Abstract: In order to reduce the wind pressure on the surface of the conductor, scholars at home and
abroad have put forward a series of low-wind-pressure conductors with different section shapes and
validated their working mechanism. However, there are few reports about the structural stability of
the low-wind-pressure conductor and the problem of strand jumping. Therefore, the finite element
model is established for aluminum conductor steel reinforced commonly used and low-wind-pressure
conductor by ANSYS software. Based on criterion of strand jumping occurred on line, the
displacement cloud and structural stability of the wire under different working conditions are
analyzed. At the same time, the relationship between the number of outermost wire strands and the
stability of conductor structure is discussed. The results show that the more the conductor number of
the outer ring, the more stable the wire structure.
