Expanding Its Belt and Road Presence: CGNNT Delivers Bangladesh's First Industrial Electron Beam Accelerator

Recently, CGN Dasheng Accelerator Technology Co., Ltd. (CGN Dasheng), a subsidiary of CGN Nuclear Technology Development Co., Ltd. (CGNNT), successfully delivered its independently developed DD-series 2.5 MeV horizontal, semi-self-shielded high-frequency, high-voltage electron accelerator to a leading cable manufacturer in Bangladesh.
This marks not only CGN Dasheng's first electron accelerator delivered to Bangladesh, but also the country's first industrial electron beam irradiation accelerator, representing a significant milestone in the expansion of China's nuclear technology applications into the South Asian market.

On-site installation and commissioning

The DD-series high-frequency, high-voltage electron accelerator offers a wide range of applications, including material modification, sterilization, and environmental treatment. Its key advantages include a broad energy range, cost-effectiveness, ease of operation and maintenance, and a relatively short construction and installation period.
The delivered 2.5 MeV horizontal, semi-self-shielded model is specifically designed to meet the irradiation crosslinking requirements of medium- and large-sized cables, providing strong technical support for improving product quality and upgrading Bangladesh's cable manufacturing industry.

On-site installation and commissioning

During project implementation, the installation team encountered significant challenges due to site constraints. Limited overhead clearance prevented large cranes from entering the factory, while suitable local lifting equipment was unavailable. As a result, lifting and positioning the accelerator's cylindrical high-voltage tank became a critical challenge.
To overcome this obstacle, the project team developed a practical, site-specific solution by constructing a dedicated load-bearing lifting frame around the component. Using a 20-ton manual chain hoist, the team successfully completed the lifting, positioning, and installation work.
Following more than two months of intensive installation and commissioning, the entire system was successfully installed and passed the customer's on-site acceptance inspection on the first attempt.

CGN Dasheng's flagship product: DD-series high-frequency, high-voltage electron accelerator

The successful delivery of this project provides Bangladesh's cable industry with a reliable solution from CGN, supporting technological advancement and industrial upgrading. It also represents an important step in CGN Dasheng's continued expansion in the South Asian market and its commitment to industrial irradiation technologies.
Looking ahead, CGN Dasheng will build on this milestone by strengthening independent technological innovation and delivering high-performance irradiation equipment and integrated solutions. Through these efforts, the company aims to contribute to the Belt and Road Initiative and support the sustainable, high-quality development of the global cable industry.
