Abstract
The method is provided for manufacturing a perforated sheet-like high-voltage insulating spacer for a high-voltage component, which component comprises a field grading condenser core with the spacer which is wound in spiral form around an axis, with electrically conducting layers which are inserted between successive windings of the spacer, and with a polymeric matrix which penetrates the spacer and which embeds the spacer and the layers. The method comprises at least steps as follows: an electrically insulating tape, and the patterned tape is expanded at right angle to the cutting lines in order to form a spacer with a perforated three-dimensional lattice structure. The combined effect of cutting a tape and expanding the cutted tape allows the formation of spacers with a manifold of sizes which exceed the size of the tape in function of manufacturing parameters, in particular in function of the configuration of the pattern and the magnitude of the expansion.
