"The main transformer is running normally, and there is no abnormal signal!On December 28, with the issuance of the closing order of the power dispatching and control center personnel of the State Grid Yinchuan Power Supply Company and the operation and maintenance personnel of the substation, it marked the smooth operation of the 220 thousand volt power transmission and transformation project of Diannong in Yinchuan City, Ningxia.
Diannong 220 thousand volt power transmission and transformation project consists of Ningxia's first indoor 220 thousand volt substation - Diannong 220 thousand volt substation, and a total length of 73It is composed of 9 kilometers and 228 base transmission lines with a total investment of 60.5 billion yuan, which is the largest 220 thousand volt power transmission and transformation project in Ningxia.
A total of 6 220 kV 220 kV transmission and transformation lines have been built in the Diannong 220 kV power transmission and transformation project, of which the Helanshan-Diannong power transmission line spans two counties and one district in Yinchuan and Wuzhong cities in Ningxia, becoming the longest line of Yinchuan power grid. Yinchuan power grid is the receiving end of the power grid, mainly from the Qingtongxia 750 thousand volt Helan Mountain substation through five times 220 thousand volt line to the existing power grid, the project in the Helan Mountain-Diannong double return main supply line after the completion of the transmission capacity is equivalent to the sum of the existing five lines, Yinchuan West Power Grid transmission capacity will be greatly improved.
The completion of the Diannong 220 thousand volt power transmission and transformation project will provide strong and reliable power access capabilities for key investment enterprises such as the 50 gigawatt (G12) solar smart factory in Ningxia Central and Ningxia Chuangsheng New Material Technology Co., Ltd. in the national Yinchuan Economic and Technological Development Zone.
