Product description

Fixed dimensions for high performance: 096 series represent a simple but extremely incisive solution for distribution transformers with reduced power. Modular design make this tap changer unique: shaft is available in two different lengths – 91 mm or 131 mm; contacts are available in different versions: threaded or tubular with different diameters, according to the rated current; moreover, in case of current from 150 A to 200 A, removable contacts are available as well.
Drive is always padlockable for better safety and precision and is made of aluminum, with specific treatment in case of certain environmental conditions. It can be provided with special gaskets for lower or higher temperatures; with anti-corrosive treatment for off-shore applications.
All 096-series tap changers have a solid innerwing made of aluminum casting and a special shaft structure that allows direct insert into the related tank hole. No stuffing box needs to be welded to the transformer tank – the installation process is very easy!
