China's first 500 kV EHV cable line has been put into operation

By Ministry of science and technology as "China's first 500 thousand volt 2005 National Torch Project" EHV cable line in Shandong at the end of October, Yanggu Cable Group Co., Ltd. officially put into operation, not only to fill the domestic blank and replace the imported products, marking China's dependence on foreign imports of such products in the history of the end.

In recent years, China's demand for ultra high voltage XLPE cable to 500 thousand volts soaring, especially the development of Western China in the development of hydropower resources, most hydropower station and pumped storage power station and in the construction of the Qiongzhou Strait ultra high voltage submarine power cable line, are required to use this cable, but the country had no a kind of cable production line.

Yanggu cable group, which was built in 1985, is a small factory with more than 20 people, which is responsible for the construction of 500 thousand kV EHV XLPE cable project. After 20 years of hard work, has developed into a technologically advanced, well-equipped, strong country specializing in the production of wire and cable large group of companies.

The project was launched in 2004, a total investment of 175 million yuan, from Finland and the United States were the introduction of cross-linked power cable lines and resonant test equipment today has the world leading level and 3000 ton aluminum pressure machine, and the construction of a vertical cross tower 128.9 meters high.

The Group R & D Department of a responsible person said, we go is the introduction of technology and independent research and development of the road of combining, in the absorption of foreign advanced technology at the same time pay more attention to the use of scientific research personnel of innovation ability, the operation of the EHV cable line, many of the core components is our independent research and development achievements.

At present, the company's products of wire and cable has 7 categories of 800 kinds of models of 21 thousand varieties, annual production capacity of more than 20 yuan, the companies were rated as the core competitiveness of China machinery industry top 100 enterprises.
