Proprietary Technology Costs Influences:

Proprietary Technologies	Design Features	Influences on costs and benefits
Soft technology	Passive yaw system	Yaw is a term used to describe the mechanical system of aiming the turbine blades into the wind. The GC China Turbine has a passive yaw system, eliminating the need for mechanical yaw braking system. The passive yaw reduces loads on the tower and foundation thereby allowing for a lighter tower, and smaller foundation as well as reducing the manufacturing costs for a complete machine.
	Teeter-style hub	The teeter-style hub reduces the negative effects of imbalanced air pressure on the blades not unlike the function of rubber engine mounts in a motor vehicle. The Rubber bushings greatly reduce twisting loads on the transmission chain, tower and other components and increases the service lives of these components. This technology is characterized by rubber mountings of the blades to the main gearbox.
	Soft tower	The soft tower is lighter than a stiff tower so as to directly save raw material costs. This is achieved by designing a tower that is allowed to flex during operation. This is partially possible because the turbine and blades are significantly lighter than a 3-blade system.
Compact transmission chain	Support tube	Generator, gearbox and high-speed shaft are directly connected which greatly improves the service lives of the key components in transmission chain.
Compact transmission chain	Integrated gearbox	Because GC China’s design eliminates the main shaft and main bearing of 3-bladed designs, the Company enjoys a lower cost profile and eliminates a significant component sourcing bottleneck. Integrated main shaft has a longer service life, improves the availability rate and reduces maintenance costs.
Overall damping design	Teeter and hub rubber elements, nacelle chassis rubber elements	Significantly reduces fatigue loads on all moving parts, extends the service life and reduces operational costs.
Condition monitoring	Conducts maintenance according to actual conditions, instead of preventive and post-fault maintenance	Extends service life of wind turbine and reduces maintenance costs.

The 2-blade wind turbine is designed with technologies utilizing a flexible, “soft” concept, compact transmission chain, superior damping, condition monitoring and many other proprietary technologies that reduce vibration and overheating, lower installation and transportation cost as well as improve service life and utilization rate. The resulting benefits of high wind turbine quality, low manufacturing cost, and cheaper installation and maintenance.

Even with imported key components, the product has a cost advantage over other products of the same class on the market. In order to sustain the low-cost advantage, the company has been actively seeking the localization of components. The company has identified domestic suppliers of all key components, making it possible to complete the assembly utilizing 100% Chinese manufactured parts. With this localized part supplies, the manufacturing costs are greatly reduced and help to enhance the low-cost advantage of the GC China Turbine Corp.’ product.

GC China Turbine Corp.’ advantage is a combination of simple cost effective design and high quality Chinese components. In many cases, these parts come from Chinese factories operated by European component manufacturers.
