Note: 1. The dimensions and weight are subject to change as required. The data in the two tables are subject to the factory documents.
2. For transformers with a rated capacity of 500kva and below, the load loss value above the diagonal line in the table applies to the Dyn11 or Yzn11 connection group, and the load loss value below the diagonal line applies to the Yyn0 connection group.
3. When the average load rate of the transformer is between 35%-40%, the highest operating efficiency can be obtained by using the loss value in the table.
Product Details
250KVA 20kv 400v S11 Oil-immersed Distribution Transformer for IEC / GB Standard Market 1
Product Features:
The S11 series fully sealed oil-immersed power transformer developed and produced by the company has the advantages of low loss,low noise and high efficiency, which can achieve good energy-saving effects and reduce pollution.
Compared with ordinary oil-immersed transformers, fully sealed transformers eliminate the oil conservator. The change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging so as to enhance operational reliability, and maintain normal operation without maintenance.

250KVA 20kv 400v S11 Oil-immersed Distribution Transformer for IEC / GB Standard Market 3
1.The transformer core is laminated with imported cold-rolled silicon steel sheets, which greatly reduces the no-load loss and no-load current. The core is bound to ensure the tightness of the core and reduce noise.
2.High and low voltage windings are made of oxygen-free copper, and low voltage windings of 500kVA and below adopt double-layer cylindrical structure. 630kVA and above adopt double helix or four helix structure, high voltage winding adopts multilayer cylindrical structure.
3.The transformer connection group uses Dyn11 to reduce the impact of harmonics on the power grid and improve the quality of power supply.
4.The transformer is a fully sealed structure, which prolongs the service life, does not require hanging cores and maintenance.
5.The measured noise value is lower than the standard. After this series of transformers have been transported normally, the relevant parts can be installed without core inspection, and they can be put into operation once the acceptance test is qualified.
