Learn More →Historically recognized as a vital transport, logistics, and manufacturing hub in Rwanda's Southern Province, the Gitarama market (modern Muhanga and its surrounding areas) is currently undergoing a massive transformation. As grid expansion initiatives roll out under Rwanda's Energy Sector Strategic Plan, reducing electrical distribution losses has become a critical objective.
High-efficiency distribution transformers are the backbones of this grid modernization. Standard stacked core transformers are increasingly being phased out in favor of advanced 3D wound core configurations. These require highly specialized machinery—such as automatic winding machines and annealing furnaces—to produce cores with lower no-load losses, lower noise levels, and better thermal performance. By establishing localized transformer maintenance and production capacity, Gitarama is positioned to service the growing electricity needs of Central and Western Rwanda.

Forging high-performance electrical machinery with deep field experience and scientific rigour.
Shuhong Machinery originated from our founder's insight into machinery manufacturing. Drawing from over a decade of hands-on experience, he witnessed domestic machinery shift from "following" to "running alongside" global peers, sensing the critical need for energy-efficient, intelligent upgrades.
During a State Grid project exchange, the founder observed that traditional transformers suffered from thermal bottlenecks and short operational life. This limited grid stability. Shuhong subsequently focused its entire engineering strength on high-efficiency, energy-saving R&D.
Overcoming funding and technical hurdles, the engineering team worked day and night in labs and workshops. The outcome was a breakthrough transformer design with 30% lower temperature rise and an extended 15-year lifespan, winning high client recognition across domestic and international markets.

Located on the shores of Taihu Lake, Wuxi is a world-renowned center for precision machinery and electrical technology. By drawing raw materials and specialized components directly from local Wuxi supply chains, we ensure optimized cost control, reliable quality control, and rapid manufacturing turnarounds.
Through established freight partnerships via the Mombasa port (Kenya) and Dar es Salaam port (Tanzania), followed by the Northern and Central Corridors directly to Gitarama, we guarantee safe delivery. Every machine is crated in vacuum-packed seaworthy wooden boxes to withstand sea transit and inland road conditions.
How our advanced machinery addresses specific challenges in Central Rwanda’s expanding power grids.
Decentralized hydro and solar projects in rural regions outside Gitarama require robust transformers. By utilizing 3D wound cores, manufacturers can produce transformers that withstand fluctuating off-grid loads with minimal core degradation.
Commercial expansion inside modern Muhanga requires safe, dry-type transformers. Producing dry-type units locally using our foil winding machines ensures complete safety, zero oil leakage risk, and compliance with strict urban build regulations.
Rebuilding older transformers instead of importing new ones reduces carbon footprints and operational costs. Setting up vacuum annealing ovens and silicon steel core turning tables locally speeds up transformer repair times.
