Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a special-shaped tin-plated conductor structure for ship cables. Background Technology

[0002] In naval operations, cables are core components ensuring smooth power transmission and signal communication. Their performance directly affects the stable operation of various ship systems and overall safety. The working environment of ships is extremely unique and complex, placing stringent requirements on cable core structures. In terms of conductivity, ships carry numerous high-power devices, such as propulsion systems, weapon systems, and radar systems. When these devices operate simultaneously, cables need to transmit enormous currents. Existing cable core structures are often relatively simple, mostly using simply arranged round copper wires. When transmitting large currents, the current distribution is uneven, which can easily lead to localized overheating. This not only increases energy loss and reduces transmission efficiency but may also cause the cable insulation layer to age and be damaged due to overheating, resulting in short circuits and other faults, seriously affecting the normal operation of the ship. Furthermore, traditional cable core materials and structures are susceptible to corrosion in such harsh environments, reducing the conductivity of the conductor. As corrosion intensifies, it may even lead to core breakage, causing the cable to fail completely. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a special-shaped tin-plated conductor structure for ship cables, characterized in that it includes: a first core, a second core, a third core, and a fourth core, wherein the first core is a round copper wire, the second core consists of 6 round copper wires wrapped around the outside of the first core, the third core consists of 12 round copper wires wrapped around the outside of the second core, and the fourth core consists of trapezoidal copper wires twisted together and disposed on the outside of the third core.

[0004] Preferably, the first, second, third, and fourth wire cores are all tin-plated and have a tin layer on their outer side.

[0005] Preferably, a shielding layer is provided on the outside of the fourth wire core.

[0006] Preferably, the outer side of the shielding layer is provided with a metal braided wrapping layer.

[0007] Preferably, a wound armor layer is provided on the outer side of the winding layer.

[0008] Preferably, an outer protective layer is provided on the outside of the wound armor layer.

[0009] Beneficial effects

[0010] This utility model provides a special-shaped tin-plated conductor structure for ship cables, which has the following advantages: This solution adopts a layered wrapping design. The first core is a round copper wire, which serves as the conductive core and provides a basic current transmission channel. The second core consists of 6 round copper wires wrapped around the outside of the first core, and the third core consists of 12 round copper wires wrapped around the outside of the second core. This multi-layered wrapping structure significantly increases the effective cross-sectional area of ​​the conductor, allowing the current to be distributed more evenly in all parts of the core, effectively reducing the conductor resistance, reducing energy loss when current passes through, and improving the transmission efficiency of the cable. It can more stably supply power to various equipment on the ship and meet the power demand of high-power equipment on the ship. All cores are tin-plated, forming a dense tin layer on the outside of the conductor. Tin has good chemical stability. In the high humidity and high salt spray environment of the ocean, the tin layer can effectively isolate the conductor from contact with external corrosive substances, preventing the copper core from being oxidized and corroded. The four cores are arranged with trapezoidal copper wires stranded outside the third core. The special shape of the trapezoidal copper wires makes it possible to... The stranded cores can be more tightly bonded, resulting in a structure with high mechanical strength and flexibility. When subjected to external forces, such as ship swaying or equipment vibration, this structure can evenly distribute stress, preventing localized stress concentration that could damage the cores. Furthermore, the excellent flexibility makes cable laying easier when bending, reducing internal stress caused by bending and lowering the risk of core fatigue damage. This ensures long-term stable operation of the cable under the complex mechanical conditions of a ship. It also solves the problem that existing cable core structures are often relatively simple, using a simple arrangement of round copper wires. When transmitting large currents, uneven current distribution can easily lead to localized overheating, increasing energy loss, reducing transmission efficiency, and potentially causing insulation aging and damage, leading to short circuits and other faults that severely affect the normal operation of the ship. Moreover, traditional cable core materials and structures are susceptible to corrosion in such harsh environments, reducing conductor conductivity. With increasing corrosion, core breakage can even occur, causing complete cable failure. Attached Figure Description

[0014] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Example: Please refer to Figure 1-2 The first conductor 1, serving as the central load-bearing core, is composed of a solid, round, tinned copper wire. The second conductor 2 consists of six round, tinned copper wires tightly twisted concentrically and wrapped around the outside of the first conductor 1, forming the first stranded layer. The third conductor 3 consists of twelve round, tinned copper wires tightly twisted concentrically and wrapped around the outside of the second conductor 2, forming the second stranded layer, further increasing the conductor's cross-sectional area. The fourth conductor 4, as the outermost conductor, consists of multiple trapezoidal-section tinned copper wires twisted together and placed outside the third conductor 3. The trapezoidal wires achieve a tighter fit during twisting, effectively reducing gaps and unevenness on the conductor's outer surface, resulting in extremely high overall conductor roundness. This significantly improves the uniformity and performance of the subsequent shielding layer and sheath. The shielding layer 5 tightly covers the outside of the fourth conductor 4. This shielding layer is typically made of copper strip and is mainly used to resist external electromagnetic interference. To prevent EMI and internal signal leakage, the winding layer 6 is woven on the outside of the shielding layer 5. This winding layer is made of multiple fine tinned copper wires or soft copper wires crisscrossed to form a flexible mesh, which greatly enhances the cable's flexibility and resistance to repeated bending fatigue. The coiled armor layer 7 is located on the outside of the winding layer 6. In this embodiment, tinned copper strip is used for gap winding to form an armor layer. This layer structure is the main mechanical protection layer, which can effectively resist mechanical damage such as squeezing, impact, and biting, providing a solid guarantee for the installation and use of the cable in the complex compartments of ships. The outer protective layer 8 is extruded on the outermost side of the coiled armor layer 7. This protective layer is made of high-performance flame-retardant, oil-resistant, corrosion-resistant, and weather-resistant elastomer materials such as low-smoke halogen-free flame-retardant polyolefin or chlorosulfonated polyethylene. It is a barrier between the cable and the external environment, ensuring that the cable can work stably for a long time in various harsh environments.
