Electric angle steel tower
Electric angle steel tower is a kind of steel structure which can keep a certain safe distance between the supporting conductors and the ground buildings in the transmission line.
In recent years, with the rapid growth of national economy, the power industry has developed rapidly, which has promoted the rapid development of transmission line tower industry. According to statistics, the sales revenue of transmission line tower industry in China increased from 5 billion yuan in 2003 to 42.6 billion yuan in 2010, with a CAGR of 36.68%, and the industry is in a period of rapid development. In 2010, China's transmission line tower industry has a good development trend, and the enterprises in the industry have higher management and control ability of cost and cost, and have strong profitability.
By the end of 2010, 252 transmission line iron tower Enterprises above the scale in China had reached 32.250 billion yuan, an increase of 25.55% year on year. In 2010, the total industrial output value of China's iron tower industry was 43.310 billion yuan, an increase of 25.36% year-on-year; sales revenue was 42.291 billion yuan, an increase of 29.06% year-on-year; the total profit reached 2.045 billion yuan, an increase of 43.09% year-on-year.
During the 12th Five Year Plan period, China will increase the investment in power grid, with an investment of about 2.55 trillion yuan, accounting for 48% of the total investment in power, which is about 3.0% higher than that in the 11th Five Year Plan period. With the increasing investment in power grid, the demand for transmission line tower will also increase constantly, and the development prospect of transmission line tower industry is broad. The annual composite growth rate of sales revenue of China's transmission line tower industry is 28% from 2011 to 2012, and it is expected that the sales revenue of China's transmission line tower industry will reach RMB 70.3 billion.
