The invention discloses a cable identification sheath. The cable identification sheath comprises a cable cutting sleeve and a cable sheath, wherein the cable cutting sleeve can be tightly clamped outside the cable sheath; the cable sheath is an elastic casing; the cable sheath is in a combined color of two or more colors in order to distinguish different cable sheaths or cables; clamping buckles are arranged at two ends of the cable cutting sleeve; and vertical cable identification plates are fixed to the cable cutting sleeve. The cable sheath is relatively long, and coats a cable. With a bright color, the cable sheath is easy to distinguish and check, and can be recognized conveniently and rapidly. The cable cutting sleeve is convenient to detach. Detailed information of the cable can be identified through the cable identification plate, so that maintenance personnel can conveniently check the cable in more detail.
