Project Record
750 kV Kuqa To Aral And Bachu Transmission Project
Jinhao developed an extra high mechanical strength insulator of 420 kN to meet the specific needs of SGCC for this project.
Project Background
On 25 December 2025 the 750 kilovolt transmission and substation project from Kuqa to Aral to Bachu was put into operation, completing the Aral ring network and with it Xinjiang's Seven Inner Ring Networks main grid framework.
The Challenge
The project carries a total investment of 3.04 billion yuan, runs from the Kuqa 750 kV substation to the Bachu 750 kV substation with a newly constructed Aral 750 kV substation, and has a line length of 485.029 kilometres across arid southern Xinjiang terrain.
What We Supplied
Jinhao developed an extra high mechanical strength insulator of 420 kN to meet the specific needs of SGCC for this project.
Outcome
Result
The Aral loop network was the last ultra-high-voltage loop network project commissioned during the 14th Five-Year Plan period in Xinjiang. The full loop comprises three 750 kilovolt transmission and transformation projects across four substations with a total line length of 1458 kilometres.
Customer Benefit
According to State Grid Xinjiang Electric Power, the completed loop raises power interconnection capacity between southern and northern Xinjiang by 400000 to 500000 kilowatts, meeting demand for large-scale renewable development and transmission in southern Xinjiang and easing regional power supply pressure.
