Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention will be further described.

[0025] Such as figure 1 As shown, the schematic diagram of the new fully insulated 35kV cable climbing pole device of the present invention. The new fully insulated 35kV cable pole installation includes poles and three-phase cables, and the three-phase cables are fixed and erected on the poles through strain-resistant clamps. The tension clamp is covered with a tension clamp insulation cover, and the upper end to the lower end of the pole is provided with a cross-arm bracket for the lower lead of the three-phase cable in turn. The cross-arm bracket includes a cross-arm insulator and a cross-arm base frame. Fixed on the pole, the cross-arm insulator is fixed on the cross-arm base frame, and the cross-arm insulator is covered with a cross-arm insulation cover, and the lower lead of the three-phase cable is electrically connected to the cross-umbrella cable joint through the...

Abstract

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.

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...
