Wind power industry to accelerate the process of internationalization

China's wind power industry in the domestic market under the strong pull , in a few years time, the rapid growth of the global wind power industry big country . At present, China's wind power [ 3.23% ] industry matured from the exploratory stage , after winning the rapid growth of wind power industry manufacturers gradually accelerate the pace of internationalization of the situation .

Wind trend towards capital to go out

China 's rapid development of wind power market spawned a large number of wind power equipment manufacturing enterprises , also makes the domestic wind power market competition intensifies . Recently released a report pointed out that the domestic wind power machine manufacturing sectors have been hundreds of companies , with domestic rapid growth of wind power installed capacity of wind power machine manufacturers into "Red Sea" , the increasingly fierce price war has begun affect corporate profitability . In this market context, explore new market growth has become a major domestic wind turbine manufacturers an important strategy for future development .

Recently held in Beijing International Wind Energy Conference, China Wind Energy Association Vice President Shi Pengfei said that with China 's rapid development of wind power industry , wind turbines excess capacity , companies are bound to open up the international market. According to Wind Energy Association 's statistics, last year China exported to overseas fans reached 430,000 kilowatts , total exports to foreign markets more than 700,000 kilowatts . Meanwhile, with the improvement of the quality of domestic fans , domestic fans higher price also makes access to international markets accelerated.

According to statistics, in 2012 a total of 19 countries, imports of Chinese fans, which the United States the largest capacity of 328,000 kilowatts , accounting for 47% of China's export machine . Shi Pengfei pointed out that it is not only the machine , parts exports have accounted for a large proportion, even more than the overall export even earlier . Like the first tower , castings , etc., although some quality and technical level is not particularly high, but competitively priced , so many foreign machine manufacturers are willing to import parts from China .

But this is just the device went out , and now China's wind power capital to go is becoming a trend. For example , Longyuan , Trinity , Tianrun were acquired and invested in Canada, USA, Australia, wind power projects . Another way is through the acquisition of foreign companies to achieve global distribution and introduction of technology, such as the wind holding German VENSYS company Darwind Hunan Electric Group acquired the Dutch company . There is a direct establishment of overseas R & D centers , the use of foreign technology , talent and a wealth of experience in wind power development , through international cooperation, to improve their level . Shi Pengfei , not without emotion, said .

China is the international wind power base

According to the World Wind Energy Association (WWEA) the statistical results , in 2012 the world's new wind power capacity 44GW, China is still a cumulative installed capacity of wind power accounted for 27% of global market share continues to remain the world leader position. World's wind power installed capacity of five countries were China , the United States , Germany, Spain and India.

In China , the world's largest wind power market, the lack of foreign fans never impossible corporate presence. Shi Pengfei, in an interview with reporters , said China's wind power industry in rapid development stage , foreign companies have been the Chinese wind turbine power construction participants. Ten years ago there were only two fan-made brands, the market most of the foreign brands, but now the situation is completely reversed . Even so, like Vestas in the Chinese market each year there are 500,000 kilowatts of the market.

He also pointed out that , in addition to the machine outside , foreign brands of parts or has an absolute advantage. The key components of the fan bearing manufacturer FAG, KF accounted for half of the domestic market , although the domestic bearing manufacturers have been trying , but the domestic wind turbine manufacturers mainly using imported bearings. Others, like converters, control systems and other key components or foreign brands in the market. Also on the advice of wind power , many of the domestic machine factory products are jointly designed and GL . In the wind power plant design software software, our fans are still dependent on foreign enterprises enterprises .

Accelerate the master core technologies to improve competitiveness

On China's wind power industry , the main advantage of the broad market does not exist for a long form , and also appeared at this stage installed capacity decreased gradually . This should focus on high value-added product development, differentiation strategy to promote wind turbine industry development , the realization of China in the global industry value chain to enhance the status . With the economic level and consumption levels increase , with new technology features high-value products will have more wind power vast international market.

Meanwhile, the international implementation and accelerate the pace of the wind power industry to re- scale pull back the economic sphere, once the wind power manufacturers mastered the core technology and products , it may become the industry leader. In the industrial development process , excessive competition in the market will not have the phasing out a large number of backward enterprises a competitive advantage in the industry, the process of integration of acquisitions , the whole industry will tend to focus on those core technologies with independent intellectual property rights and business, will by virtue of the key aspects of the control and monopoly of the core technology to become the industry leader , they will cooperate with each other to form a competitive industry, the integration of wind power , this integration will help our fans exports.

