Description

Technical Field

[0001] This application belongs to the field of new cable production technology, specifically relating to a new type of composite stranded intelligent conductor for cables. Background Technology

[0002] In existing technologies, twisted-structure smart conductors play a vital role in electrical engineering, effectively transmitting electrical energy and signals, and are widely used in power systems, communication networks, and electronic equipment. However, current twisted-structure smart conductors on the market have some shortcomings.

[0003] In existing technologies, traditional twisted-strand smart conductor structures mostly use a single conductor material, such as copper or aluminum. While these materials offer good conductivity, they have limitations in terms of mechanical strength, corrosion resistance, and environmental adaptability. For example, in high-temperature, high-humidity, or corrosive environments, single-material conductors are prone to oxidation and corrosion, leading to decreased conductivity and affecting the normal operation of the equipment. Furthermore, single-material conductors are also susceptible to breakage or deformation under complex mechanical stresses, such as tension and bending, reducing their lifespan and reliability.

[0004] Meanwhile, existing stranded intelligent conductor structures also have shortcomings in terms of intelligence and functional integration. With the development of IoT, big data, and artificial intelligence technologies, the requirements for the intelligence of conductor structures are becoming increasingly stringent. However, traditional conductor structures typically only possess basic conductivity functions and lack the ability to monitor and provide feedback on parameters such as current, voltage, and temperature in real time, thus failing to meet the demands of modern electrical systems for intelligence and adaptability.

[0005] Therefore, in order to improve the overall performance of twisted intelligent conductor structures, including mechanical strength, corrosion resistance, environmental adaptability and intelligence level, it is now urgent to make improvements to meet the growing electrical engineering needs and application scenarios.

[0006] Therefore, improvements are urgently needed to comprehensively enhance the fire resistance, mechanical properties, and electrical properties of the twisted intelligent conductor structure. Utility Model Content

[0015] The pitch ratio of the conductor body and one or more reinforcing layers during the stranding process is selected to be 12-18.

The connecting protrusions between two adjacent reinforcing units can be matched and extended into the connecting grooves so that the two reinforcing units can be connected.

[0017] In some feasible embodiments, the cross-sectional shape of the connecting groove is semi-circular, and the shape of the connecting flange matches the shape of the connecting groove.

[0032] In actual implementation, aramid fiber is selected as the material for tensile components.

[0033] In practical implementation, the structural design of communication unit B1 has yielded significant benefits. The tensile element B10, made of aramid fiber, not only effectively enhances the tensile strength of communication unit B1 but also reduces overall weight, improving the mechanical strength and durability of the conductor structure. The tubular support B12, made of metal, provides stable support and protection for the communication fiber B11, preventing external physical damage during use. It also enhances the overall structural stability of communication unit B1, improving its reliability in complex environments. Furthermore, the good thermal conductivity of the metal tubular support B12 aids in heat dissipation, extending the service life of the communication fiber B11. The communication fiber B11, wound around the outer periphery of the tensile element B10, achieves efficient signal transmission, offering advantages such as large transmission bandwidth, low signal attenuation, and strong anti-electromagnetic interference capabilities, meeting the demands of modern electrical systems for high-speed, stable communication. This design organically combines the tensile element B10, the communication fiber B11, and the tubular support B12, ensuring both the mechanical performance of communication unit B1 and efficient signal transmission, thus improving the overall performance and application range of the twisted intelligent conductor structure.

[0038] In actual implementation, the conductor single wire A10 is made of T1 copper.

[0039] In actual implementation, using T1 copper as the conductor monofilament material can significantly improve the conductor's conductivity, mechanical strength, and durability, while reducing production costs and maintenance difficulty, demonstrating significant technical advantages and practical application value.

[0040] In actual implementation, the reinforcing unit A3 is made of the same material as the conductor monofilament A10. This can effectively improve the conductivity of the conductor structure and prevent electrochemical reactions between the reinforcing layer and the conductor body.

[0048] In this embodiment, multiple reinforcing units A3 are arranged in a spiral pattern around the axis of the conductor body A1 and on the outer periphery of the conductor body A1.

[0049] In actual implementation, one or more interlocking reinforcing layers are set around the conductor body, which can effectively improve the structural stability of the conductor body and solve the overturning problem inherent in conventional conductor structures.

[0050] Furthermore, by setting one or more interlocking reinforcing layers around the conductor body, the conductor structure provided in this application does not involve any type of compression during stranding, thus preventing conductor hardening and increased conductor resistance, resulting in superior conductivity under the same cross-sectional conditions.
