Amorphous Core Oil Immersed Transformer

The Amorphous Core Oil Immersed Transformer is an energy-efficient distribution transformer designed to significantly reduce no-load losses during long-term operation.

Unlike conventional transformers using grain-oriented silicon steel cores, this transformer adopts high-performance amorphous alloy core material, which provides significantly lower core loss and no-load power consumption.

It is particularly suitable for applications where transformers remain energized for long periods, especially under low or variable load conditions.

By reducing energy losses that occur continuously while the transformer is energized, the amorphous core design can help customers achieve lower lifetime energy consumption and operating costs.

Basic Info.

Advanced Amorphous Alloy Core

The transformer uses high-performance amorphous alloy as the core material instead of conventional grain-oriented silicon steel.

The unique amorphous metal structure provides excellent magnetic characteristics and significantly reduces core loss, making it particularly suitable for distribution systems requiring high energy efficiency.

Designed for Long-Term Energy Saving

Unlike load losses, no-load losses occur whenever the transformer is energized, regardless of whether the transformer is heavily loaded.

Therefore, the low no-load loss characteristic of an amorphous core transformer provides significant benefits in applications with:

· Long daily operating hours

· Continuous energization

· Low average load rates

· Significant day/night load variations

·Long service life requirements

This makes the transformer a suitable solution for energy-saving distribution systems and grid modernization projects.

When Should You Choose an Amorphous Core Transformer?

Amorphous Core Oil Immersed Transformer is particularly suitable when:

· The transformer operates 24 hours a day or for long periods

· The transformer remains energized even during low-load periods

· The average load rate is relatively low

· The load varies significantly between peak and off-peak periods

· The project has strict energy-efficiency requirements

· Long-term operating cost is an important consideration

· The transformer is expected to operate for many years

Typical Examples

A transformer serving a commercial building, industrial park or distribution network may remain energized throughout the day while the actual load changes significantly.

In such applications, reducing no-load loss can provide continuous energy-saving benefits over the transformer's service life.

Core Advantages

Ultra-Low No-Load Loss

The amorphous alloy core significantly reduces no-load loss compared with conventional silicon steel core designs, helping reduce energy consumption during long-term energization.

Excellent Energy-Saving Performance

Particularly advantageous for distribution systems with long operating hours and low or variable load rates.

Low No-Load Current

The optimized amorphous core design helps reduce magnetizing current and improve overall operating efficiency.

Stable Long-Term Operation

Optimized core, winding and insulation designs provide reliable performance for continuous distribution applications.

Lower Lifetime Operating Cost

Although the initial investment may be higher than that of a conventional transformer, lower no-load losses can help reduce electricity consumption throughout the transformer's operating life.

Flexible Project Customization

Capacity, voltage ratio, frequency, cooling configuration, protection accessories and enclosure or anti-corrosion requirements can be customized according to project specifications and local standards.
