TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric power construction, more particularly to a multi-gradient reusable pole tower with adjustable tower head height. BACKGROUND

[0002] When the power transmission line scheme is "T-connection", "pi-connection" or connection modification to the existing line, a new "temporary transition" pole tower is usually needed for construction, but after the transition work is completed, the pole tower foundation needs to be scrapped, causing serious resource waste. At present, in order to avoid the above-mentioned large-scale resource waste, many companies have self-stored a batch of reusable pole towers, but due to the great uncertainty of the actual engineering pole tower height, for the same tower type, a large number of height pole towers need to be prepared, and due to the large size of the tower leg and the large number of components, the weight of the tower leg accounts for a high proportion, which has a great adverse effect on the economic benefit of the multi-height temporary transition pole tower.
