Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a lightweight control cable for ships with high-temperature insulation. Background Technology

[0002] Control cables used in ship generator rooms require small outer diameter and lightweight design. Operating in the high-temperature and high-humidity environment of the generator room, these cables must maintain good electrical and mechanical properties, and possess excellent shielding performance, flame retardancy, water resistance, oil resistance, corrosion resistance, and aging resistance.

[0003] Currently, the insulation and sheathing materials for shipboard control cables are generally low-smoke, halogen-free, radiation-crosslinked polyolefins, which are insufficient to meet the above requirements. Furthermore, existing shipboard control cables are large in diameter and heavy, making them unsuitable for laying in confined and complex environments such as generator rooms, resulting in excessive physical exertion for construction workers.

PEKK also has low moisture absorption, which can maintain stable performance in humid environments and reduce dimensional changes and performance degradation caused by moisture absorption. In addition, it has oil resistance, chemical corrosion resistance, radiation resistance, and aging resistance. It also has unique self-lubricating and low friction properties, which meet the requirements for reliable use in harsh and complex environments and have a good service life.

[0017] Furthermore: the packing tape is formed by wrapping a polyimide film tape around the packing tape;

[0018] The polyimide film tape has a thickness of 0.03 mm and an overlap rate of ≥30%.

[0019] The beneficial effect of this step is that the tightness of the wrapping can be controlled by the overlap rate.

[0020] Furthermore: the metal shielding layer comprises an aluminum-plastic composite strip and a first metal braided tube;

[0021] The aluminum-plastic composite strip is longitudinally wrapped around the outer side of the wrapping strip partition, with the aluminum foil side of the aluminum-plastic composite strip facing outwards, and the thickness of the aluminum-plastic composite strip is 0.04mm;

[0022] The first metal braided tube is sleeved outside the aluminum-plastic composite strip, and the braiding wire of the first metal braided tube is made of tin-plated copper-clad aluminum-magnesium alloy, with a wire diameter of 0.12mm.

[0023] The beneficial effects of this step are: good anti-interference effect.

[0024] Furthermore, the material of the wrapping layer is a high flame-retardant glass fiber cloth tape.

[0025] Furthermore: the metal armor layer is a second metal braided tube, which is sleeved outside the wrapping layer;

[0026] The braiding wire of the second metal braided tube is made of tin-plated copper, and the diameter of the tin-plated copper wire is 0.1~0.15mm.

[0027] The benefits of this step include: not only achieving good protective performance, but also improving the mechanical strength, tensile strength, and bending performance of the cable.

[0028] The beneficial effects of this utility model are:

[0029] The cable of this application has good high temperature resistance and can be used for a long time at 250℃; it is resistant to high temperature and moisture; it has good insulation performance; it has a small outer diameter and light weight; it has good shielding ability for electromagnetic interference signals; and it also has good flame retardant performance, high mechanical strength, oil resistance, corrosion resistance, aging resistance, and wear resistance.

[0047] The insulating layer 2 and the sheath 8 are made of PEKK.

[0048] In this invention, the insulation layer 2 and the sheath 8 use PEKK (polyether ketone ketone), which can withstand temperatures up to 250°C. PEKK also has low moisture absorption, which can maintain stable performance in humid environments and reduce dimensional changes and performance degradation caused by moisture absorption. In addition, it has oil resistance, chemical corrosion resistance, radiation resistance, and aging resistance. It also has unique self-lubricating and low friction properties, which meet the requirements for reliable use in harsh and complex environments and have a good service life.

[0049] Based on the above technical solution, the conductor is tin-plated soft round copper.

[0050] It has good electrical conductivity and mechanical strength.

[0051] Based on the above technical solution, the thickness of the insulating layer 2 is 0.3~0.35mm.

[0052] While achieving the insulation function, the thickness of the insulation layer 2 is controlled to achieve the goal of lightweighting.

[0054] The thickness of the polyimide film strip is 0.03 mm, and the overlap rate of the polyimide film strip is ≥30%, which means that the overlap width of the polyimide film strip is ≥30% of the width of the polyimide film strip.

[0056] Based on the above technical solution, the metal shielding layer 7 includes an aluminum-plastic composite strip and a first metal braided tube;

[0057] The aluminum-plastic composite strip is longitudinally wrapped around the outer side of the wrapping strip partition 3, with the aluminum foil side of the aluminum-plastic composite strip facing outwards, and the thickness of the aluminum-plastic composite strip is 0.04mm;

[0062] It not only provides excellent protection but also improves the cable's mechanical strength, tensile strength, and bending performance.

[0064] 1) Good high temperature resistance

[0065] The cable insulation layer 2 and sheath 8 are made of PEKK material, with a temperature resistance rating of up to 250℃.

[0066] 2) Small outer diameter and light weight

[0067] The cable adopts a lightweight design in several aspects: 1. The insulation layer 2 adopts a thin design; 2. The metal shielding layer 4 adopts low-density aluminum-plastic composite tape and tin-plated copper-clad aluminum-magnesium alloy wire; 3. The metal armor layer 7 adopts a lightweight design; 4. The density of the insulation layer 2 and the sheath 8 is also lower than that of conventional irradiated cross-linked polyolefin materials; while meeting the high-density wiring requirements in the limited space of ships, it also reduces weight.

[0068] 3) Strong anti-interference ability

[0069] The cable's metal shielding layer 4 and outer metal armor layer 7 provide excellent electromagnetic shielding capabilities, which can greatly reduce signal interference and ensure reliable and stable signal transmission.

[0070] 4) Good flame retardant properties

[0071] The PEKK material used in insulation layer 2 and sheath 8 has an oxygen index much higher than that of ordinary flame-retardant materials, and has good flame-retardant properties; the glass fiber filler 5 and the wrapping layer 6 of high flame-retardant tape also have a strong flame-retardant effect; the cable can meet the Class A flame-retardant requirements for bundled cables.

[0072] 5) Good mechanical and physical properties

[0073] The insulation layer 2 and the sheath 8 have high mechanical strength and strong resistance to scratches and fatigue. The metal shielding layer 4 and the metal armor layer 7 can also protect the cable core, reduce the damage to the cable core caused by external mechanical forces, and enhance the mechanical strength, tensile strength and bending performance of the cable.

[0074] 6) Environmental resistance

[0075] PEKK's sheath 8 has a low moisture absorption rate, which enables it to maintain stable performance in humid environments, reducing dimensional changes and performance degradation caused by moisture absorption. In addition, it is also resistant to oil, chemical corrosion, radiation, and aging. Furthermore, it has unique self-lubricating and low-friction properties, meeting the requirements for reliable use in harsh and complex environments and having a good service life.
