ELECTRIC TRANSFORMER COMPRISING AN INSULATING MATERIAL, AND METHOD FOR MANUFACTURING SUCH A TRANSFORMER

摘要

the electrical transformer (10) includes: a magnetic core (16), a first coil (6) wound around the magnetic core (16) and a receiving the input ac power input.a second winding (20) are wound around the magnetic core (16) and provides its output an alternating current output.a receiving space is defined between the first (22) and second (18) and (20) windings.and an insulating material (30) is cast within the space (22) for receiving the first winding electrically isolated (18) of the second winding (20).the insulating material (30) comprising a plurality of particles of alumina.it is characterized in that the insulating material (30) includes a silicon elastomer containing a plurality of particles of alumina.
