Cable, and method for removing sheath at intermediate part of cable

A cable having a supporting wire and a cable core each covered with a plastic sheath, the plastic sheaths being connected intermittently in the longitudinal direction of the cable by plastic constituting neck parts, wherein tension members are embedded in the longitudinal direction in the sheath resin of the side of the plastic sheath covering the cable core nearest the supporting wire and of the side farthest from the supporting wire, grooves are provided extending in the cable longitudinal direction in the inner surface of such plastic sheath in two locations set apart by a predetermined angle in the circumferential direction from the positions of the tension members in such plastic sheath, ripcords are fitted in the grooves, and a position indicating means showing the positions of the ripcords are provided on the outer surface of the plastic sheath at the points where the rip cords are fitted.

A cable having a plastic sheath provided around the outer periphery of a cable core, wherein a ripcord extending in the longitudinal direction of the cable is adhered to the inner surface of the plastic sheath and a position-indicating means showing the position of the ripcord is provided on the outer surface of the plastic sheath at the point where the ripcord is adhered.

A method for stripping an intermediate part of a cable, wherein, using a cable having a plastic sheath provided around the outer periphery of a cable core and a ripcord extending in the longitudinal direction of the cable disposed on the inner surface of the plastic sheath and a position-indicating means showing the position of the ripcord provided on the outer surface of the plastic sheath at the point where the ripcord is disposed, after the cable is installed, at any position on the intermediate part of the cable, a part of the plastic sheath is shaved off with the position-indicating means as a guide and a part of the ripcord is exposed and then by pulling the ripcord in a direction in which the plastic sheath is to be split the plastic sheath is split in the longitudinal direction of the cable and the split part of the plastic sheath is then severed to expose the cable core.
