The invention relates to a solid-sealed polar pole and solid insulation ring main units using the solid-sealed polar pole. The solid-sealed polar pole comprises an insulator. A switch arc extinguish chamber and a circuit breaker arc extinguish chamber are vertically arranged inside the insulator. A switch wire holder connected with the static end of the switch arc extinguish chamber is arranged inside the insulator. A circuit breaker wire holder connected with the static end of the circuit breaker arc extinguish chamber is arranged inside the insulator. The switch wire holder and the circuit breaker wire holder are vertically and symmetrically arranged. After the vertically symmetric structure is adopted, normal use of the switch wire holder and the circuit breaker wire holder is not affected after the solid-sealed polar pile is turned over by 180 degrees. When the position of a disconnecting switch needs to be changed, for example, when the disconnecting switch needs to be arranged below a circuit breaker, the solid-sealed polar pole can be used only by being turned over by 180 degrees, the solid-sealed polar pile does not need to be cast again with other insulator casting molds, and the solid-sealed polar pile is good in universality and applicable to the different ring main units.
