Abstract: To aim at the hidden peril of burning a washing machine in particular service conditions, forceful electric parts should pass the stringent safety standard according to Whirlpool- Global standard. Referred to the method of anti-pollution flashover by the power companies, we applied the RTV silica gel to the surface of the forceful electric parts. The result showed that after applying the RTV silica gel, the parts in particular service conditions were prevented to burn because of the flashover. Meanwhile, we discussed the positive role of the cryogenic plasma in improving the adhesive force between the RTV silica gel and the surface of the parts.

Key words: Washing machines, Arc resistance, RTV silica gel, Cryogenic plasma
