1. The transformer core is stacked by imported high-quality cold-rolled silicon steel sheet, which reduces no-load loss and no-load current greatly, and makes the core bound to ensure compactness of the core and reduce noise.

2. High-low voltage winding is wound with oxygen-free cooper, low-voltage winding of 500kVA and below adopts double layer cylinder structure, that of 630kVA and above adopts double helix and four helix structure, and high-voltage winding adopts multilayer cylinder structure.

3. Transformer winding connection adopts Dyn11 to reduce influences of harmonic wave on the power grid and improve power supply quality.

4. The transformer is of full-sealed structure to prolong the shelf life and avoid suspended core use and maintenance.

5. The measured noise level is below the standard.

No suspended-core inspection is needed for this series of transformer after normal transportation and relevant unloading parts can be installed immediately, test for acceptance items shall be performed and it can be put into operation after passing the test.
