Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a moisture-proof and corrosion-resistant cable for a port. Background Art

[0002] With the rapid development of global maritime trade, ports, as important shipping nodes, carry a large amount of import and export cargo transportation and circulation. The port's power system is a key infrastructure supporting port operations. Its stability and security directly affect the port's operational efficiency and safe production. However, the special environmental conditions of the port, such as high humidity, high salinity and sea breeze, pose severe challenges to the cables in the power system.

[0003] Traditional moisture-proof and corrosion-proof measures mainly rely on coating the outer layer of the cable with anti-corrosion materials, such as polyethylene, polyvinyl chloride, etc. However, these materials will gradually age in long-term use, and the coating may crack and peel off, resulting in a decrease in the protective effect. In addition, a single protective layer cannot fully cope with the multiple challenges of the port environment. Therefore, a port moisture-proof and corrosion-proof cable is needed to solve the existing deficiencies. Utility Model Content

[0004] Technical issues solved

[0005] The utility model aims to make up for the deficiencies of the prior art and provides a port moisture-proof and corrosion-resistant cable.

[0006] Technical Solution

[0007] To achieve the above purpose, the utility model provides the following technical solution: a port moisture-proof and corrosion-resistant cable, comprising:

[0008] The conductor layer, made of high-purity copper or aluminum, is used for efficient power transmission;

[0009] The inner insulation layer, wrapped around the conductor layer, is made of cross-linked polyethylene (XLPE) or ethylene-propylene rubber (EPR) and is used to provide primary insulation protection;

[0010] The moisture barrier is wrapped around the inner insulating layer and is made of a fluorinated polymer material with a nano-porous structure to prevent moisture penetration;

[0011] Metal shielding layer, wrapped outside the moisture-proof layer, made of aluminum-plastic composite tape or copper tape, used for electromagnetic shielding and preventing mechanical damage;

[0012] The outer insulation layer, wrapped outside the metal shielding layer, is made of corrosion-resistant polyurethane material and is used to provide secondary insulation protection and corrosion resistance.

[0013] As mentioned above, the fluorinated polymer material of the moisture-proof layer is fluorosilicone rubber or polytetrafluoroethylene (PTFE).

[0014] As mentioned above, the corrosion-resistant polyurethane material of the outer insulating layer is added with an anti-ultraviolet agent to improve the anti-aging performance of the cable when used outdoors.

[0015] As mentioned above, the metal shielding layer also includes a layer of galvanized steel tape to further enhance the mechanical strength and corrosion resistance of the cable.

[0016] As mentioned above, the conductor layer adopts a multi-strand twisted structure to improve the flexibility and tensile strength of the cable.

[0017] Beneficial effects:

[0018] Compared with the prior art, this port moisture-proof and corrosion-resistant cable has the following beneficial effects:

[0019] 1. The cable of the utility model adds a moisture-proof layer outside the inner insulation layer and adopts a fluorinated polymer material with a nano-microporous structure (such as fluorosilicone rubber or polytetrafluoroethylene PTFE) to effectively prevent moisture penetration and prevent the humid environment from invading the inside of the cable. This design greatly improves the moisture-proof performance of the cable in the high-humidity port environment and ensures the insulation stability and reliability of the cable in long-term use.

[0020] 2. The outer insulation layer of the utility model cable adopts corrosion-resistant polyurethane material and adds anti-ultraviolet agent to improve the anti-aging performance of the cable in outdoor exposure environment. At the same time, the metal shielding layer adopts aluminum-plastic composite belt or copper belt, and adds galvanized steel belt layer to provide multiple anti-corrosion protection. This multi-layer protection design effectively resists the corrosion of salt spray in the port environment, prolongs the service life of the cable, and reduces the maintenance cost and frequency.

[0021] 3. The utility model adopts a conductor layer of a multi-strand twisted structure, combined with the mechanical protection of a galvanized steel strip, so that the cable has high tensile strength and compressive strength, and can withstand mechanical extrusion, stretching and wear in the port environment. In addition, the multi-strand twisted structure improves the flexibility of the cable, making it more convenient during laying and use, adapting to complex laying paths, reducing installation difficulty and time, and improving work efficiency.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1-4 As shown, the utility model provides a technical solution: a port moisture-proof and corrosion-resistant cable. The conductor layer 1 is the core component of the cable, which directly affects the electrical and mechanical properties of the cable. In the utility model, the conductor layer 1 is made of high-purity copper or aluminum. The specific material can be adjusted according to the actual application requirements. In order to improve the flexibility and tensile strength of the cable, the conductor layer 1 adopts a multi-strand twisted structure. The multi-strand twisted structure can significantly improve the flexibility of the conductor by twisting multiple thin copper wires or aluminum wires together, making it easier to bend and install during the laying process. In addition, the multi-strand twisted structure can also enhance the tensile strength of the conductor and reduce the risk of breakage during use.

