A multicore cable is composed of a bunched core composed of a plurality of electric wires laid together, each including a conductor, and an electrical insulating member provided over a periphery of the conductor, an abrasion suppressing layer configured as a taping member helically wrapped around a periphery of the bunched core, a shielding layer composed of a braided shield provided over an outer periphery of the abrasion suppressing layer, and a sheath provided over a periphery of the shielding layer. An opposite surface of the taping member constituting the abrasion suppressing layer to the bunched core and an opposite surface of the taping member constituting the abrasion suppressing layer to the shielding layer are composed of a fluoropolymer resin. The taping member constituting the abrasion suppressing layer is non-adhesively lap wound in such a manner as to partially overlap itself in a width direction thereof.

Disclosed is an electrical cable for vertical applications, comprising a core having a length L, a sheath surrounding the core and extending through the whole length L and a reinforcing jacket surrounding the sheath and in direct contact therewith. The reinforcing jacket is made of concentric layers comprising a first layer longitudinally extending from a first cable end (the proximal or upper cable end, in use) towards a second cable end (the distal or lower cable end, in use) substantially along the whole length L. The reinforcing jacket also comprises at least one further layer longitudinally extending from the first cable end towards the second cable end for a length shorter than L. At least one layer of the reinforcing jacket is a circumferentially closed metal tube. Also disclosed is a process for manufacturing such cable.

Electrical cables and processes for making and using same. In some examples, the electrical cable can include one or more insulated electrical conductors and one or more metallic elements cabled together and a metallic layer disposed about the one or more insulated electrical conductors and the one or more metallic elements. The one or more metallic elements can partially fill a space located between the one or more insulated electrical conductors and the metallic layer. The one or more insulated electrical conductors can each include an electrically conductive core, a layer of electrically insulating material disposed about the electrically conductive core, and a layer of metallic strands disposed about the layer of electrically insulating material.

A reinforced superconducting wire (1a) has a superconducting core strand (2) and a first cladding with a multitude of reinforcing strands (3). The reinforcing strands (3) are arranged around the circumferential surface of the superconducting core strand (2) in a non-crossing manner and are in contact with the core strand (2). The wire has a reinforcement for enhancing its mechanical properties against external stresses and for preventing diameter expansion during heat treatment. In addition to other advantages, such superconducting wire can be produced with an easy and low-cost production process.

A dielectric isolator for a twisted pair cable includes a body formed as an elongate strip with a top surface, bottom surface, a first side edge and a second side edge. A first slot is formed in the first side edge and extends at least half way toward the center of the isolator. A second slot is formed in the second side edge and extends at least half way toward the center of the isolator. During cable manufacturing, first and second wedges open the first and second slots. First and second twisted pairs are inserted into the first and second opened slots, respectively. Third and fourth twisted pairs reside at the top and bottom surface, respectively. The isolator has the cost and reel storage savings of a flat separator tape, while simultaneously providing the internal crosstalk performance of the isolator.
