GE introduces new space frame tower for wind turbines

Global power equipment manufacturer General Electric (GE) has introduced its new space frame tower for multi-megawatt wind turbines.

The five-legged enclosed lattice tower of 139m height can be built on accessible locations using a logistics-friendly model of standard shipping methods and on-site assembly.

According to the company, the lattice tower can be assembled at wind farm locations and then wrapped in an architectural fabric to provide familiar solid structural aesthetics.

The new tower, which has been designed to improve serviceability, features increased space down-tower, maintenance-free bolting system and custom methods and fixtures for efficient installation and dismantling.

When compared to a traditional tubular tower, the new space frame tower comes with a wide base supported by five legs that provide more room at the base of the tower.

The additional down-tower space is said to allow for storage within the turbine for ease in maintenance, site organization and balance of plant.

GE claims that parts manufacturing can be automated with the space frame tower to optimise quality control of the structure.

The fabric casing of the new tower is durable, weather resistant and eliminates the need for replacement during turbine life, said the company.

GE also introduced its new 2.75-120 wind turbine that has been demonstrated in a full-scale turbine at its prototype site in Tehachapi, California.
