【Background technology】
Since in electric automobile operational process, the high voltage component of electric automobile can outwards conduct or radiated electromagnetic wave.
And connection network of the high voltage cable as these high voltage components, play the role of conduction/radiation to electromagnetic wave.High pressure in order to prevent
Cable externally causes electromagnetic interference, and the high voltage cable of existing electric automobile is all with shielding shielding electromagnetic waves layer, shielded layer one
As by the way of copper mesh grid and aluminium foil is arranged between the inner insulating layer and external insulation layer in high voltage cable, applied metal net
Electromagnetic induction principle, electromagnetic wave absorption simultaneously forms eddy current decay, to achieve the purpose that electromagnetic shielding.But due to copper mesh or aluminium foil
Shielded layer is there are certain porosity, so its shield effectiveness is undesirable.In addition, the processing of copper aluminium reticulates and is processed into foil-like with aluminium
Larger cost is needed, and during high voltage cable is coated, technique is more complicated, need to successively be coated on copper mesh grid and aluminium foil
On high voltage cable.
In consideration of it, it is really necessary to provide a kind of new high-voltage line with shielding properties to overcome disadvantages described above.
