Regional Supplier
Transformer Supplier in Uganda
IEC-certified power transformers and electrical equipment engineered for Uganda's expanding grid, oil and gas developments, and industrial electrification.
Uganda's power sector is entering a transformative phase driven by major hydropower projects, oil and gas discoveries in the Lake Albert region, and ongoing industrial expansion. The national grid operates at 50Hz with transmission voltages of 11kV, 33kV, and 132kV, managed by UETCL (Uganda Electricity Transmission Company Limited) for transmission and UMEME for distribution. End-user supply is standardized at 415/240V three-phase across the country.
The commissioning of the 600MW Karuma and 183MW Isimba hydropower plants has significantly increased Uganda's generation capacity, creating demand for additional substation equipment to evacuate and distribute this power. The development of the Lake Albert oil fields — including the Tilenga and Kingfisher projects — requires substantial electrical infrastructure for upstream processing, refinery operations, and the East African Crude Oil Pipeline (EACOP). As a certified transformer manufacturer, Ziyao Power provides IEC-compliant products configured for these applications.
Our portfolio for the Ugandan market includes hermetically sealed S22-M oil-immersed transformers, SCB13/SCB18 cast resin dry-type transformers, KYN28 MV metal-clad switchgear, GCS LV switchgear panels, and YB Series prefabricated substations. All equipment is designed for tropical conditions with enhanced cooling, corrosion protection, and appropriate insulation coordination for Uganda's equatorial climate and elevation profile.
Karuma & Isimba Hydropower Integration
The 600MW Karuma and 183MW Isimba hydro plants require extensive substation and distribution equipment to evacuate power and connect to the existing UETCL transmission backbone at 132kV.
Lake Albert Oil & Gas Development
The Tilenga and Kingfisher upstream projects plus the EACOP pipeline need reliable transformers and switchgear for wellhead power, processing facilities, refinery operations, and pipeline pump stations.
Industrial Park Expansion
Uganda's Namanve, Luzira, and Mbale industrial parks are expanding rapidly. New manufacturing facilities require complete electrical infrastructure including transformers, MV switchgear, and LV distribution panels.
Rural Electrification Program
The Rural Electrification Agency (REA) continues to extend the distribution network to underserved districts. REA projects require cost-effective distribution transformers and compact substations for villages and trading centers.
Manufacturing Sector Growth
Cement plants (Tororo, Hima), steel mills (Jinja), and food processing factories are expanding production capacity. These industries require high-reliability transformers and MV switchgear rated for continuous operation.
Grid Loss Reduction & Modernization
UMEME is investing in network upgrades to reduce technical losses and improve supply reliability. Replacement of aging transformers and installation of new 33/11kV primary substations is ongoing across the Kampala metropolitan area and regional towns.
Oil-Immersed Distribution Transformers
S22-MHermetically sealed S22-M series for pole-mounted and ground-mounted installations in UMEME distribution networks and industrial facilities throughout Uganda.
Designed with enhanced cooling for Uganda's equatorial climate conditions.

Q: What are UMEME's distribution requirements for transformers?
UMEME specifies transformers manufactured to IEC 60076 with specific requirements for vector group (typically Dyn11 for distribution), tapping range (±2×2.5% as standard), and no-load losses compliant with Uganda's minimum energy performance standards. Our S22-M series transformers are pre-configured to meet these requirements. For contractors bidding on UMEME supply contracts, we provide complete technical submittal packages including IEC type test certificates, factory test reports, and manufacturer's authorization letters.
Q: What voltage standards do your transformers support for Uganda?
Our transformers are wound for Uganda's standard voltages: 11kV and 33kV primary, with 415/240V secondary for three-phase distribution. For generation interconnection at hydropower sites, we also supply 11kV/132kV generator step-up transformers. Custom voltage configurations are available upon request.
Q: Can your equipment handle Uganda's equatorial climate conditions?
Yes. Uganda's climate — warm and humid with significant rainfall — requires special consideration for transformer design. Our units feature tropicalized insulation systems, enhanced ventilation for dry-type units, and C3/C4 corrosion protection paint systems for outdoor enclosures. All transformers are factory tested at elevated ambient temperature and humidity conditions to ensure reliable operation throughout the year.
Q: What is the delivery time for transformers to Kampala?
Standard production lead time is 6–8 weeks. Overland transport from the Port of Mombasa (Kenya) to Kampala typically takes 4–7 days after customs clearance. We handle all export documentation including COMESA Certificate of Origin for preferential tariff treatment. Total door-to-door delivery including sea freight and inland transport is approximately 10–12 weeks from order confirmation.
Q: Do you have experience with oil & gas sector transformers?
We supply transformers engineered for oil & gas environments including enhanced safety features, corrosion-resistant enclosures for coastal and processing environments, and special paint systems for the Lake Albert region's specific conditions. Our oil & gas transformers include appropriate safety margins for critical process loads and are supplied with full material traceability documentation.
Q: What certification is needed to import transformers into Uganda?
Transformers imported into Uganda require compliance with UNBS (Uganda National Bureau of Standards) requirements. For most electrical equipment, this involves a PVoC (Pre-Export Verification of Conformity) certificate or import clearance through UNBS. Our products come with IEC type test certificates and factory test reports that satisfy these requirements. We assist clients with the UNBS documentation process and can arrange pre-shipment inspection.
