TiraThai, a specialized sub-brand of Jinguan Electric focused on transformer and electrical equipment innovations, proudly introduces the SCB Series 35kV Epoxy Resin Dry-Type Transformers. These advanced units serve as a superior replacement for oil-immersed distribution transformers, offering enhanced performance with low losses, strong insulation, and excellent overload capability. Engineered for indoor and outdoor use, the SCB series utilizes epoxy resin casting for windings and cores, providing fire safety, moisture resistance (up to 100% damp conditions), and robust thermal management, ensuring reliable operation in demanding urban and industrial power distribution scenarios.

Jinguan Electric, founded in 1979 as a high-tech enterprise in Nanyang City, Henan Province, China, has evolved from pioneering arrester manufacturing to a global leader in high-voltage transmission and distribution equipment. Embracing Industry 4.0 principles, Jinguan Electric drives core competitiveness through continuous innovation, with TiraThai serving as its premier brand for dry-type transformer solutions. This sub-brand leverages Jinguan Electric's rigorous quality control and advanced manufacturing to deliver SCB transformers that comply with international standards, including IEC 60076, GB/T 10228-1997, and IEEE C57.12.01. Certified by UL, CUL, CCC, CQC, CTQC, CE, and SGS, these units uphold ISO9001 (quality), ISO14001 (environmental), and ISO45001 (health & safety) management systems, ensuring exceptional safety and sustainability.

The SCB series, encompassing models like SCB10, SCB11, SCB12, and SCB13, achieves progressive efficiency gains: SCB10 reduces no-load losses by 10% below GB/T10228 Group I, while SCB13 pushes to 30% with optimized casting. Supporting primary voltages up to 35kV and capacities from 315kVA to 2500kVA, they operate at 50/60Hz with vector groups Dyn11 or Yyn0. TiraThai's philosophy—"dig 100 meters deep in 1 meter of space"—reflects Jinguan Electric's commitment to precision, delivering transformers that minimize environmental impact and maximize grid resilience.

Transformer Model: SCB Series (SCB10/SCB11/SCB12/SCB13) Primary Voltage Ratings: Up to 35kV (Customizable) Secondary Voltage Ratings: 0.4kV-10kV (Customizable) Rated Capacity: 315-2500kVA (Customizable) Rated Frequency: 50/60Hz

This versatility makes TiraThai's 35kV SCB Series Epoxy Resin Dry-Type Transformers a cornerstone for safe, efficient power infrastructure.

Key Features and Engineering Excellence

TiraThai's SCB Series Epoxy Resin Dry-Type Transformers are renowned for their vacuum casting process, which coats the core and completely encases the windings in epoxy resin, creating a seamless, void-free structure for superior insulation and heat dissipation. This design enables operation under 100% damp conditions without performance degradation, with strong overload capability (up to 120% short-term) and excellent fire safety—self-extinguishing per UL94 V-0 standards, eliminating oil leak risks.

The core employs high-permeability CRGO silicon steel with stepped-lap joints, minimizing no-load losses (10-30% below standards across the series), while enameled copper windings ensure low resistance and high efficiency (>98%). Natural air convection (AN cooling) maintains Class F insulation (155°C), with optional forced air (AF) for enhanced capacity. Low noise levels (under 55dB) result from vibration-dampened assemblies, suiting urban deployments.

Jinguan Electric's automated manufacturing—featuring robotic casting, vacuum impregnation, and AI inspections—guarantees precision, with customizable enclosures (IP20 to IP54) for dust/moisture protection. Compared to oil-immersed models, TiraThai SCB units reduce maintenance by 50% and energy losses by 15-25%, yielding substantial ROI. Optional smart features like temperature sensors enable predictive maintenance, aligning with Industry 4.0.

These features not only meet but surpass GB/T10228-1997 and IEC 60076 standards, positioning TiraThai as a leader in resilient, green power transformation.
