Electric Oil-Immersed Low Loss Power Transformer
Introduction
Electric oil immersed transformers are designed to enhance energy efficiency and reduce operational costs in power distribution systems. These transformers are widely used in power generation, transmission, and distribution, as well as in industrial and commercial settings. They offer significant improvements in energy efficiency, reduced environmental impact, and enhanced reliability.
Key Features
Energy Efficiency
-
Reduced No-Load Losses: The S13 series transformers achieve a 30% reduction in no-load losses compared to the S11 series, significantly contributing to energy conservation and reduced operational costs
-
High Efficiency: The S22 series transformers offer even higher efficiency, with a first-class energy efficiency index and an efficiency as high as 98%.
Advanced Materials and Design
-
High-Quality Core Materials: The core is made of high-quality cold-rolled grain-oriented silicon steel sheets, which are known for their superior magnetic properties. This material choice results in lower core losses and enhanced energy efficiency.
-
Innovative Joint Structure: The transformers feature a multi-step progressive full-lap joint structure, which not only strengthens the core but also optimizes the magnetic flux path, leading to improved performance and durability.
Noise Reduction
Outdoor Durability
-
Robust Design: The transformers are designed to withstand harsh environmental conditions, ensuring reliable outdoor use. The fully sealed design prevents contact with the air, ensuring long-term reliability even in humid environments.
Safety Mechanisms
Technical Specifications
Core Design
-
Innovative Lamination: The core is made of high-quality cold-rolled grain-oriented silicon steel sheets, with a 45° full oblique shearing on the transverse shear line. The core column and yoke joint are in a five-step laminated structure, improving the magnetic field distribution and reducing energy consumption.
Winding
-
Compact Foil Winding: The winding is made of copper foil, ensuring uniform distribution of operating current and improving the balance of the ampoule. The axial short-circuit force of the transformer is small, simplifying the winding pressing device and improving the short-circuit resistance of the transformer.
Tank
-
Corrugated and Sealed: The fuel tank uses a corrugated design, made of high-quality cold-rolled steel sheet. The corrugated sheet is formed by a transformer corrugated oil tank automatic production line and is protected by argon gas. This design has the advantages of strong pressure, good elastic deformation, high heat dissipation coefficient, and no leakage during operation.

The energy efficiency level of oil-immersed transformers is divided according to their no-load loss and load loss, and is usually divided into level 1, level 2 and level 3, among which level 1 has the highest energy efficiency and level 3 has the lowest energy efficiency. The following is a method to distinguish the energy efficiency level of oil-immersed transformers:
1. Check the model identification
2. Refer to national standards
3. Check the nameplate information
4. Specific requirements for energy efficiency level
5. Other considerations
When selecting a transformer, it is necessary to comprehensively consider the energy efficiency level, operating cost and initial investment cost.
The above method can effectively distinguish the energy efficiency level of oil-immersed transformers and ensure that the most suitable equipment is selected in actual applications.
