摘要:
It is presented a bushing (1) comprising a condenser core (3) arranged to house an electrical conductor (15) along a central axis (X) of the condenser core (3), wherein the condenser core (3) has a tapering end portion (3-2a) arranged to be in contact with a fluid dielectric having higher dielectric withstand strength than air, the tapering end portion (3-2a) presenting a surface having a first portion (4-1) with a first inclination (I-1) in the axial direction and a second portion (4-2) with a second inclination (I-2) in the axial direction, which second inclination (I-2) differs from the first inclination (I-1), wherein the first portion (4-1) and the second portion (4-2) define planes that intersect the central axis (X). A system comprising such a bushing is also presented herein.
摘要:
According to the invention is defined an electric insulation material (1) for an electric device comprising one or several electrical conductors and an electric insulation material arranged around the conductor or between the conductors, and which insulation material is impregnated with a dielectric insulation liquid. The electric insulation material comprises a main layer (2) that is provided with a surface layer (3) that has a dielectric constant that is lower than the dielectric constant of the main layer.
