A loadbreak connector formed by a power cable elbow and a bushing insert with increased flashover distance is disclosed. The power cable elbow includes a conductive member having an energized portion and a non-energized portion, a cable receiving end, a loadbreak bushing insert receiving end with an elbow cuff that extends beyond the energized portion. The bushing insert includes an insulative outer housing and an insulative interface sleeve. The insulative outer housing has an axial bore with a conductive socket, a first, second end mid-section, and a transition shoulder portion between the second end section and the mid-section. The insulative interface sleeve extends over the outer housing from the mid-section to the second end section. 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.
