Reduction in a dielectric volume by using glass bubbles |
摘要 |
These glass bubbles obtained from a tube have a density determined by the variation in the thickness of the wall of the tube and they may be filled with a gas which is itself insulating. They are intended more particularly for containers (tanks) of transformers and for embedding coils. <IMAGE>
