Amorphous Alloy Dry Type Transformer

TAILI Silent SCBH15 Amorphous Alloy Dry Type Transformer is a perfect combination of an amorphous alloy core and a resin-insulated dry-type transformer. It is a new type of energy-saving transformer. It has the energy-saving performance of an amorphous alloy core, while keeping all the features of a resin-insulated dry-type transformer.


Our amorphous core transformer (amorphous metal dry-type transformer) is designed to significantly reduce energy loss in power distribution systems. By using advanced amorphous alloy core materials, the transformer achieves much lower no-load loss compared with conventional silicon steel core transformers, making it an ideal choice for projects focusing on energy efficiency and long-term operating cost reduction.


Unlike traditional transformers, the amorphous metal structure minimizes magnetic hysteresis loss, helping improve overall system efficiency, especially in applications where the transformer remains energized for extended periods.

Lower No-Load Loss for Continuous Operation

A Silent Dry Type Amorphous Core Transformer continues to generate core loss whenever it is energized, even when the connected load is low. The amorphous alloy core has lower hysteresis and eddy-current loss than a conventional silicon-steel core, helping reduce continuous no-load energy consumption.

This makes the SCBH15 amorphous alloy dry-type transformer suitable for facilities that operate 24 hours a day or spend long periods under light and medium loads.

Exact energy savings must be calculated using transformers of the same capacity, voltage ratio, load profile and test standard.


Features of Silent Dry Type Amorphous Core Transformer

1. Low partial discharge and long service life.

2. No oil, no pollution, flame-retardant and self-extinguishing.

3. Easy installation, no debugging needed, maintenance-free, low operating cost.

4. Equipped with a complete temperature protection and control system for safe operation.

5. Coils are resin-cast for high mechanical strength, improving short-circuit withstand capability.

6. Excellent moisture and corrosion resistance—ideal for harsh environments. After shutdown, it can be put back into service without drying.

7. High energy efficiency: It reduces no-load loss by about 60% and no-load current by about 60% compared with SCB10 transformers of the same capacity.

Why Choose an SCBH15 Amorphous Alloy Dry Type Transformer?

Amorphous Alloy Core

Thin amorphous alloy strips reduce magnetic core loss. The core support structure is designed to control vibration and maintain mechanical stability.

Resin-Insulated Windings

The windings use copper wire or foil with insulation and mechanical reinforcement. Resin processing helps provide dielectric strength, moisture resistance and short-circuit withstand capability.

AN or AF Cooling

Natural air cooling is available for standard operation. Forced-air cooling can be specified when additional thermal capacity is required. Any temporary capacity increase under AF cooling must be confirmed in the approved rating data.

Oil-Free Indoor Installation

The dry-type structure contains no transformer oil, making it suitable for indoor locations where fire safety, cleanliness and reduced oil-related maintenance are important.


Applications of Silent Dry Type Amorphous Core Transformer


This amorphous alloy dry-type transformer is widely used in projects that require both safety and energy efficiency:

  • ·   Industrial manufacturing plants

  • ·   Commercial buildings and office complexes

  • ·   Data centers and IT infrastructure

  • ·   Hospitals and public facilities

  • ·   Urban power distribution systems

  • ·   Energy-saving retrofit projects

  • ·   Indoor substations and distribution rooms


Amorphous Alloy Dry Type vs. Conventional Dry Type Transformer


The main difference is the magnetic core. An amorphous alloy core uses thin metal ribbon with a non-crystalline structure; a conventional core uses laminated crystalline silicon steel. The amorphous material's magnetic properties and thin ribbon construction help reduce hysteresis and eddy-current losses.


This primarily benefits no-load loss, which continues while the transformer is energized. Load loss also depends on winding design, current and temperature, so both loss components should be compared when selecting a transformer.

Purchase decisionEvaluate additional installed cost against operating savingsEvaluate the complete quoted design and lifecycle cost

Both designs can serve indoor, oil-free distribution. Compare units with the same capacity, voltage ratio, frequency and relevant test conditions. Our Cast Resin Dry Type Transformer range provides another product route for project comparison.
