Product Description
Amorphous alloy transformer is a type of transformer that uses amorphous metal alloy as the core material instead of traditional silicon steel. Amorphous metal alloys have unique magnetic properties, which make them more efficient and energy-saving compared to traditional materials such as silicon steel. In addition, the dry type design eliminates the need for oil or other cooling agents, making it more environmentally friendly and requiring less maintenance. The use of this type of transformer can help reduce energy consumption and carbon emissions in power distribution systems.
The energy-saving advantages of amorphous alloy transformers are particularly prominent in the following scenarios:
Distribution room/substation: 10kV/20kV
oil-immersed or
dry-type distribution transformers.
Places with high energy-saving requirements:Data centers, hospitals, schools, large commercial complexes, etc.
Renewable energy field:Step-up transformers for
photovoltaic power stations and wind farms (especially box transformers), using their low no-load loss to adapt to fluctuations in power generation.
Equipment with long operating time and low load rate:Transformers for some industrial equipment.

Description about Power Distribution Transformer for Amorphous Aolly Core
A dry type transformer, also known as an air-cooled transformer, is a type of transformer that utilizes air or gas instead of liquid (such as oil) for insulation and cooling purposes. This transformer design does not immerse its core and windings in insulating oil, making it distinct from oil-filled transformers.
Types of Dry Type Transformers:
- Cast Resin Dry Type Transformer (CRT):
- Uses epoxy resin to encapsulate windings, protecting them from moisture, dust, corrosion, and other environmental factors.
- Suitable for high humidity areas, indoor installations, and fire-risk areas due to its non-hygroscopic, non-inflammable, and maintenance-free nature.
- Available in ratings from 25 kVA to 12,500 kVA, with an insulation class of F (90°C temperature rise).
- Vacuum Pressure Impregnated Transformer (VPI):
- Impregnates windings with class H polyester resin under vacuum and pressure, eliminating air gaps or voids in the insulation.
- Enhances mechanical strength, dielectric strength, and thermal stability.
- Suitable for outdoor installations, seismic events, and temperature fluctuations due to its robust construction, moisture-resistant enclosure, and low thermal expansion coefficient.
Pearl Electric, an experienced transformer manufacturer since 1958, design and produce various cast resin dry type transformer for different application include rectification transformer, marine/offshore oil platform transformer, rectification traction transformer, Transformer for electrified railway station, Rectification excitation transformer etc.
