The 330kV 320MVA oil-immersed power transformer is a core component of high-voltage transmission and transformation, suitable for ultra-high voltage power grids. It can meet the power output needs of large power station units or the voltage transformation requirements of regional power grid hubs, fulfilling the functions of large-capacity power transmission, transformation, and power distribution.It utilizes a high-quality silicon steel core, low-loss windings, and a fully sealed heat dissipation system, resulting in low losses, low noise, and high short-circuit resistance.With insulation ratings exceeding LI950AC395, it can withstand complex outdoor environments. It can also be equipped with online monitoring and on-load voltage regulation devices to ensure stable and efficient power grid operation.
