General technical innovations WTU 2.05:

• Adaptation of the molded load-carrying front of the frame
• reliability increase at weight-saving by disposing stress concentrator in the form of welded seams and sharp edge
• cost and production time reduction in condition of series manufacture
• frequency converter cabinet removal from the nacelle to the lower tower section
• nacelle mass reduction
• service maintenance ability
• removal of the transformer from the nacelle to a separate block-modular building of the transformer substation at the base of the tower (BMB)
• elimination of the nacelle vibration negative effect on the transformer

Optionally, a turbine version for cold climate is provided, which includes heating of the weather sensors, electronics, lubrication and cooling systems, the use of special cold-resistant materials, expanding the range of lower operating temperatures of wind turbines to -40 °C, as well as simplifying preparation for starting up wind turbines after a long stop at temperatures below 0 °С.
