Key Features and Engineering Excellence
TiraThai's High Overload Dry-Type Transformers are renowned for their superior engineering, balancing extreme overload capability with minimal energy waste. The standout feature is the overload capacity exceeding 60%, enabling sustained performance during surges without excessive temperature rise, fully compliant with national standards for thermal management. Losses are optimized to as low as 5%, achieved through high-permeability CRGO silicon steel cores with stepped-lap joints and oxygen-free copper windings, reducing no-load and load losses by 20-30% compared to standard models.
Epoxy resin encapsulation creates a void-free, flame-retardant structure (UL94 V-0 rated), ensuring self-extinguishing properties and operation in 95% humidity without derating—perfect for harsh industrial environments. Cooling options include AN for baseline efficiency and AF for overload enhancement, maintaining Class F insulation (155°C) limits even under 60%+ loads. Low noise levels (under 55dB) stem from vibration-isolated designs, while the VPI process boosts dielectric strength and short-circuit withstand to 25x rated current for 2s.
Jinguan Electric's automated production—featuring robotic winding, vacuum impregnation, and AI quality scans—guarantees precision, with optional IP54 enclosures for added protection. Compared to conventional dry-types, TiraThai units cut operational costs by 15-25% through efficiency gains and extended lifespan (over 30 years). Integrated temperature sensors and overload relays provide proactive safeguards, aligning with smart grid requirements. These attributes not only meet but surpass GB/T 10228 and IEC 60076 standards, offering users a transformer that thrives in overload-intensive scenarios.
