The Product
GOLIATH Wind 3-100 wind turbine generator
GOLIATH Wind turbines are characterised by simplicity, high redundancy and fault-tolerance. Due to gearless transmission, the high power generation efficiency is achieved without the cost of power-consuming cooling system: GOLIATH turbines use ambient air-cooling. A two-bearing concept provides sovereign load distribution through a king pin. The generator rotor runs inside the stator, housing in a cover ring that surrounds a spacious passageway for access. GOLIATH Wind places great importance to accessibility for maintenance personnel to all components, including the generator and the turbine hub.
