Energy Efficient Dry-type Transformer for Photovoltaic

Energy Efficient Dry-type Transformer for Photovoltaic Systems

When you're building or upgrading a photovoltaic power station, choosing the right transformer matters. Our Energy Efficient Dry-type Transformer for Photovoltaic applications combines advanced resin insulation technology with proven reliability. These transformers are up to 30% more energy efficient than regular ones, with capacities between 30KVA and 31,500KVA and efficiency rates up to SCB18 standard. Each unit goes through strict quality control, which is backed by our 18 patents and more than 20 years of manufacturing experience. Our technical team of 15 senior engineers makes sure that every transformer meets international standards and works well for your solar projects without any problems.

Why Your Solar Project Needs the Right Transformer?

Inverters change DC power from photovoltaic systems to AC power. The transformer you need must be able to handle these special features without any problems.

Standard tanks that are filled with oil aren't good for solar setups. They need to be fixed up on a daily basis and are a fire risk near sensitive equipment.

That equation is different with our dry type answer. You get steady performance without the risks that come with oil.

The design, which is protected with resin, can handle tough weather. Your transformer works in both hot and wet places, like the desert and the coast.

Key Features That Make a Difference

Superior Energy Efficiency

When it comes to green energy projects, every watt counts. No-load losses are kept to a minimum by our improved core design. Eddy currents are greatly reduced by high-grade grain-oriented silicon steel.

As a result? Lower costs of doing business and a faster return on your investment.

Built for Photovoltaic Conditions

During the day, solar production changes. These changes in load don't hurt the performance of our transformers.

Smart temperature tracking keeps things from getting too hot during busy work times. If you need to, you can even run at 150% of your rated capacity with forced air cooling.

True Maintenance-Free Operation

With dry-type design, you don't have to test for oil or change it. There are no oil leaks. No risks of infection.

The plastic covering keeps dust and water away from the windings. Your transformer works fine even when there is 100% humidity.

You can restart right away after shutting down. No need to dry it first.

Flexible Customization Options

Every solar farm has unique requirements. We customize:

• Voltage levels from 10kV to 35kV primary
• Capacity selections across our full range
• Vector groups (Dyn11, Yyn0, Yd11)
• Altitude and temperature specifications
• Special interfaces for your monitoring systems

Your Energy Efficient Dry-type Transformer for Photovoltaic installations gets configured exactly as you need.

Technical Specifications

Proven Performance in Real Projects

We've delivered transformers for major installations across multiple sectors.

At GCL Photovoltaic Industrial Park, our units handle the complete power distribution requirements. The project was completed ahead of schedule with zero defects.

Our experience extends beyond photovoltaic applications. From Xuzhou Rail Transit to XCMG Group factory upgrades, we've proven our reliability in demanding conditions.

Each project benefits from our comprehensive quality management system. We follow ISO9001 standards from raw material inspection through final delivery.

Safety and Environmental Benefits

Safety from fire is very important near solar generators and control systems. Our product facilities are naturally resistant to fire.

The plastic shielding can put out fires on its own. There are no harmful gases released during processing. You don't need any special fire control systems to put units right at load centres.

This flexibility cuts down on building costs and room needs by a large amount.

Electronics that are sensitive are kept safe by low partial discharge levels. The electricity where your tracking tools and inverters work is clean.

Manufacturing Excellence Behind Every Unit

Our production facility houses over 120 sets of advanced equipment. CNC automatic winding machines ensure precise coil construction.

Microcomputer-controlled gradient curing furnaces optimize resin casting. The result is uniform insulation without voids or weak points.

Before any transformer leaves our factory, it undergoes comprehensive testing:

• No-load and load loss measurements
• Temperature rise verification
• Partial discharge testing
• Dielectric strength validation
• Sound level assessment

We implement "zero defects" philosophy across every production stage. Only units meeting all specifications reach your site.

FAQ

Q: What makes your transformers specifically suitable for photovoltaic applications?

Our units are designed to handle the changing loads that come with solar systems. With its improved core design, the motor stays efficient over a wide range of loads. During times of high output, intelligent temperature control keeps the heat in check. Solar projects last for 25 years or more, and their maintenance-free design lowers their running costs over that time.

Q: What insulation class do you offer for photovoltaic transformers?

We offer soundproofing solutions for Class F and Class H. IEC rules say that Class F keeps temperature rise to 100K and Class H lets it reach 125K. In challenging photovoltaic settings, both choices are very reliable and last a long time.

Q: Can these transformers operate outdoors in extreme conditions?

Of course. From -40°C to +40°C and up to 95% humidity, our dry-type transformers work consistently. For outdoor setups, we can change the IP protection grades to fit your needs. The moisture-resistant plastic protection works well near the coast, in the desert, and up to 4,000 meters above sea level.

Q: How do I specify the right capacity for my solar farm?

We work with you to analyze your project requirements. Consider factors like total PV array capacity, inverter configuration, future expansion plans, and local grid requirements. Our engineering team provides technical support to select optimal voltage levels, capacity, and configuration for your specific application.

Q: What customization options are available?

We offer complete customization including rated voltage, capacity, short-circuit impedance, tapping range, connection group, and physical dimensions. Whether you need special protection ratings, unique mounting arrangements, or specific monitoring interfaces, we adapt our design to match your requirements.

Q: How long does manufacturing and delivery take?

Production timelines vary based on specifications and order quantity. Standard configurations typically require 6-8 weeks. Custom designs may need 10-12 weeks. We provide detailed project schedules and maintain communication throughout production to ensure your installation deadlines are met.