Homogeneity is also China's wind power products is a major drawback , to enhance international competitiveness, we need to implement strategies to differentiate from low-cost strategy to shift the corporate strategy focuses on product design, technical innovation, product improvement and service innovation, up , to create their own special and personalized products . At the same time , but also to avoid redundant investment and construction , and guide enterprises to gather resources to enhance the original , integrated innovation and re-innovation absorption capacity , extend the industrial chain , on this basis, to expand the scale of production , strengthen national brand building.

Slip ring slip ring is still the main force of low-cost

As the name suggests is used to electrically conductive slip ring slip ring slip ring series in all the most widely used , also known as brushless slip ring , carbon brushes, slip ring, slip ring , slip ring , rotary pass, rotating electrical joints, dedicated to the unlimited continuous rotation , the transmission power of power, signal power .

The choice of the motor brush commutation sparks have an important role in inhibition , should be power, voltage , load characteristics and the selection conditions such as the peripheral speed commutator . Commonly used electric graphite brushes , because resistance coefficient and contact voltage higher, suppression spark favor. But for low-voltage motors , the excessive contact voltage to make it in the proportion of the total voltage drop is too large, so the use of metal graphite brushes .

Since the majority of structural defects brush , so researchers developed a second generation of electricity on the Capsule Slip Rings , slip ring to avoid the kind of brush structure of many shortcomings, such as easy to wear , not oxidation . As modern technology advances, brush slip ring technology has become increasingly sophisticated , just before the use of copper and copper ring brush contacts for signal and current transmission, relatively soft due to copper , rotation speed or when the use of time after a long , easily deformed , affecting close contact , thus resulting in distortion of current and signal transmission . Behind the development of precious metal brushes and copper rings to solve this problem , such as adding trace elements of the alloy conductive materials, rare earth metals, rare metals , etc., a good solution to this problem . Now, brush slip ring slip ring is still the main force of cost . Many large amount of manufacturers, both in the use of cost-effective electrical slip ring , especially equipment price is not high, the number of very large companies , due to cost reasons, brush slip ring is still their first choice.

Machinery and equipment industry is the subject of financing concerns

October 16th , margin trading market amounted to 310.194 billion yuan , an increase of just over 130 million yuan the previous trading day , mainly due to lower financing to buy the market contraction , repayment growth , thereby promoting the net purchase amount shrank to 360 million million, while the previous value of 30 billion yuan this hovering . Is worth noting that the 16th financing the purchase amount rapid growth of the industry, in addition to previous concern information services , pharmaceutical and biotech industries , more than just the subject of financing the balance of machinery and equipment industry is also growing faster, access to financing concerns .
In fact, before the National Day two financial market showing the status of capital outflow , the net purchase amount in September the last two trading days are negative , but the net purchase amount of structured finance rapid rebound , the first trading day after the holiday recovered to 5.742 billion yuan , then dropped around 3 billion yuan fluctuate until the 15th . However, on the 16th so cautious market sentiment fell sharply again cautious.
The 16th largest sector financing outflow in the financial industry . According to Wind data show that the 16th financial sector financing net buying of $ -2.95 billion, this figure is lower than all other sectors , sports and entertainment , followed by financing net purchases amounted to -1.04 million. Financing net purchase amount among the top industries of manufacturing , information transmission , software and IT services sector financing net purchases amounted to 430 million yuan and 181 million yuan ; comprehensive , wholesale and retail , leasing and commercial non-property , agriculture, forestry , animal husbandry and fishery showed a net purchase financing conditions , other sectors showed a net repayment of state financing .
However, the rapid growth in financing the balance of the first 100 targets in pharmaceutical biotechnology , information services and machinery industry stocks were 14, 13 and 12 , of which machinery and equipment industries have sprung up everywhere , worthy of investor attention . Among them, Valin Singapore, Malaysia , Wolong Electric , EGing photoelectric financing balance both sequential growth of 23 % or more. Inner Mongolia, the king is to finance the balance of the previous trading day up 4.9 times , eye-catching performance .
