Modeling Sudden Ice Shedding From Conductor Bundles [PDF]
IEEE Transactions on Power Delivery, 2013 Sudden ice shedding from conductor bundles was modeled numerically and experimentally by improving the approaches proposed formerly for a single cable. The experimental study was carried out on a small-scale laboratory model of one span of a twin bundle.

Wind-Induced Response and Its Controlling of Long-Span Cross-Rope Suspension Transmission Line
Applied Sciences, 2022 In mountainous areas, the installation of steel towers was the major obstacle to the construction of transmission lines. In long-span cross-rope suspension (CRS) structures, the conductors are supported by hundreds-meters-long suspension cables crossing ...

Study on the Maximum Ice-Shedding Height of Conductor Based on Energy Method
IEEE Access, 2023 Ice shedding of transmission lines may lead to interphase flashover and thereby endanger power transmission. The ice shedding of transmission lines is essentially an energy conversion process.

Numerical Simulation of Fluid-Structure Interaction of D-shape Iced Conductor
European Journal of Computational Mechanics, 2019 At present, the numerical simulation on the aerodynamic response and force of the iced conductor are mainly based on the quasi steady criterion, which ignored the interaction between the conductor and the flow field. This paper presents a numerical study
