Product Details

SBH15 Series Amorphous Alloy Oil-immersed Transformer

SBH15 series amorphous transformer is a low loss, high energy efficiency oil-immersed transformer. The iron core of this product is wound from amorphous alloystrip.

Its no-load loss is more than 70%,lower than that of traditional transformers using silicon steel sheets as iron cores. It is a new generation of energy-saving, safe, green and environmentally friendly high-tech products.

And it can replace ordinary oil-immersed transformers, and is mainly suitable for high-rise buildings, commercial centers, infrastructure, industrial and mining enterprises, power plants, etc.

Standard：IEC60076-1, IEC60076-2, IEC60076-3, IEC60076-5, IEC60076-10.

Standard

7. Where to use: indoors or outdoors.

Features

1. The product has the characteristics of high efficiency, low loss, low noise, etc.
2. High mechanical strength, balanced ampere-turn distribution, and strong short-circuit resistance.
3. Low no-load and load loss.
4. Small size, reliable operation, long service life, and maintenance free.

Structure

■ Iron core:

● The iron core is made of high-quality, high-performance, high-permeability silicon steel sheet, with low no-load loss.

■ Other configuration:

● Equipped with and relief valve,signal thermometer, gas relay, ensures the safe operation of the transformer.

■ Positioning structure:

● The product body has added a positioning structure to prevent displacement during transportation, and all fasteners are equipped with fastening nuts to ensure that the fasteners do not loosen during long-term operation of the product.

■ Fully sealed structure:

● The product is a fully sealed structure. The vacuum oil filling process is used for

the transformer packaging, which completely removes the moisture of the transformer,

ensures the isolation of the transformer oil from the outside air, prevents

the aging of the oil, and improves the operation reliability of the transformer.

■ Oil tank:

● The transformer oil tank is composed of corrugated walls, The surface is sprayed

with dust and the paint film is firm,With cooling function,The elasticity

of corrugated heat sink can compensate for the volume change of transformer

oil caused by temperature rise and fall, so there is no oil conservator

in the fully sealed transformer, reducing the overall height of the transformer.

Note 1 :for transformers with rated capacity of 500kVA and below,the load loss values above the diagonal line in the table are applicable to the Dyn11 or Yzn11 coupling group,and the load loss values below the diagonal line are applicable to theYyn0 coupling

group.

Note 2:when the average annual load rate of the transformer is belween 35% and 40%, the maximum operating eficiency can be obtained by using the loss value in the table.
