17.05.2005 - NEW DEVELOPMENT: High-Current Transformer with Collapsible Core

For conductor heating equipments with a length of 10 to 100 m and with a conductor
diameter of approx. 250 mm RUHSTRAT has developed collapsible cores on the basis of
limb cores as movable construction. These high-current transformers are used for the
thermal verifications of high-tension cables. The upper cover of the high-current transformers
can be opened thereby which makes an easy and uncomplicated change of the cables
possible. The motor-driven opening and closing of the cover is carried out via push buttons
on the manual control unit.
