HW3/S2500 Wind Turbine Introduction
HW3/S2500(107) wind turbine:
The HW/S2500(107) wind turbine with typhoon resistance performance , designed for the wind farm with low annual average wind speed and high extreme wind speed. The annual average wind speed of the turbine is 8.5 m/s, and it can withstand extreme gusts of 70 m/s. This turbine has a high anti-corrosion level and is mainly suitable for coastal and some inland areas.
HW3/S2500(141) wind turbine:
The HW3/S2500(141) wind turbine is designed for low wind speed areas. The designed average annual wind speed is 7 m/s, and it can withstand 50 year extreme 3s gust wind speed of 52.5 m/s. To ensure the axiality between the front main-bearing and the rear main-bearing, the two main-bearings installed in one bearing housing. This designation of transmission with compact structure and high reliability, which can effectively extend the service life of the main-bearings and gearbox.
HW3/S2500(141) wind turbine:
This is an economical wind turbine which designed for low wind speed areas. The rotor diameter of the turbine is 141 m, which is the largest rotor diameter of 2.5MW wind turbine in the domestic market. The designed average annual wind speed is 6.5 m/s and it can withstand 50 year extreme 3s gust wind speed of 45.5 m/s. The transmission adopts the classic three-point support structure, is very compact and easy to maintain. Due to the large rotor diameter, This turbine is excellent for power generation.
HW3/S2500(147) wind turbine:
The HW3/S2500(147) wind turbine was upgraded from HW3/S2500 (141) turbine. Except for the blades , the other structures of the two turbines are the same. It helps improve economy and shorten research and development cycles. This turbine has good power generation performance, and lower production cost and maintenance cost.
