Appeal No. 1998-2981
Application No. 08/763,390
The invention relates to use of stress control means to
control electrical stress in a region of high electrical field
strength due to a shield discontinuity in high voltage cable
or electrical equipment, for example, electrical bushings, and
joints or terminations of high voltage cables. The present
invention includes an elastically recoverable elastomer
insulating sleeve which is provided with an inner support or
core. Between the sleeve and core is disposed a two part
stress control system consisting of a non-tacky, void-filling
conformable stress control material surrounded by an elastomer
stress control tube. In one embodiment, the conformable
stress control material is disposed in contact with the cut
end of the cable shield and extends along the cable
insulation. The conformable stress control material is also
in contact with the cut end of the cable insulation and lug.1
