Features
Rated voltage 12V\24v
Design-optimization in our own wind-tunnel
Permanent magnet-generator
Very good start-up performance due to low cogging torque at 2,2m/s wind speed
External hybrid controller for wind- and solar-energy with multi-function display
and integrated electronic/manual stop switch
Universal application for low, middle and high wind
Hand laminated, UV-resistant carbon blades, successfully tested according to
DIN EN 61400-2 at hurricane speed 122km / h (5480 rpm, with almost Speed of
sound at the blade tips). See for this our video clip of the wind-tunnel test.
The usual, standard blades from other manufacturers are made from granulate
using injection moulding techniques to achieve a fast production time, but lacking
the durability especially after UV exposure associated with the potential risk of blade
fracture. Our blades are handmade incorporating high tensile carbon fibre mats.
This is a more labour intensive process resulting in an optimized blade profile at
the lowest weight, which combines a very quiet operation, blade longetivity
and an exceptional safety record.
Aerodynamic design from aircraft-engeneering
Low noise
Durable and low maintenance by external controller and high-quality components
Well used in
Housing, office, farm and factory
Telecommunications Station
TV Transfer Station
Monitoring Station (military, hydrology, observatory)
Wind solar hybrid street light system

Hefei Wind Wing Energy Technology Co., Ltd. is the earliest one of the R & D wind energy generation equipment in China. Our company develops under the support of Chinese Wind Power Association, depends on Chinese Academy of Sciences Institute of Automation the long-term technical guidance and the close cooperation. We take the "the national initiative energy crisis subject" as our development goal. Now we have a strong R&D group, and researched and developed a profession leading WIND AND SOLAR SUPPLEMENT new energy generating system.
People are paying attention to our products, for the features: Green energy, environmental protection, regenerative and natural energy, etc. Our systems have widely applied in so many fields: City view, communication station, military army, science & education, weather department, fishing vessel, irrigation, oil well, seawater desalination, open country inspection, and so on.
As the first domestic enterprise developing the WIND AND SOLAR SUPPLEMENT new energy, we have passed ISO9001: 2000 quality and management system certification and EU CE certification. Our WIND AND SOLAR SUPPLEMENT new energy range systems are faithful and popular in the domestic and foreign clients, becoming the profession leading enterprise.
We always persist in the enterprise culture of "being a creditable person, live a worth while life", we insist on providing vast customers with the first-class goods, the top-notch technology heart and soul. We heartedly wish to intensively co-operate with old and new customers for greeting together with the challenge WIND AND SOLAR SUPPLEMENT new energy spring arrival!
