Fully insulated 35kv cable climbing pole device

Abstract

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.

Description

technical field [0001] The invention relates to a 35kV cable climbing rod device, in particular to a fully insulated 35kV cable climbing rod device, which belongs to the field of high voltage cable climbing rod devices. Background technique [0002] The 35kV overhead line has a vast territory and a large transmission power, and it is the backbone of the distribution network transmission. Due to the high rated voltage of the 35kV voltage level wire, if the same 10kV insulated wire manufacturing process is used to add an insulating layer to the surface of the bare wire, the weight of the wire will double, resulting in a double increase in the bending strength of the transmission line insulator and the tensile strength of the pole. As a result, the current overhead transmission line structure cannot bear the load. Because of the above reasons, so far, the national 35kV and above transmission overhead lines still use bare conductors. With the continuous advancement of rural ur...
