Therefore, wiring harnesses are arranged in the car to transmit the desired power to these electronic devices and signal. For automotive cables, due to their wide distribution range, large power consumption, and high corresponding voltage, higher requirements are put forward for the high-voltage and high-temperature resistance of the wiring harness. In addition, the electromagnetic radiation brought by high-power electrical appliances is also relatively large. , Larger electromagnetic radiation will have a great impact on some precision components in the car. Therefore, higher requirements are put forward for the performance of high-voltage resistance, high-temperature resistance and radiation shielding of the wiring harness. At present, the existing automotive cables only have a single overall shielding layer, which cannot effectively solve the electromagnetic interference between the inner cores of the cable, and has poor shielding ability against external interference, which easily interferes with the signal in the cable and affects the use.
