Problems solved by technology
The floor area of the cable climbing platform is usually directly affected by factors such as relocation compensation, greening, crossing with other municipal pipelines, etc., resulting in construction difficulties, which is particularly prominent in areas with a high degree of urbanization
For example, the currently commonly used 110kV cable pole platform has a size of 4.6m×8.8m. Due to its large footprint, its actual construction in Shanghai often results in high compensation costs due to conflicts with urban greening and underground municipal pipelines. , Construction progress is affected, etc.

The invention discloses a city cable-pole climbing device. The city cable-pole climbing device is arranged at one side of a cable terminal pole. The upper end of the cable terminal pole is provided with three-phase overhead lines. The city cable-pole climbing device comprises three sets of line insulator strings corresponding to the three-phase overhead lines. The upper ends of the three sets of line insulator strings are connected with three wires of the three-phase overhead lines respectively. The lower ends of the three sets of line insulator strings are connected with corresponding arresters and cable terminals respectively. Cables are arranged inside aluminium-alloy huff protection tubes. The other ends of the aluminium-alloy huff protection tubes are connected with underground cable channels. The cables enter the underground cable channels through the aluminium-alloy huff protection tubes. Compared with the existing cable-pole climbing platform, the city cable-pole climbing device has the advantages that the occupied area of the city cable-pole climbing device is smaller and and the consuming material thereof is less, and the city cable-pole climbing device is more portable and has obvious advantages in prosperous cities.
Description
technical field [0001] The invention relates to the technical field of cable laying, in particular to a cable climbing pole device for cities. Background technique [0002] In the prior art, a climbing pole device is required when the transmission line is converted from cable laying to overhead line erection, and the current cable climbing pole is often installed on sidewalks and green areas. The floor area of the cable climbing platform is usually directly affected by factors such as relocation compensation, greening, crossing with other municipal pipelines and other factors, resulting in construction difficulties, which is particularly prominent in areas with a high degree of urbanization. For example, the currently commonly used 110kV cable pole platform has a size of 4.6m×8.8m. Due to its large footprint, its actual construction in Shanghai often results in high compensation costs due to conflicts with urban greening and underground municipal pipelines. , Construction...
