Sound-absorbing sandwich-like composite metal sheet for installation between core of oil-cooled transformer and transformer kettle walls, has plastic layer designed as shield against electromagnetic scattering fields in inner side of kettle

摘要

The metal sheet has two outer metal sheet parts made of metal. A plastic layer is made of viscoelastic plastic and located between the metal sheet parts. The plastic layer is designed as a shield against electromagnetic scattering fields in an inner side of an oil-filled transformer kettle made of metal. The plastic layer partially covers the transformer kettle walls, where the metal sheet is fastened at transformer kettle walls in a force-fit manner.
