Recently, the Laos Mengsong 600MW Mountain Wind Power Project – Asia's first cross-border new energy transmission project and undertaken by Power China Huadong Engineering Corporation Limited (HUADONG ENGINEERING) as the general contractor – has made key progress. The 500kV step-up substation and two 115kV step-up substations have successfully realized back-to-back power transmission, laying a solid foundation for the grid-connection and power generation of the first batch of units.
In this milestone project, Zhejiang Juhonkia Intelligent Electric Co., Ltd., relying on its solid technical strength and product reliability, has provided 40.5kV gas-insulated ring main units (RMUs) with a total value of nearly 20 million yuan for the project, becoming one of the core forces in the construction of this international green energy project.
Participate in the Construction of Cross-Border Green Energy Corridors with Advanced Technology
The Mengsong Mountain Wind Power Project in Laos is a landmark project under the Belt and Road Initiative jointly built by China and Laos, and also one of the largest-scale wind power projects in Southeast Asia. After its completion, the project will not only provide clean energy for Laos, but also transmit green electricity to Vietnam through cross-border power transmission channels, which is of great significance for the regional energy structure transformation and the achievement of carbon neutrality goals.

As a leading enterprise in China’s intelligent power distribution equipment sector, Juhonkia has deeply participated in the construction of the project’s power system. Addressing the complex mountainous environment and high reliability requirements, the company has customized a 40.5kV gas-insulated ring main unit (RMU) solution.
Famous for its compact structure, high insulation performance and excellent environmental adaptability, this equipment can operate stably under harsh conditions such as high temperature, high humidity and heavy dust. It ensures the efficient collection and safe transmission of wind power, and serves as a key link connecting wind turbine units and step-up substations.

Forge Ahead in the International Market and Demonstrate Intelligent Manufacturing Strength with Outstanding Performance
A relevant person in charge of Juhonkia stated that winning the bid for the Laos Mengsong Project marks a major breakthrough in the company’s internationalization strategy. The project team strictly implemented international standards throughout the entire process from design, production to testing, overcame technical difficulties such as equipment moisture resistance and earthquake resistance, and finally won the recognition of international partners with high cost-effectiveness and customized services. “This cooperation not only verifies our technical strength, but also provides a benchmark case for Chinese intelligent electrical equipment to ‘go global’.”
As the Laos Mengsong Project enters the final sprint phase for grid connection, the ring main units provided by Juhonkia have been fully put into operation, laying a solid foundation for the large-scale grid connection of wind turbines in the subsequent stage. In the future, the company will continue to focus on the new energy field, use intelligent and green products to support the global energy transition, and convey the innovative strength of Made in China to the world.
500kV Step-Up Substation
Juhonkia specializes in the R&D and manufacturing of intelligent power distribution equipment. Its product range covers series such as ring main units, circuit breakers, and intelligent substations, which are widely used in fields including new energy, rail transit, and industrial power grids.
Adhering to the strategy of "Technology-Driven, Global Layout", the company has participated in a number of major domestic and international energy infrastructure projects, and promotes the intelligent upgrading of power systems with high-quality solutions.
