VOLTAGE-RESISTANT, ELECTRICALLY INSULATING COATINGS

摘要

The invention relates to a device (10), wherein the surface (11) thereof is provided with an electrically insulating coating (12) which is voltage-resistant to at least 1000 volt. Said device is characterized in that the coating (12) comprises multiple layers, namely at least one lower layer (14) having a thickness (16) of at most 50 µm, and an upper layer (15) having a thickness (17) of at most 50 µm, wherein the lower layer (14) is made of a hard voltage-resistant material and the upper layer (15) from a voltage-resistant material which is able to penetrate interstices (fig. 1 ).
