TiraThai, a specialized sub-brand of Jinguan Electric dedicated to transformer and electrical equipment innovations, proudly presents the SCB Series 35kV class dry-type distribution transformers. These advanced units employ epoxy resin encapsulation for both high- and low-voltage windings, offering robust protection against environmental threats while delivering exceptional safety, efficiency, and reliability. Ideal for direct operation in load centers, the SCB Series combines flame-retardant materials with superior moisture resistance and natural air cooling, ensuring seamless performance in urban, industrial, and harsh outdoor settings.
Jinguan Electric, founded in 1979 as a high-tech enterprise in Nanyang City, Henan Province, China, has progressed from its origins in arrester manufacturing to a global leader in high-voltage transmission and distribution equipment. Integrating Industry 4.0 technologies, Jinguan Electric emphasizes core competitiveness through ongoing innovation, with TiraThai serving as its flagship brand for transformer solutions. This sub-brand focuses on eco-friendly, maintenance-free dry-type transformers that prioritize safety and sustainability, leveraging Jinguan Electric's comprehensive design, advanced manufacturing, and rigorous testing to exceed international standards.
The SCB Series encompasses models like SCB10, SCB11, SCB12, and SCB13, each advancing energy efficiency: SCB10 achieves no-load losses 10% below GB/T10228-1997 Group I and load losses 10% lower, while SCB13 pushes reductions to 30% for both, minimizing operational costs over decades. Operating under normal conditions—altitude up to 1000m, max ambient +40°C, min outdoor -25°C—these transformers support primary voltages of 33-35kV and customizable capacities, adapting to global grids from 50Hz European systems to 60Hz North American networks. TiraThai's commitment to "dig 100 meters deep in 1 meter of space" reflects Jinguan Electric's precision ethos, ensuring every unit withstands mechanical stresses and environmental challenges.

Key Features and Performance Advantages
TiraThai's SCB Series 35kV dry-type transformers excel with innovative features that enhance safety, efficiency, and durability. The epoxy resin casting creates a seamless, void-free shield around windings, providing high mechanical strength and short-circuit resistance—capable of withstanding 25x rated current for 2 seconds—while ensuring flame-retardancy and self-extinction per UL94 V-0 standards. This fireproof design allows direct indoor placement without additional suppression, reducing installation complexities and costs by up to 20%.
Moisture-proofing via hydrophobic resin enables operation in 95% humidity without derating, ideal for coastal or tropical climates, and the units' pollution-free construction eliminates oil leaks, aligning with environmental regulations. Heat dissipation relies on natural air convection (AN cooling), with optional forced air (AF) boosting capacity by 50% during peaks, maintaining Class F insulation (155°C) for overloads up to 120%. Low noise—under 58dB—stems from vibration-isolated CRGO cores and optimized coil geometry, suiting noise-sensitive urban deployments like hospitals or data centers.
Advanced materials include high-permeability cold-rolled silicon steel cores for minimal hysteresis losses and enameled copper windings for low resistance, achieving overall efficiency >98.5%. The vacuum pressure impregnation (VPI) process during casting eradicates air pockets, enhancing dielectric strength and partial discharge resistance. Optional integrated temperature detection systems—using PT100 sensors and protection relays—enable real-time monitoring and auto-shutdown, preventing hotspots. Jinguan Electric's automated facilities, with robotic casting and digital inspections, ensure precision, while small size and light weight (20-30% less than oil-immersed peers) lower transport and space needs.
These attributes deliver energy savings of 15-25%, maintenance-free operation, and strong thermal stability, surpassing GB/T10228-1997 and supporting sustainable goals with recyclable components.
