[0002] Cables are electrical wires and cables made of one or more insulated conductors and an outer insulating protective layer. They are used to transmit electrical energy, signals, and realize electromagnetic energy conversion. The main function of cables is to transmit electrical energy. In power systems, from power plants to substations and then to various power-consuming terminals such as factories, enterprises, and residential buildings, electrical energy needs to be transmitted through cables to enable various electrical devices to operate normally. In the field of communications, cables are used to transmit various signals, such as telephone signals, network signals, and cable television signals. For example, fiber optic cables can transmit large amounts of data signals at high speeds, enabling long-distance communication and information exchange.

[0003] Marine cables are electrical wires and cables used in special environments such as ships and offshore platforms. The marine environment contains a large amount of salt spray, moisture and various corrosive substances. In order to resist the erosion of these substances and ensure the service life and reliability of the cables, the materials of marine cables need to have excellent corrosion resistance. Marine cables need to be in contact with water for a long time. In order to effectively prevent water intrusion and avoid problems such as deterioration of electrical performance and short circuits, they need to have good water resistance. Therefore, it is necessary to propose a corrosion-resistant marine cable. Utility Model Content

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0021] like Figures 1 to 3 As shown, this utility model proposes a corrosion-resistant marine cable, comprising a cable body 1, which includes multiple conductor bodies 2 concentrically and uniformly distributed. Each conductor body 2 is formed by stranding multiple fine wires and possesses conductivity and mechanical strength, improving the flexibility and bendability of the cable body 1. Each conductor body 2 has a natural-colored insulation layer 3 on its exterior. The outer ring of the conductor body 2 is fixedly connected to the inner ring of the natural-colored insulation layer 3. The natural-colored insulation layer 3 is made of ethylene propylene rubber, a synthetic rubber with excellent water resistance, weather resistance, electrical insulation properties, good flexibility, and low viscosity. It has excellent thermal performance, effectively isolating the conductor body 2 to prevent current leakage and short circuits, ensuring the safety and stability of power transmission. It can withstand various voltage levels in marine environments and maintain stable performance in humid or even underwater environments for a long time. It prevents moisture from entering the conductor body 2 and causing a decline in electrical performance. It has good resistance to salt spray, acid and alkali and other chemicals in marine environments and is not easily corroded, thus extending the service life of the cable body 1. It has good elasticity and flexibility, and can adapt to the vibration and swaying of the ship during navigation as well as the bending and stretching of the cable body 1. It is not easy to crack or break, ensuring the mechanical performance of the cable body 1.

[0022] Each natural-colored insulation layer 3 has a color-coded insulation strip 4 on one side. Each color-coded insulation strip 4 has a different color and is made of the same material as the natural-colored insulation layer 3. This allows the conductor body 2 with a specific function or purpose to be distinguished from other conductor bodies 2. In the complex electrical systems of ships, this facilitates quick identification and retrieval by installation and maintenance personnel, reduces the probability of operational errors, and improves work efficiency. Each natural-colored insulation layer 3 has a semi-conductive conductor shielding layer 5 on its exterior. The semi-conductive conductor shielding layer 5 is made of semi-conductive materials, such as ethylene propylene rubber and cross-linked polyethylene, modified with conductive fillers such as carbon black. This gives the cable body 1 functions such as uniform electric field, elimination of corona, protection of insulation layer, and grounding protection. Each semi-conductive conductor shielding layer 5 has a semi-conductive insulating shielding layer 6 on its exterior. The semi-conductive insulating shielding layer 6 is made of polymer materials containing conductive substances such as carbon black. For example, adding an appropriate amount of conductive filler to insulating materials such as ethylene propylene rubber and cross-linked polyethylene forms a semi-conductive composite material, which can uniform electric field, control partial discharge, shield electromagnetic interference, and also provide certain safety protection.

[0023] Each semiconductive insulating shield layer 6 is surrounded by a common filling layer 7. This filling layer 7 not only provides support but also prevents friction and movement between the conductor bodies 2. It also offers some waterproofing and heat insulation. Outside the filling layer 7 is an insulating layer 8, made of materials such as mica tape and ceramicized silicone rubber. This insulating layer 8 forms a heat insulation layer in special circumstances such as fires, preventing heat transfer, protecting the internal structure of the cable body 1, and improving its fire and explosion resistance. Outside the insulating layer 8 is an inner sheath 9, made of materials such as polyvinyl chloride and polyethylene. This inner sheath 9 has good water resistance and chemical corrosion resistance, protecting the color stripes. The color-coded insulation 4 and the semi-conductive conductor shielding layer 5 are protected from damage by external factors, while also preventing the intrusion of moisture and corrosive substances. An armor layer 10 is provided on the outside of the inner sheath 9. The armor layer 10 is made of materials such as steel strip and steel wire, and is wrapped around the outer side of the inner sheath 9 in a spiral or longitudinal manner. The steel strip armor can withstand a certain amount of pressure and tension, preventing mechanical damage to the cable body 1, and also plays a certain role in explosion protection. An outer sheath 11 is provided on the outside of the armor layer 10. The outer sheath 11 is made of materials such as chloroprene rubber and chlorinated polyethylene, which has excellent resistance to seawater corrosion, oil, and ozone, and can effectively protect the internal structure of the cable from the erosion of the marine environment. It also has a certain degree of flame retardancy, which can improve the explosion protection performance of the cable.

[0024] In this embodiment, when using this device, by setting the natural color insulation layer 3, the cable body 1 has excellent water resistance, weather resistance, electrical insulation performance, as well as good flexibility and low temperature performance. By setting the color-coded insulation 4, cables with specific functions or uses can be distinguished from other cables. In the complex electrical system of a ship, this facilitates quick identification and retrieval by installation and maintenance personnel, reduces the probability of operational errors, and improves work efficiency. By setting the semi-conductive conductor shielding layer 5 and the semi-conductive insulating shielding layer 6, the natural color insulation layer 3 and the color-coded insulation 4 are easily protected. By setting the isolation layer 8, the internal structure of the cable body 1 is protected, improving the fire resistance and explosion-proof performance of the cable body 1. By setting the inner sheath 9, the natural color insulation layer 3 and the color-coded insulation 4 are protected from damage by external factors, while preventing the intrusion of moisture and corrosive substances. By setting the armor layer 10, the mechanical strength and explosion-proof performance of the cable body 1 can be enhanced. By setting the outer sheath 11, the internal structure of the cable can be effectively protected from the corrosion of the marine environment, and it also has a certain flame retardancy, which can improve the explosion-proof performance of the cable.
