Seismic responses of a long-span transmission tower and tower-line system

open access: yesJournal of Physics: Conference Series, 2022
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.

De-icing Method for Coupled Transmission Tower-Line System

open access: yesEnergy Procedia, 2012
AbstractFor the disaster brought by the transmission line regelation, a new de-icing method is presented in this paper. It is supposed that the ice and transmission line are combined closely when there is no external loads, the composite structure of ice-transmission line is set up, then the coupled model of the composite structure-tower is set up. The

Investigation and Development of a Three-Dimensional Transmission Tower-Line System Model Using Nonlinear Truss and Elastic Catenary Elements for Wind Loading Dynamic Simulation

open access: yesShock and Vibration, 2021
The accuracy of transmission tower-line system simulation is highly impacted by the transmission line model and its coupling with the tower. Owing to the high geometry nonlinearity of the transmission line and the complexity of the wind loading, such ...

Icing risk assessment and reinforcement measures of 500 kV transmission tower

open access: yes电力工程技术, 2023
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

open access: yesJournal of Physics: Conference Series, 2023
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.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
