The invention provides a solid sealing pole capable of improving the electrical insulation performance. The solid sealing pole comprises a sleeve and a vacuum interrupter. The vacuum interrupter is provided with an upper inlet end and a lower outlet end. A lower outlet conducting rod is arranged in the front of the inner side of the sleeve. A second power picking sensor in conduction connection with the upper inlet end and an alternating current voltage sensor in conduction connection with the upper inlet end are fixedly implanted into the back inner wall of the sleeve. A first power picking sensor in conduction connection with the lower outlet conducting rod and an alternating current sensor which sleeves the lower outlet conducting rod are fixedly implanted into the front inner wall of the sleeve. According to the invention, the solid sealing pole can pick power to provide power for the operation of a control terminal and a circuit breaker, is capable of collecting current and voltage signals, and especially small voltage signals and small current signals, and is used to monitor, protect and measure voltage, current and power loss in a power distribution network; early bulky equipment is miniaturized; the level of outdoor protective capability of the electrical insulation performance is improved; the installation of a power grid is simplified; and the connection reliability is improved.
