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.

Gas insulator switchgear

A high-voltage circuit breaker has an interrupter unit, a closing resistor and a switch which is connected in series with the closing resistor. The interrupter unit has a driven first interrupter contact which can move along an axis and interacts with a second interrupter contact, which is arranged on the axis in order to open and close the high-voltage circuit breaker. The switch has a switching contact which can rotate about a rotation shaft (D) and whose rotary movement is coupled by of a link control to the movement along the axis (A) of the first interrupter contact.
