The cylindrical transformer adopts a coaxial cylindrical structure, with symmetrical arrangement of windings and iron cores, compact volume and high mechanical strength. Its magnetic circuit is uniform, with low losses, and its efficiency is 3% -5% higher than traditional transformers. It has strong short-circuit resistance and low electromagnetic radiation. Optimized heat dissipation design, capable of stable operation in environments ranging from -40 ℃ to+125 ℃, with a protection level of IP65 or higher. Suitable for scenarios such as new energy, rail transit, and industrial automation, it combines the advantages of high efficiency, reliability, and environmental adaptability to provide stable power conversion for equipment.
