Product Groups

Power Transformers

Power transformers are essential components in the field of electricity, primarily used for high-voltage energy transmission. Designed for capacities ranging in several megavolt-amperes, these transformers ensure efficient and reliable management of electrical loads in industrial settings. With their robust construction and use of oil as an insulator and cooling system, they provide excellent durability and thermal performance under extreme environmental conditions. This type of transformer is crucial for long-distance energy distribution, ensuring a continuous and stable power supply.

Specifications:

  • Capacity: Typically several megavolts (MV).
  • Application: Ideal for industrial use and large-scale energy distribution.
  • Insulation: Often oil-filled or dry-type.

Key Advantages:

  • Reliability and strength suited for demanding environments.
  • Enables efficient management of high electrical loads.
  • Long lifespan with regular maintenance.

Oil-Immersed Distribution Transformers

Oil-immersed distribution transformers are a reliable solution for medium and low-voltage electricity distribution. With capacities up to 50 MVA, these transformers are renowned for their excellent heat transfer, which extends service life and improves efficiency. Their robust design allows them to withstand outdoor environmental conditions while keeping maintenance costs low. Thanks to their ability to absorb load fluctuations, they ensure a stable and safe power supply for electrical distribution networks, making them essential for operational reliability.

Specifications:

  • Application: Designed for medium and low-voltage energy distribution.
  • Insulation: Use oil as both an insulator and coolant.
  • Capacity: Varies by need, generally up to 50 MVA.

Key Advantages:

  • Excellent heat dissipation, extending transformer lifespan.
  • Durable design suitable for outdoor environments.
  • Low maintenance costs.

Three-Phase Transformer

The three-phase transformer is a crucial component of modern electrical systems, primarily used in industrial applications to balance energy distribution. Made up of three windings, it enables efficient load management and minimizes energy losses. This type of transformer enhances energy efficiency, which is especially important in industrial environments where reducing operational costs is critical. By delivering continuous and stable power, the three-phase transformer not only ensures equipment stability but also optimizes the overall performance of the electrical systems in use.

Specifications:

  • Configuration: Composed of three windings, ideal for balanced loads.
  • Application: Mainly used in industrial settings and for long-distance power transmission.

Key Advantages:

  • Improves energy efficiency compared to single-phase systems.
  • Provides proper load balancing, reducing losses.
  • Enables continuous and stable energy distribution.

Single-Phase Transformers

Single-phase transformers are generally used for less demanding yet equally vital applications in residential and commercial settings. With capacities ranging from a few VA up to 1 MVA, they are ideal for supplying low to medium electrical loads. Their simple and compact design allows for quick and cost-effective installation, while meeting the electrical distribution needs of homes, offices, and small industries. Single-phase transformers are known for their reliable operation and low operating costs, making them a smart choice for systems with limited energy demands.

Specifications:

  • Configuration: One primary and one secondary winding.
  • Application: Mainly used in residential or small industrial applications.

Key Advantages:

  • Compact and easy to install.
  • Less expensive than three-phase transformers for specific uses.
  • Ideal for simple circuits requiring basic electrical power.

Dry-Type Transformers

Dry-type transformers are recognized for their safety and efficiency, especially in environments where fire risks must be minimized. Insulated with solid materials such as epoxy resin, they do not require oil, thus eliminating the risk of leakage. Commonly used in sensitive applications such as hospitals, data centers, or industrial facilities, these transformers offer excellent durability while requiring minimal maintenance. Thanks to their environmentally friendly design, dry-type transformers provide a safe and robust option to meet the energy demands of modern installations.

These descriptions aim to provide a clear understanding of the functions and benefits of each transformer type offered, while highlighting their importance in the energy sector.

  • Insulation: Use solid materials instead of liquid for insulation.
  • Application: Ideal for environments with high fire risk or requiring strict environmental standards.

Key Advantages:

  • No risk of oil leakage, making them safer in various environments.
  • Less environmental impact.
  • Low maintenance needs and more durable in some environments.
