摘要:
The high-voltage bushing (1) has a conductor (2) and a core (3) surrounding the conductor (2), wherein the core (3) comprises a sheet-like spacer(4), which spacer (4) is impregnated with an electrically insulating matrix material (6). The spacer (4) is wound in spiral form around an axis (A), the axis (A) being defined through the shape of the conductor (2). Thus, a multitude of neighbouring layers is formed. The core (3) further comprises equalization elements (5) in appropriate radial distances to the axis (A). It is characterized in that the equalization elements (5) comprise electrically conductive layers (51), which layers (51) have openings (9), through which openings (9) the matrix material (6) can penetrate, and in that the equalization elements (5) are applied to the core (3) separately from the spacer (4). Preferably, the electrically conductive layers (51) are net-shaped, grid-shaped, meshed or perforated. The openings (9) are fillable with the matrix material (6), preferably a particle-filled resin (6) can be used.
