Custom Three Phase Transformer Manufacturer

By choosing a Leightner custom three-phase power transformer, you can ensure that the transformer is optimized for your specific power requirements, space constraints, and operational needs, maximizing the benefits for your particular application.

Power distribution and electrical systems that demand efficient distribution and high-power transmission capabilities are perfect for three-phase power transformers. Compared to other power transformer configurations, three-phase transformers are more flexible, lighter, and cheaper at greater power configurations.

Advantages of Custom Three Phase Transformers

Three-phase power transformers offer numerous advantages over single-phase transformers, making them an excellent choice for many applications, especially in industrial and commercial settings. Here are the key benefits of using a custom three-phase power transformer:

  • Increased Power Capacity and Efficiency
  • Improved Power Quality and Stability
  • Space and Cost Efficiency
  • Versatility and Scalability
  • Enhanced Reliability and Maintenance

Our Manufacturing Process For 3 Phase Transformers

The manufacturing process begins with the core, which is typically made from silicon steel sheets, specifically Cold Rolled Grain Oriented (CRGO) steel. The core is designed with a three-limb configuration, and the sheets are cut according to the required specifications. The core sheets are then:

  • Coated with inorganic insulation
  • Assembled using mitered joints between limb and yoke plates
  • Banded with fiber-glass tape to reduce noise and maintain tightness
  • Treated with a corrosion-resistant coating

The winding of the coils is a critical step in transformer manufacturing:

  • Coils are wound using copper magnetic wire or continuously transposed conductor
  • Circular concentric windings are commonly used for most transformers
  • The winding type is selected based on voltage requirements and application

Insulation is crucial for the transformer’s performance and longevity:

  • High-density pressboard is used to create spacers and insulation cylinders
  • Coil sizing is checked and adjusted
  • Complete winding insulation packages are introduced

The core and coil assembly process involves:

  • Joining exposed core edges with epoxy resin
  • Lowering coils over the core
  • Securing windings with tie rods for support against axial forces
  • Providing additional support for leads and busbars

The assembled transformer undergoes further processing:

  • The core and coil assembly is dried using a vapor phase cycle approach
  • Final components such as the conservatory, radiators, pumps, and fans are installed

Applications for Three Phase Power Transformers

Three-phase transformers play a crucial role in various industrial applications due to their efficiency, power capacity, and versatility. Here are the main applications of three-phase transformers in industries:

  • Chemical and Petrochemical Processing Plants
  • Mining and Construction
  • Transportation Infrastructure
  • Commercial Buildings
  • Renewable Energy Systems
  • Data Centers
  • Industrial Manufacturing
  • As well as many other industries
