S13 Oil Immersed Transformer

Product Details: S11/13-M Series Fully Sealed Oil-Immersed Power Transformer

Product Features

• The transformer core is made from imported high-quality cold-rolled silicon steel sheets, which significantly reduce no-load loss and no-load current.
• The core is tightly tied to ensure compactness, reducing noise and enhancing performance.
• High and low voltage windings are wound with oxygen-free copper.
• Low voltage windings for 500kVA and below use a double-layer cylindrical structure, while those for 630kVA and above use a double-helix or four-helix structure.
• High voltage windings use a multi-layer cylindrical structure, ensuring robustness and reliability.

Optimized Connection Group:

• The transformer connection group adopts Dyn11, which reduces the impact of harmonics on the power grid and improves power supply quality.

• The transformer features a fully sealed structure, extending its service life and eliminating the need for routine maintenance such as lifting the core.
• This design ensures long-term reliability and reduces the total cost of ownership.

• The measured noise values are below standard levels, making the transformer suitable for urban and residential areas where noise pollution is a concern.
