On July 25, the Wuchuan 500 kV power transmission and transformation project officially started. The project is located in Wuchuan County, Zunyi City. It includes the construction of the 500 kV Wuchuan Station (equipped with key equipment such as transformers, vacuum circuit breakers, isolating switches, etc.), and the expansion of the 500 kV Shixiang Station (with the addition of drop-out fuses for protection). line safety) and the line works that connect the two. The long-term planning of the main transformer of Wuchuan Station is 3.75 million kVA, and it is designed to have 7 outgoing lines. In this phase of construction, it will achieve a capacity of 1.75 million kVA in advance, and configure a corresponding number of outgoing lines; Shixiang Station has expanded one circuit The outgoing line is directly connected to Wuchuan substation. In addition, a new 500 kV line from Wuchuan substation to Shixiang substation was built, with a total length of 129 kilometers. Lightning arresters were installed along the line to enhance lightning protection capabilities.
The construction of this project is not only an active response to Guizhou's Western Development Comprehensive Reform Demonstration Zone, Consolidation and Expansion of Poverty Alleviation Achievements Demonstration Zone, Digital Economic Development Innovation Zone, Ecological Civilization Construction Pioneer Zone, and the "Four Zones and One Highland" new highland for the inland open economy. "This is an important step in the strategy, and its completion will greatly meet the growing power load demand in the northeastern region of Zunyi and play a strong supporting role in promoting the coordinated economic and social development of the region.
