S11 Oil Filled Hermetically Sealed Distribution Transformer
Performance Characteristics
●The no-load loss of this series transformer is reduced by about 30% on average compared with the S9 transformer.
●The low voltage winding with capacity in the range of 630~2000kVA adopts cylinder or spiral structure, high mechanical strength, balanced ampere-turns distribution, and anti-short circuit energy of the product
Good force.
●The body is added with a positioning structure, so that it does not cause displacement during transportation. At the same time, all fasteners are installed with fastening nuts to ensure that the product is in long-term operation
In the process of tight firmware is not loose, full of no core lifting requirements.
●The ripple tank is used in the transformer, the oil storage tank is removed, and the cover and the edge of the box are completely welded or fastened with a bolt, which prolongs the service life of the transformer oil.
●The surface of the product is sprayed with primer and top paint after oil removal, rust removal and phosphating treatment, which can meet the special needs of metallurgy, stonification system and wet and dirty areas
Please.
●Selected components, using a fully sealed transformer tank, according to the standard requirements installed pressure release valve, signal thermometer, gas relay, etc., to ensure the variable pressure
Device safe operation. This series of products have beautiful appearance, small volume, and can reduce the installation area, which is a maintenance-free high-quality product.
