Embodiment 1

[0028] According to an embodiment of the present invention, a copper pipe is provided. Such as image 3 As shown, this embodiment includes a first conductor 10 and a second conductor 9, and the second conductor 9 is axially sleeved on the periphery of the first conductor 10; between the first conductor 10 and the second conductor 9, filled with first Insulation layer: the outer periphery of the second conductor 9 is coated with a third insulation layer.

[0029] In this embodiment, the distance between the first conductor 10 and the second conductor 9 is relatively short, the flow direction of the short-circuit current in the first conductor 10 is opposite to the flow direction of the short-circuit current in the second conductor 9, and the short-circuit current in the first conductor 10 The electric field and the direction of the magnetic field produced by the short-circuit current are opposite to the electric power plant and the direction of the magnetic field produced by t...

Embodiment 2

[0031] Different from the above embodiment, in this embodiment, if Figure 4 As shown, the copper tube includes a first conductor 10, a second conductor 9 and a capacitor 8, wherein the second conductor 9 is axially nested on the periphery of the first conductor 10, and the capacitor 8 is axially nested on the periphery of the second conductor 9 ; The first insulator is filled between the first conductor 10 and the second conductor 9, the second insulator is filled between the second conductor 9 and the capacitor 8, and the periphery of the capacitor 8 is covered with a fourth insulating layer.

[0032] In this embodiment, the capacitor 8 is axially sleeved on the periphery of the second conductor 9, which can further reduce the inductance and impedance of the copper tube, so as to further reduce the reactive power loss of electric energy on the copper tube and increase the active power. power.
