This cost-effective 630kVA 10/0.4kV oil immersed step-up transformer complies with IEC 60076 standards, an economical power conversion solution ideal for PV systems, rural electrification and small industrial projects, especially African power construction.
As shown in the picture, it features an integrated corrugated radiator tank with light grey anti-rust coating. The folded radiators deliver efficient heat dissipation for continuous full-load operation, adapting to Africa’s high-temperature outdoor environments while preventing oil leakage and cutting maintenance work. Multi-layer umbrella-type high-voltage porcelain bushings are mounted on the top cover, offering great insulation, lightning and pollution resistance against dust, rain and coastal salt fog. Lifting lugs and mounting holes are reserved for easy transport and on-site installation.
Inside, high-grade silicon steel core and full copper windings lower power loss. The fully sealed oil tank blocks moisture and air to slow oil aging, extending service cycles. With Dyn11 connection group, it balances three-phase current and suppresses harmonics for steady power output. Supporting 50/60Hz optional frequency, it can also be customized to 11kV/33kV high voltage for African 415V low-voltage grid standards.
Compared with premium dry-type transformers, this oil model balances stable performance and affordable factory cost, maximizing cost efficiency for bulk EPC project procurement. It boasts strong overload capacity and simple annual maintenance, perfectly fitting remote areas with limited technicians.
Widely applied in solar PV stations, village mini grids, small factories, residential zones and irrigation pump stations. We offer factory-direct FOB prices, custom specifications and complete COC/PVOC certificates for African customs clearance.
