STUDY ON IMBALANCE TENSILE FORCES WITH TOWER FOR NON-CONTEMPORANEOUS ICE SHEDDING
Based on analysis of a mass of references, this paper summarizes and analyzes the formative causes of ice shedding, its factors, and damages are summarized. According to the characteristics of the noncontemporaneous ice shedding, the imbalance tensile forces of conductors in the same dead-end section are analyzed. As to the non-contemporaneous ice shedding, the results show that, the location for ice-shedding span will affect the maximum uneven tension and the maximum sag variation. When the ice-shedding span is close to the strain segment, the straight-line tower will withstand the maximum imbalanced-tension. While the ice-shedding span is the middle of the strain segment, it will produce maximum sag variation. Therefore, the key positions of new established transmission towers should be reinforced according to the meteorological conditions.
