Highly flexible cable with flex resistance for wind power generation

technical field

The utility model relates to a flexure-resistant high-flexibility cable for wind power generation, which belongs to the technical field of cables.

Background technique

In order to speed up the development of wind power in my country, according to the current situation of wind power development in my country and drawing on the experience of foreign wind power development, the National Development and Reform Commission formulated the "Wind Power Medium and Long-term Development Plan". By the end of 2010, the total installed capacity of wind power in the country will reach 4 million kW; by the end of 2015, the total installed capacity of wind power in the country will reach 10 million kW; and by the end of 2020, the total installed capacity of wind power in the country will reach 20 million kW. The large-scale development of wind power has further improved various technical and economic indicators, and the competitiveness and profitability of wind power enterprises have been significantly enhanced. After 2020, fossil fuel resources will decrease, thermal power costs will increase, and wind power will have market competitiveness and develop faster. After 2030, most of the hydropower resources will be developed, and offshore wind power will enter a period of large-scale development, which may form a situation of "power transmission from east to west". The construction of wind power stations will also enter a golden period. Due to the particularity of the cable requirements of wind power generating units, for harsh environments such as deserts, coastal alpine, strong ultraviolet radiation, seaside salt spray, salt water, etc., cables for wind power plants are required to have high tensile strength, high conductivity, high and low temperature resistance, and high temperature resistance.
