According to the Shanghai Securities News, Gamesa, one of the top five wind power companies in the world, announced in Shanghai that in the next three years, the company will double its investment in China to 130 million euros.
Gomez is the world leader in the design, production, installation and maintenance of turbines. It has a history of over 15 years and has more than 20,000 megawatts of installed capacity in 20 countries and regions on four continents.
China is the largest production base for Gemei Co. outside of Spain. The company currently has four factories in Tianjin and is building two new factories, respectively in Jilin and Inner Mongolia. After the two new plants are put into use, Gemeike's annual production capacity in China will increase to 1,500 megawatts. As of June this year, the total installed capacity of Gamesa in China is 2,675 MW.
Caffert said that the company will strive to achieve sales of the Chinese market to account for more than 30% of the company’s total global sales by 2012. The Chinese market’s contribution to Gomecom will double by 2011, ie sales of 800 to 1,000 megawatts. .
Caffert pointed out that China is one of the fastest growing regions in the global wind power market and the largest wind power market in the world. In 2009, China's wind power capacity doubled to 13.7 GW.
Recently, Gemeiyi has also signed new strategic agreements with two large Chinese power companies, China Guangdong Nuclear Power Wind Power Co., Ltd. and Datang Renewable Energy. According to the agreement, before 2014, Gamesa will use its new high-power turbines to develop and supply 1315.3 MW of electricity.
Coincidentally, another large-scale foreign-invested wind power company has also increased its attention to China in recent days. Tandi, the head of Suzlon Energy, a manufacturer of wind turbines in India, said this week that China’s market share for Suzlon’s overall business will reach about one-third by 2015, driven by China’s promotion of clean energy policies. The 10% increase significantly.
Commonly used LEDs are divided into four types: in-line LED, TOPLED, piranha and high-power.
1) In-line LED:
The electrical connection is in the form of 2-pin in-line, which is a traditional low-end product. Because the package has a large thermal resistance and the chip is not easy to dissipate heat, the light effect decays quickly and the life is short. The advantage is that it is cheap and can be made into a small light-emitting angle.
2) TOPLED:
The electrical connection is in the form of 2, 4 or 6-pin patch, which is currently a commonly used light source. According to the size of the package shape, it is divided into 0805, 1206, 3528, 3535, 5050, 5060 and other specifications. The larger the package shape, the better the heat dissipation performance, the correspondingly larger the bearable power, and the more light output.
3) Piranha:
It is a 4-pin in-line package. The heat dissipation performance and reliability are better than ordinary 2-pin in-line package. It can withstand 50~70mA working current. It is a commonly used light source at present.
4) High-power LED:
LEDs designed and produced with large-size chips and enhanced hot channel technology are usually divided into specifications such as 0.5W\1W\3W\5W. A single 1WLED can withstand a working current of more than 300mA and output a luminous flux of more than 100 lumens. It is widely used In civil commercial lighting, traffic control, photography, night vision and other fields. The price of high-power LED is still relatively high. With the gradual maturity of the technology, it will hopefully replace the traditional lighting source completely and lead the world into an era of solid-state light source.
