Filed:

Mar 6, 2008

Appl. No.:

12/074996

Inventors:

Clement Hiel - Rancho Palos Verdes CA, US
George Korzeniowski - Woodland Hills CA, US
David Bryant - Laguna Beach CA, US
Douglas Pilling - Bonita CA, US
William Ferguson - Vista CA, US
Eric Bosze - Los Angeles CA, US

International Classification:

B32B 17/02

US Classification:

4282994, 4283007

Abstract:

A composite core for an electrical cable, the composite core defining a longitudinal axis that defines a center of the composite core, the core comprising a plurality of longitudinally extending reinforcing fibers embedded in a resin matrix, the fibers oriented substantially parallel to the longitudinal axis and a sheath surrounding the plurality of longitudinally oriented fibers. The sheath may further comprise a plurality of off-axis reinforcing fibers oriented at an angle relative to the longitudinal axis surrounding the longitudinally extending fibers. The sheath may comprise a type of resin, including for example, thermosetting resin or thermoplastic resin.

H02G 7/00

Abstract:

A bare overhead electrical cable and a method for the manufacture of an overhead electrical cable. The electrical cable includes a central strength member and at least two conductive layers surrounding the strength member, the two conductive layers being formed from first and second conductive strands respectively. The first conductive strands are formed from first aluminum material and the second conductive strands are formed from a second aluminum material, where the second aluminum material has at least one material property that is different than the same material property of the first aluminum material. For example, the second conductive strands may be formed from an aluminum material having a lower conductivity but higher hardness than the first aluminum material. Such a configuration may be useful when the overhead electrical cable is installed in a geographic region that is subject to heavy ice loading.

H02G 7/00
H02G 1/02
H01R 11/12

Abstract:

A termination arrangement for securing an overhead electrical cable to a dead-end structure such as a dead-end tower. The termination arrangement includes a compression sheath that is configured to be disposed between a strength member and the conductive strands of the overhead electrical cable. The compression sheath mitigates damage to the strength member that may occur when an outer metallic sleeve is compressed around the conductive strands and the conductive strands are compressed against the strength member. The arrangement is particularly useful for securing overhead electrical cables having a composite strength member to a dead-end structure.

Abstract:

A termination arrangement for securing an overhead electrical cable to a dead-end structure such as a dead-end tower. The termination arrangement includes a compression sheath structure that is configured to be disposed over the individual composite rods of the strength member. The compression sheath structure mitigates damage to the strength member that may occur when an outer metallic sleeve is compressed around the conductive strands and the conductive strands are compressed against the strength member. The arrangement is particularly useful for securing overhead electrical cables having a composite strength member to a dead-end structure.
