[0013] like Figure 1 The high-performance data communication cable for new energy vehicles shown includes several groups of core wires.

[0014] Each core wire group consists of two bare copper conductors 1 arranged in parallel within a first aluminum foil wrap 2. The bare copper conductors 1 are encased in an insulating layer 3, with a first ground wire 4 disposed between the bare copper conductors 1. The core wires are then surrounded, from the inside out, by a second aluminum foil wrap 5, a tinned copper braided shield 6, and a sheath 7.

[0015] In this embodiment, four groups of core wires are arranged in a ring within the second aluminum foil wrap 5. The two bare copper conductors 1 within each group of core wires each include a first conductor located near the center of the second aluminum foil wrap 5 and a second conductor located near the circumference of the second aluminum foil wrap 5. This compact structural design maximizes signal transmission performance within a limited space. A second ground wire 8 is provided within the second aluminum foil wrap 5 to further enhance the electromagnetic compatibility of the cable and ensure the stability and reliability of data communication in complex electromagnetic environments. A filler 9 is also provided within the second aluminum foil wrap 5. In this embodiment, the filler 9 is provided at the center of the second aluminum foil wrap 5 and between the core wires near the second aluminum foil wrap 5 (the filler 9 is not provided where the second ground wire 8 is provided).

[0016] The high-performance data communication cable for new energy vehicles of this embodiment has the following advantages:

[0017] (1) The conductor is made of high-purity bare copper conductor, which has excellent conductivity and low resistivity. It can transmit data signals efficiently and stably, meeting the needs of new energy vehicles for high-speed, high-bandwidth data communications, while ensuring the accuracy and reliability of signal transmission.

[0018] (2) The insulation layer is made of high-density polyethylene (HDPE) material, which has excellent insulation performance, good wear resistance and tear resistance, as well as outstanding heat resistance and cold resistance. It can maintain stable electrical performance under extreme temperature conditions, ensure the accuracy and reliability of data communication, and meet the high standards of new energy vehicles for data communication cables.

[0019] (3) The shielding structure of aluminum foil plus ground wire. The aluminum foil layer can effectively isolate external electromagnetic interference and protect the purity of signal transmission, while the ground wire provides an additional current discharge path, further enhancing the electromagnetic compatibility of the cable, ensuring the stability and reliability of data communication in complex electromagnetic environments, and meeting the high performance requirements of new energy vehicles for data communication cables.

[0020] (4) Fillers 9 are innovatively added to the internal structure. These fillers not only ensure the roundness and stability of the cable structure, effectively prevent the displacement and damage of the internal conductor during bending or pulling of the cable, but also improve the overall mechanical strength of the cable, so that the cable can still maintain excellent performance in complex and changing installation and use environments.

[0021] (5) A tinned copper wire braided shielding layer is used. This design not only provides excellent electromagnetic shielding effect, effectively resists external electromagnetic interference, and ensures the pure transmission of data signals, but also enhances the corrosion resistance and oxidation resistance of the cable, thereby improving the overall durability and service life of the cable, and perfectly meets the high performance and high reliability requirements of new energy vehicles for data communication cables.

[0022] (6) The sheath 7 is made of TPU, which has excellent wear resistance, tear resistance and weather resistance. It can effectively resist the erosion of external environment such as oil stains, moisture, ultraviolet rays, etc., while maintaining good flexibility and flame retardancy, providing all-round protection for the cable.

[0023] In summary, the high-performance data communication cable for new energy vehicles of this embodiment can ensure the stability and security of data communication and meet the stringent requirements of new energy vehicles for high-performance data communication cables.
