Patent ID: 7648376

Claim:
A loadbreak connector with increased flashover distance comprising: a power cable elbow comprising: a cable receiving end; a loadbreak bushing insert receiving end having an open end portion; a conductive member extending from the cable receiving end to the bushing insert receiving end, wherein the conductive member includes an energized portion and a non-energized portion at the bushing insert receiving end; and an elbow cuff circumferentially disposed around the open end portion and extending beyond the energized portion of the conductive member; and a bushing insert comprising: an insulative outer housing having an axial bore therethrough, a first end section dimensioned for sealing in a bushing well, a second end section dimensioned for insertion into the power cable elbow, a mid-section that is radially larger than the first and second end sections and having a conductive portion for attachment of a ground conductor, and a transition shoulder portion between the second end section and the mid-section; a conductive socket disposed within the axial bore of the housing; and an insulative interface sleeve extending over the outer housing from the mid-section to the second end section, wherein, when the power cable elbow is installed on the second end section, the flashover distance from the top of the second end section to the bottom of the elbow cuff is increased.
