Abstract
In a cost-effective and qualitatively better method for producing spacers for a winding unit of an electrical high-voltage device, at least two starting components are mixed together in a mixing chamber under vacuum to form a component mixture. The component mixture is transferred to an extrusion housing, likewise under vacuum, of an extruder in which a transport device is arranged and which is equipped with a mouthpiece delimiting an outlet opening. The extrudate exiting from the mouthpiece is cured by the addition of heat in a vacuum in order to obtain the spacers.
Claims6
A method for producing spacers for a winding unit of an electrical high-voltage device, which comprises the steps of:
- mixing at least two starting components together in a mixing chamber under a vacuum to form a component mixture;
- transferring the component mixture to an extrusion housing of an extruder likewise being under vacuum, and in the extruder a transport means is disposed and equipped with a mouthpiece delimiting an outlet opening;
- and
- curing extrudate exiting from the mouthpiece by an application of heat in a vacuum, in order to obtain the spacers.
