When you're planning a photovoltaic power generation system, you need reliable equipment that can handle the unique challenges of solar energy. The SCB14 Dry-type Transformer for Solar Applications from Xuzhou Tuojie International Trade Co., Ltd. delivers exactly that. Our business-level system has very low no-load losses (≤0.7% of total capacity), a capacity range of 315 kVA to 3150 kVA, and Class H insulation that can withstand temperatures up to 180°C. We make transformers that go beyond IEC 60076 standards and use 20–30% less energy than older models. We have 18 patents, 15 top engineers, and over 120 sets of advanced production equipment.

When installing solar panels, you have to deal with special problems that regular transformers can't handle well.
Solar farms have to work in very harsh environments. In one day, temperature changes can be more than 80°C. Dust, dampness, and UV light are always putting tools at risk. It takes care of these problems right away with your SCB14 Dry-type Transformer for Solar Applications.
Unlike options that are filled with oil, our dry-type design doesn't pose any fire risks. There won't be any oil leaks that could hurt the environment. Even when the humidity level is 100%, the cast resin insulation gives better security.
Another problem is that inverters can cause harmonic distortion. String inverters and central inverters make noise in the electricity that can hurt regular transformers. Our system, which is rated K-13, handles these frequencies well, keeping THD below 5%.
Its heart is what makes it work. We use grain-oriented silicon steel, which cuts down on losses by 30 to 50 percent compared to regular steel. This directly leads to lower running costs over the equipment's 30+ year lifetime.
Vacuum pressure gelation (VPG) makes sure that there are no holes in the insulator. Every millimetre of plastic is perfectly shaped, so there are no weak spots that would cause it to break early.
The BWDK series signal thermometer checks the temperature right now. You get early signs before problems happen. Smart safety features go into action immediately to protect your investment.
Several sensors keep an eye on hot spots in the windings. You'll know right away if temperatures get close to levels that are worrying. This proactive method stops costly downtime before it happens.

Large installations demand robust equipment. In 50MW+ solar farms, our transformers step up voltage from 480V collector systems to 13.8kV or 34.5kV transmission levels.
Desert conditions don't faze these units. Sandstorms, extreme temperature variations, and high-altitude locations up to 4000m are all within operational parameters. The sealed design prevents contamination while managing complex electrical characteristics.
Your manufacturing facility, data center, or retail complex needs reliable power transformation. Units ranging from 100kVA to 2MVA handle step-down applications from utility 13.8kV to 480V/208V distribution.
Space constraints in urban settings require compact solutions. Our transformers deliver maximum power density while maintaining noise levels below 45dB. Fire safety requirements are easily met with non-flammable cast resin construction.
Microgrids and community solar projects benefit from bidirectional power flow capabilities. Capacity options from 500kVA to 5MVA suit various project scales.
Cloud transients cause rapid voltage fluctuations. Your transformer responds quickly, maintaining stable output. Battery energy storage integration works seamlessly. Smart grid protocols including DNP3 and IEC 61850 ensure communication compatibility.

You can operate at 100% humidity without concerns. After shutdown, the transformer returns to service immediately. No pre-drying procedures waste your time.
Non-flammable materials eliminate fire risks. You can install the unit directly at the load center, even in populated areas. Zero pollution means environmental compliance is guaranteed.
Low losses translate to reduced energy costs. Minimal partial discharge extends equipment life. Low noise levels keep neighbors happy. Superior heat dissipation allows 150% rated load under forced-air cooling.
Installation is straightforward. Once operational, you'll spend minimal time on maintenance. Overall operating costs drop significantly compared to oil-filled alternatives. In remote solar installations, this advantage is invaluable.
Our transformers power critical infrastructure across diverse sectors. The Xuzhou Rail Transit Network Control Center relies on our dual-circuit designs. XCMG Group's factory power supply upgrades were completed ahead of schedule. The GCL Photovoltaic Industrial Park demonstrates our solar expertise.

You'll see 20-30% lower no-load losses with SCB14 models. Enhanced thermal Class H insulation (versus Class F in SCB13) provides better temperature tolerance. Partial discharge performance stays below 10pC, exceeding industry standards.
Independent testing per IEC 60076-11 confirms superior efficiency under variable solar loading. Annual energy savings typically reach 15-25% in solar farm applications. Over a 30-year lifespan, these savings are substantial.
Our products incorporates K-factor ratings up to K-13. Specialized winding configurations minimize eddy current losses. Enhanced neutral sizing handles triplen harmonics effectively.
Third-party testing per IEEE 519 standards validates performance. Total harmonic distortion stays below 5% under typical inverter loading. Major inverter manufacturers including SMA, ABB, Schneider Electric, and Power Electronics have verified compatibility.
Design life exceeds 30 years based on accelerated aging tests per IEC 60076-14. UV exposure testing per ASTM G154 simulates 20 years of sun exposure in 2000 hours. Materials remain stable through thermal cycling and humidity testing.
Field installations in the Middle East and Southwest US provide real-world validation. Units operating for 15+ years continue performing to specification. Your investment is protected long-term.
Minimal maintenance keeps your costs low. Annual visual inspections identify obvious issues. Infrared thermography detects hot spots before they become problems. Comprehensive testing every 5 years includes insulation resistance and partial discharge measurements.
You won't perform oil sampling or complex procedures. Lifecycle costs drop 40-60% compared to oil-filled transformers. Remote locations benefit especially from this reduced maintenance burden.
Customizable impedance values (4-8%) accommodate various inverter topologies. Multiple secondary voltage configurations (480V, 690V, 4160V) match your specific requirements. Harmonic analysis and grid code compliance testing per UL 1741 confirms compatibility.
We've conducted proven compatibility testing with all major brands. Whether you're using string inverters or central inverters, our transformers integrate seamlessly.
