As an upgraded equipment developed for high-load industrial scenarios, this type of transformer is equipped with the new-generation "NX2" optimized design, achieving dual breakthroughs in core performance and safety protection. Its iron core adopts a seamless wound structure, which fundamentally eliminates the magnetic resistance loss of traditional spliced iron cores. Combined with the fully sealed vacuum oil filling process, it not only reduces the dielectric loss value of the insulating medium by 15% but also effectively isolates moisture and impurities in the air, extending the service life of the insulation system.
