The invention relates to a full-insulated 35kV cable climbing pole device. The full-insulated 35kV cable climbing pole device comprises an electric pole and a three-phase cable; the three-phase cable is fixedly arranged on the electric pole in a bridging manner through a strain clamp covered by a strain clamp insulation cover; a cross arm bracket of the lower lead of the three-phase cable is arranged on the electric pole; the cross arm bracket comprises a cross arm insulator; the lower lead of the three-phase cable sleeved by an insulation sleeve is in lap joint through the cross arm insulator and electrically connected with a cross-umbrella type cable joint covered by a cable joint insulation cover; the insulation sleeve comprises a plurality of insulation sleeve units connected end to end; a transverse arrester is arranged on the electric pole over the cross-umbrella type cable joint; the transverse arrester comprises a grounding end of the arrester and a high-voltage end of the arrester covered by an arrester insulation cover; and a grounding suspension ring covered by a grounding suspension ring insulation cover is arranged on the upper lead of the cross-umbrella type cable joint. According to the full-insulated 35kV cable climbing pole device disclosed by the invention, the insulation safety of a high-voltage circuit is improved in a manner of covering the insulation covers on the high-voltage circuit; and the full-insulated 35kV cable climbing pole device has the characteristics of being full-insulated in circuit and high in high-voltage power transmission insulation safety.
