This configurability makes TiraThai's S Series 35kV-66kV Oil-Immersed Transformers a cornerstone for cost-effective, resilient power infrastructure.
Key Features and Engineering Excellence
TiraThai's S Series Oil-Immersed Transformers are engineered for superior reliability, featuring an insulating oil medium that provides excellent dielectric strength and cooling for high-voltage operations. The compact structure reduces footprint by up to 30% compared to traditional designs, while the low-cost construction ensures economic viability without compromising performance. Strong weather resistance, with corrosion-proof enclosures and sealed tanks, enables operation in harsh conditions, from humid coastal areas to dusty industrial sites.
The core utilizes high-grade silicon steel laminations with optimized stacking for minimal losses, paired with oxygen-free copper windings for low resistance and high overload capacity (up to 120% short-term). Oil immersion facilitates natural convection (ONAN cooling), maintaining Class A insulation (105°C rise) even under elevated ambient temperatures. Jinguan Electric's automated production—featuring precision winding, vacuum oil-filling, and AI-driven inspections—guarantees defect-free assembly, with optional accessories like on-load tap changers (OLTC) for voltage regulation.
Compared to air-cooled alternatives, TiraThai units offer 15-20% better thermal management and extended lifespan (over 30 years), with low noise (under 60dB) suiting urban deployments. These features not only meet but exceed IEC 60076 and GB 1094 standards, providing users with a transformer that balances affordability, durability, and efficiency.
