Amorphous alloy oil immersed transformer

Product Details:

Amorphous alloy oil-immersed transformers are highly efficient and energy-saving transformers that utilize amorphous alloy strip as the iron core and transformer oil as the insulation and cooling medium. 

Product Introduction

  Amorphous alloy oil-immersed transformers are highly efficient and energy-saving transformers that utilize amorphous alloy strip as the iron core and transformer oil as the insulation and cooling medium. Here is a detailed introduction:

  I. Core Advantages

  1. Significant Energy Efficiency

  The no-load loss of amorphous alloy iron cores is 70%-80% lower than that of traditional silicon steel transformers. For instance, a 500kVA amorphous alloy transformer has a no-load loss of only 190W, compared to 900W for an S9 silicon steel transformer, demonstrating remarkable energy-saving performance.

  For scenarios with fluctuating loads (e.g., residential communities, commercial buildings), the energy-saving benefits are even more pronounced, significantly reducing long-term operational and maintenance costs.

  2. Excellent Environmental Performance

  Amorphous alloy transformers effectively reduce emissions of harmful gases such as CO, SO₂, and NOₓ, mitigating air pollution and meeting "green product" standards.

  If widely adopted in distribution networks across developing countries like China and India, they could save 25-30 TWh of electricity annually and reduce CO₂ emissions by 20-30 million tons.

  3. Reliable and Stable Operation

  Featuring a fully sealed structure, these transformers delay the aging of transformer oil and insulation paper, enabling maintenance-free operation.

  The low-voltage winding adopts a foil-wound design, offering low losses and strong short-circuit resistance, with an advanced and rational structure.

  The Dyn11 connection group minimizes harmonic impact on the grid, improving power quality.

  4. Economic Advantages

  Although manufacturing costs are approximately 30% higher than traditional transformers, energy-saving benefits recoup the incremental cost within 3-5 years.

  Long-term operation reduces power plant investment and fuel consumption, lowering overall lifecycle costs.

  II. Technical Characteristics

  1. Iron Core Material

  Amorphous alloy is composed of elements such as iron, nickel, cobalt, boron, and carbon, formed through ultra-rapid cooling solidification, resulting in a disordered atomic arrangement.

  With a thickness of just 0.027mm, its resistivity is 3-6 times higher and hardness 5 times greater than silicon steel. However, it is sensitive to stress and requires careful handling during transportation to avoid impacts.

  2. Structural Performance

  Low losses, minimal heat generation, and low temperature rise ensure stable operation.

  Small magnetization power and the absence of structural defects impeding domain wall movement contribute to superior magnetic permeability.

  III. Application Scenarios

  1. Distribution Network Sector

  Suitable for agricultural and urban distribution networks, particularly in scenarios with low loads and fluctuating demands (e.g., seasonal tourist attractions, irrigation areas).

  Can be integrated with switchgear into prefabricated substations for flexible power supply solutions.

  2. Critical and Special Facilities

  Ideal for commercial complexes, high-rise buildings, airports, industrial plants, power stations, oil platforms, subways, and tunnels where power supply stability and fire safety are paramount.

  3. Renewable Energy and Environmental Sectors

  Aligns with national policies on energy conservation and emission reduction, making it an excellent choice for rural grid upgrades and urban infrastructure modernization.

  In coal-to-electricity conversion areas and urban residential communities, it significantly reduces power losses and enhances energy efficiency.

  IV. Market Trends

  1. Policy-Driven Adoption

  With stricter national energy efficiency and environmental regulations, amorphous alloy transformers are gradually replacing high-energy-consuming traditional models, becoming an industry trend.

  2. Technological Advancements

  Manufacturers are enhancing product performance and reliability through design optimizations (e.g., vacuum oil injection to eliminate coil bubbles) and material improvements.

  3. Cost Optimization

  As production scales up and technologies mature, manufacturing costs for amorphous alloy transformers are expected to decline, further strengthening their market competitiveness.
