摘要： Systems, methods and tools for the interrogation of fiber-reinforced composite strength members to assess the structural integrity of the strength members. The systems and methods utilize the transmission of light through optical fibers that are embedded along the length of the strength members. The inability to detect light through one or more of the optical fibers may be an indication that the structural integrity of the A strength member is compromised. The systems and methods may be implemented without great difficulty and may be implemented at any time in the life cycle of the strength member, from production through installation. The systems and methods have particular applicability to bare overhead electrical cables that include a fiber-reinforced strength member.

摘要： 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.

摘要： 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.

摘要： A termination arrangement for securing an overhead electrical cable and a method for securing an overhead electrical able. The termination arrangement includes a longitudinally-extending sheath having a high tensile modulus that is configured to receive a strength member of the overhead electrical cable therein. When a connector body is crimped over the strength member, the sheath substantially reduces the tensile strain experienced by the strength member and reduces the risk of fracturing the strength member.

摘要： 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.

摘要： Hardware components for the termination and/or splicing of overhead electrical cables that have optical fibers associated with the cable. The hardware components enable access to the optical fibers for connecting to interrogation devices or for connecting to telecommunications equipment. The hardware components also enable the optical fibers to pass through terminations and splices without damaging the optical fibers.
