Seismic responses of a long-span transmission tower and tower-line system
The seismic responses of a long-span transmission tower (LTT) and tower-line system (TL) are presented in the paper. The mode decomposition response spectrum method (MDR) and time domain analysis method (TD) are both employed to obtain the seismic responses.

Icing risk assessment and reinforcement measures of 500 kV transmission tower
The existing of transmission line icing may lead to the collapse of the transmission tower and disconnection of the transmission line, which seriously threatens the safe and stable operation of power grid. In this paper, aiming at the typical icing lines

Wind induced coupling effects of transmission tower-line system at microtopography
Abstract The coupled and uncoupled Dynamic Finite Element Models (DFEMs) of the transmission tower-line system consisting of two towers and three spans of conductors and ground wires were built at the windward and crosswind slope of a cosinoidal hill.

Dynamic response analysis of transmission tower line system under random fluctuating wind field
The transmission tower and tower line coupling system is an important carrier of the power system transmission process. Strong winds in coastal areas have a significant impact on the transmission tower and tower line system. To study the dynamic response

Research on the Wind-induced Vibration Coefficient of Transmission Tower-line System
AbstractThe six different non-linear finite element model of the transmission tower-line system which have different spans and different height difference was established by the finite element analysis software, and wind velocity time series with resorting to weighted amplitude wave superposition (WAWS) was simulated.

ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...
