Description

technical field

[0001] The invention relates to the technical field of coatings for safety protection, in particular to an insulating coating for high-voltage electrical appliances and a preparation method thereof. Background technique

[0002] At present, in some places where high-voltage electrical appliances are used, due to some subjective considerations and objective conditions (such as in order to save materials, reduce costs, etc.), the setting of some high-voltage electrical equipment does not meet the safety distance required by the standard, and its working environment is often polluted. It is more serious, so pollution flashover accidents often occur in electrical equipment, and there are also short-circuit and grounding accidents caused by accidents (such as small animals such as snakes and rats). The vicious cycle accidents of equipment and power outages have caused great losses and disasters to people's lives and production and construction.
