This study introduces a durable armored superhydrophobic ceramic surface for outdoor insulators. It offers superior weather resistance and pollution flashover voltage, enhancing power grid stability.
Area of Science:
- Materials Science
- Electrical Engineering
- Surface Chemistry
Background:
- Outdoor insulators face pollution flashover due to contamination and water films.
- Traditional superhydrophobic coatings lack durability against environmental aging.
Purpose of the Study:
- To develop a robust superhydrophobic ceramic surface for outdoor insulators.
- To enhance weather resistance and pollution flashover performance.
Main Methods:
- Fabrication of an armored superhydrophobic ceramic surface using inorganic sintering.
- Evaluation of weather resistance (water impact, UV, condensation, salt spray, chemical corrosion).
- Assessment of pollution flashover voltage compared to conventional materials.
Main Results:
- The armored surface maintained superhydrophobicity after 3000 hours of UV exposure.
- Exceptional resistance to various environmental stressors was demonstrated.
- Pollution flashover voltage exceeded RTV silicone rubber and bare ceramic by 70% and 148% respectively.
Conclusions:
- The armored superhydrophobic ceramic surface offers superior durability and performance for outdoor insulators.
- This innovation has potential for improving power grid stability by mitigating flashover risks.
