A method of removing insulation from an electrical cable. The method includes: moving a cutting surface of the insulation cutting blade in a rotary direction relative to the insulation of the cable; cutting the insulation to a defined depth with the cutting surface of the insulation cutting blade as the insulation cutting blade is moved in the rotary direction, the defined depth being less than the thickness of the insulation; moving the cutting surface of insulation cutting blade in a radial direction relative to the insulation of the cable; and cutting the insulation from the defined depth with the cutting surface of the insulation cutting blade as the insulation cutting blade is moved in the radial direction. The entire thickness of the insulation is cut by the combination of the movement of the insulation cutting blade in the rotary direction and in the radial direction.

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.

Techniques, systems, and articles are described for preparing electrical cables for connections to a power grid. In one example, a system includes a handheld 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-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.

Electrical power cable preparation techniques to connect to cable accessories for use in a power grid are described. In an example, a system comprises a cross-section sensing module. The cross-section sensing module comprises a camera configured to capture at least one image of an end-face of an electrical cable, a housing configured to position the end-face of the electrical cable substantially perpendicular to an optical axis of the camera and at an imaging distance from the camera, and at least one optical marker configured to indicate a diameter of the electrical cable. The system further comprises an electrical cable preparation device configured to cut at least one layer of an electrical cable, and a computing device configured to display a user interface, the user interface configured to accept user inputs controlling at least one setting of the cross-section sensing module and electrical cable preparation device.

A sheath removal device includes: an electric wire gripping member which grips an electric wire having a wire and a sheath that covers the wire; cutting blades which form a cut in the sheath at a cutting position that is located on a tip side than a position where the electric wire is gripped by the electric wire gripping member; and a sheath gripping member which grips a sheath tip portion that is a portion, from the tip of the sheath to the cutting position, of the sheath. The sheath gripping member peels off the sheath tip portion from the wire by performing a rotation operation about an extension direction of the electric wire and a pulling-out operation on the sheath tip portion.

A cable processing system comprises a stripping device for stripping a segment of an outer cladding layer of a cable. The stripping device includes a support frame, and a mounting plate movably mounted on the support frame between a start position and an end position in the axial direction of the cable. The mounting plate includes a first surface and a second surface opposite to each other in an axial direction of the cable. A plurality of cutting units are mounted on the first surface of the mounting plate for cutting off the outer cladding layer in a circumferential direction of the cable. A plurality of stripping units are mounted on the second surface of the mounting plate for slicing the outer cladding layer in the axial direction.

A circular cutting unit for partially cutting one or more layers of a cable or wire along a cutting plane. The circular cutting unit include a knife head including a drive disc and an adjustment disc that are each rotatable about a disc axis. A pair of knife holders that each include a knife blade are pivotally mounted to the drive disc. Relative rotation of the adjustment disc relative to the drive disc causes the knife holders to pivot causing movement of the knife blades toward or away from each other. The circular cutting unit includes a primary drive assembly and an adjustment drive assembly that are each separately operable. The primary drive assembly rotates the knife head at the cutting speed and the adjustment drive assembly rotates the adjustment disc relative to the drive disc.

There is provided a coating moving method for a cable that removes a coating at a terminal portion of a cable, including a step of applying a pressing force having such a magnitude that a cutting edge stops at a position before reaching the core wire to the cutting blade to make an incision on the coating by the cutting blade, a step of twist-cutting an uncut portion of the coating between the cutting edge of the cutting blade and the outer periphery of the core wire by rotating the coating on a distal end side from an incision position with respect to the coating on a base end side, and a step of removing the coating on the distal end side from the incision position by gripping and pulling out the coating on the distal end side from the incision position to expose the core wire.

A stripping system that includes a securement device including a receiver platform and an engagement platform sized to receive at least a portion of a large diameter cable having an outer jacket defining a thickness of at least 0.5 mm. The engagement platform translates relative to the receiver platform to secure the cable to the securement device. The system includes a cutting device including a receiver platform that includes a first cutting apparatus and an engagement platform that includes a second cutting apparatus. The receiver platform is sized to receive at least a portion of the cable. The engagement platform translates relative to the receiver platform to move the second cutting apparatus toward the first cutting apparatus to define a cutting interface that is sized to partially sever the outer jacket such that at least a portion of the 0.5 mm thickness of the outer jacket remains partially intact.
