Leilang Electric's 100kVA single phase pole mounted transformer is professionally engineered for reliable 4.16kV to 120V voltage conversion, featuring two core competitive advantages: UL certification and high efficiency. Fully compliant with UL Subject 8750 safety standards, as well as ANSI, IEEE, IEC, and DOE energy efficiency requirements, it meets strict reliability criteria for North American residential, commercial, and light industrial overhead power distribution scenarios.
With official UL certification, it ensures full compliance with U.S. electrical safety regulations, enabling direct grid connection without additional modifications. Its optimized high-efficiency design, featuring a low-loss core and precision windings, achieves an efficiency rating of up to 99.25%, significantly reducing energy waste and long-term operating costs while aligning with global carbon neutrality goals.
Strictly manufactured in accordance with UL Subject 8750 safety standards, this transformer undergoes rigorous testing to ensure compliance with U.S. electrical safety regulations. It features a fully sealed oil-immersed tank with seamless welding and vacuum oil filling, preventing moisture, dust, and air ingress to avoid insulation failure and safety hazards.
High-creepage polymer bushings with anti-pollution and anti-rain flashover design enhance insulation reliability, while built-in current-limiting fuses and pressure relief valves provide additional safety protection. The transformer also incorporates a ground shielding design to reduce electromagnetic interference, further improving operational safety.
Adopts high-quality cold-rolled oriented silicon steel core with step-lapped lamination technology, minimizing hysteresis and eddy current losses. Windings are made of high-conductivity oxygen-free copper, processed with vacuum pressure impregnation (VPI) to reduce resistance loss and improve energy transfer efficiency.
This design not only achieves an efficiency rating of up to 99.25% but also complies with the latest DOE energy efficiency standards and GB 20052-2024 energy efficiency requirements, reducing long-term electricity costs for users and supporting energy-saving initiatives.
Optimized winding turns ratio and precision winding process ensure accurate voltage conversion from 4.16kV high voltage to 120V low voltage, with excellent load regulation performance. Even under fluctuating loads, it maintains stable output voltage, avoiding voltage surges or drops that damage electrical equipment.
Designed with 100kVA rated capacity, it is suitable for large-scale single-phase distribution scenarios, capable of supporting continuous operation of multiple electrical devices. It has strong overload capacity, able to withstand 120%-150% short-term load impact while maintaining stable efficiency and voltage output.
Designed for direct mounting on standard utility poles, with pre-installed brackets and clearly labeled terminals for quick on-site installation. The compact structure saves space, requires no large-scale civil engineering, and is suitable for various distribution network scenarios.