[0031] Embodiment 2:

[0032] The main function of the inner insulating layer 2 is to provide electrical insulation protection for the conductor, prevent current leakage, and ensure the safety of the cable under different working conditions. For this reason, the utility model selects cross-linked polyethylene (XLPE) or ethylene-propylene rubber (EPR) as the inner insulating material.

[0033] Cross-linked polyethylene (XLPE): XLPE is a polymer material that forms cross-links between polyethylene molecular chains by chemical or physical methods. XLPE has high insulation resistance and good thermal stability, and can maintain stable insulation performance under high temperature environments. In addition, XLPE also has excellent chemical corrosion resistance and can resist the erosion of various chemical substances, making it suitable for use in harsh environments.

[0034] Ethylene Propylene Rubber (EPR): EPR is a synthetic rubber with excellent elasticity and weather resistance, and can maintain good insulation properties even in low temperature environments. In addition, EPR has good ozone resistance and aging resistance, and can maintain stable physical and electrical properties in long-term use.

[0035] Embodiment 3:

[0036] The moisture-proof layer 3 is an important innovation in the present invention. By providing a fluorinated polymer material with a nano-microporous structure, it can effectively prevent water penetration and protect the internal structure of the cable from moisture.

[0037] Fluorinated polymer materials: Fluorosilicone rubber and polytetrafluoroethylene (PTFE) are commonly used fluorinated polymer materials. These materials have extremely low water permeability and excellent chemical corrosion resistance. Fluorosilicone rubber maintains stable physical properties over a wide temperature range and can perform well in both high and low temperature environments. PTFE has excellent heat resistance and low friction coefficient and can be used for a long time in harsh environments.

[0038] The design of the nano-microporous structure enables the moisture-proof layer 3 to not only prevent moisture from entering, but also maintain a certain air permeability to prevent water vapor from accumulating inside the cable, thereby further improving the moisture-proof performance of the cable.

[0039] Embodiment 4:

[0040] The main function of the metal shielding layer 4 is to provide electromagnetic shielding and mechanical protection. In the utility model, the metal shielding layer 4 is made of aluminum-plastic composite tape or copper tape, and a layer of galvanized steel tape is added to enhance the mechanical strength of the cable.

[0041] Aluminum-plastic composite tape: Aluminum-plastic composite tape is made of aluminum foil and plastic film, which has good electromagnetic shielding effect and can effectively reduce the impact of external electromagnetic interference on cable signal transmission. Aluminum-plastic composite tape also has a certain mechanical strength and can provide basic mechanical protection.

[0042] Copper tape: Copper tape has excellent electrical conductivity and mechanical strength. As the metal shielding layer 4, it can provide higher electromagnetic shielding effect and stronger mechanical protection.

[0043] Embodiment 5:

[0044] The outer insulating layer 5 is the outermost layer of the cable, and its main function is to provide secondary insulation protection and anti-corrosion performance. The utility model selects corrosion-resistant polyurethane material as the outer insulating layer 5.

[0045] Corrosion-resistant polyurethane material: Polyurethane material has excellent wear and corrosion resistance and can be used for a long time in the marine environment without damage. In addition, polyurethane material also has good mechanical strength and flexibility, which can provide comprehensive protection for the cable.

[0046] In order to improve the anti-aging performance of cables when used outdoors, anti-ultraviolet agents can be added to polyurethane materials. These anti-ultraviolet agents can effectively prevent ultraviolet rays from damaging polyurethane materials and prevent the cables from aging and performance degradation due to long-term exposure to sunlight.

[0047] In summary, the utility model provides a port moisture-proof and corrosion-resistant cable with a multi-layer structure and excellent comprehensive protection performance. By selecting high-purity conductor materials, multi-layer insulation and shielding structures, and advanced production processes, the cable of the utility model can maintain stable performance for a long time in the harsh environment of the port, providing reliable protection for the port power and signal transmission system.
