A compact electrical bushing has a separate insulating end cap removably attached to the shaft of the bushing at an end used for mounting a current transformer. The removably attached insulating end cap has a large outer diameter that increases the linear surface distance of the bushing. The outer diameter may be determined in a predefined manner based on the desired length of the shaft, and vice versa, with a larger outer diameter corresponding to a shorter shaft. The increased linear surface distance allows the bushing to meet minimum tracking distance with a shorter shaft relative to existing bushings. The shorter shaft reduces the footprint of switchgear and other electrical isolation equipment to which the bushing may be connected. The insulating end cap may be removed from the bushing as needed to allow the current transformer to be slid onto the bushing without having to pass over the end cap.
