Abstract: A high-voltage device for receiving a high-voltage cable having a conductor designed to conduct an electrical current and a cable insulation surrounding the conductor, includes an insulation and a waveguide. The insulation includes an at least partly transparent or translucent field control unit from a siloxane polymer which is designed to at least partly surround the cable insulation of the high-voltage cable, the siloxane polymer including, in at least one portion of the field control unit, covalently bonded fluorophores and/or dielectric pigments. The waveguide is arranged such that a light signal caused by a partial discharge in the field control unit can be coupled from the field control unit into the waveguide.
