8000kVA 34.5kV/480V Three Phase Substation Power Transformer ONAN Oil Immersed
The 8000kVA 34.5kV/480V three-phase oil immersed substation transformer features a dual low-voltage split winding design (8000/4000-4000kVA), ideal for large-capacity power distribution, renewable energy integration, and industrial use. It improves electrical isolation, limits short-circuit current, and enhances system stability and safety. With aluminum alloy radiators, it ensures efficient cooling, lower weight, and strong corrosion resistance. It is widely used in solar power plants, energy storage systems, manufacturing plants, and utility substations.
