| description | The utility model discloses a solid-sealed polar pole and belongs to the technical field of solid-sealed polar poles. The utility model relates to a solid-sealed polar pole, in particular to an outdoor full-sealed solid-sealed polar pole. Solid-sealed polar pole, a vacuum arc-extinguishing chamber is formed in an inner cavity of the solid-sealed polar pole; an epoxy resin casting body is cast at the top of the inner cavity of the vacuum arc-extinguishing chamber; a moving contact screw is arranged at the bottom of the epoxy resin casting body; a contact spring is installed at the bottom of aninner cavity of the vacuum arc-extinguishing chamber. The outer wall of the contact spring is sleeved with a special-shaped silica gel cover. According to the utility model, the vacuum arc-extinguishing chamber is poured in the solid-sealed polar pole; the top of the vacuum tube penetrates through the column body to be connected with the moving contact, the outgoing line conductor is poured in thesolid-sealed polar pole, |
