High-power high-frequency cable

The utility model relates to a high-power high-frequency cable. The high-power high-frequency cable sequentially comprises a wire core, an insulating layer, shielding layers and an armored layer from inside to outside, wherein an insulating sheath layer is arranged between the shielding layers and the armored layer. The high-power high-frequency cable has the beneficial effects that: 1, the pressure resistance of a product is enhanced, namely that by adoption of the insulating layer and the insulating sheath layer, the pressure resistance of the cable is enhanced, and the cable can work for 5 minutes at a voltage of 7,500V and can not be punctured; 2, the interference immunity of the product is improved, namely that two shielding layers are clamped between the insulating layer and the insulating sheath layer, so that the structure greatly enhances the interference immunity of the cable; and 3, the tensile strength of the product is improved, namely that an inner layer armoring wire and an outer layer armoring wire are wrapped outside the insulating sheath layer, the armoring knitting directions of the inner layer wire and the outer layer wire are opposite to each other, the inner layer wire is wrapped through leftward rotation, and the outer layer wire is wrapped through rightward rotation.
