A cold shrink protective cover for a cable junction including a first cable having a first outer diameter and a second cable having a connection to the first cable. The second cable has an outer diameter that differs from the outer diameter of the first cable. When shrunk around a cable junction the protective cover comprises a first shrinkable tubular member, covering a portion of the first cable and a portion of the connection, and a at least a second shrinkable tubular member covering a portion of the second cable and extending over the connection to at least partially cover an end portion of the first shrinkable tubular member to form an overlapped seam between the two tubular members.
