Abstract

A clamp-conductor system in power transmission lines serves two main functions: to withstand the conductor’s tensile forces and to ensure reliable, continuous electrical current transfer. This study investigates the mechanical and thermal performance of a typical dead-end tension clamp-Lynx conductor system. A finite element model was developed to simulate the system’s response to tensile and thermal stresses. The results indicate that the highest tensile stresses occur in the conductor’s steel core and the clamp’s steel anchor. Thermal performance was evaluated through both finite element simulation and laboratory current-injection testing. Findings show that the conductor’s surface temperature is consistently higher than that of the clamp, and both temperatures increase with rising current. The maximum difference between simulated and experimentally measured conductor surface temperatures was less than 2%, validating the accuracy of the simulation approach.
