Abstract: In order to study the corona characteristics of aluminum conductor composite core (ACCC), corona onset tests of single ACCC-600/71 conductor and LGJ-630/45 conductor were performed based on the corona measurement system with small corona cage. The experimental result shows that: under clean and artificial smear conditions, the corona onset voltages of ACCC-600/71 conductors are higher than those of LGJ-630/45 conductor, which proves that ACCC-600/71 conductors can reduce the line losses and have good performance in energy saving and environmental protection. Surface contamination reduces the roughness factor of ACCC-600/71 and LGJ-630/45 conductors and greatly lowers the corona onset voltages. The bigger the particle size is, the higher the influence will be.
