With an efficiency rating of over 99.5%, our Low Loss Oil Type Transformer performs admirably. Xuzhou Tuojie International Trade Co., Ltd. has 18 patents and more than 20 years of experience making transformers. Their cores are made of high-permeability grain-oriented silicon steel, and their windings are made of precision copper. With capacities from 30KVA to 31,500KVA, our S13-S22 line cuts no-load losses by 15–30% compared to standard models. With over 120 CNC machines and strict ISO9001 quality management, we've completed hundreds of projects successfully in the business, industrial, and local sectors, making sure that your power distribution stays efficient and reliable.

Why Choose Our Energy-Efficient Transformers?

Energy costs continue rising for industrial facilities worldwide. You need equipment that minimizes operational expenses while maintaining peak reliability.

Our transformers address your biggest challenges head-on.

Superior Energy Savings

You have to watch your budget for every kilowatt-hour. Our product is 0.5 to 2% more efficient than standard units. You'll save between 8,000 and 25,000 kWh a year with a standard 1000KVA system. That means lower power bills and a faster return on investment.

Our high-tech products are the key. We use high-quality silicon steel that has been cold-rolled and is grain-oriented. It has a magnetic flux density of 1.7 to 1.9 Tesla. This cuts core losses down to 0.1 to 0.3 percent of rated capacity.

Built for Demanding Environments

Your business can't have any downtime. We design transformers that can work in harsh situations.

The temperature range for use is from -40°C to +40°C. We can handle everything from the cold of the Arctic to the heat of the desert with our sealed tank design and flexible cooling systems. The oil-filled system does a better job of managing heat, so the temperature rise stays between 55 and 65°C above normal.

Need the ability to overload? Our units can handle 120% constant overload and quick changes in load, making them great for places where power needs change often.

Technical Excellence You Can Trust

Advanced Manufacturing Capabilities

Quality starts in production. Our facility operates over 120 sets of cutting-edge equipment:

• CNC automatic winding machines for precision conductor placement
• CNC static vacuum casting machines ensuring bubble-free insulation
• Automatic foil winding machines for uniform layer construction
• Microcomputer-controlled gradient curing furnaces for optimal thermal treatment

This sophisticated manufacturing process guarantees consistent quality across every unit.

Rigorous Quality Control

We do full inspections at every step of the way. From getting the raw materials to delivering the finished product, nothing is left out of the inspection.

Our quality management is based on the "zero defects" theory and follows ISO9001 standards. Before it is shipped, every transformer goes through electrical tests, checks for insulator resistance, and a turns ratio analysis.

Dielectric strength standards of 30–70 kV/2.5 mm are met by the shielding oil. To make sure long-term dependability, we do dissolved gas analysis (DGA) testing methods every year.

Proven Applications Across Industries

Utility Grid Substations

Distribution networks need to be as efficient as possible. Our 11kV-33kV/400V-690V transformers are used in residential and commercial places where even a 1% increase in efficiency can save a lot of money over 20 to 30 years.

Industrial Manufacturing Plants

Transformers that can work with ongoing job cycles are needed in places like steel mills, chemical processing plants, and heavy machinery. With a voltage control of less than 1%, our Low loss oil type transformer achieves more than 97% efficiency.

Because they don't make as much heat, they're perfect for small areas where controlling temperature is very important.

Renewable Energy Integration

Wind farms and solar panels need transformers that can smoothly handle loads that change. Our 690V-35kV step-up units have better short-circuit protection and quick load-following response for smooth grid synchronization.

Commercial Facilities

Consistent power quality is good for sensitive electronics in places like shopping malls, hospitals, and data centres. Clients usually cut running costs by 10 to 15 percent while making the system more reliable.

Key Advantages That Impact Your Bottom Line

Lower Total Cost of Ownership

Initial investment represents just one part of the equation. Operating costs over decades matter more.

Our transformers feature:

• 15-30% reduction in total losses compared to standard models

FAQ

Q: How much can I realistically save on energy costs?

You'll typically see 15-30% reduction in total transformer losses. For a 1000KVA unit, expect annual savings of 8,000-25,000 kWh. The exact amount depends on your load profile and operating hours. Many clients achieve ROI within 3-5 years through reduced electricity expenses alone.

Q: What maintenance schedule should I follow?

We recommend annual oil sampling and testing to monitor insulation quality. Conduct comprehensive electrical testing every three years, including insulation resistance and turns ratio measurements. Larger units benefit from internal inspection every five years. Continuous monitoring of load conditions and temperature helps optimize performance between scheduled maintenance.

Q: Will this transformer work with my renewable energy installation?

Absolutely. Our product handles variable loads exceptionally well. The 120% continuous overload capability and robust regulation systems accommodate wind and solar intermittency. We design units in compliance with IEEE 1547 standards for distributed energy resources and relevant grid codes.

Q: What's the expected service life?

Design life reaches 30-40 years with proper maintenance. Key longevity factors include regular oil quality management, controlled load cycling patterns, and ambient temperature management. We conduct accelerated aging tests per IEEE C57.91 to confirm insulation system durability. Many of our transformers installed decades ago continue operating reliably today.

Q: How does noise level compare to other transformers?

Our units operate at less than 45dB—quieter than normal conversation. This makes them suitable for noise-sensitive environments like hospitals, schools, and residential areas. The low noise results from precision core assembly and optimized magnetic circuit design.

Q: Can you customize specifications for special applications?

Yes. Our 15 senior engineers and over 30 intermediate technicians design tailored solutions for unique requirements. We accommodate various environmental conditions, country-specific voltage standards, and special cooling arrangements. Tell us your needs, and we'll engineer the right solution.

Q: What certifications ensure quality and safety?

All products hold ISO9001, ISO14001, and OHSAS45001 certifications. Our low-voltage equipment carries China CCC Mandatory Certification. Transformers comply with IEC60076, ANSI, IEEE, GB, and CSA standards. We've also earned CE and CSIT certifications along with prequalification from China Southern Grid and State Grid.
