Jiangxi Power Grid adopted a small cross -section double rocked arm landing on the ground for the first time success

On July 1, the 500 kV line project of Ji'andong to Wenshan Gengan Dong to Wenshan adopted a new small cross -section double rocker landing on the ground. Improving the efficiency of the operation of the tower, and effectively reducing the safety risk of construction operations.

The 500 -kV Jiwen line project starts from the 500 kV substation of Ji'an East. It ends at Wenshan 500 kV substation. The new line is 75.2 kilometers long and a total of 178 bases of iron towers. The operation point of the pilot pilot pilot pilot of the small cross -section double rocker setting rod group is located at the scene of the project 139. The project department attaches great importance to this. The temporary party branch launch party members and young employees to take the lead in technical research to lay a security and technical foundation for the first time for the landing pole.

In order to actively respond to and vigorously promote the "standardized design, mechanized construction, and assembly operation" construction model of State Grid Jiangxi Provincial Electric Power Co., Ltd., and achieve the overall goal of "mechanical replacement, equipment reduction with people" The company vigorously promotes mechanized construction and continuously introduces and develops new construction equipment that meets the needs of engineering construction.

If the Tower 139 adopts the tower construction plan, it is affected by external factors, low security, and high requirements for terrain. Compared with the traditional group tower method, the small cross -section double rocker's landing rod has a simple, high stability and safety, and the construction monitoring and system control are more simplified. At the same time, the rocker arm is 12 meters long, which can achieve ± 135 ° two -way rotation, which can be quickly set with a hanging tower material. At the same time, it is also suitable for steep mountain terrain, which greatly improves construction efficiency. (Cai Wei Zhoukai)
