Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically a reinforced oil-resistant and hydrolysis-resistant marine engineering instrument control cable. Background Technology

[0002] Marine engineering instrument control cables are special cables designed specifically for marine environments. They are primarily used to transmit instrument signals, control commands, and power, ensuring the stable operation of various instruments and control systems in offshore platforms, subsea oil and gas fields, ships, and deep-sea exploration equipment. Their core function is to achieve precise signal transmission and equipment control in harsh marine environments, making them a critical infrastructure for the automation and intelligentization of marine engineering.

[0003] In existing technologies, as the development of shallow-sea oil fields matures, offshore oil extraction is expanding into deep seas, which places higher demands on cable performance. The high-pressure and low-temperature environments of deep seas require cables to possess stronger mechanical strength and insulation properties. Seawater, salt spray, and microbial corrosion necessitate the use of more durable materials for cables. In particular, complex environments such as extraction platforms place higher demands on various aspects of cable performance, especially in terms of resistance to liquids (including oil and hydrolysis). Traditional platform cables, due to performance limitations, cannot meet these requirements. Therefore, we propose a reinforced oil- and hydrolysis-resistant marine engineering instrument control cable. Utility Model Content

[0004] The purpose of this invention is to provide a reinforced, oil- and hydrolysis-resistant marine engineering instrument control cable to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforced oil- and hydrolysis-resistant marine engineering instrument control cable, comprising two sets of insulation barrier layers, wherein multiple sets of cable cores are arranged inside the insulation barrier layers, double insulation is arranged outside the insulation barrier layers, a filling layer is arranged outside the double insulation layers, and an inner sheath is arranged outside the filling layer.

[0006] Preferably, the inner protective layer is provided with a wrapping layer on the outside, and the wrapping layer is provided with an outer protective sleeve on the outside.

[0007] Preferably, the outer sheath is provided with a fire-resistant layer, and the fire-resistant layer is provided with a woven armor layer.

[0008] Preferably, four sets of reinforcing cores are provided inside the filling layer and along the length of the filling layer.

[0009] Preferably, the cable core is a circular tin-plated copper conductor, and the double insulation includes an insulation layer one and an insulation layer two sleeved outside the insulation layer one. The insulation layer one is made of ethylene propylene rubber, and the insulation layer two is made of cross-linked polyethylene.

[0010] Preferably, the outer sheath is made of polyvinyl chloride, and the braided armor layer is made of tin-plated copper wire braided armor. The tin-plated copper wire braided armor not only provides mechanical protection but also serves as overall shielding, increasing the cable's shielding effect.

[0011] Preferably, the reinforcing core is made of stainless steel wire, and the insulating barrier layer is made of polypropylene.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model combines an outer sheath, a braided armor layer, a wrapping layer, a reinforcing core, an insulation layer two, an insulation layer one, a filling layer, an insulation barrier layer, a cable core, and an inner sheath. Through complementary material properties and hierarchical structural protection, it systematically solves the shortcomings of traditional marine cables in terms of oil and hydrolysis resistance, mechanical strength, and insulation reliability. It is especially suitable for extreme environments of deep sea high pressure, high corrosion, and high mechanical stress, providing long-term protection for the stable transmission of control signals for marine engineering instruments.

[0014] (2) The present invention uses a reinforced core made of stainless steel wire, which has high strength characteristics that can effectively resist the axial tension of the cable in marine engineering (such as the tensile force during laying and towing), avoid the cable from breaking or deforming due to excessive force, and ensure that the cable maintains physical integrity in the deep-sea high-pressure environment. When laying deep-sea cables, they need to withstand their own weight and water flow impact. The high tensile strength of stainless steel wire can prevent the cable from being pulled apart and ensure the continuity of signal transmission. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1

[0020] Please see Figures 1-2 This utility model provides a technical solution: a reinforced oil- and hydrolysis-resistant marine engineering instrument control cable, comprising two sets of insulation barrier layers 108, with multiple cable cores 109 arranged inside the insulation barrier layer 108, and a double-layer insulation on the outside of the insulation barrier layer 108. While ensuring transmission performance, the double-layer insulation provides strong environmental resistance for each cable core 109, including flame retardancy, oil resistance, and hydrolysis resistance. A filler layer 107 is arranged outside the double-layer insulation, and an inner sheath 110 is arranged outside the filler layer 107. The inner sheath 110 is resistant to liquid radiation. Irradiated crosslinked elastomers are outer insulating materials designed for special environments (such as marine engineering, chemical industry, oil pollution, and other highly corrosive or liquid-eroded scenarios). Using rubber-based elastomers or thermoplastic elastomers as the base material, they are treated with high-energy rays to form a three-dimensional network crosslinked structure between the elastomer molecular chains. This significantly improves the material's heat resistance, liquid resistance, hydrolysis resistance, mechanical strength, and chemical stability, greatly enhancing the product's liquid resistance (its ability to resist liquid erosion, penetration, dissolution, or chemical reactions), ensuring the product's use in complex marine environments.

[0021] The inner protective layer 110 is provided with a wrapping layer 103 on the outside, and the wrapping layer 103 is provided with an outer sheath 101 on the outside;

[0022] The outer sheath 101 is provided with a fire-resistant layer 100. In some cables exposed in seawater and connected to the controller, it can provide fire protection for the cable in the event of an external fire. The fire-resistant layer 100 is composed of multiple layers of mica tape spirally wrapped to form a continuous and dense protective layer. The mica tape still maintains a dielectric strength of ≥20kV / mm at a high temperature of 800℃, effectively isolating flames and improving the fire resistance of the cable during use. The fire-resistant layer 100 is provided with a braided armor layer 102.

[0023] A reinforcing core 104 is provided inside the filling layer 107 and along the length of the filling layer 107, and four sets of reinforcing cores 104 are provided. The filling layer 107 is a polypropylene rope, which has high tensile strength and wear resistance, and improves the service life of the cable.

[0024] Example 2

[0025] Please refer to Example 1. Figures 1-2The cable core 109 is a round tin-plated copper conductor. The double insulation includes insulation layer 106 and insulation layer 105 sleeved outside insulation layer 106. Insulation layer 106 is made of ethylene propylene rubber. In terms of electrical insulation performance, ethylene propylene rubber has high insulation resistance and corona resistance. In terms of mechanical performance, it has high elasticity and flexibility, as well as weather resistance and chemical resistance. Insulation layer 105 is made of cross-linked polyethylene. In terms of electrical insulation performance, cross-linked polyethylene has high breakdown field strength and low water absorption. In terms of mechanical performance, it has low water absorption.

[0026] The outer sheath 101 is made of polyvinyl chloride (PVC), which can effectively resist friction, extrusion and minor impact, protecting the internal structure. The braided armor layer 102 is made of tin-plated copper wire braided armor. The tin-plated copper wire is woven into a mesh structure, which can withstand axial tension and radial extrusion, protecting the internal structure from mechanical damage during use.

[0027] The reinforcing core 104 is made of stainless steel wire. Stainless steel wire will not rust and can increase the tensile strength of the cable during use, making it less prone to breakage. The insulation barrier layer 108 is made of polypropylene. Polypropylene can block the path of moisture penetration and maintain insulation performance. The wrapping layer 103 is formed by wrapping fiber tape.

[0028] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
