Superior wind turbines (EWRS) have the main rotor shaft and electrical ... Turbines used in wind farms for commercial production of electric power for businesses & homes

On the larger turbines 80 KW-250KW and 2.3 mega watt turbines we have an engineering firm that will take the project from beginning to end as a turn key installation. Many factors have to be considered prior to the installation. Soil samples for the proper foundation, wind assessments for production, electrical engineering, site planning to your county, grid hook up by your electrical provider. All turbines include inverters and controllers.

With the WES30 Mk1 connected to your farm, business, hotel resort, or any other location, you can harvest the wind and generate your own green energy. In other words, "produce it where you use it"! This powerhouse can produce, depending on the wind availability, an average of 600.000 kWh/year of reliable and renewable energy.

Efficient, Reliable & All-Round

The technology and design of the WES30 is based on the WES18 with noticable differences being its size, the tower and the blades. The WES30 is commonly used as a solitary wind turbine or in small wind farms. It has the reputation of being durable and reliable. The typical Dutch two-bladed rotor has a unique hinged system and a passive blade angle adjustment. This unique mechanism needs very little maintenance. Over 300 units are installed in many different locations, particularly in weak grids. The WES30 Mk1 is now often favored as a "behind-the-meter" wind turbine at business parks and factories. With its choice of towers up to 48 meters, the WES30 has very little impact on the environment and/or nearby airports.

The WES30 is also available as a Hybrid Wind/Diesel system. For more information, please go to our WES Hybrid System page.

Sturdy & User-friendly

The WES30 is a sturdy and user-friendly wind turbine that can be installed and used in logistically difficult locations. Some of the advantages of WES30 are:

Size

With a 30m rotor diameter this a medium sized turbine. With 30, 39 or 48 meter towers it can even be erected with relatively small cranes at difficult locations.

State-of-the-Art

In 2007 WES introduced its new state-of-the-art IGBT Control Cabinet with the commissioning of first two new WES30 Mk1 wind turbines. Since then the new control and inverter cabinet has proven to be an extremely stable platform that outperforms any other turbine in this class.

WES has designed new software and combined this with new IGBT converters from Control Techniques Ltd., bringing the proven WES30 wind turbines into the 21st century.

"Adjustable-pitch,that means wind turbine blades could change the degree when the wind speed to be higher(over the rated wind speed) to keep the wind turbines always in rated speed area.

Third: Automatically Tail folding, When the output power exceeded the limit value, the control box give instruction signal and the battery(12V) supply power to make the steel wire rope in the electric winch to pull the tail vane in a speed of 0.050.1m/s , so as to drive the rotor yawing, when the yawing angle reach to 60°, the “Push rod” will be pushed, brake system will stop the running of rotor.

Wind energy can help reduce your electric bill or completely power your structure.

Most mid size homes use approx, 2000 KWs per month. So if you generated more KWs that month, you would sell it back to your electrical co op. If this continues throughout the year you will receive a check from your electrical co op.

Bearing Many kinds of our parts are imported, e.g. Sweden SKF Bearing:Its costing price is 5~6 times higher than domestic ordinary bearing,and its quality is the one of the best bearings in the world,it could be used at least 15years .Other factory’s only used with domestic ordinary bearing,theirs only could be used few yesrs.
Fastener We use 8.8 10.9 12.9 grade fastener the cost is higher 4times than domestic ordinary fastener.It means the quality is better than others.Other facotry’s only used with domestic ordinary fastener too.

Wind Power Generators: The Basics We all need power, that is not an option. However, there is an option that comes into play with how we receive our power. There are currently some great ways one can power their generator that is not only environmentally safe but economically sound and sustainable. These are important aspects to consider, especially when it comes to one's power source. This is what gives wind powered generators a great advantage over other generators. Because the wind produces kinetic energy to produce electricity, there is no bi-product produced, which means no pollution. There is no fuel to purchase and maintain, just some wind to move a wind turbine. Wind powered generators can produce quite a large amount of energy as well, up to 3,000 watts and more. They are great for remote areas like cabins, remote camping, sail boats, vacation homes, and other applications as well. Wind powered generators will be harder to come across than normal fuel generators but there are many useful applications for them including charging batteries and powering small appliances and tools. Many remote farms and electrical facilities have wind farms that are used to harness power in areas of high wind. Because wind generators are more useful in areas where there is more wind being generated, there are many factors to consider before purchasing or building a wind generator.

First wind is a natural occurrence that can not be controlled. Therefore, the amount of wind and energy produced will vary from day to day. They also often stand out because they have to be placed in high areas or take up large areas of land in wind farms. There have also been complaints with some wind generators on noise and the possible effect on television reception. More aerodynamic designs and technology will eventually minimize this problem.

Now we get to the many advantages, with the most beneficial being the conservation of the environment. A wonderful benefit of wind powered generators is that they are environmentally friendly. They do not produce gases or other by-products like other generators do, that poison the environment and anybody that happens to be nearby. There are enough pollutants in today's society, so choosing a wind powered generator is an environmentally sound choice. Another benefit is that wind energy is harnessed free of charge. Of course you must invest in a generator, but imagine how much money you will save over the years by not paying for electricity? There are also great incentives like tax breaks and lower utility bills that increase these savings. The next factor is that wind is a renewable energy source that will not run out like other sources like oil and coal. with all these advantages and the knowledge of a personal contribution to saving the environment, using just a small amount of wind power through wind generators or purchasing green energy can greatly help.

Department of Energy

We offer 1.5 -KW to 250KW wind turbines for homes and businesses. Off or On grid!

If you are interested in lowering or eliminating your electric bill. If you want to help reduce carbon emissions into the air we breath. And in some cases you can produce enough power to sell back to your electric provider, then you need to research wind energy.

The cost of energy is not going to decrease so why not invest and become a little greener.

Energy waste recovery for homes and businesses was developed by our company and is the best way to see your energy loss, make corrections to those areas consuming wasted energy. Then apply an additional reliable energy source for your future.

Wind turbines are not for everyone however if you own a business or home in a windy area you need to seriously consider wind energy.

A 7mph you will start producing power. Our wind turbines have been tested at 80 mph winds with gusts over 100 mph. Our generators do not have brushes they are magnetic with no gears. Little to no maintenance.

Before investing into wind turbine we highly suggest scheduling a energy thermal inspection first. Locating and repairing those areas in your home or business from energy waste first will help in purchasing the correct turbine system. You maybe wasting 100 to 500 KWs per month and not even know it.

So towers are strong and hard to inflect when strong winds come, the tower body has galvanizing plastic coating outside,so it could work between -40 to 50 c temperature condition,antirust anti-salt corrosive (sea water corrosion) and so on.

Wind turbine-Engine room. Designed of steel and have galvanizing and plastic coating outside, at least 15years anticorrosive and antirust.
