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.
Claims16
A termination arrangement securing an overhead electrical cable to a dead-end structure, the overhead electrical cable having a composite strength member comprising a plurality of individual fiber-reinforced composite rods that are operatively combined to form the composite strength member and having conductive strands surrounding the composite strength member, the termination arrangement comprising:
- a connector anchoring the termination arrangement to the dead-end structure;
- an outer metallic sleeve surrounding the proximal end of the overhead electrical cable, the outer metallic sleeve having a compressed portion disposed over the proximal end of the overhead electrical cable;
- and
- a compression sheath structure comprising a plurality of aluminum cylindrical tubes, wherein each of the plurality of aluminum cylindrical tubes is disposed over a different fiber-reinforced composite rod to create a ductile barrier between each of the fiber-reinforced composite rods along a length of the conductive strands under the compressed portion, wherein the compression sheath structure does not extend substantially beyond the compressed portion of a distal end of the termination arrangement.
