The design meets strict international safety standards. It carries recognized certifications for electrical equipment. These ensure compliance in most regions.

Installation is straightforward for trained technicians. The pad-mount design saves space compared to larger substation transformers. It fits well in commercial areas or industrial sites. Connections for the high-voltage cables and low-voltage outputs are clearly designated. Terminals are robust for secure wiring. The transformer arrives ready for connection after basic site preparation. It requires minimal setup before commissioning. Routine maintenance checks keep it running efficiently for years.

Applications of 3500 Kva 34.5 Kv Grounding Transformer Pad-Mounted with 415V & 480V Output Three Phase 50Hz & 60Hz Frequency

This 3500 kVA pad-mounted transformer handles 34.5 kV input. It provides a solidly grounded neutral for the system. This grounding is vital for safety and stable operation. The transformer delivers power at two common low voltages: 415V and 480V. It works reliably with both 50Hz and 60Hz electrical systems. This flexibility makes it suitable for many global applications.

It serves critical roles in electrical distribution networks. You often find it stepping down voltage for industrial parks or large commercial complexes. The unit feeds power reliably to heavy machinery, lighting, and HVAC systems. Its pad-mounted design is important. This means it sits securely on a concrete pad at ground level. This setup is safer and easier to access than pole-mounted units. It saves space too.

Renewable energy projects use this transformer extensively. It connects solar farms or wind turbine arrays to the medium-voltage grid. The transformer adjusts the voltage efficiently. It handles the variable power output common in renewables. The dual voltage outputs (415V and 480V) are a major benefit. Facilities can use the same transformer model for different internal equipment needs. This simplifies inventory and installation.

Industrial facilities rely on its robust grounding capability. This protects sensitive manufacturing equipment from voltage surges and faults. Factories need stable, clean power. This transformer helps provide that. Data centers also utilize these units. They ensure continuous, high-quality power for servers and cooling systems. The 3500 kVA capacity is significant. It supports large power demands effectively.

The ability to operate at both 50Hz and 60Hz is crucial. It allows deployment in diverse international markets. Projects in Europe, Asia, or the Americas can use the same unit. This reduces design complexity and sourcing challenges. The transformer offers a dependable solution for stepping down high voltage safely. It delivers versatile power where it’s needed most.

5 FAQs of 3500 Kva 34.5 Kv Grounding Transformer Pad-Mounted with 415V & 480V Output Three Phase 50Hz & 60Hz Frequency

What does this transformer do?
This unit protects equipment and people. It provides a safe grounding point for 34.5kV systems. It also transforms that high voltage down to usable 415V or 480V power. It feeds machinery and facilities needing three-phase electricity.

What voltages does it handle?
It connects directly to 34.5 kilovolt power lines. Inside, it steps this down. You get two separate low voltage outputs: 415 volts and 480 volts. Both outputs are three-phase. You choose the voltage needed for your specific equipment.

Will it work with 50Hz and 60Hz power?
Yes. The transformer is built for both frequencies. It operates correctly whether your local grid uses 50Hz (common in many countries) or 60Hz (common in North America). You don’t need different models.

Why is it pad-mounted?
Mounting it on a concrete pad keeps it secure and safe outdoors. This design protects the transformer from weather and accidental contact. It saves space inside buildings. Installation and maintenance are simpler outside. The enclosure is tough and lockable.

How does it stay cool?
This is a dry-type transformer. It uses air for cooling. There is no oil inside. This makes it safer and cleaner. It reduces fire risk and avoids messy leaks. Air flows naturally or with fans around the coils to manage heat.
