Beschreibung
|
|
Three-phase transformers, built as isolating transformers conform to EN 60076, prepared for protection index I.
Basically this type size can be built in any vector group. If there is no vector group given, we will use Dyn11 by default (star point fully loadable with outer conductor voltage).
Please consider the difference between outside conductor voltage and phase voltage to star point at the different vector groups.
For a safe and easy transport, the transformers have crane hooks at the upper side. The mounting has to be done in a way, that makes natural cooling through the cooling channels possible.
Tauscher cast resin transformers don’t require a lot of space, compared to oil transformers. They work maintenance free, not easily flammable and self-extinguishing. The isolation of the windings is done with environmental-friendly polyurethane- or epoxy cast resin.
