Description

[0001] technical field [0002] The invention relates to the field of wire and cable manufacturing, in particular to an EPDM rubber used for manufacturing wind energy cables and a preparation method thereof. Background technique [0003] Wind energy is an inexhaustible and very clean energy, which contains huge energy, so the development of wind power in the world is rapid, and it is booming at a rate of doubling every year in China. The national plan for wind power generation is : It will reach 30 million kw by 2020, but judging from the current development speed, my country's installed capacity of wind power generation will far exceed the planned development plan of the country, and the development of wind power generation is in full swing, giving birth to a strong demand for wind power cables. [0004] Due to the harsh environment of wind energy cables all year round, and the large difference in wind levels in my country, the vast area, the large climate difference between...
