Xuzhou Tuojie International Trade Co., Ltd. brings you the SCB13 10kV-35kV High Efficiency Dry Type Transformer—a cutting-edge three-phase cast resin transformer engineered for superior performance. In comparison to earlier generations, this transformer offers no-load losses reduced by 25% and load losses reduced by 15%, with energy efficiency levels above national regulations by 10–15%. Each unit attains efficiency ratings of up to 98.5% with the support of our team of 15 senior engineers and 18 patents. Every transformer in our ISO 9001-certified production process satisfies stringent IEC60076 and IEEE standards, providing you with dependable operation in capacities ranging from 30KVA to 2500KVA across 10kV, 20kV, and 35kV voltage classes.

Your operating expenses are important. Our transformer's superior magnetic circuit design drastically lowers energy usage. While Class F insulation with Class B temperature increase (≤80K) maintains optimum efficiency during its more than 30-year lifespan, the advanced silicon steel core with magnetic flux density ≥1.7T minimizes power waste.
Peace of mind is something you deserve. Oil leakage hazards are completely eliminated by the epoxy resin vacuum casting method. Because it satisfies UL94-V0 requirements, its flame-retardant design is ideal for installation at load centres in high-rise buildings, schools, hospitals, and retail centres where fire safety is a top priority.
Your time is precious. Our dry-type solution requires no maintenance, in contrast to oil-filled transformers that need frequent oil sample and filtering. You only require thermographic scanning and yearly visual checks. Every five years, thorough testing guarantees steady performance without interfering with business activities.
Your installation environment is different. Our device runs at temperatures between -40°C and +40°C and can withstand humidity levels up to 100% with IP23 standard protection (IP54 optional). Specialized anti-corrosion coatings certified in accordance with IEC 60068-2-52 salt mist requirements are advantageous for coastal installations.

Even when things get tough, your transformer keeps working. It works normally at 100% humidity and goes back to work right away after being turned off—no need to dry it first. This tool keeps you from having to pay for repairs and downtime.
Your power bills go down by a lot. Because they lose 15% less load than regular models, you can see and feel the saves every month. When needed, forced-air cooling lets the machine work at 150% of its maximum load.
The place where you work stays quiet. Our transformer works at less than 50dB, so it can be put in places with noise restrictions, like hospitals, schools, and homes, without bothering the people who live there.
Your cash will be safe. The transformer can handle up to 0.4g of force from a quake and 25 times its stated capacity of short-circuit currents for 2 seconds. This keeps it working even when there are electrical problems.

Shopping complexes and office towers benefit from compact, safe installation. Our SCB13 10kV-35kV High Efficiency Dry Type Transformer fits basement electrical rooms where space is limited and fire codes are strict. Field data shows 99.7% uptime in major metropolitan deployments.
Chemical facilities, pharmaceutical factories, and food processing plants require contamination-free operation. The epoxy resin encapsulation resists corrosive atmospheres and temperature fluctuations. Installations in steel mills and petrochemical complexes demonstrate 15-year operational life with minimal intervention.
Solar farms and wind power stations demand rapid load response. With partial discharge levels ≤10pC, our transformer ensures stable grid connection. Utility-scale installations maintain 98% efficiency over 20+ years in outdoor environments with extreme weather conditions.
We've delivered transformers for Xuzhou Rail Transit Network Control Center, Xuzhou High-speed Railway East Station, and XCMG Group factory upgrades. These projects prove our capability to meet demanding specifications and tight schedules while maintaining exceptional quality.

Our facility operates over 120 sets of modern equipment, including CNC automatic winding machines, CNC static vacuum casting machines, and microcomputer-controlled gradient curing furnaces. This technology ensures consistent quality across every unit.
We implement comprehensive monitoring from raw material procurement through final delivery. Each transformer undergoes strict inspection at every production stage. Our "zero defects" philosophy integrated into ISO9001 management standards means unqualified products never leave our factory.
With 15 senior engineers, over 30 intermediate technicians, and 17 senior technicians, we provide expert guidance for your specific requirements. Our 18 patents demonstrate continuous innovation in transformer technology.

Q: How long will my SCB13 transformer last?
Your transformer is made to last for 30 years or more. Visual checkups, checks to make sure connections are tight, and thermographic scanning done once a year keep it going easily. Full testing every 5 years according to the IEEE C57.94 standard makes sure that it will always work without having to worry about oil upkeep.
Q: Will it perform well in coastal or high-humidity areas?
Of course. The IP54 protection class, along with a hydrophobic surface treatment and sealed terminal sections, keeps water harm from happening. Coastal sites have shown that they have been available 99.5% of the time for 15 years, even when the humidity was above 95%. Corrosion protection has been proven by salt mist tests according to IEC 60068-2-52.
Q: What about installation and transportation?
Your transformer comes fully tested and built at the plant. On-site, you only need to place it on the base and connect the power. Your investment is safe with climate-controlled shipping that includes shock tracking according to IEC 60076-1. For installation, links must meet pressure requirements, grounding must be checked according to IEEE 80, and commissioning tests must be done.
Q: Can it handle loads from variable frequency drives?
Yes, it's designed with K-factor ratings up to K-13 for nonlinear loads. Enhanced conductor sizing and improved core steel minimize harmonic heating. Independent testing per IEEE C57.110 confirms operation with total harmonic distortion up to 20% without derating.
Q: What warranty and support do you provide?
You receive a 25-year performance guarantee with comprehensive coverage for manufacturing defects. Our technical support team assists with specification selection, installation guidance, and troubleshooting throughout your transformer's operational life.
Q: How quickly can I receive my transformer?
Our proven project management delivered XCMG factory upgrades ahead of schedule. We maintain production efficiency to meet your timelines while ensuring every unit passes rigorous quality checks before shipment.
Q: Do you offer customization for special requirements?
Definitely. We provide tailored solutions for unique environmental conditions and country-specific standards. Whether you need special voltage configurations, enhanced protection ratings, or specific vector groups, our engineering team designs transformers matching your exact needs.
