Abstract
A wind turbine tower for mounting tower internals is disclosed. The wind turbine tower may include a plurality of tower sections and each of the tower sections may comprise a plurality of cans axially joined together, the plurality of cans including a top can and a bottom can and intermediate cans. Each wind turbine tower section may further include a top flange attached to the top can and a bottom flange attached to the bottom can. Brackets for supporting the tower internals are welded to the inside wall of each tower section, but the welded brackets are restricted to only the top one or two cans, and the bottom one or two cans, while a the remainder of the intermediate cans do not have any brackets welded thereto. The intermediate cans without any welded brackets may be fabricated of steel plate that is less thick, and therefore less costly.
