A device for simultaneously stripping at least two cable ends surrounded by insulation material includes a cutting device having first and second cutters that are movable relative to each other in a direction perpendicular to the longitudinal direction of the cable ends. The cutting edges of the first and second cutters are disposed substantially in the same plane and are movable towards each other such that the cutting edges simultaneously cut into the insulation material of the at least two cable ends. In addition, the cutting device and the cable ends are movable relative to each other in the longitudinal direction of the cable ends to simultaneously pull-off the cut insulation material from the at least two cable ends and thereby strip the at least two cable ends.

Techniques, systems and articles are described for preparing electrical cables for connections to a power grid. In one example, a system includes a cable preparation device configured to cut one or more layers of an electrical cable and a computing device configured to control the cable preparation device to cut the one or more layers of the electrical cable. The computing device may determine one or more target cutting distances and determine whether an actual cutting distance satisfies the target cutting distance. The computing device may detect defects in the electrical cable. The computing device may further determine whether the cable preparation device should be serviced.

The invention relates to a device (1) for stripping a clable (2), comprising a stripping apparatus (3) for cutting in and for pulling off a portion (4) of a cable component (13, 14, 15). The stripping apparatus (3) has a rotation head (5), which can be rotated about a central axis (M) and on which a blade (8, 8′) and a counter-holder (9) for the cable (2) are arranged opposite one another in such a way that the blade and the counter-holder are directed at the central art (M). The cable (2) is guided eking the central axis (M) in the stripping apparatus (3), and the blade (8, 8′) can be advanced toward the cable (2) in the direction toward the central axis (M) in order to produce a radial incision into cable component (13, 14, 15) of the cable (2) at a defined axial position. The stripping apparatus (3) has at least one pull-off tool (10.1, 10.2), which is arranged on the rotation head (5) and can advanced onto the cable (2) in the direction toward the central axis (M), the pull-off tool (10.1, 10.2) being positioned relative to the blade (8, 8′) in such a way that, in order to pull off the portion (4) of the cable component (13, 14, 15), the pull-off tool (10.1, 10.2) engages in the incision produced by the blade (8, 8′) when the pull-off tool (10.1, 10.2) is advanced onto the cable (2).

A cutting blade assembly for use with a rotating cable preparation device includes a cutting blade defining a cutting edge and adapted to attach to a rotating member of the cable preparation device. The cutting blade assembly is selectively movable in a cutting direction for at least partially cutting a cable held by the device. The assembly further comprises a blade stop positioned adjacent to the cutting edge of the blade and defining a stop surface. The stop surface is arranged at a predetermined distance from the cutting edge of the blade in a depth direction of the blade, and extends in a direction generally perpendicular to the cutting direction and generally parallel to an axis of the cable.

A cable preparation machine includes a frame forming a cable cutting zone, the frame having a cable opening along a cable axis at the cable cutting zone receiving an end of a cable. The cable preparation machine includes a pulley assembly rotatably coupled to the frame about the cable axis and a drive assembly operably coupled to the pulley assembly to rotate the pulley assembly about the cable axis. The cable preparation machine includes a blade assembly operably coupled to the pulley assembly and rotated with the pulley assembly about the cable axis. The blade assembly includes a blade having an arcuate cutting edge configured for cutting an insulator from the end of the cable.

A cable-jacket removal tool is described. The tool includes cutting unit that provides a cutting cylinder that carries a blade and a die. The blade is adjustable to provide a desired depth of cut into the cable jacket. The die is interchangeable and selectable based on a diameter or gage of cable to be stripped. A drive unit that is adapted to be driven by a common, handheld, battery operated drill is also provided. The drive unit rotates the cutting cylinder and the blade carried thereby about the circumference of the cable. The drill is coupled to the drive unit such that the axis of rotation of the drill and the cutting cylinder are substantially parallel and an operator can easily apply a force on the tool via the drill in a direction substantially parallel to those axes of rotation.

Techniques, systems and articles are described for preparing electrical cables for connections to a power grid. In one example, a system includes a cable preparation device configured to cut one or more layers of an electrical cable and a computing device configured to control the cable preparation device to cut the one or more layers of the electrical cable.

A cable foil layer processing equipment includes a rack, a knife holder installed on the rack, a plurality of cutters movably installed on the knife holder and arranged in a crisscross manner in a vertical plane, and a linear moving mechanism configured to move linearly in a horizontal direction parallel to an axial direction of a cable. The rack is installed on the linear moving mechanism so as to move linearly in the horizontal direction along with the linear moving mechanism. The cutters clamp a foil layer of the cable in a radial direction of the cable. The linear moving mechanism drives the knife holder to move in the horizontal direction so as to cut the foil layer of the cable into a plurality of equal parts.

A coupling device for coupling an electrical wire to a pull line includes a main body, a connector, a blade and a fixating element. The main body has a longitudinal direction. The connector is for connecting the main body to the pull line. The blade is coupled to the main body. The main body forms a space for receiving the electrical wire. The blade is configured to create a cut in the electrical wire. The fixating element is configured to fixate the blade in the cut. The fixating element is moveable relative to the main body. The main body includes an opening for receiving the fixating element. The opening is at an offset from the blade along the longitudinal direction.

An axial direction moving mechanism has a function of moving the rotary head and the cable holding mechanism relative to each other in an axial direction of the rotation shaft, positions a blade edge of the peeling cutter and the cutting cutter in the axial direction with respect to the cable by moving and stopping, and peels the coating on a tip end side by moving the rotary head and the cable holding mechanism in a direction away from each other in a state where the blade edge of the peeling cutter is cut into the coating of the terminal portion of the cable.
