The contamination deposition characteristics of insulators can be used in the development of antifouling work. Using COMSOL software. numerical simulations on the pollution-deposited performance of a porcelain three-umbrella insulator and porcelain bell jar insulator in a wind tunnel were conducted. and the simulated results were compared with the tested results. https://parisnaturalfoodes.shop/product-category/shampoo-unscented/
