S(B)H15-M Series Sealed Amorphous Alloy electrical Distribution Transformer Transformer


Amorphous alloy transformer is a low-loss and high-efficiency power transformer with iron-based amorphous metal as the iron core. The iron loss (ie no-load loss) of amorphous alloy transformers is 70-80% lower than that traditional transformers which generally use silicon steel as the iron core. It is an ideal low-loss energy-saving transformer at present. Because of low losses amorphous alloy transformers generate less heat .The temperature rise is low and the running performance will be very stable.


It can be widely used in high-rise buildings, commercial centers, subways, airport, stations, industrial and mining enterprises, drilling platforms, oil production platforms; especially suitable for flammable, explosive and other places with high anti-inflammatory requirements and harsh environments, and can also be used in residential areas , Commercial streets, industrial and mining enterprises and rural power and lighting.

Structural features:

  • 01 Low loss, energy saving and high electricity efficiency.No-load loss is lowered by 70% compared with the traditional transformers.
  • 02.Low noise. Greatly reducing the noice class by using three- column amorphous cores.
  • 03 Maintenance free and no pollution. Low electricity consumption can reduce the emission of SO2CO2, and decrease environmental pollution and greenhouse effect.
  • 04 Good heat dissipation, strong overload capacity, and can be overloaded by 50% under air cooling
  • 05 Safe, non-flammable and fireproof can be installed directly in the load center
  • 06 No oil change is required under normal operation, which greatly reduces transformer maintenance costs and extends service life.
  • 07 Small size, light weight, stable structure, strong resistance to lightning impact, high mechanical strength, resistance to temperature changes and strong short-circuit resistance.
  • Iron core1.The amorphous alloy iron chip is extremely thin with 0.025mm. Lamination coefficient is low with 0.86. it is a new type of energy-saving material with iron, boron and other elements as the original subject. It adopt rapid Special processes such as cooling and solidification make the atomic arrangement of the substance appear as a disordered alloy. Its physical state is that the metal atoms are disordered and amorphous. It is completely different from the crystal structure of silicon steel and quite easy to be magnetized. Reduce the no-load loss of the transformer;


    1. The transformer core is usually rolled into a three-phase five-pillar structure with an amorphous alloy, which makes the height of the transformer lower than three-phase three-pillar. The circumference of the iron core is rectangular, and the lower yoke can be opened to facilitate the suit of the coil.

    2. Not only low-capacity windings using copper conductors, but also low-voltage windings generally use a cylindrical structure wound with copper foil. High-voltage windings use a multi-layer cylindrical structure to balance the ampere-turn distribution of the windings and minimize magnetic leakage.


    The body assembly, oil tank structure, protection device and other aspects are similar to the fully sealed oil-immersed distribution transformer. It also uses a non-suspended structure, adopts vacuum drying, vacuum oil filtering and oil injection processes.It uses a corrugated oil tank and no oil storage cabinet.
