Abstract or Summary
  • This thesis presents the creep properties and the relations between stress and strain of "Expanded 460KV", "Chukar" and "Drake" conductors. The basic theories of the effect of load, material, and temperature on the conductor are also briefly discussed. The long time creep curve of a conductor appears as a straight line in log-log plot. The stable period of this curve after prestressing is directly affected by the prestress load and time. The conductor's initial strain is increased if the conductor is reeled or severely bent. The slope of the stress-strain curve of a conductor is only slightly affected by the long time creep. It is also slightly influenced by the initial condition of the conductor. However, the complete stress strain curve will move to the right of where it should be if the conductor is severely reeled or bent. Repeated temporary load (wind and ice) will increase the non-elastic elongation of a conductor. The configuration of stress-strain curve of a conductor is different from that of a homogeneous metal. A hysteresis loop always exists between stress-strain curve of loading and the curve of unloading.
