10KV LEVEL S13-M SERIES OF OIL-IMMERSED FULLY SEALED DISTRIBUTION TRANSFORMER

Description

S13-M series are energy-saving transformers, the iron cores are using high quality high permeability oriented silicon steel sheet, optimized design,making on-load loss ratio is 27％averagely lower than S11 type they are only next to a new gene ration of energy-saving products which are S(B)H15 type amorphous alloy transformers, so they have very high performance-priceratio.of the operational.

Features:

1. Scientific computing tools: the transformer uses advanced electric, magnetic, thermal and mechanical computing software to calculate electro-magnetic field and magnetic flux leakage distributions, to analyze wave processes, and to select reliable insulation margin, thus to guarantee product reliability.

2. Reasonable structural layout: The transformer uses multilevel stepped lap helical structure to reduce the no-load losses and noise. Its core is supported by inside rods,and its winding uses cardboard tubes to enhance short circuits withstand capacity,we also uses baffle plate to direct the oil flow for reduction of winding temperature rise. Heterotypic radiators are applied to improve the cooling centers for reduction of oil temperature rise. All internal insulating parts and metal structural parts have round processed for reduction of partial discharge.

3. Advanced technology: Its core is automatically cut with high precision and few burrs. It works without folding the upper yoke, with surface coated double H curing adhesive and fastened. We have vertical winding machine with digital control tension device. Its active part adopts phase-assembly technology, and the lead is wholly pre-fabricated. Automatic control of Kerosene Vapor-phase drying process is used.

4. Perfect quality guarantee system: The company strictly controls the quality of products according to ISO19001 standard.

5. To meet the client’s needs, we can provide products of other voltage ratios, Vector Groups, and rated capacities, as listed in the table.
