Problems solved by technology

Among them, the single-core cable has a serious skin effect when transmitting high-frequency alternating current; the core wires in the multi-core cable are not designed to be equipotential, and insulation treatment is required between the core wires, making the outer diameter of the cable too thick, Moreover, the skin effect of multi-core cables is still serious when transmitting high-frequency alternating current.

Abstract

The invention discloses a cable, which comprises an insulation sheath and at least two wire groups coated by the insulation sheath, wherein each wire group comprises at least two wires, and each two wires is arranged in a mutual insulation mode. In the technical scheme of the invention, through arranging the at least two wires in each wire group in a mutual insulation mode, problems of large powerloss and high temperature rise and the like caused by skin effects in transmission of high frequency alternating current in the traditional cable can be well solved, and the cable thus has low temperature rise and good transmission effects.

Description

technical field [0001] The invention relates to the technical field of high-frequency current conduction, in particular to a cable. Background technique [0002] As a brand-new charging method, wireless charging technology can charge electric vehicles with high power. This charging method is safe and convenient. The high-power wireless charging technology of electric vehicles is mainly realized by magnetic coupling. The transmitting device transmits high-frequency alternating current to the receiving device through the electromagnetic field, and the receiving device rectifies the received high-frequency alternating current to form direct current to charge the battery of the electric vehicle. , therefore, the transmission of high-frequency alternating current plays an important role in wireless charging technology. [0003] At present, the traditional high-frequency AC power cables used in the field of wireless charging technology include single-core cables and multi-core ca...
