The tool includes a cable support member and an adjustable frame disposed between the cable support member and the blade housing assembly for adjusting the cable support member toward and away from the blade housing assembly for scoring various diameter cables, the blade housing carrier secured to one end of the adjustable frame. The blade is adjustable within the blade housing opening toward and away from the cable support member for controlling a depth of the blade into the cable sheathing.

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.

A coating stripping device includes a rotation driving tool and a coating stripping tool. A rotating disk of the rotation driving tool includes a first rotating disk having a projection, and a second retaining member of the coating stripping tool has a feather-shaped part. The coating stripping tool in the released state is attached to the second rotating disk and the first rotating disk rotates in a predetermined direction to bring the feather-shaped part into contact with the projection, thereby switching the coating stripping tool into the retained state, and when the coating stripping tool is in the retained state, the first rotating disk rotates in a direction opposite to the predetermined direction to bring the feather-shaped part into contact with the projection, thereby switching the coating stripping tool into the released state.

A tool for removing of one or more outer layers of a multi-layered jacketed wire includes a base member and a top member pivotally connected to the base member. The scoring tool has a first receiver recess on a first end of the scoring tool. A first cutter extends into a first receiver recess at a distance (d.sub.1) from an interior wall of the first receiver recess, and the first cutter is transversely oriented within the first receiver recess. A second cutter extends into a second receiver recess at a distance (d.sub.1) from an interior wall of the second receiver recess, and the second cutter is longitudinally oriented within the second receiver recess.

A stripping tool for a cable includes a cutting unit with at least one blade, a cable seat, and a kinematic structure. The kinematic structure is operatively coupled with the cutting unit to move the at least one blade radially with respect to, and rotationally around, a tool axis and the cable seat. A method for stripping a cable includes moving a plurality of blades of a cutting unit with respect to each other radially to and rotationally around a tool axis. The method includes controlling and coordinating the movement of the blades via a kinematic structure.

One embodiment is directed to a tool to cut and strip a radiating coaxial cable. The tool comprises first and second jaws, a linkage that couples the first jaw to the second jaw, a cutting blade, and a stripping blade. The tool is configured to position at least a portion of the cutting blade to cut and sever the cable at a first point along the cable when the tool is rotated around the cable while the first jaw and the second jaw are closed around the cable. The tool is configured to position at least a portion of the stripping blade to cut the jacket of the cable, without severing the cable, at a second point along the cable when the tool is rotated around the cable while the first jaw and the second jaw are closed around the cable. Other embodiments are disclosed.

A tool for removing a coating from an end of a coated conduit comprising a metallic conduit having an outer diameter and a polymeric material applied over the outer diameter thereof is provided. The tool comprises: a guide member having an outer diameter sized to fit within an internal diameter of the metallic conduit; and a cylindrical cutting member having a substantially closed first end rotatably connected to an arbor, a substantially open second end, and a plurality of teeth elements. The cylindrical cutting member has an inner diameter that is substantially equal to the outer diameter of the metallic conduit such that when the cylindrical cutting member is rotated, the teeth elements remove the polymeric material from the outer diameter of the metallic conduit.

A system and a method for removing a portion of an electric submersible pump power cable conduit housing are provided. The method may include cutting a conduit housing of the conduit, sliding the cut conduit housing off the conduit, and squaring an end surface of remaining conduit housing. The cutting of the conduit housing is not a through cut and the sliding of the cut conduit housing off of the cut conduit is performed with a conduit housing spreader. The system may include a conduit housing cutter for cutting partially through the conduit housing of the conduit and a conduit housing spreader for pulling the portion of the conduit housing apart from a remaining conduit housing. In addition, the system may include a squaring tool to square an end surface of the remaining conduit housing relative to an axis of the conduit.
