Abstract
An exemplary high-voltage bushing has a conductor and a core surrounding the conductor, wherein the core includes a sheet-like spacer, which spacer is impregnated with an electrically insulating matrix material. The spacer can have a multitude of holes that are fillable with the matrix material. The spacer can be net-shaped or meshed. It can be a net of fibers. The bushing can be a fine-graded bushing with equalizing plates within the core. As a matrix material, a particle-filled resin can be used.
