Wind Energy 275 kW Wind Turbine
Flexible and Lightweight
Wind Energy 275 kW Turbine Diameter of the rotor 32 m Height 55/60 m Energy until the world ends The most difficult sites to equip with infrastructure turbines are precisely those that need energy from an independent, reliable and economical source of energy.
Lightweight Structure With a weight of 20 tons with height of 55 meters, Wind Energy 275 kW shows unique ratio performance/weight: it is 2 times more light per kW than conventional wind turbine.
Compact Nacelle 2 nacelles fit in one standard container of 20'.
Rotor Blade - Exclusive lowering System The two-blade design of the Wind Energy 275 kW allows it to be lowered, which allows to perform maintenance, periodic maintenance and cleaning of the blades at ground level. The lowering is done safely in less than an hour by two people, through integrated winch.
Light Guyed Mast Made up of modular elements of 11.88 meters long, it is transported in containers of 40'.
Standalone Installation

All of the turbine is assembled on the ground and then erected with a hydraulic built winch. No crane is required. Only a telescopic forklift is required for assembly.
We have successfully met this challenge. We develop innovative and pragmatic solutions to all inaccessible sites: cyclones, strong salinity ... Like other wind turbines, Wind Energy 275 kW wind turbine is 速 both robust and lightweight. Designed around a guyed , mast,
it is very easy to transport, install and maintain, and shows
Reduced Foundations The use of shrouds reduces drastically the foundations only 15 m3 of concrete, or 80% less concrete compared to a conventional turbine
Hurricane Protection In case of hurricane warning, the speed of lowering operations can secure any wind farm in record time. Once tethered to the ground, the Wind Energy 275 kW can withstand winds of over 300 km/h (Category 5 hurricanes).

High Resistance Blades
Maximizing production areas in hurricanes
The optimized blade performance gives them an excellent performance / weight. The manufacturing of blades, fully integrated, is based on the best current methods: vacuum infusion, finishing by coating, strengthening the leading edge, anti-abrasion strips ...
Through its unique lowering system the Wind Energy 275 kW can be installed on sites where only Class 1 machines could operate. With a rotor diameter of 32 meters located at 55 meters in height, a swept area of 804 m2 is used of the wind power.
Damper Torque A mechanical damper absorbs torque fluctuations. This system allows limiting the stresses in the driveline, and smooth up the electrical signal generated.
Regulating by VVT blade (pitch) Anticorrosion treatment
The variable pitch control allows to operate a direct coupling to the network,specifically regulate the power output and eliminate any risk of overspeed.
The mast and all exposed parts are protected by a special coating. It ensures effective protection of the machine throughout its lifetime, including humid atmospheres, salt, or friction corrosion.
Security Systems All security systems to meet international standards: • braking autofeather, backed by units Relief in case of independent network cut • Lock rotor to ensure operations Maintenance safely • Protection against lightning
Robust Design All parts of the Wind Energy 275 kW are realized in the finest materials. Most components are standard parts, widely used in many industrial applications, ensuring reliability. Castings, including the hub, are spheroidal graphite cast iron.The Wind Energy 275 kW is designed to support 365 network outages per year, against only 20 per year for a conventional turbine.
Industrial PLC The PLC (Programmable Logic Controller) is located in the local electric mast. It operates in real time all the necessary parameters: • Measures wind (direction and speed) • machine parameters (speed of rotation of the rotor blade pitch, orientation of the crown, current output of generator ...)

The GEV MP is equipped with a robust generator squirrel cage, produced by an industry leader. It is designed to operate in the most rigorous conditions: • -20 ° C to +50 ° C • 100% relative humidity • Marine Atmosphere (less than 100 m from shore) • Protection class IP55 • Specific treatment of the rotor and the stator against corrosion in the tropics (screws, hood fan and stainless grease)
Sensors and protected controllers • varnish protecting electronic components from condensation • High level Connectors of sealing (IP 67) • Electromagnetic Protection
Resistance to any climate With 20 years of field experience in the world, we have endowed the Wind Energy 275 kW assets necessary for a world traveler. Fully protected from the aggression of natural elements, even in the harshest climates, it will ensure regular production and reliable throughout its life.

Oscillating Hub With its laminated elastic joint (rubber / steel), this technology reduces 35% of the stresses in the turbine and hence its weight. It reduces maintenance costs involved, and ensures a longer lifespan.
Robustness and Sustainability A wind turbine suffers extreme mechanical stress. This is especially true in hurricane zone ... The Wind Energy 275 kW is equipped with the most ] robust parts and damping systems more efficient. This is the secret of his extreme reliability, even on the highest sales.
