It features two pairs of adjustment taps, i.e. 2 x 2.5%, to optimally adjust the local network voltage to the transformer. Its insulation capacity is 125kV. It is coupled in Dyn11 configuration. As standard, this product complies with the latest European Ecodesign directive, meaning it has reduced no-load and load losses.
