Ronghui Diantong Technology won the bid for the 35kV overhead bare conductor insulation reconstruction project of Datang Yunshan Wind Farm

After experiencing high temperature in summer and heavy load operation, some power equipment inevitably has potential safety hazards.Transmission lines are like human arteries and blood vessels, they are crisscrossing and have many points and wide areas, which are easily affected by tree barriers, buildings and external damage. They are the must check item for the "power autumn inspection" .

Independent research and development| Large Capacity and High Efficiency Insulation Coating Robot leaved factory and had a coating test

Recently, Wuhan Ronghui Diantong received a number of cooperation on the project of electrified insulation coating robots. In May 2023, our company received a group of new customers to visit again.

Accelerate the construction of a new development pattern for power transmission and distribution business

Start is a sprint, run out of "acceleration". Just after the Spring Festival holiday, from the western inland to the eastern coastal, from the Qiongzhou Island to the mountains of Guizhou, thousands of project builders have gone all out to make new breakthroughs in the construction of major projects of China Southern Power Grid Co., Ltd.

The main news section of State Grid News reported the flexible DC transmission technology.

Zhangbei renewable energy flexible DC power grid test demonstration project, Xiamen ±320kV flexible DC transmission science and technology demonstration project, Zhoushan ±200kV five-terminal flexible DC transmission science and technology demonstration project, Shanghai Nanhui flexible DC transmission project... In the field of energy and power, these innovative projects with great scientific and technological demonstration significance all have applied a common advanced technology-flexible DC transmission technology.

New power system leads upgrading of power transmission and transformation enterprises

As a bridge between generator terminal and user side in power system, the transmission and transformation link plays an important role in satisfying users’ demand for electricity and stabilizing the operation of power grid. With the carbon emission peak and carbon neutrality target was put forward, the green electricity of "live at the mercy of the elements" brings great challenges to power transmission and transformation enterprises.

State Grid Gaomi City Power Supply Company: A new generation of distribution automation system to help the operation of the power grid.

State Grid Gaomi City Power Supply Company greatly improves the success rate of distribution network line switches coincidence from less than 50% to more than 70% by using the accurate and efficient fault handling function of the new generation distribution automation system. The company also realizes automatic load transfer in non-fault areas through accurate fault positioning and isolation intelligent distributed self-healing function, and the self-healing rate reaches more than 85% during summer, reducing more than 490 power outages on a year-on-year basis.

In-depth analysis of China's current situation of UHV(Ultra-high Voltage) market and key enterprises

During the "14th Five-Year Plan" period, the construction of large-scale wind power and solar generation bases have been accelerated, the investment scale of power grid has increased, the problems of the new energy grid-connected consumption and the cross-regional power transmission need to be further solved.
