Dry-type PV Step-up Transformer for Solar Power Station

Xuzhou Tuojie's Dry-type PV Step-up Transformer for Solar Power Station delivers enterprise-grade performance with capacity ranging from 30KVA to 31,500KVA. Our transformers feature ultra-low partial discharge design, achieving 150% rated load operation under forced-air cooling. Backed by 18 patents and manufactured using over 120 sets of advanced CNC equipment, each unit undergoes strict ISO9001 quality management. With F/H class insulation systems and multi-standard compliance (IEC60076/ANSI/IEEE/GB), our transformers ensure stable voltage conversion from 10-35kV primary to 0.22-1.14kV secondary voltage, perfectly matching modern solar power station requirements.

Why Choose Our Solar Step-up Transformers?

Your solar power station deserves equipment that works as hard as you do. Our transformers are built specifically for photovoltaic applications.

Built for Solar Environments

Solar power production has its own set of problems. Changes in temperature, changing loads, and the outdoors all call for strong tools. These conditions are no problem for our transformers.

The structure of the epoxy resin mould is very resistant to water. It's fine to work when the humidity is 100%. After shutdown, there is no need for pre-drying. This means that your building will have less downtime and make more energy.

Energy Efficiency That Matters

When it comes to solar power, every watt counts. The types in our SCB14 and SCB18 lines are designed to have very low loss. This directly makes your system work better generally.

More power gets to the grid when losses are lower. That means you'll get more money back from your solar investment. The grain-oriented silicon steel core cuts down on no-load losses by a large amount.

Maintenance-Free Operation

You require tools that work reliably even when they don't need constant care. Our dry-type system doesn't need any oil upkeep at all.

No oil changes. No checking for leaks. No worries about the earth. Your prices for repairs go down by a lot. The flame-retardant and self-extinguishing materials keep everyone safe without any help.

Key Advantages for Solar Applications

Superior Load Adaptability

Solar generation varies throughout the day. Our transformers adapt smoothly to these load changes. The intelligent temperature monitoring system adjusts cooling automatically.

During peak generation hours, forced-air cooling enables 150% rated load operation. This flexibility maximizes your power output when the sun shines brightest.

Safety First Design

Your facility's safety is non-negotiable. Our transformers can be installed directly at the load center. The non-flammable, pollution-free construction eliminates fire risks.

Low partial discharge levels protect your equipment and extend service life. The smart temperature protection system prevents overheating automatically.

Customization for Your Project

Every solar installation is unique. We offer full customization options:

  • Capacity tailored to your generation output
  • Voltage ratios matching your grid connection requirements
  • Connection groups (Dyn11, Yyn0, Yd11) per local standards
  • IP protection ratings for indoor or outdoor installation
  • Special altitude and climate considerations

Our 15 senior engineers and technical team work with you to design the perfect solution.

FAQ

Q: What insulation class do your solar transformers use?

Our transformers feature Class F or H insulation systems. Temperature rise is controlled within 100K for Class F and 125K for Class H, per IEC standards. This ensures excellent thermal performance and long service life in solar applications.

Q: How do dry-type transformers benefit solar installations?

They're flame retardant, self-extinguishing, and completely pollution-free. The moisture resistance is outstanding, operating normally at 100% humidity. Low noise levels make them suitable for installations near residential areas. No oil means no environmental liability.

Q: Can you customize transformers for different grid standards?

Absolutely. We customize voltage ratios, capacity, short-circuit impedance, tapping range, and connection groups. Whether you're connecting to European, American, Asian, or other grid standards, we adapt our design to match your requirements perfectly.

Q: What cooling options work best for solar applications?

We offer both AN (air natural) and AF (air forced) cooling. For installations with variable loads, AF cooling provides flexibility. The forced-air system enables 150% overload capacity during peak generation periods while maintaining safe operating temperatures.

Q: How long is the typical delivery time?

Standard configurations ship within 4-6 weeks. Custom designs require 6-10 weeks depending on specifications. Our production scheduling prioritizes solar projects to minimize your installation timeline. We'll provide a precise schedule once we understand your requirements.

Q: What support do you provide after installation?

We offer complete technical documentation, installation guidance, and commissioning support. Our team assists with startup procedures and performance verification. For ongoing operation, we provide remote technical consultation and spare parts availability.
