Techniques, systems and articles are described for preparing electrical cables for connections to a power grid. In one example, a cable-cross-section-measurement tool includes a housing defining a cavity, wherein the housing is configured to position an end-face of an electrical cable within the cavity; a camera disclosed within the cavity of the housing, wherein the camera is configured to capture an image of the end-face of the electrical cable; and a telecentric lens optically coupled to the camera, wherein the telecentric lens comprises a non-angular field of view configured to reduce, in the image, distortion from parallax associated with at least one portion of the end-face of the electrical cable that is oriented at an oblique angle relative to an optical axis of the telecentric lens.

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.

A device for assembling an electrical plan connector on a first cable end and/or on a second cable end of an electrical cable having one or more inner conductors. The device has at least two independent processing modules for processing the electrical cable. The device also has a common transport unit for transporting the electrical cable between at least two of the processing modules along a transport direction.

A system for servicing cable includes a field-end assembly and a live-end assembly, each mounted on a support structure having at least one drive mechanism operable to cause relative linear movement between the field-end assembly and the live-end assembly. A drilling-and-shorting assembly can create a short circuit in a field-end of the cable, and a continuity tester can test the integrity of the short-circuit. The field end of the cable can then be ejected from the system, and an end-cap-cradle assembly can position an end cap on a live end of an electrical cable and test its installation.

A system for removing metal foil shield from electrical wires and/or cables, using ablation process, shear stress generation and video camera feedback.

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 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.

The present invention relates to a method for removing a shielding foil (K2) of an electrical cable (Ka) with a longitudinal axis (L), which cable has, going out from the longitudinal axis outward, an inner conductor (K5), a dielectric (K4), the shielding foil (K2) and an insulating sheath (K1), comprising the following steps: a. Creating an incision (EK) of a first depth (T1) in the insulating sheath (K1) of the electrical cable (Ka), for example by means of the rotating blades (23), of a rotary stripping device whereby the first depth (T1) is smaller than or the same as the thickness of the insulating sheath (K1); b. Creating a predetermined breaking point (S) in the shielding foil (K2) through pressing in of at least one radially adjustable perforation tool through the incision (EK) produced in step a. until the perforation tool has reached a second depth (T2), whereby the second depth (T2) corresponds to at least the thickness of the insulating sheath (K2) plus at least half of the thickness of the shielding foil (K2); c. Tearing the shielding foil at the predetermined breaking point (S); and d. Removing the shielding foil (K2).

The present invention relates furthermore to a device for implementing the method according to the invention.

A cutting arm includes a base having a post receiving passageway extending through the base, a cutting assembly attached to the base, and a sliding plate attached to the base and movable with respect to the base between an engaging position and a releasing position. The sliding plate engages a post disposed in the post receiving passageway in the engaging position and releasably secures the cutting arm to the post.

A method of manufacturing a plurality of conductor elements includes providing the plurality of conductor elements, each conductor element includes a conductor end section having an electrically insulating surface coating; securing the conductor end sections of the conductor elements with respect to each other; and simultaneously removing at least a portion of the electrically insulating surface coatings of the conductor end sections using a machining surface of a stripping tool being moved along the conductor end sections.
