Energie Block TEB
The EnergieBlock TEB transformer enclosure is a system for cast resin transformers for outdoor and indoor use. Transformers with a power rating of up to 1600 kVA and a rated voltage of up to 24 kV can be installed in this enclosure. The enclosure meets the requirements for AN and AF operation and can be equipped with a roof-mounted and cross-flow fan for AF operation. The EnergieBlock TEB can be combined with either the BasisBlock or VarioBlock systems.
