Abstract: Electrical line hardware such as termination arrangements and splices for use with overhead electrical cables that enable the interrogation of the overhead electrical cables through the hardware. The hardware includes at least one port to facilitate access to the strength member of the electrical cable so that interrogation instruments may operatively couple to the strength member and to interrogation elements such as optical fibers associated with the strength member. The interrogation may occur after the overhead electrical cable has been fully tensioned and secured by the hardware, e.g., secured to a support tower.

Abstract: Strength member assemblies including a strength member and at least one glass optical fiber operatively coupled to the strength member. The optical fiber is coupled to the strength member in a manner such that mechanical strains experienced by the strength member are transferred to the optical fiber so that the optical fiber may be interrogated to assess the state of the strength member.

Abstract: Electrical transmission and distribution lines and methods for the installation and interrogation of such electrical lines. The electrical lines include overhead electrical cables that include a strength member and at least one optical fiber coupled to the strength member. Termination arrangements are configured to secure the electrical cables to a support tower while enabling the passage of the optical fiber(s) through the termination arrangement without damaging the optical fibers. Optical fibers from two adjacent electrical cable segments may also be fused to enable the interrogation of the two cable segments from a single interrogation device.

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.
