Core Advantages of the Three-phase Oil Filled Power Transformer
1.Exceptional Short-circuit Resistance and Structural Reliability
The Three-phase Oil Filled Power Transformer is designed with high-strength structures and premium cold-rolled silicon steel materials, ensuring stable operation even under sudden short circuits, overloads, or extreme conditions. Its superior mechanical strength and impact resistance can withstand shocks such as earthquakes or voltage fluctuations, safeguarding the security of power systems. It is especially suitable for large-scale industrial applications and high-risk scenarios.
2.Highly Efficient and Low-loss Design
This oil-immersed transformer optimizes its winding and magnetic circuit design, significantly reducing copper losses, iron losses, and load losses, achieving international leading energy efficiency standards. Its low-loss characteristics not only minimize energy waste but also lower long-term operational costs, aligning with global green power standards and helping users achieve low-carbon goals.
3.Quiet Operation and Low Partial Discharge Performance
The transformer employs advanced noise reduction technology, resulting in operating noise levels below industry averages, making it ideal for noise-sensitive environments. Additionally, partial discharge levels are strictly controlled within ultra-low ranges (e.g., ≤10pC), drastically reducing electromagnetic interference and ensuring the purity of power transmission and extended equipment lifespan.
4.High Sealing Performance and Long Service Life
Featuring a fully sealed oil tank design combined with high-quality epoxy resin sealing components, it effectively isolates external moisture, contaminants, and oxygen, preventing insulation oil aging and significantly reducing maintenance needs. Its sealing performance and anti-corrosion structure ensure a service life exceeding 30 years, lowering lifecycle costs.
5.International Certification and Wide Applicability
Strictly manufactured according to GB1094, IEC, and UL standards, this transformer is compatible with mainstream global power system voltage levels (such as 110kV). With capacities ranging from 6,300kVA to 42,200kVA, it flexibly adapts to various high-load scenarios including main transformers in power plants, large grid transmission and distribution, mining and metallurgy, and rail transportation, meeting the reliability requirements of large-scale power projects.
