The invention relates to a shielding cover, an embedded pole with the shielding cover and a solid insulating ring main unit with the shielding cover. The embedded pole comprises an insulator, a switch arc extinguish chamber and a breaker arc extinguish chamber are arranged inside the insulator and connected through a soft connecting part, and the periphery of the part, on the insulator, of the soft connecting part is covered with the shielding cover. The shielding cover comprises an annular plastic body, and metal powder is poured and solidified inside the plastic body, wherein the metal powder and the plastic body are of an integrated structure, and the metal powder is connected with the soft connecting part in an electric conduction mode. In the pouring forming process, the metal powder is good in mobility under driving of plastics, so that the shielding cover is easy to form in a needed shape; in this way, the shielding cover can be used for the embedded pole to shield the soft connecting part and prevent the pointed end of the soft connecting part from discharging.
