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). It is characterized in that the spacer (4) has a multitude of holes (9) that are fillable with the matrix material (6). Preferably, the spacer (4) is net-shaped or meshed. It can be a net of fibers. The bushing (1) can be a fine-graded bushing (1) with equalizing plates (5) within the core. As a matrix material (6), a particle-filled resin (6) can be used.

摘要： A bushing with a duct (6) for accommodating a conductor rod which is surrounded by an electrical field grading insulation (5) comprises a core (1) with a cylindrical shell (2) encapsulating the grading insulation (5) and a f lange (3) surrounding the said shell (2) and carrying through holes (8) distributed over its circumference for allowing the bushing to be attached to a wall (4) by bolts (12). The shell (2) and the flange (3) are in one piece and consist of an insulating matrix material, e.g., a plastic material mixed with an anorganic filier material. The through holes (8) are surrounded by essentially ring-shaped metal inserts (9) each forming an annular surface flush with the surface of the flange (3) which is in contact with the head of the bolt (12) and takes up the force exerted by the latter on the flange (3). A test tap (13) comprises a contact pin (14) which is electrically conductively connected to the outermost layer of the grading insulation (5) and surrounded by a contact ring (15) connected to every second metal insert (9) by connection wires (17) for grounding the contact pin (14) via the contact ring (15) when the test tap (13) is not in use and covered by a metal cap. The core (1) is produced by filling a mould with the liquid matrix material after components of the grading insulation (5) and other parts have been fixed in the same.
