An automated process for producing exposed electrical contact areas on the conductor part of an epoxy coated bus bar. When the epoxy coating is in the glassy state, one can safely and economically, preferably via automated apparatus, put the epoxy into the rubbery state by positioning the bar and applying localized heat at a select area of the coating; monitoring the heating to above the glass transition temperature of the epoxy, bringing cutting tools into contact with the epoxy for cutting and removing the rubbery coating away from the bus bar, and cooling the bus bar to bring adjacent coating back to the glassy state, thereby leaving an exposed electrical contact area of conductor on the bus bar with little or no surface damage.

A shield trim is performed by tearing bunched shield strands circumferentially along a circular edge. The apparatus includes a pair of aligned metal plates that have been drilled through multiple times such that holes of varying diameters pass through both plates. A cable gripper on the entry side of the device clamps the cable in place. A shield gripper on the rear side of the device closes over the exposed shielding of the cable, and the two plates are pushed together. The shield gripper travels with the rear plate, pushing the shield over the wires and causing the shield to bunch between the two plates. With the two plates pushed together, both grippers open and the cable is pulled free from the device. This pull forces a stress concentration which tears the shield strands across the sharp edge of the hole, producing a uniformly trimmed shield.

The invention relates to a device (21) for working an electrical cable (1) which has a sheath (6) and a cable film (5) situated beneath said sheath, comprising an assembly (32) of modules (33, MD1, MD2, MD3, MD4), which are independent of one another, for removing a piece (6′) of sheath and a piece (5′) of cable film from the cable (1). According to the invention, provision is made for the assembly (32) to have a first module (MD1) for cutting off the piece (6′) of sheath from the cable (1), a second module (MD2), which follows the first module (MD1), for reducing the mechanical loadability of the cable (5) in an intended crack position (RP), and a third module (MD3), which follows the second module (MD2) and has the purpose of removing the piece (6′) of sheath and the piece (5′) of cable film from the cable (1) in an automated manner.

The present disclosure discloses a cable and a cable processing method. The cable includes a wire core, a metal braid layer, a magnetic powder layer, a metal shield, an outer sheath and an elastic ring. The metal braid layer includes an inner braid portion and an everted braid portion which are mutually connected. The inner braid portion is wrapped around an outer side of the wire core, the magnetic powder layer is wrapped around an outer side of the inner braid portion, the metal shield is wrapped around an outer side of the magnetic powder layer, and the outer sheath is wrapped around an outer side of the metal shield. The elastic ring is sleeved outside the inner braid portion, the everted braid portion is wrapped around outer sides of the elastic ring and the outer sheath, and the elastic ring covers an end surface of the metal shield.

The invention relates to a device (1) for producing an electrical cable (2) which has a cable film (20). The device has a film working module (9) for reducing the mechanical loadability of the cable film (20) at a crack position (PR) which is provided along a cable centre axis (M). The film working module (9) has a round blade (33) in order to cut into at least one outer layer, which is remote from the cable centre axis (M), of the cable film (20) at the crack position (PR).

Generating an assessment of the suitability of cables, ducts, tubes, pipes and/or other hollow-type of conduits to extraction of cores, conductors, insulation, etc. included therein while still buried in the ground or otherwise positioned out-of-sight so as to be unavailable for visual and/or physical inspection is contemplated. The assessment may be used to indicate a suitability of a cable buried in the ground of a hybrid fiber coaxial (HFC) cable plant to extraction of the type whereby a core of the cable may be extracted using hydraulics while still buried.

A method for manufacturing an electric cable joint is described. The method includes: a step of providing two electric cables, each cable containing an electric conductor and a thermoplastic insulation system surrounding the electric conductor and containing an inner and an outer thermoplastic semiconducting layers and a thermoplastic insulating layer; a step of joining the terminal portions of the electric conductors of the first and second electric cables to form an electric conductor joint; a step of surrounding the electric conductor joint with a joint inner layer of a thermoplastic semiconducting material having a dynamic storage modulus E.sub.1; a step of surrounding the joint inner layer with a joint insulating layer of a thermoplastic insulating material having a dynamic storage modulus E.sub.2 smaller than E.sub.1; and a step of surrounding the joint insulating layer with a joint outer layer of a thermoplastic semiconducting material having a dynamic storage modulus E.sub.3.
