Vacuum-Epoxy-System For Cast-Resin Transformers
|
 |
In spite of the use of abrasive fillers, this system operates with a high level of availability and requires virtually no maintenance. The cast-resin transformers are cast fully automatically first under vacuum and then under pressure, the complete process being microprocessor-controlled. The system uses a preformulated multi-component resin with quartz powder as filler. Ceramic metering pumps able to stand up to the abrasive filler are driven by synchronously running brushless servomotors.
Electronic online control of the metering as well as of the overall process for constant casting quality. High performance degassing units for optimum degassing with materials of all viscosities for both continuous and discontinuous processes.

Demands to be met by the cast part:
|
•
•
•
|
High mechanical strength and fracture toughness at - 269 °C.
Three chambers for casting under vacuum followed by application of pressure.
Each mould group loaded into the casting chamber can be identified by barcode |

Discharge-free, resistant to surge voltages and compact
The casting of cast-resin-transformers requires highest mixing accuracy and absolute precision at metering, while the metering pumps have to be strongly resistant against abrasive filling materials. Furthermore, the process has to be environmentally friendly and saving resources.
