] To address the above issues, a composite high-temperature resistant control cable is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a composite high-temperature resistant control cable to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A composite high-temperature resistant control cable includes several sets of conductors, with a semiconductor shielding layer wrapped around the outer circumference of each conductor. The outer wall of the semiconductor shielding layer is attached to the inner wall of a nanocomposite insulation layer, and a shock-absorbing element is provided on the outer wall of the nanocomposite insulation layer.
[0008] The heat-resistant component includes a carbon fiber protective layer and a water-blocking buffer layer. The carbon fiber protective layer is disposed on the outside of the nanocomposite insulation layer, and the water-blocking buffer layer is disposed inside the carbon fiber protective layer. The nanocomposite insulation layer is located inside the water-blocking buffer layer, and the outer circumferential wall of the carbon fiber protective layer is wrapped with a fluoroplastic heat-resistant layer.
[0009] The water-blocking buffer layer contains several sets of intelligent optical fibers.
[0010] In one alternative: a sheath is provided on the outside of the fluoroplastic heat-resistant layer.
[0011] In one alternative: a group of the conductors is located at the center, and the other conductors are distributed in a circumferential array along the axis of the central group of conductors.
[0012] In one alternative: the outer wall of the smart optical fiber is in contact with the outer wall of the nanocomposite insulation layer.
[0013] In one alternative: the smart optical fibers are distributed in a circumferential array along the conductor axes located in a central group.
[0014] In one alternative: the outer wall of the remaining nanocomposite insulating layer is in contact with the inner wall of the carbon fiber protective layer.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This invention incorporates a semiconductor shielding layer, a nanocomposite insulation layer, intelligent optical fibers, and a withstand component. The semiconductor shielding layer provides electromagnetic interference immunity, preventing insufficient interference resistance in cables and ensuring their long-term stable operation under complex electromagnetic environments. The intelligent optical fiber utilizes distributed fiber optic sensing and MEMS vibration monitoring for real-time status awareness. The withstand component is designed to withstand extreme temperatures, corrosive media, underwater or humid environments, and ultraviolet radiation, enhancing its resilience.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-3 In this embodiment, a composite high-temperature resistant control cable includes several groups of conductors 101. The outer circumferential wall of the conductors 101 is wrapped with a semiconductor shielding layer 102. The outer wall of the semiconductor shielding layer 102 is attached to the inner wall of the nanocomposite insulation layer 103. The outer wall of the nanocomposite insulation layer 103 is provided with a withstand member.
[0025] The semiconductor shielding layer 102 can provide electromagnetic interference resistance, avoiding the situation where the cable's interference resistance is insufficient and affects the cable's use. The nanocomposite insulation layer 103 can improve the cable's insulation strength, temperature resistance and mechanical properties, while suppressing partial discharge.
[0026] The protective component includes a carbon fiber protective layer 104 and a water-blocking buffer layer 106. The carbon fiber protective layer 104 is disposed on the outside of the nanocomposite insulation layer 103, and the water-blocking buffer layer 106 is disposed inside the carbon fiber protective layer 104. The nanocomposite insulation layer 103 is located inside the water-blocking buffer layer 106. The outer circumferential wall of the carbon fiber protective layer 104 is wrapped with a fluoroplastic heat-resistant layer 107 to form a multi-layer composite protective structure. The carbon fiber protective layer 104 can improve the cable's bending resistance and torsion resistance, ensuring long-term stable operation in complex electromagnetic environments. The water-blocking buffer layer 106 can prevent the nanocomposite insulation layer 103 from getting damp, which could lead to a decline in electrical performance. At the same time, for cables laid on the seabed or in humid environments, it can prevent long-term moisture intrusion that may cause corrosion or short circuits. The fluoroplastic heat-resistant layer 107 can ensure the insulation stability and long-term reliability of the cable under extreme temperatures.
[0027] The water-blocking buffer layer 106 is equipped with several sets of intelligent optical fibers 105. The intelligent optical fibers 105 integrate distributed optical fiber sensing and MEMS vibration monitoring to realize real-time status perception and facilitate monitoring.
[0028] The outer side of the fluoroplastic heat-resistant layer 107 is provided with a sheath 108. By providing the sheath 108, the cable can be effectively protected from mechanical wear, oil corrosion and environmental erosion.
[0029] A group of conductors 101 is located at the center, and the other conductors 101 are arranged in a circular array along the axis of the group of conductors 101 located at the center.
[0030] The outer wall of the smart optical fiber 105 is in contact with the outer wall of the nanocomposite insulating layer 103.
[0031] The smart optical fibers 105 are arranged in a circular array along the axis of the conductors 101 located in the central group.
[0032] The outer wall of the remaining nanocomposite insulation layer 103 is in contact with the inner wall of the carbon fiber protective layer 104. By setting the carbon fiber protective layer 104, the bending resistance and torsion resistance of the cable can be improved, and it can adapt to harsh environments such as extreme temperatures, corrosive media, and ultraviolet radiation, thereby improving its tolerance.
[0033] The working principle of this utility model is as follows: the semiconductor shielding layer 102 can provide electromagnetic interference resistance, avoiding the situation where the cable's interference resistance is insufficient and affects the cable's use; the intelligent optical fiber 105 integrates distributed optical fiber sensing and MEMS vibration monitoring to realize real-time status perception; the carbon fiber protective layer 104 can improve the cable's bending resistance and torsion resistance, and can adapt to harsh environments such as extreme temperatures, corrosive media, and ultraviolet radiation, improving its tolerance; ensuring long-term stable operation in complex electromagnetic environments; the water-blocking buffer layer 106 can prevent the nanocomposite insulation layer 103 from getting damp, which would cause a decline in electrical performance. At the same time, for cables laid on the seabed or in humid environments, it can prevent long-term moisture intrusion that may cause corrosion or short circuits.
