Optimization design of Pre-twisted Suspension Clamp with Large Tonnage and Large Suspension Angle

Abstract

In order to improve the performance of pre-twisted suspension clamp with large tonnage and large suspension angle, an optimal design method of large tonnage and large suspension angle pre-twisted suspension clamp is proposed. Firstly, three-dimensional software is used to build the model, and then, finite element software is used to simulate stress analysis and structure optimization. Finally, taking the 500kv Yangtze River crossing project from Fengcheng to Meili as an example, the opgw-350 large tonnage pre-twisted double suspension clamp with large suspension angle is developed. The experimental results show that the pre-twisted suspension clamp with large tonnage and large suspension angle can meet the engineering requirements.
