Carbon fiber composite core conductor is a new construction, which is new overhead transmission times the capacity of the conductor. Transmission line times the capacity of the transformation project has great potential for exploration, but due to the short time put into actual operation, the research is relatively weak, and cannot accurately assess its characteristics, therefor resulting in the further promotion of carbon fiber conductor application is limited. In this paper, based on the geographical characteristics of carbon fiber conductors in actual operation, a set of" inflection point temperature" model for carbon fiber conductors is built, measuring the stall distance L, height difference angle β and initial temperature t0 of carbon fiber composite core conductor. So based on the stall distance L, height difference angle β and initial temperature t0 to calculate the carbon fiber composite core conductors, the theoretical basis at the inflection point temperature, which is for the further study of the arc sag characteristics of the multi-capacity conductor can be made.
