Introduction to Power Distribution Transformers

Transformers play a critical role in power distribution by stepping up or stepping down voltage levels to ensure efficient electricity transmission. Selecting the right transformer depends on factors such as load requirements, environmental conditions, safety regulations, and cost efficiency.

This guide explores the different types of transformers used in power distribution and highlights Junengda Electrical, a leading manufacturer specializing in high-quality power transmission solutions.

Types of Transformers Used in Power Distribution

1. Pole-Mounted Transformers

• Best for: Overhead power distribution in rural and urban areas.
• Key Features:
  • Mounted on utility poles to save ground space.
  • Typically used for 11kV to 400V step-down distribution.
  • Weather-resistant design.

2. Compact Substations

• Best for: Urban and industrial power distribution.
• Key Features:
  • Integrated design with transformers, switchgear, and control systems.
  • Space-saving and easy to install.
  • Used in commercial complexes and residential areas.

3. Power Transformers

• Best for: High-voltage transmission networks (grid stations).
• Key Features:
  • Handles voltages above 33kV.
  • Used in generation plants and substations.
  • High efficiency with minimal energy loss.

4. Oil-Immersed Transformers

• Best for: Heavy-duty industrial applications.
• Key Features:
  • Uses mineral oil for cooling and insulation.
  • Long lifespan and high durability.
  • Suitable for outdoor installations.

5. Pad-Mounted Transformers

• Best for: Underground power distribution.
• Key Features:
  • Installed on concrete pads at ground level.
  • Tamper-proof and safe for public areas.
  • Common in cities with underground cabling.

6. Dry-Type Transformers

• Best for: Indoor and eco-sensitive applications.
• Key Features:
  • No oil, making them fire-resistant.
  • Low maintenance and environmentally friendly.
  • Used in hospitals, schools, and data centers.

7. Distribution Transformers

• Best for: Final voltage step-down to end-users.
• Key Features:
  • Converts 11kV/33kV to 230V/400V.
  • Used in residential and commercial power supply.
  • Available in oil-cooled and dry-type variants.

Key Factors in Choosing a Distribution Transformer

When selecting a transformer, consider:

• Load Capacity (kVA rating)
• Voltage Requirements (input/output levels)
• Cooling Method (oil-immersed vs. dry-type)
• Installation Environment (indoor/outdoor, weather conditions)
• Efficiency & Losses (energy-saving models)
• Compliance with Standards (IEC, IEEE, ANSI)
