Introduction<br />
<strong>Von</strong> <strong>Roll</strong> is strongly committed to developing materials and processes used in<br />
insulating state-of-the-art electrical high-voltage motors as well as small generators<br />
with equivalent design. We are aware of our customers’ continuously increasing<br />
demand for higher performance and reliability together with low manufacturing<br />
costs.<br />
<strong>Von</strong> <strong>Roll</strong> provides a wide range of process equipment and materials to fi t the<br />
exact requirements of high-voltage motors using both resin-rich (RR) or vacuum<br />
pressure impregnation (<strong>VPI</strong>) technologies.<br />
Insulation materials for high voltage motors<br />
Many different materials are used in constructing a high-voltage coil or bar:<br />
WINDING WIRE (A)<br />
CONDUCTOR INSULATION (B)<br />
STACK CONSOLIDATION (C)<br />
MAIN WALL INSULATION : MICA TAPE (D) + <strong>VPI</strong> RESIN (H)<br />
CONDUCTIVE PAINT OR TAPE (F)<br />
STRESS GRADING PAINT OR TAPE (F)<br />
FINISHING OR SEALING TAPES (E)<br />
BRACING MATERIALS (G)<br />
SLOT WEDGING MATERIALS (I)<br />
Customers enjoy the following advantages:<br />
• Single source for all components<br />
• Proven compatibility for system components<br />
• Testing at <strong>Von</strong> <strong>Roll</strong> for both components and systems<br />
• Single source for technical support<br />
In this document we propose a variety of insulating materials and process<br />
equipment for large generators. The selection is by no means exhaustive. Please<br />
do not hesitate to contact our technicians for further details.
