TECHNICAL FIELD

[0001] The utility model relates to the technical field of intermediate frequency cable, specifically is a flexible degradable insulation intermediate frequency cable. BACKGROUND

[0002] In the aviation and large ship power system, the shipboard generator must meet the power demand by improving the power supply frequency due to the volume and weight restrictions. Therefore, the power supply system of the shipboard electrical equipment and the aircraft-related power supply system generally adopts 400Hz power supply facilities, which correspondingly requires that the matching cable must meet the high-standard technical performance of the 400Hz system. Especially in the case of needing to transmit signals and power at the same time and requiring the cable to have excellent shielding performance and good environmental adaptability, the existing solutions are often unsatisfactory.

[0003] In addition, high-frequency cables often face harsh natural environmental conditions such as chemical corrosion, temperature difference changes, and ozone during long-term operation, which can damage the insulation layer of the cable and shorten its service life. At the same time, due to the limitations of cable laying space and the inevitable dragging and bending operations during installation, the cable needs to have lightweight and high-strength characteristics to adapt to these challenges.

[0004] The technical team has redesigned a flexible degradable insulation intermediate frequency cable according to the requirements of existing materials, cable structure, and cable electrical performance. UTILITY MODEL CONTENT

[0007] The insulation layer and the insulation layer are made of degradable bio-based polyurethane or polyamide elastomer material.

[0008] Preferably, the power insulation wire core comprises a conductor and an insulation layer, the power insulation wire core is composed of a conductor wrapped with an insulation layer, and the power insulation wire core is provided with at least three.

[0009] Preferably, the control insulated wire core comprises a conductor, an insulation layer, a first filling layer, a wrapping layer, and a total shielding layer, the conductor is coated with the insulation layer, at least four conductors are twisted together, the conductor and the insulation layer are provided with the wrapping layer, the first filling layer is filled between the wrapping layer and the insulation layer, and the wrapping layer is sleeved with the total shielding layer.

[0010] Preferably, the total shielding layer adopts a copper wire braiding structure, and the braiding density is not less than 90%.

[0011] Preferably, the anti-tension structure layer adopts a Kevlar braiding structure, and the braiding density is 60% to 70%.

[0012] Preferably, the sheath layer adopts soft high-flame-retardant polyvinyl chloride.

[0013] Compared with the prior art, the flexible degradable insulated medium-frequency cable has the advantages that (1) compact and light, saving space: the outer diameter of the cable is smaller, the weight is lighter, and the occupied space is also less. This makes it more flexible when installing and wiring, especially suitable for space-limited environments. Its compact design not only reduces the demand for space, but also simplifies the overall network construction.

[0014] (2) Excellent mechanical properties: the cable has superior tensile and bending properties, which enables it to easily cope with various construction environments and conditions. Whether it is straight laying or in situations that require frequent bending, the cable can maintain its structural integrity and performance stability.

[0015] (3) Multifunctional transmission, high adaptability: the cable can provide multiple transmission technologies at the same time, with high compatibility and strong expandability. This makes it widely applicable in different fields and scenarios, including but not limited to aviation, ships, industrial automation, etc., with wide applicability.

[0016] (4) Excellent shielding performance: outside the communication and data transmission core, the cable adopts high-density copper wire braiding, providing excellent shielding performance. This design is particularly suitable for use in high-frequency environments, effectively reducing electromagnetic interference, ensuring stable signal transmission, ensuring data integrity and communication reliability.
