When dimensioning, it should be noted that the maximum achievable impregnation widths r of the impregnation holes L are smaller than the impregnation widths A. which are reached from the end faces S, S ''of the capacitor winding. While the impregnation path A from the end face into the winding is, for example, 30 mm, the impregnation width r is only 25 mm with an impregnation

The FRAKO LKI capacitor, for instance, contains an impregnation agent with an exceptionally high flash point of more than 250 °C. When compared with other impregnation agents, e.g. those in older power capacitors containing a mineral oil with a flash point of roughly 130 °C, this impregnation agent can be considered non-inflammable.
