WIPO Patent Application WO/2023/248517
Kind Code:
A1
Abstract:
The present invention provides a composite material, which comprises an insulating spacer that demonstrates at least the conventional, or higher, creepage withstand voltage even in AC equipment in atmosphere, and which enables size reduction in high-voltage devices while having improved insulation reliability. A composite member according to the present invention comprises a first conductor, a second conductor spaced apart from the first conductor by a predetermined distance and having an electric potential different from that of the first conductor, and an insulating spacer supporting the first conductor and the second conductor. The insulating spacer is characterized by having irregularities formed between the first conductor and the second conductor, the irregularities having a length that is 1/100 times or more a length corresponding to the creepage distance of the insulating spacer.
