Description

Technical Field

[0001] This utility model relates to the field of power supply cables for steam turbine units, specifically to a weather-resistant cable for steam turbine units on ocean-going ships. Background Technology

[0002] A cable is an electrical energy or signal transmission device, typically composed of several or groups of conductors, and characterized by internal current transmission and external insulation. Cables come in many types, and can be categorized based on their application, structure, and materials. Power cables are primarily used for transmitting and distributing electricity, including high-voltage cables, medium-voltage cables, and low-voltage cables. Ocean-going ship turbines, as an important component of ship propulsion systems, possess advantages such as high power, small size, light weight, rapid start-up, good acceleration, and good maneuverability. Ocean-going ship turbines require specialized cables for power supply during operation.

[0003] Existing cables for steam turbine units on ocean-going vessels have poor weather resistance, making them unsuitable for use at high and low temperatures. The cables are also easily damaged when dragged or crushed, which does not improve the service life of the cables on ocean-going vessels. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a weather-resistant cable for ocean-going ship turbine units. The cable for ocean-going ship turbine units has outstanding weather resistance, can be used at high and low temperatures, and is tensile-resistant, making the overall cable less prone to damage during dragging and crushing, thus improving the service life of the cable on ocean-going ships.

[0005] The technical solution adopted by this utility model to solve its technical problem is a weather-resistant cable for ocean-going ship turbine units, including an insulating filling layer, a PU outer sheath, a silicone rubber inner sheath, a polypropylene braided rope and a branch core bundle. An elastic filling layer is provided between the PU outer sheath and the silicone rubber inner sheath. An outer heat insulation layer and an inner heat insulation layer are respectively provided between the elastic filling layer and the PU outer sheath and the silicone rubber inner sheath. Both the outer heat insulation layer and the inner heat insulation layer are made of silicon carbide fiber braiding.

[0006] The inner silicone rubber sheath has a polypropylene braided rope at its core, and the outer side of the polypropylene braided rope is wrapped with a toughening layer. The outer side of the toughening layer is provided with branch core bundles at equal intervals. The outer surface of the branch core bundles is provided with a wrapping layer, and the outer surface of the wrapping layer is provided with an aramid filament braided layer. The outer surface of the PU outer sheath is coated with an oil-resistant layer, specifically a polyacrylate coating.

[0007] By adopting the above technical solutions, the steam turbine cables for ocean-going vessels exhibit outstanding weather resistance, enabling them to be used at both high and low temperatures. Furthermore, they are tensile-resistant, making the cables less susceptible to damage during dragging and crushing, thus extending their service life on ocean-going vessels.

[0008] Specifically, the elastic filler layer is made of polyurethane elastic material.

[0009] By adopting the above technical solution, the overall cable elasticity is increased, making it easier to bend during wiring and less likely to damage the internal branch core bundles.

[0010] Specifically, the insulating filler layer is made of PE material.

[0011] By adopting the above technical solution, the insulation filling layer is specifically made of PE material, which facilitates the wrapping and limiting of the branch core bundle, resulting in outstanding insulation effect and improved leakage prevention.

[0012] Specifically, the toughening layer is made of silicone material.

[0013] Specifically, the wrapping layer is made of flame-retardant polyvinyl chloride material.

[0014] The beneficial effects of this utility model are:

[0015] (1) The weather-resistant cable for ocean-going ship turbine units described in this utility model has an outer heat insulation layer and an inner heat insulation layer made of silicon carbide fiber braiding. It has good thermal stability and high temperature resistance. When used on ocean-going ship turbine units, it will not be damaged by high temperature. The outer sheath of PU is resistant to low temperature and has good tear resistance and elasticity. The elastic filling layer is made of polyurethane elastic material, which increases the elasticity of the overall cable. It is easy to bend during wiring and is not easy to damage the internal branch core bundle.

[0016] (2) The weather-resistant cable for ocean-going ship turbine units described in this utility model utilizes the outer wrapping layer of the branch core bundle, which is made of flame-retardant polyvinyl chloride material. It is resistant to high temperature, has a significant flame-retardant effect, is puncture-proof, and is not easily damaged. The aramid fiber braided layer improves the tensile strength of the branch core bundle, so the branch core bundle will not be damaged when the cable is pulled. Furthermore, the polypropylene braided rope has high mechanical strength and tensile strength, making the overall cable less prone to damage when dragged or crushed, thus improving the service life of the cable on ocean-going ships.
