10kV fully sealed oil-immersed transformer developed and produced by Jinma Electric Power has the advantages of low loss, low noise and high energy efficiency, achieving remarkable energy-saving effects and reducing operational costs. Unlike conventional oil-immersed transformers, this fully sealed model eliminates the traditional oil conservator. The expansion and contraction of transformer oil are automatically compensated by the elasticity of the corrugated tank wall, completely isolating the oil from air and moisture. This effectively prevents oil deterioration and insulation aging, significantly enhances operational reliability, and enables maintenance-free operation under normal working conditions.
10kV Hermetically Sealed Oil-Immersed transformers is specially designed with enhanced anti-corrosion treatment for the tank and structural components, making it highly suitable for coastal, high-humidity, chemically corrosive and other harsh operating environments. Equipped with high-quality cold-rolled grain-oriented silicon steel cores and pure copper windings, it boasts strong short-circuit withstand capability, stable performance and long service life. Widely used in urban power grids, industrial parks, mining enterprises and rural power distribution systems, it provides safe, reliable and durable power supply solutions for various power distribution scenarios.
