Higher series like SCB12 and SCB13 further enhance these metrics with advanced core materials and winding designs, ensuring minimal energy waste over the transformer's lifespan. With primary voltages up to 10kV and customizable capacities, these transformers support seamless integration into diverse power systems, from compact urban installations to expansive industrial networks.
Transformer Model: SCB10 / SCB11 / SCB12 / SCB13 Series Primary Voltage Ratings: 6kV-10kV (Customizable) Secondary Voltage Ratings: 0.4kV (Customizable) Rated Capacity: 30-2500kVA (Customizable) Rated Frequency: 50/60Hz
This versatility allows TiraThai's dry-type transformers to adapt to global standards, facilitating easy deployment in regions with varying electrical requirements while prioritizing safety and longevity.
Key Features and Performance Advantages
TiraThai's SCB Series dry-type transformers excel through their robust construction and innovative features, setting them apart in the electrical industry. The epoxy resin encapsulation process creates a seamless, void-free barrier around the windings, enhancing mechanical strength and thermal conductivity for reliable operation under full load. This design inherently resists flames and self-extinguishes in case of arcing, eliminating the fire risks associated with oil-filled alternatives and complying with stringent safety codes like UL and CE.
Moisture-proofing is achieved through the resin's hydrophobic properties, allowing the transformers to operate in high-humidity environments without performance degradation—ideal for coastal or tropical installations. Heat dissipation occurs naturally via air convection (AN cooling), with optional auxiliary fans for forced air (AF) in high-density applications, maintaining temperatures within Class F (155°C) or H (180°C) insulation limits. Low-noise operation, typically under 55dB, results from vibration-dampened cores and optimized coil structures, making them suitable for noise-sensitive areas like hospitals or office buildings.
Material excellence defines the SCB Series: High-permeability, cold-rolled silicon steel cores minimize hysteresis losses, while enameled copper windings ensure low resistance and high overload capacity (up to 120% for short durations). The cast-resin process uses vacuum pressure impregnation (VPI) to eliminate air pockets, boosting dielectric strength and partial discharge resistance. Compared to traditional dry-types, TiraThai models reduce overall losses by 15-30% across series, translating to significant energy savings—potentially 10-20% lower operational costs annually for commercial users.
Jinguan Electric's automated manufacturing, including robotic coil winding and digital quality inspections, guarantees precision and consistency. Optional features like integrated temperature sensors and remote monitoring enable predictive maintenance, further extending service life to over 30 years. These advantages not only meet but surpass GB/T10228-1997 standards, positioning TiraThai as a leader in sustainable power distribution.
