Problems solved by technology

In particular, conventional composite insulator sheds have weak hydrophobicity, and their hydrophobicity rapidly decreases or even loses after operating in heavily polluted areas. The performance is lower than the electrical performance of ceramic insulators and tempered glass insulators of the same size, which seriously endangers the operation safety of the power grid system
[0004] Under outdoor operating conditions, the surface pollution of ceramic insulators and tempered glass insulators can be removed to a certain extent by rainwater and strong winds, while conventional composite insulators are weakly hydrophobic and prone to electrostatic adsorption on the surface, showing different material pollution Due to the difference in coefficients, the pollution is serious in a dir

Description

technical field [0001] The invention belongs to the field of composite insulators, and in particular relates to a super-hydrophobic self-cleaning material, a production method thereof and a composite insulator produced with the material. Background technique [0002] Composite insulators have been in trial operation in my country's power grid for nearly 30 years, and have been used in large quantities for more than 15 years. Composite insulators have formed an application situation that exceeds half of the amount of ceramic insulators or tempered glass insulators in the power grid. Power grid system equipment is often exposed to different pollution conditions during long-term operation, and the operating environment is very harsh. While providing the necessary internal and external insulation, composite insulators have the advantage over traditional ceramic insulators or tempered glass insulators that they are hydrophobic, which enables composite insulators operating under d...
