China S22-M Oil-Immersed Transformer 35 Kv 2500 Kva - Industrial-Grade Power Transmission Suppliers & Factory
Product Application
Application of High Magnetic Flux Oriented Silicon Steel Sheets
The core magnetic path of the transformer is made of high magnetic permeability oriented silicon steel sheets. Compared with traditional silicon steel sheets, its magnetic permeability is increased by more than 15%, and the iron loss value is reduced by 20% to 30%. This material is processed through a special grain orientation optimization process, which makes the magnetic domains more orderly, effectively reducing the hysteresis loss and eddy current loss during the alternating magnetic field process.
Selection of Environmental-Friendly Insulating Materials
The transformer is equipped with environmentally friendly insulating oil and insulating paper. The insulating oil is made of natural esters or synthetic esters, which are environmentally friendly. Compared to traditional mineral insulating oil, it is biodegradable and will not cause pollution to the soil or water sources if it leaks, thus conforming to the concept of green power development.
High-Strength Metal Structural Components
The structural components such as transformer oil tanks and clamps are made of high-strength cold-rolled steel plates. They are formed through CNC stamping and welding. The yield strength of the material reaches over 345 MPa. Compared with ordinary steel plates, the anti-deformation ability has been enhanced by 40%, effectively resisting external force impacts during transportation and installation.
Full Inclined Joint Stacking Process of the Core
The transformer core adopts the full inclined joint stacking process. Compared with the traditional direct joint process, the magnetic resistance at the joint is reduced by more than 60%, effectively reducing the leakage magnetic loss and noise at the joint. During the stacking process, a special positioning tool is used to ensure the flatness and verticality of the core laminations, and the gap between the laminations is controlled within 0.05mm, ensuring uniform magnetic permeability of the core.
