Cheng, Z., 2018. Thermal characteristics of aluminum conductor composite core. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 356–358. Coconut Creek (Florida), ISSN 0749-0208.In this paper, the thermal characteristics of aluminum conductor composite core (ACCC) are studied with the example of ACCC315/40 conductor.The simulation software is used to simulate the relationship between the temperature and the temperature of the conductor under the condition of ACCC, and the influence of the wind speed on the surface temperature of the wire. The results show that with the increasing of numerical operation line current, wire surface temperature will increase, when the environment temperature changes, the temperature of wire will change the wind speed in the range of 0–1m/s, the wire surface temperature drop more largely, as the wind speed increases, the wire surface temperature drops greatly. The research of this paper provides the basis for the real-time monitoring of the conductor.
