​​Connectors provide both structural support and electrical continuity for overhead lines in transmission and distribution systems. Thus, they must withstand any mechanical forces exerted on them via the conductors they connect. When new, it is anticipated that they will withstand >95% of the rated breaking strength (RBS) of the conductor. Several NEETRAC Baseline projects have focused on the electrical, and by consequence, the thermal performance of connectors in a number of applications. The mechanical performance, unfortunately, has generally not been studied because of the many issues observed on the electrical side. This report provides the findings of a recent NEETRAC project to examine how the strength of a span is affected by the number of connectors inserted into the conductor.
