PoSeCo: Alternative to metallized core shielding

PoSeCo, abbreviation for Polyglas® Semi Conductor, is a conductive Polyglas® tape that revolutionizes the way in which transformer cores are shielded and protected. It is made of Polyglas® and was developed to replace both the metallized core shielding and the mechanical fixing straps around the core columns.
