Latest Patents

Polander's latest patents include a high voltage insulation system and a method of manufacturing the same. This innovative system features a bushing, a conductor, a transformer conductor, and a connection between the conductor and the transformer conductor. A conductive shielding electrode is designed to shield the connection between the bushing and transformer. The surrounding insulation system is immersed in transformer oil and comprises transformer insulation material and bushing insulation material. Additionally, a cylindrical solid insulation barrier encloses the connection between the bushing conductor and transformer conductor. At least one solid insulation barrier is fastened on the outer side of the shielding electrode, extending in an axial direction outside the axial direction of the shielding electrode. This design creates a distance to the insulation material of the bushing and the insulation material of the transformer, resulting in a moderate voltage drop over the solid insulation barrier.

Another significant patent is for a high voltage transformer with a shield ring. This transformer includes a housing that contains internal components submerged in transformer oil, equipped with insulation for a high voltage winding end. The insulation features a shield ring arranged above the winding end and a pressboard structure formed in a zigzag pattern around the winding end. The shield ring consists of a core covered with a conducting layer and a continuous solid insulation layer outside the conducting layer. The insulation layer incorporates integrated solid insulation sections, some of which have varying thicknesses.
