The invention discloses a high voltage power distribution cabinet with good shielding performance. An electromagnetic shielding cover body is attached to the surface of the cabinet body of the high voltage power distribution cabinet. The cover body has a sandwich structure, and particularly, a layer of foam aluminum-copper-nickel alloy is clamped between two layers of permalloy plates. Electromagnetic waves in a low frequency band and a high frequency band can be well shielded, electromagnetic radiation of the high voltage power distribution cabinet can be prevented from polluting the environment, and interference of external electromagnetic waves on electrical equipment inside the power distribution cabinet can be reduced; and further, after the surface of the permalloy plate of the cover body is subjected to hydrochloric acid treatment, a nanoplate super hydrophobic structure is formed, self-cleaning, anti-fog, anti-freezing and anti-corrosion protection roles can be played, and the service life of the high voltage power distribution cabinet can be prolonged.
