COMBINED TERMINATION FOR USE OUTSIDE OF PREMISE FOR HIGH-VOLTAGE CABLE Russian patent published in 2010 - IPC H01B17/62 

FIELD: electricity.

SUBSTANCE: termination for use outside of premises reduced impact of environment and electric voltages due to combination of the first part, second part and large number of skirts in the form of undetachable insulation solid. The first part includes combined first connector for connection of termination designed for use outside of premises to high-voltage cable. The second part functions as cone of voltages and connects to the second output for connection to ground. The first part has, in general, cylindrical shape, and cone of voltages has, in general, conical shape. The first part changes into the second part without any sharp changes in area of cross section, making it possible to avoid increase of electric fields. Combined termination for use outside of premises may be manufactured previously with application of such material as silicon. Skirts pass approximately perpendicularly to longitudinal axis of insulation solid and may be evenly distributed along this axis. Even distribution of skirts makes it possible to prevent breakthrough.

EFFECT: reduced leakages of current and chances of surface breakthrough since insulation solid is arranged as a single piece.
