International Classification:

H01B 1200

US Classification:

1741251, 505886, 505887

Abstract:

In order to provide a flexible oxide superconducting cable which is reduced in AC loss, tape-shaped superconducting wires covered with a stabilizing metal are wound on a flexible former. The superconducting wires are preferably laid on the former at a bending strain of not more than 0. 2%. In laying on the former, a number of tape-shaped superconducting wires are laid on a core member in a side-by-side manner, to form a first layer. A prescribed number of tape-shaped superconducting wires are laid on top of the first layer in a side-by-side manner, to form a second layer. The former may be made of a metal, plastic, reinforced plastic, polymer, or a composite and provides flexibility to the superconducting wires and the cable formed therewith.

US Classification:

174110R, 174120 R, 427118

Abstract:

The present invention includes a cable having reduced surface friction and the method of manufacture thereof having steps in which a conductor wire is coated with a mixture of a plastic material and lubricating material and in which the coated conductor wire is cooled. The cable includes at least one conductor core and at least one coating of plastic material and incorporates a lubricating material in and/or on the plastic material. The equipment for the manufacturing of electrical cable includes a reel for supplying a conductor wire to an extruding head, which is connected to tanks containing plastic material and lubricating material for coating the conducting wire, and a reel for taking up the cable.

US Classification:

174110R, 174120 R, 427118

Abstract:

Disclosed is a method of manufacturing a finished cable by a process directed to reduce the amount of force required to install the cable. The process involves the extrusion of the cable's outer sheath and the incorporation of a pulling lubricant in connection with, and prior to the completion of, the extrusion to reduce the sheath's surface coefficient of friction as well as reduce the required force to pull the cable for installation. The conductor core is coated with an extruded plastic material with which an appropriate (in amount and type) pulling lubricant is initially combined with the plastic material prior to the formation of the sheath and in which the sheathed conductor core is thereafter cooled, the lubricant either migrating to and/or permeating the sheath to be available at the surface of the sheath at the time of the cable's installation. The preselected lubricant is disclosed as either combined with the plastic material during initial pelletization, or mixed with the plastic pellets prior to introduction of the mixture into the extruding head, or introduced into the extruding head at a separate location downstream from where the plastic material is introduced into the extruding head.
