Appl. No.:

09/756533

Inventors:

David Reece - Carrollton GA
Jonathan Waller - Carrollton GA
Nick Ware - Villa Rica GA
Philip Sasse - Douglasville GA

Assignee:

Southwire Company, a Delaware Corporation - Carrollton GA

International Classification:

H01B 700

US Classification:

174110R, 174113 R

Abstract:

An electrical cable with a stranded central conductor encircled by insulation including a material which provides self-sealing properties to the cable present at least between the adjacent edges of the stranded conductor and the insulation. Preferably, the material is a polymeric material which is flowable at a temperature at least as low as 25Â C. and has a 100 gram needle penetration value greater than 100 tenths of a millimeter at 25Â C.

International Classification:

H01B 7/00

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.

International Classification:

H01B 7/00

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.

International Classification:

H01R 13/58

US Classification:

439604

Abstract:

Disclosed is type THHN cable having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a nylon sheath. A high viscosity, high molecular weight silicone based pulling lubricant for THHN cable, or alternatively, erucamide or stearyl erucamide for small THHN gauge wire, is incorporated, by alternate methods, with the nylon material from which the outer sheath is extruded, and is effective to reduce the required pulling force on the cable during installation.

US Classification:

174110R, 174116, 174120 R, 156 48, 156 51

Abstract:

An electrical cable and a method for manufacturing the electrical cable are provided in which a plurality of insulated conductors have an inner protective layer extruded thereabout. A plurality of longitudinally extending ribs or fins or exterior ribbed or finned surfaces are formed outward of the inner protective layer between which exist a plurality of voids. An outer insulation layer can be formed in the same operation as the fins or ribbed surface and the inner layer or in a subsequent operation. A self-sealing elastomeric material is applied to the conductor surface or is present between the fins and between the inner protective layer and the outer insulation layer.
