SW-3kw Wind Turbine

Main Parameter:

 

Model: SW-3KW fixed pitch Yawing wind turbine

 

3KW wind generator,residential 3kw wind turbine is fixed pitch yawing wind turbine,is an equipment to convert wind energy into electric power which is changed into storage battery group. 3kw wind turbine can be widely used in rich wind areas but without normal energy supply from any power system .It is capable of providing power for lighting,TV, telecommunication equipment and so on

 

 

A． Purpose

The electricity generated by 3kw wind turbine generator can be stored in batteries, through inverter the DC can be changed into AC for power supply; it can also be used as a distribution power supply to delivery electricity to AC380V/AC220V grid.

The aim of Application

Use wind energy to generate electricity and charge into storage battery group. Through the multi-voltages power supply system, the electricity can be changed into DC and AC used for illumination, home appliances,communication devices and electric tools.

 

Product Advantages

SW-3KW wind turbine generators are totally meeting European standard and America Standard, like IEC 61400 series standards, and CE certified, ISO9001 and CAN/CSA-F416-87 (R2004)/ CAN/CSA-F417-M91 (R2004), with the perfect appearance, performance and the most competitive price, have already received the most popular from oversea and domestic market customers, hope you like our new concept style series wind turbine, since its real excellence

 

Ten points advantages:

 

 ※Advantage one: Exposed parts are made by stainless steel and have passed special long time effective rust-protection treatment, so the outside of those parts don’t need any maintenance cost.

 ※Advantage two: The generator adopts high grade SKF bearings and high grade lithium grease, the bearings need to be checked after operating first 30000h, if it is necessary, just need to paint some grease into bearings. Besides, generator is brush less type.

 ※Advantage three: When the wind over-speed, the speed regulation methods automatic by electromagnetic braking and tail yawing Auto-furl brake System. Hand handle can stop wind turbine manually as well when there is gale forecast. 3 kind brakes system promise system More security.

 ※Advantage four: The generator can keep working with lower wind velocity-even breeze, just need 2.5-3.0m/s(2-grade) to start-up.

 ※Advantage five: If windy enough it could generate more power than others same types wind mill.

 ※Advantage six: It can work in wicked environment that is 50m/s storm, other some types only bear at most 45m/s storm.

 ※Advantage seven: Blades manufacture according to the airplane propeller structure and craft, very durable. Connections between Blades and generator with flexible material, run smoothly without vibration.

 ※Advantage eight: Optimized wing design, by wind tunnel test for detection, high-efficiency low-noise; Closed transmission slip ring, cable is not wrapped

 ※Advantage nine: Folding free-standing tower. Easy to install and repair. Also have good-looking appearance, especially suit for installing in resort, Scenic such place as Landscape.

 ※Advantage Ten: super long life time span, can be used more than 20years.
