Three phase pad mounted transformer successfully shipped to Canada

Varelen recently reached another milestone in its journey of delivering top-tier power solutions by successfully shipping a 3000 kVA three-phase pad-mounted transformer to Canada. This project demonstrates Varelen’s ability to deliver innovative, efficient, and reliable power solutions tailored to meet the evolving needs of its global clientele. The Cooper Power series three-phase pad-mounted transformers are designed to be compact, efficient, and environmentally friendly, making them ideal for diverse applications in utility, commercial, and industrial sectors.

Three-Phase Pad-Mounted Transformer

Three-phase pad-mounted transformers are compact, self-contained units designed to step up or step down voltages in utility, industrial, and commercial power distribution systems. Unlike traditional substation transformers, these transformers are enclosed in a tamper-resistant cabinet, making them ideal for outdoor installations in urban or rural settings.

These transformers are particularly useful in underground distribution systems, where aesthetics, safety, and space optimization are critical. The use of advanced dielectric fluids, such as FR3, enhances safety and environmental performance while maintaining high efficiency and reliability.

Core Features of Pad-Mounted Transformers

Varelen’s three-phase pad-mounted transformers come equipped with several innovative features to meet diverse energy requirements:

1. Live-Front or Dead-Front Design

   • Provides flexibility for different system layouts.
   • Enhances safety and accessibility during operations and maintenance.

2. Surge Protection

   • Built-in solutions for critical loads, such as data centers and renewable energy systems.
   • Superior performance under stressful electrical environments.

3. Vacuum Fault Interrupter (VFI)

   • Combines voltage transformation with loop or transformer overcurrent protection.
   • Space-saving and cost-efficient.

4. Renewable Energy Compatibility

   • Ideal for solar photovoltaic generator step-up (GSU) applications.
   • Designed to support the transition to renewable energy systems.

5. Flexible Placement

   • Can be located near or inside buildings to optimize land use and minimize installation costs.

Designed to Withstand All Environmental Hazards

Varelen’s  series pad-mounted transformers are built to endure harsh environmental conditions, 

• Robust Construction

  • Made with durable materials and E-coat technology to prevent corrosion and ensure longevity.

• Regulatory Compliance

  • Meets or exceeds ANSI, NEMA, IEEE, and CSA standards.
  • UL-listed and FM-approved up to 35kV for added reliability.

• Enclosed Connections

  • Fully enclosed designs protect against moisture, dust, and tampering, ensuring optimal performance in adverse conditions.

When to Use a Three-Phase Pad-Mounted Transformer

In an underground primary feeder system,three-phase pad-mounted transformers are an alternative to three-phase substation transformers. three-phase pad-mounted transformers are ideal for a variety of applications:

Lower Land and Installation Expenses
The compact design of a pad-mounted transformer significantly reduces the need for land compared to a traditional substation. This smaller footprint helps lower the costs associated with securing permits and obtaining rights-of-way. Additionally, the self-contained and tamper-resistant structure allows for installation in unsecured locations, eliminating the need for extra fencing or enclosures. This setup also simplifies maintenance access, further reducing operational costs.

Enhanced Visual Appeal
Pad-mounted transformers have a more streamlined and compact design than traditional substations. Their clean, unobtrusive appearance makes them a better choice for locations where aesthetics are a concern, such as urban or residential areas.

Improved Safety Features
Safety is a priority with pad-mounted transformers, which feature tamper-resistant designs that meet or exceed IEEE Std C57.12.28™-2014 security standards. By using underground cable connections and fully enclosed components—especially in dead-front configurations with elbow inserts—these transformers ensure higher safety for both the public and operating personnel. The enclosed design also provides added protection against environmental hazards, ensuring reliable performance in various conditions.

Customized Transformers to Meet Every Need

Varelen understands that no two projects are the same. That’s why  transformers are engineered to order, offering:

• Flexible Configurations

  • Customized to meet unique requirements, including voltage, capacity, and additional features.

• Accessory Options

  • Wide range of accessories for monitoring, protection, and enhanced performance.

• Emergency Stock Availability

  • Quick access to ready-made units for urgent applications.

Sustainability at the Core

Sustainability is at the heart of Varelen’s design philosophy. The use of FR3 fluid in pad-mounted transformers offers several environmental benefits:

• Biodegradability

  • FR3 fluid is non-toxic and biodegradable, reducing environmental impact.

• Fire Safety

  • High-fire-point properties enhance operational safety in sensitive areas.

• Extended Equipment Life

  • Improved thermal performance reduces wear and prolongs the lifespan of transformers.

Varelen also provides mineral oil and alternative fluids to suit customer preferences while adhering to environmental standards.

Conclusion

With a focus on customer-centric innovation, Varelen continues to lead the way in intelligent power management, providing solutions that not only meet but exceed global energy distribution demands. By choosing Varelen, customers can rest assured they are investing in technology that is efficient, environmentally friendly, and built for the future.
