The invention relates to a novel all-insulated climbing rod device of a 35kV cable. The novel all-insulated climbing rod device comprises an electric pole and a three-phase cable, wherein the three-phase cable is fixedly erected on the electric pole by a strain clamp, the strain clamp is wrapped by an insulation cover, a cross arm support is arranged on the electric pole and comprises a cross arm insulator and a cross arm base rack, the cross arm insulator is wrapped by a cross arm insulation cover, a three-phase cable lower lead wrapped by an insulation sleeve pipe is electrically connected with a cross-umbrella cable connector wrapped by an insulation cover, the insulation sleeve pipe comprises a plurality of insulation sleeve pipe units connected in an end-to-end way, a vertical post type lightning arrester installation support is arranged on the electric pole below the cross-umbrella cable connector, a grounding suspension ring and a vertical post type lightning arrester are arranged on the vertical post type lightning arrester installation support, the grounding suspension ring is wrapped by a grounding suspension ring insulation cover, and the vertical post type lightning arrester is electrically connected with the three-phase cable lower lead and is wrapped by a lightning arrester insulation cover. With the adoption of a mode that a high-voltage circuit is wrapped by the insulation cover, the insulation safety of the high-voltage circuit is improved, and the novel all-insulated climbing rod device has the characteristics of all insulation in circuit and high insulation safety performance of high-voltage power transmission.
