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.

A peeling device for a resin layer coating a rectangular wire in which an outer side of a metal conductor having a rectangular shape in cross section is coated with the resin layer, including a processing blade configured to peel off the resin layer, a jig configured to hold the rectangular wire, and a position detection means configured to detect a position of a cutting edge of the processing blade with respect to a surface of the metal conductor, in which the cutting edge of the processing blade is caused to penetrate into a predetermined thickness position of the resin layer, and the processing blade and the rectangular wire are relatively moved in a longitudinal direction of the rectangular wire without contact of the cutting edge with the metal conductor to perform treatment of peeling off the resin layer.

A separating and/or insulation removal device for a cable-processing machine has at least two knife blocks that can be moved in opposite directions, each with at least one knife. A cable that is to be cut to length and/or is to have its insulation removed can be guided between the knives, which are actuated by at least one drive for at least one of the knife blocks, and a mechanism for purposes of guiding at least the driven knife block in the direction towards the cable. The drive acts at least indirectly on an element of the mechanism. Each driven knife block sits on a lever at a distance from its lever axis and executes a pivotal movement along a circular arc. For this purpose, the drive engages with the lever via a rotatable force transmission element at a distance from the lever axis and the knife block.

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 cutting method of the invention cuts a flat wire covered with a film, using a pair of first blades, and a second blade that is arranged between the pair of first blades. This cutting method includes a step of forming tapered cuts in an upper surface of the flat wire, by the pair of first blades cutting part way into the flat wire in a thickness direction, from the upper surface of the flat wire, and a step of cutting the flat wire by the second blade, between the two cuts, so as to form a chamfer on both side surfaces next to the upper surface of the flat wire.

An installation for assembling cables includes two pivot units and a processing station processing cable ends of the cable, a loop layer forming cable loops from the cable, a loop stretcher and a loop holder having a gripper securing the cable loop. The loop layer and the second pivot unit place the fully assembled cable loop on a cable tray using respective cable grippers. The cable tray is a conveyor having holding elements that hold both cable ends of the cable loop.

Each of cutting mechanisms of a device for forming a notch for stripping includes: a stopper which is capable of approaching and/or being separated away from an outer circumferential surface of a coated electric wire; a biasing part biasing the stopper; a cutter blade; a stopper movement mechanism configured to, when forming a notch, move the stopper together with the cutter blade to bring the stopper into contact with the outer circumferential surface; and a cutter movement mechanism configured to, after bringing the stopper into contact with the outer circumferential surface, forward the cutter blade to a position corresponding to a specified notch depth for forming the notch.

A system for removing a foil shield from a cable comprises an induction coil for inductively heating the foil shield of the cable, a cable feeding device for selectively passing the cable through the induction coil, a cutting blade for selectively removing at least a portion of the cable, and a sensor for detecting at least one characteristic of the cable.
