750 kV Jiuquan substation 330kV equipment charged successfully

At 2:30 a.m. on September 24th, under the precise command of the Engineering Commission, with the concerted efforts of various participating units and the intense operation of the site for nearly 10 hours, the 330kV Jiuquan substation 330kV equipment was successfully charged. In the northwestern part of Xinjiang, the Gansu section of the network project was re-acquired after the electrification of the 330 kV plant in Hexi in September 18th.

The start-up work started formally at 16:36 on September 23.

The 750 kV Jiuquan substation project is an important part of the northwest- Xinjiang joint project in Gansu Province. The station is located in Dongdong Township, Suzhou District, Jiuquan City. In this phase, a 2100 megavolt-ampere main transformer and 750 kV line will be built. 4 times, 330 kV line outgoing 4 times.

The station entered the electrical installation stage on May 20 this year. On September 18th, it completed completion acceptance of the 330kV spring Zhang 2nd and Quanjia 2nd new section so that the Jiuquan 330kV equipment was ready for operation. .

At present, more than 800 builders are fighting at the front line of the Jiuquan substation project. They are fully engaged in the final commissioning and finishing of main transformers and 750 kV systems.
