Title: INSULATION ARRANGEMENT FOR A HIGH OR MEDIUM VOLTAGE ASSEMBLY
Abstract:
The invention relates to an insulation arrangement for a high or medium voltage switchgear assembly, comprising at least one axially symmetrical insulating structural element (2). The invention is distinguished by the fact that the structural element (2) has at least two annular base areas (4), which are separated from each other by an annular blocking area (6), wherein the relative permittivity of the material of the blocking area (6) is at least twice as high as the relative permitticity of the material of the base area.
