2nd-Generation of SBH15 Series Oil Immersed Amorphous     Alloy Transformer

1Product Brief Introduction

the transformer can replace the Silicon steel core transformer widely used in power distribution outdoor. If a Large number of this type transformer operated in power network system, good Energy-saving effect will be got and atmosphere pollution will be reduced at the same time.

Because adopting fully sealed Structure technology, the insulating oil and insulating medium are not polluted In air, the transformer can be run in a humid environment, so it is the ideal Power distribution equipment widely used in urban and rural power distribution System. this transformer is especially suitable for those areas such as Electric energy shortage region, large load fluctuation region and the place Daily maintenance is operated difficult.

 

2 Characteristics:

Transformer amorphous core adopting the structure of three-phase three column, combined with the invention of the patented technology of 2nd-Generation amorphous transformer, the product Running low noise, high reliability.

the High voltage winding adopts multi-layer cylinder structure, which improves Impulse distribution to the windings.

the low voltage Winding with 200~6300KVA capacity adopts cylinder or screw structure, it is High mechanical strength, balance distribution of ampere-turn and good ability of anti short circuit.

Additional Positioning parts to the body of transformer avoid displacement in Transportation, at the same time, all fasteners install binding nut extra to Ensure fasteners of product are not loose in the long running, meet Requirements  to  transformer no suspended core.

Transformer Adopting vacuum oiling technology

Surface Treatment with degreasing, rust and phosphating then Spray primer and topcoat, transformer Can meet the special requirements of moisture and contamination areas.

Beautiful Appearance, small size and space to installation and maintenance free, it is an Ideal quality product.
