Cross Flow Fan blade industry representation ’shortage’ tide

"Cross Flow Fan" fan blade industry reproduction "shortage", - has experienced in recent years after overcapacity, which is the condition of the fan blades of wind power since the 2008 "Great Leap Forward", after a lapse of six years a shortage again. According to research from June 2014, domestic wind turbine blade industry began a "shortage" situation, a lot of wind power machine manufacturers need to plant in front of the blades "queue" to get the blades, especially large leaves. It is reported that, with the installed capacity of wind farms to transfer low wind speed areas, the length of a single 2MW wind turbine blades more than 50 meters long. In the case of the explosive growth in demand, more than 50 meters large blade mold a relatively small number of longer production cycle, resulting in tight supply. Meanwhile, the raw material of the blade appear insufficient domestic supply of epoxy resin, some need to be imported, long procurement cycle, supply has exacerbated the tension. According to research, down by wind power electricity price is expected to affect the total 2014 annual wind power construction scale of the major investors scheduled nearly 25GW, the actual installed capacity could reach and exceed 20GW, an increase of more than 25%. According to incomplete statistics, this year half the new wind power installed capacity of about 5.5GW last year and compared to an increase of nearly 30%.
