DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0018] Please refer to Figures 1-3, the present utility model discloses a vehicle - used shielded cable, which includes a wire core 1 and a strengthening core 2. The wire cores 1 are evenly arranged around the outer part of the strengthening core 2. A thin aluminum foil wrap 3 is wrapped around the outer part of the wire cores 1. There is a filling gap 11 left between every two wire cores 1, and an inner petroleum jelly layer 4 is filled in the filling gap 11. A thin polyester tape 5 is wrapped around the outer part of the thin aluminum foil wrap. A PP rope wrap 6 is wrapped around the outer part of the thin polyester tape 5, and an outer petroleum jelly layer 7 is filled between the PP rope wrap 6 and the thin polyester tape 5. A copper braid 8 is wrapped around the outer part of the PP rope wrap 6. The internal filling with two layers of petroleum jelly can play a role in cooling the heat of the wire. The thin aluminum foil wrap 3 and the copper braid 8 arranged inside can reduce electromagnetic interference and electromagnetic radiation. At the same time, their metallic properties can also serve as heat transfer media, playing a certain role in heat conduction, which can avoid heat stacking in the central part, ensure the stability of the power transmission process, and will not generate excessive heat. While ensuring the normal operation of the cable, it also ensures the safety of the power system. An XLPE insulating jacket 9 is wrapped around the outer part of the copper braid 8.

[0019] Specifically, the number of the wire cores 1 is 3 strands, and their cross - sections are fan - shaped.

[0020] In this implementation scheme, the three wires often used in the circuit are the live wire, the neutral wire, and the ground wire respectively. The application of three - strand wires can prevent electric shock accidents caused by electric leakage during the application of electrical equipment.

[0021] Specifically, one side of the wire core 1 is provided with an edge 12, and adjacent wire cores 1 are mutually attached through the edge 12.

[0022] In this implementation scheme, when the wire cores 1 are arranged around the outer part of the strengthening core 2, the edge 12 mainly plays a positioning role to ensure the attachment between every two wire cores 1.

[0023] Specifically, the wire core 1 includes a bare copper conductor 13 and a PE insulating layer 14, and the PE insulating layer 14 is wrapped around the outer part of the bare copper conductor 13.

[0024] In this implementation scheme, the wire core 1 is the name of the internal conductive part of the cable. It is wrapped in the insulating layer of the cable and is composed of multiple stranded wires.

[0025] Specifically, grooves 91 are formed on the XLPE insulating jacket 9, and the grooves 91 are evenly distributed on the outer surface of the XLPE insulating jacket 9.

[0026] In this implementation scheme, the grooves 91 are assembly structures for the later addition of steel wires 92.

[0027] Specifically, steel wires 92 are embedded in the grooves 91, and the upper parts of the steel wires 92 are exposed outside.

[0028] In this embodiment, the steel wire 92 can mainly improve the strength and tensile performance of the cable, enabling it to withstand greater tensile force and external pressure, and increasing the service life of the cable.

[0029] During use, two layers of petroleum jelly are filled inside, which can play a role in cooling the heat of the conductor. The thin aluminum foil wrapping 3 and copper braid 8 provided inside can reduce electromagnetic interference and electromagnetic radiation. At the same time, their metallic properties can also serve as heat transfer media, playing a certain role in heat conduction, avoiding heat accumulation in the central part, ensuring the stability of the power transmission process, not generating excessive heat, ensuring the normal operation of the cable while also ensuring the safety of the power system.

[0030] In summary, for this vehicle shielded cable, two layers of petroleum jelly are filled inside, which can play a role in cooling the heat of the conductor. The thin aluminum foil wrapping 3 and copper braid 8 provided inside can reduce electromagnetic interference and electromagnetic radiation. At the same time, their metallic properties can also serve as heat transfer media, playing a certain role in heat conduction, avoiding heat accumulation in the central part, ensuring the stability of the power transmission process, not generating excessive heat, ensuring the normal operation of the cable while also ensuring the safety of the power system.
