Rockwill Group Welcomes High-Level Technical Delegation from Kenya Power (KPLC) to Explore New Opportunities for 230kV Dead Tank Circuit Breaker Cooperation

Recently, Rockwill Group hosted a high-level technical delegation from the Kenya Power and Lighting Company (KPLC). The visit focused on an in-depth technical exchange regarding the entire manufacturing chain of 230kV Dead Tank Circuit Breakers (DTCBs). The delegation observed the complete production process—ranging from high-precision metal tank stamping and SF₆ interrupter sealing to intelligent control module integration and dielectric performance testing. This visit has laid a solid foundation for the full integration of Rockwill’s 230kV DTCBs into Kenya’s "National Grid Upgrade Plan."

As a benchmark Chinese enterprise deeply rooted in the medium-to-high voltage transmission and distribution sector, Rockwill has consistently driven product innovation through its "Environmental Adaptation + Intelligent O&M" strategy. Its 230kV DTCB series has successfully served grid projects in over 40 countries across Southeast Asia, Latin America, and Africa. In several 230kV substation upgrade projects in Nairobi and Mombasa, the series has achieved "zero-fault operation" for three consecutive years. With a power supply reliability rate of 99.99%, it has earned the profound trust of local O&M teams and become a preferred equipment choice for Kenya’s grid modernization.

Currently, Kenya is accelerating its "National Grid Modernization Roadmap" to address critical pain points such as extreme high temperatures, arid dust storms, high line failure rates, difficulties in remote inspection, and grid instability. Rockwill’s 230kV DTCB offers core advantages including a fully sealed SF₆ insulated structure, superior resistance to high temperatures and dust (capable of withstanding extreme temperatures from -5°C to 45°C and resisting heavy sand erosion), and long-term maintenance-free operation (with cycles up to 10-15 years). Proven in multiple Kenyan grid projects, this solution has increased fault handling efficiency by 55% and reduced O&M costs by 70%, making it a key component in enhancing the resilience and reliability of Kenya’s T&D network while perfectly adapting to the local high-temperature, high-humidity, and dusty outdoor environments.

At the conclusion of the visit, David Otieno, Technical Director of KPLC, stated: "The stable performance of Rockwill’s 230kV DTCBs in the high-temperature and dusty environments of Mombasa is impressive. Its fully sealed structure effectively resists dust erosion and extreme heat, fully meeting the rigorous requirements of Kenya’s grid upgrades. We plan to deploy this product in eight new 230kV smart substation projects in regions like Nairobi and Mombasa. Furthermore, we look forward to Rockwill establishing a technical service center in Nairobi to provide localized technical training and rapid fault response support, bolstering Kenya’s grid modernization."

The KPLC delegation’s visit to the intelligent manufacturing base is not only a transparent demonstration of Rockwill’s technical prowess but also a significant milestone in China-Kenya power cooperation. It drives the partnership toward deeper synergy in "products + services + localization." Looking ahead, Rockwill will continue to empower East African grid construction through innovative technology, focusing on the iteration of core products like the 230kV series. By optimizing performance in accordance with IEC 62271-100 international standards, Rockwill aims to join hands with global partners to build a secure, efficient, and sustainable energy future.
