Filled with high-purity insulating transformer oil, the 220v to 110v oil immersed single phase transformer forms a closed circulating heat dissipation system. During long-term operation, the insulating oil quickly absorbs heat generated by copper windings and silicon steel cores, realizing passive rapid heat dissipation without auxiliary equipment. The fully sealed oil tank structure isolates internal components from external moisture, dust and corrosive gas, greatly enhancing overall insulation performance. This design enables both 25KVA and 33KVA models to maintain stable working temperature and electrical safety even in poorly ventilated and humid working environments.
2.3 Electrical Isolation & Ultra-Low Operating Loss
Designed with double-winding isolation structure, this high voltage electric power transformer completely isolates 220V input high voltage and 110V output low voltage, effectively filtering grid harmonics, surge current and electromagnetic interference. It delivers pure and stable power for terminal equipment and eliminates potential leakage risks. Equipped with high-quality grain-oriented silicon steel sheets and high-conductivity copper coils, the equipment greatly reduces no-load loss and operating power consumption. The low-loss design not only cuts down long-term operation costs but also ensures low-noise and energy-saving operation for daily power supply scenarios.
2.4 Compact Structure & Durable Long Service Life
Different from bulky three-phase transformers, this single phase oil immersed transformer adopts a streamlined integrated steel shell structure with small footprint and flexible installation. The integral welding process effectively prevents oil leakage, and the anti-corrosion shell adapts to indoor fixed installation and mild outdoor working conditions. All internal components are made of high-temperature and anti-aging materials, with strong overload resistance and short-circuit resistance. Under standard operating conditions, the service life of 25KVA and 33KVA models can exceed 30 years, minimizing later maintenance and equipment replacement costs for users.
