In the process of planning a solar installation, ordinary transformers frequently fail to meet the requirements that are special to your project. The Custom PV Transformer that we offer is useful in this regard. Xuzhou Tuojie International Trade Co., Ltd. is responsible for the engineering of our transformers, which are customized to meet the requirements of solar power systems. Our solutions offer efficiency ratings that range from 98.5 to 99.2%, allowing you to optimize your energy production while simultaneously avoiding losses. We can make transformers with outputs between 30KVA and 31500KVA. During the manufacturing process, we use 18 patents, more than 15 top engineers, and more than 120 sets of new and improved production equipment. Our professional team has finished hundreds of successful commercial, industrial, and local projects, such as the GCL Photovoltaic Industrial Park. We also have a strict quality control system that makes sure there are no mistakes in the production process.

When it comes to your solar farm, you will want more than just a simple transformer. Your undertaking necessitates the utilization of apparatus that is capable of managing fluctuating power circumstances, severe weather, and stringent grid compliance regulations.
We are able to tackle these difficulties head-on with our transformers.
This is because conventional transformers were not designed to meet the specific requirements of solar systems. Power from solar systems is converted from direct current to alternating current, which necessitates accurate voltage conversion. In a smooth manner, our individualized solutions bridge the gap between the output of your inverter and the requirements of the grid.
Your solar equipment is subjected to harsh circumstances on a regular basis. Our transformers are able to sustain continuous performance in a wide range of temperatures, from 65 degrees Celsius in the desert to -40 degrees Celsius in the freezing cold. There is no need for pre-drying once the system has been shut down since the dry-type design is resistant to moisture, fractures, and environmental damage.
Your bottom line is immediately impacted by each and every percentage point of efficiency improved. The efficiency ratings of our transformers range from 98.5 to 99.2%, which is much higher than the overall performance of typical distribution transformers. This amounts to an enhanced energy production of 1.5-2.5% throughout the course of a project lifespan that lasts for 25 years.

Advanced Harmonic Management
Inverter-generated harmonics can damage standard transformers. Our units incorporate K-factor ratings (K-4 to K-13) with specialized winding configurations. This keeps Total Harmonic Distortion below 5%, ensuring compliance with IEEE 519 standards.
Flexible Customization Options
No two solar projects are identical. We tailor capacity, voltage specifications, and connection interfaces to match your exact requirements. Whether you're installing a 100kW rooftop system or a 500MW utility-scale farm, we've got you covered.
Intelligent Protection Systems
Our transformers feature intelligent temperature control that protects your investment. Low partial discharge design extends equipment lifespan. Fire-resistant, pollution-free construction allows safe installation directly at load centers.
Proven Reliability
We don't just manufacture Custom PV Transformer equipment—we engineer solutions. Our quality management follows ISO9001 standards with rigorous inspection at every stage. From raw material procurement to final installation, nothing leaves our facility without meeting strict specifications.
Utility-Scale Solar Farms
When you do big projects, you need strong tools. With our pad-mounted and substation transformers, which range from 5MVA to 40MVA, we can deal with different weather situations. Mounting that can withstand earthquakes, better cooling systems, and anti-corrosion treatments all work together to make sure that the system keeps working.
Commercial and Industrial Rooftops
In places where space is limited, solutions need to be very small. The noise level in our dry-type transformers, which have capacities from 500kVA to 5MVA, is less than 45dB. In addition to improving power supply in places with changing sun irradiation, they meet the safety standards for electricity in cities.
Distributed Microgrids
It is necessary for community solar projects to have the ability to flow power in both directions. Innovative protective techniques for islanding detection are included into our specialist transformers, which range from 300 kVA to 2 MVA. In rural areas with restricted access to maintenance, the inclusion of remote monitoring provides help for grid stabilization.

You deserve to know what goes into your transformer.
Advanced Production Capabilities
We operate over 120 sets of state-of-the-art equipment. CNC automatic winding machines ensure precision. CNC static vacuum casting machines create superior insulation. Microcomputer-controlled gradient curing furnaces optimize thermal properties.
Rigorous Quality Testing
Every transformer undergoes comprehensive testing before shipment:
Environmental Qualification
Your equipment must withstand real-world conditions. We conduct temperature cycling tests from -40°C to +85°C. Salt spray corrosion testing runs for over 2000 hours. UV exposure testing simulates decades of sun exposure.

Q: How quickly can you deliver a customized transformer?
Delivery times rely on what you want and how much you order. Standard setups usually ship between 6 and 8 weeks. Customizations that are more complicated may take 10 to 12 weeks. We've finished jobs early while keeping the quality high—just look at the upgrade we did for the XCMG Group plant.
Q: What maintenance does a dry-type transformer require?
Our dry-type style is great because it requires little upkeep. You won't have to change the oil or test the fluids often. Visual checks once a year and cleaning of ventilation holes on a regular basis are generally enough. The dry build takes away all worries about wetness.
Q: Can your transformers handle grid code requirements in different countries?
Of course. We create to a number of foreign standards, such as ANSI, IEEE, GB, and CSA. Our tech team makes sure that spread energy resources follow IEEE 1547. We'll work with you to make sure that your energy hookup needs are met.
Q: How do you ensure transformer efficiency over decades of operation?
It is made of high-quality silicon steel and has low core losses. Class H insulation methods are the best when it comes to keeping heat in. Our quality theory of "zero defects" means that every part meets the requirements. When you put something correctly and do little upkeep on it, it will work well for a long time.
Q: What cooling options work best for desert climates?
For extreme heat environments, we recommend our AF (Air Forced) cooling configuration. This provides enhanced heat dissipation when ambient temperatures exceed 40°C. We can also specify over-sized cooling capacity to maintain performance during peak temperature periods.
Q: Do you provide technical support after installation?
Yes. Our commitment extends beyond delivery. We offer installation guidance, commissioning support, and ongoing technical consultation. With 15 senior engineers and over 30 intermediate technicians on staff, you'll have expert assistance throughout your project's lifetime.
