ARMATURE FOR HIGH-VOLTAGE CABLE AND METHOD OF MANUFACTURING ARMATURE FOR HIGH-VOLTAGE CABLE Russian patent published in 2019 - IPC H02G15/02 

FIELD: valve production.

SUBSTANCE: high-voltage device for housing a high-voltage cable with a conductor made for conducting electric current and with cable insulation surrounding the conductor comprises an insulation and a waveguide. Insulation contains a portion of the field control made of a siloxane polymer, which is transparent or translucent in at least some areas and is made to at least partially surround the cable insulation of the high-voltage cable, the siloxane polymer in at least one portion of the field control portion contains covalently bonded fluorophores and/or dielectric pigments. Waveguide is positioned so that a light signal caused by a partial discharge in the field control part can be introduced from the field control part into the waveguide.

EFFECT: invention improves the reliability of detection of damage to insulation of high voltage equipment.
