A method and system for a combination insulator cover configured to fit a plurality of insulator cable clamp devices are provided. The cover includes a dome configured to receive an insulator top and a plurality of cable cavities that extend orthogonally away from the dome in opposite directions. The plurality of cable cavities are configured to permit passage of a cable therethrough, the cable cavities include a first cylindrically shaped portion and a second cylindrically-shaped portion, first cylindrically shaped portion being larger than a diameter of second cylindrically-shaped portion. The cover also includes a lower extension that extends along a bottom edge of said cover from a distal end of said second cylindrically-shaped portion to a distal end of the opposite second cylindrically-shaped portion, said lower extension is split parallel to the plurality of cable cavities.
