[0022] It should be noted that the commonly used single-strand conductor wire has a relatively large energy consumption when processing and transmitting high-frequency signals; when there is alternating current or an alternating electromagnetic field in the conductor, the current distribution inside the conductor is uneven, and the current is concentrated in the "skin" part of the conductor, that is, the current is concentrated in a thin layer on the outer surface of the conductor. The closer to the surface of the conductor, the greater the current density, and the actual current inside the conductor is smaller; as a result, the resistance of the conductor increases, and its loss power also increases; the present utility model improves the structure of the wire 100, reduces the loss power, realizes reducing the influence of impedance on the transmission of high-frequency signals of the data cable, further solves the problems such as the high consumption of the wire 100 caused by easy heating affected by the skin effect, and at the same time improves the signal transmission and service life of the wire 100, etc.

Each section of the wire must be connected as a whole. The connector 300 of the wire 100 is the end and the terminal head.
