Claim:
A high voltage loadbreak bushing insert including an insulative housing having an axial bore therethrough and a conductive member disposed within said axial bore, wherein said insulative housing comprises: a first end section being dimensioned to be seated in a bushing well, a second end section opposite said first end section, said second end section being dimensioned for insertion into a power cable elbow connector; and a mid-section disposed between said first and second end sections, said mid-section being radially larger than said first and second end sections and being dimensioned to be sealed against an elbow cuff of the power cable elbow connector; and a transition shoulder portion disposed between said second end section and said mid-section, said transition shoulder portion including at least one raised venting portion protruding radially outwardly from said transition shoulder portion, said raised venting portion being adapted to force the elbow cuff of the power cable elbow connector to expand in a radially outward direction upon withdrawal of said second end section from said power cable elbow connector, thereby venting a cavity formed between said bushing insert and the power cable elbow connector.
