Introducing HI Vax. This system is widely used in the transport industry for traction motors for trains. We also manufacture coils for any machine requiring VPI varnishing, however on larger machines we recommend you use the Hi Brid system's guaranteed slot fill.

What Hi Vax offers
One of VPI technology's virtues is its ability to work at higher ambient temperatures if a silicone-based resin is used for impregnation. Resin rich technology hits a temperature plateaux at Class F, or 180°C, where as VPI technology has the ability to go up to a working Class C, or 220°C. This makes it ideal for AC traction windings and all machines working at high temperatures.

For tight lead times VPI offers an interesting solution as there are no pressing times to slow production.
