Abstract

An armored type electrical transformer comprising a magnetic core, a plurality of electrical coils defining at least one coil opening, and arranged in said coil opening at least one combined anti-worm magnetic screen, characterized said transformer by the fact of that said combined magnetic and anti-clock screen comprises: a plurality of separate bundles or bundles of magnetic sheets, each of said bundles of magnetic sheets subject to a rigid member; electrically conductive tubes placed between said groups of magnetic sheets and the sides of said coil opening; and an electrical conductor located between the bundles of magnetic sheets and the electric coils, and which bridges the bundles of separate magnetic sheets.
