If China fan quality problem is the coupling of many factors
If China fan quality problem is the coupling of many factors, it is difficult to recognized as homebred fan quality closes nevertheless, so in this behind the core technology lack is Chinese wind around not past "trouble".
Foundation weak r&d let copy foreign technical drawings of Chinese wind almost the whole industry status.
Long-term since, domestic only valued the installed capacity and the growth of the wind generator upgrading, international wind turbines manufacturers forerunner of wind power are more see severe electricity costs. "We have always believed in fan 20 years of life cycle, fan reliable operation and effectively reduce KWH cost is to help the clients to realize the benefit of the key." The world¡¯s largest fan manufacturers wes tower si (in the Chinese market is ranked) President tang fro said.
KWH cost refers to a fan during its lifetime (usually of 20 years), integrated manufacturing, power generation, and maintain all costs, and spread a kilowatt-hour costs.
"We believe, based wind generators on the life cycle cost can represent the true costs of fan." Tang fro said. And here, China fan "technology with foreign capital enterprise connotation" fan compared also has the very big disparity.
However, in the past for a very long time, this kind of idea cannot be Chinese clients to accept. "Daniel alves tower si products is indeed a good thing, but if the price can low is better." This almost represents the most wind owner¡¯s real mentality. It is on this general knowledge, China wind turbine generator fan with its relatively cheap price and relatively outstanding cost-effective advantage rapidly a portrait of stope soil, large-scale occupied domestic wind field.
However, China wind turbines manufacturing fan of this advantage is lost. By 2010, when China advanced world¡¯s second-biggest fan installed market, China¡¯s wind power market overproduction and new installed slowing trend obviously. China¡¯s wind power market or start farewell pure scale for WangShiDai, electric field owner began to examine the quality, technology and practical operation cost electric. China fan despite foreign fan cheap price is about 20%, but suffer frequent "indisposition" and high maintenance costs gradually began to rewrite the chiral let owner order.
For China¡¯s fan small wind turbines manufacturers are concerned, they over the past five years, the first round of developing rely on to buy foreign technical drawings and low cost of manufacture, the rapid preempted the market share, but in the second round of the slowdown in developing wind power, technical congenital deficiency disadvantage has begun appears gradually.
